This page contains installation tips for [[LAMS]]. Mostly LAMS 2.1RC1 for Solaris 10.
This page contains installation tips for a '''fresh''' install of [[LAMS]].


LAMS is a JAVA/JBOSS-based application and needs some installation skills on Windows and good installation skills for Unix.
LAMS is a JAVA/JBOSS-based application and needs some installation skills on Windows and good installation skills for Unix.


== LAMS 2.0 RC2 Windows XP PC ==
Note: I put the legacy stuff in the [[Talk:LAMS_installation_and_configuration|discussion page]], e.g. LAMS 2.x for Ubuntu, LAMS 2.1RC for Solaris


Note: This chapter is outdated (written in Dec 2006). I don't see really the point in running a LAMS server on a personal PC and our servers are Unix.
== LAMS 4.5+ ==
As of July 2021, LAMS 4.5 was released and is the latest stable release.  


Do not try to install LAMS if you lack basic installation experience and technical '''reading skills'''. Here are just a few remarks in addition to the [http://wiki.lamsfoundation.org/display/lamsdocs/Windows+Installer+Help LAMS installation instructions]. I also strongly suggest to look at the [http://lamscommunity.org/dotlrn/clubs/technicalcommunity/forums/forum-view?forum_id=4929 Problems Installing LAMS] Forum.
=== Getting the LAMS source code ===
Source code is available from [https://github.com/lamsfoundation/lams Github]. The code branch to use is v4.5


=== Other Software ===
'''Required software'''
* Git
* Wildfly 14.0.1
* OpenJDK 11
* MySQL 8.0
* Ant  (Java task compiler)


To run it on windows you need to install other software.
==== OpenJDK 11 ====
* Java JSE 5.0 (update 9), ''not just the JRE''. Get it from [http://java.sun.com/javase/downloads/index.jsp Sun].
In Debian/Ubuntu 20.04
* MySQL: Get it directly from [http://dev.mysql.com/downloads/ MySQL] and take the '''Installer version''' (not the zip installation).
** Install it and remember the password
** I suggest '''not''' installing/using a [[WAMP]] environment for LAMS 2RC 2. The LAMS installer 2Rc2 could not find MySQL in my WampServer environment even if it was told where to look for in the LAMS installer.
** Hack would be to manually edit the registry with this [http://dev.mysql.com/doc/refman/5.0/en/windows-install-wizard.html information] from MySQL AB and [http://lamscommunity.org/dotlrn/clubs/technicalcommunity/forums/message-view?message_id=118753 this posting] and [http://lamscommunity.org/dotlrn/clubs/technicalcommunity/forums/attach/download/win_registry_msql%2ejpg?object_id=118756&attachment_id=118758 picture] by Ernie Ghiglione. Basically one needs to reproduce the MySQL entry from the official MySQL AB installer:
HKEY_LOCAL_MACHINE
  SOFTWARE
    MySQL AB
      MySQL Server 5.0 
                          Location c:\wamp\mysql
                          Version  5.0.27
... but this still didn't work for me. Something I did not try was to add mysqladmin.exe to the bin directory which is missing (see: [http://lamscommunity.org/dotlrn/clubs/technicalcommunity/forums/message-view?message_id=341725 Jun-Dir Liew]'s question and try it ... I don't have the time to do it right now. E.g. this file may be part of the simple zip / no registry version from the MySQL site).


=== MySQL ===
$ sudo apt install openjdk-11-jdk-headless
$ sudo apt install fontconfig
==== MySQL 8.0 DB ====


* If you use a WAMP package you must know where MySQL sits. E.g. c:\wamp\mysql if you work with "WampServer" (but see above that I failed, rather work with an "official MySQL installer from MySQL AB). If you use the official MySQL installer, there will be no problem.
$ wget https://dev.mysql.com/get/mysql-apt-config_0.8.15-1_all.deb
$ sudo dpkg -i  mysql-apt-config_0.8.15-1_all.deb
$ sudo apt update
$ sudo apt install mysql-server
$ sudo mysql_secure_installation


=== LAMS ===
===== Basic MySQL configuration =====
''/etc/mysql/mysql.conf.d/mysqld.cnf''


* Make sure that the LAMS port (8080) is free, e.g. install [http://www.download.com/Active-Ports/3000-2085_4-10062969.html Active Ports] or type something like ''netstat -a'' in a DOS terminal.
...
# LAMS stuff

...
 
After installing MySQL, create a user and a DB for LAMS and grant appropriate permissions:


* LAMS has an installer and if you got the above right it will install without problems. You may have a firewall. In this case make sure to open the necessary ports. Also pay attention to popup blockers in your navigator. LAMS worked fine with both IE 6 and Firefox 1.5x.
DROP DATABASE IF EXISTS lams;
CREATE DATABASE lamsdb DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;
SET FOREIGN_KEY_CHECKS=1;
GRANT ALL PRIVILEGES ON lamsdb.* TO lamsdbuser@localhost IDENTIFIED BY 'real_secret_pw';
REVOKE SUPER ON *.* from lamsdbuser@localhost;


== LAMS 2.1x on On Solaris ==
==== Wildfly 14.0.1 ====


Lams 2.0 was released on December 6 2006. Since then, there were very several minor upgrades.
$ wget https://download.jboss.org/wildfly/14.0.1.Final/wildfly-14.0.1.Final.tar.gz
On March 2008, the current releases are 2.0.4 (stable) and 2.1 (RC1). These installation notes refers mostly
$ cd /opt/lams
to the 2.1RC1 install, but it should help with 2.0.4 too. Official LAMS instructions are a bit Linux centric and this is main reason why you might have a look at this.
$ tar xvzf wildfly-14.0.1.Final.tar.gz


First, read the instructions in:
==== LAMS source code pre-compilation ====
* [http://wiki.lamsfoundation.org/display/lamsdocs/Unix+Installer+Help Unix Installation and Updating Help] (if you plan to use the unix installer)
LAMS is open source and its code is available from [https://github.com/lamsfoundation/lams GitHub]<syntaxhighlight lang="bash">
* [http://wiki.lamsfoundation.org/display/lams/Building+LAMS Building LAMS] (if you plan a source install)
git clone https://github.com/lamsfoundation/lams.git
* [http://wiki.lamsfoundation.org/display/lams/Development+Environment Development Environment]
</syntaxhighlight>By default branch is LAMS' latest stable release as of July 2021, that's version 4.5. If you need a previous branch, see [https://github.com/lamsfoundation/lams/branches other branches available].


Disclaimer: I am not a good sysadmin nor is it my idea of fun. This is not a manual, but '''just''' my private installation notes I am willing to share. - [[User:Daniel K. Schneider|Daniel K. Schneider]] 18:30, 20 March 2008 (MET)
Wherever you have your LAMS v4.5 code, edit the following files


So, open a terminal under root ....
'''common.properties'''


=== Prerequisite 0: Infrastructure ===
Primarily the DB settings and based system.


* Make sure your organization doesn't stiffle your creativity with Firewalls. If they do, expect '''a lot''' of
If you are building LAMS using Windows, set the osPropertiesName to "windows" instead of "unix".  
extrawork.
* Also the 8080 port should be free. Some software like Skype just randomly take up ports. If you run an other server, read [http://wiki.lamsfoundation.org/display/lamsdocs/Changing+Server+Ports+for+LAMS Changing Server Ports for LAMS]
* Hardware: Any Windows, Linux, MacOS X, Solaris etc. machine will do since LAMS is programmed in JAVA. You just need some diskspace and memory. Also, you may have to adapt some scripts to your special unix brand.


=== Prerequisite 1: Java software ===
...
#======== DATABASE PROPERTIES =========
db.host=localhost
db.port=3306
db.name=lamsdb
db.username=lamsdbuser 
db.password=real_secret_pw
...
osPropertiesName=unix
...


; Java + ant
''If you are building LAMS in a unix based system, then change the file '''unix.properties.''' If you are using Windows, then change the '''windows.properties''' file instead.''


* Solaris 10 ought to have the right Java + Ant installed. Ant is an installation program like make.
'''unix.properties'''


Check if Java can be found, i.e. type:
Here you will need to figure a path to the content repository
java -version
contentrepository.base=/var/opt/lams
... you should have java 1.5.x or better. If you don't, check the system for another java or install a new one. If you do so, make sure to specify the right path according to instructions from the LAMS install page.


=== Prerequisite 2: Wildfire ===
The path to your Wildfly folder
server.home=/usr/local/wildfly-14.0.1/


This is a [http://en.wikipedia.org/wiki/Xmpp XMPP] (Jabber) chat server, that actually is called Openfire now.  See:
...  
* [http://wiki.lamsfoundation.org/display/lamsdocs/Installing+Wildfire+for+LAM Installing Wildfire for LAMS]
  contentrepository.base=/var/opt/lams
* Also read [http://www.igniterealtime.org/builds/wildfire/docs/latest/documentation/install-guide.html Installation guide] (at Igniterealtime).
...  
server.home=/opt/lams/wildfly-14.0.1/
...  


You don't really need open/wildfire (but then either your students can't chat). You also may try to use an existing server that works with LAMS. I guess that there ought to be free servers you can use.
==== Compilation and deployment ====
* LAMS folks say to install an '''old''' 2.6.2. version. Links are available from the LAMS page, you won't find it at [http://www.igniterealtime.org/ Ignite realtime]. Note: I have to see whether this is still true, but for the moment I just complied.
* Since this server is written in Java you can take the [http://www.igniterealtime.org/builds/wildfire/wildfire_2_6_2.tar.gz Mac OSX and others] version (i.e. a tar ball).


Installation steps:
cd lams_build
ant deploy-lams


1) Uncompress in /usr/local/wildfire or some other place
If no errors occurred, you are ready to start Wildfly.


2) Start the server with ./bin/wildfire start
cd /opt/lams/wildfly-14.0.1/bin
* This is a typical startup script. You later can copy this script to /etc/init.d/ etc.  
./standalone.sh


3) Configure this server through the web interface. If you are lucky you will have a web browser on your server and an X11 connection.
http://localhost:9090/
Else use an URL like:  http://yourhost.org:9090/ ... it should work I think. But do it as fast as possible since you have to set passwords and stuff.


* Use "embedded database" if you want to make the install shorter, else you can set it up with mysql
LAMS should be available at localhost:8080/lams/ 


The configuration process will ask you to fill in a few forms. Just make sure that you use the right server names. You then can log as administrator and you will have access to an administration console.
By default, LAMS has a set of preconfigured users:
{| class="wikitable"
|+Default Users
!user
!password
!role
|-
|sysadmin
|sysadmin
|System administrator
|-
|test1
|test1
|Teacher, student, tutor
|-
|test2
|test2
|Teacher, student, tutor
|-
|test3
|test3
|Teacher, student, tutor
|-
|test4
|test4
|Teacher, student, tutor
|}
Of course, you can create and import users and courses into LAMS at any time from the sysadmin menu.  


* Tick "Don't Show History" (Group Chat -> History Settings), but you can do this later
(OPTIONAL) Wildfly comes with a ton of libraries that LAMS does not use. So to slim Wildfly to only use the libs that LAMS uses, please run the following ant task in the lams_build folder: <syntaxhighlight lang="bash">
ant slim-standalone
</syntaxhighlight>  


4) Test it. You may want to install a [http://en.wikipedia.org/wiki/List_of_Jabber_client_software jabber client], e.g. gajim (Ubuntu users can read [https://wiki.ubuntu.com/Jabber Jabber]
== LAMS 3.1 ==


5) Security
As of March 2019, we do have a new LAMS installation that works fine in virtual server running Ubuntu 18.x.
You may restrict login to given set of IP addresses or even disable account creation. Chat servers may be taken over by not so friendly people.
* Edit Server Settings->Registration and Login


Installing wildfire should be easy, it was for me. It's a fairly popular product...

=== Prerequisite 3: Configure MySQL for LAMS ===
However, I do not feel doing system administration anymore (except for this wiki) and I asked our systems person to do it. So there is not documentation, sorry.


Here are the steps:
Lams Moodle integration. There are two types of integration.
* LAMS - Moodle integration with a Moodle plugin.
* [[IMS Learning Tools Interoperability|LTI]] integration, i.e. Moodle can "consume" LAMS contents


1) Make sure to have a MySQL '''5.x''' server. Else install it (and come back)
=== LTI external tool integration ===


2) Configure it according to the [http://wiki.lamsfoundation.org/display/lamsdocs/Installing+MySQL+on+Windows+for+LAMS instructions]
Documentation
* [https://docs.moodle.org/36/en/External_tool_settings External tool settings] (Moodle 3.6 manual).
* [https://wiki.lamsfoundation.org/display/lams/Integrations Integrations] (LAMS documentation).


Edit file my.cnf according to the instructions
An administrator can manually configure external tools in Site administration > Plugins > Activity modules > External tool> Manage tools so that they are available across the site.  
* This cnf file may not exist (it wasn't in our binary distribution). Also, it can be in different locations
* Type ''mysql --help'' to get a list of the places the MySQL server will look for this config file
* Create my.cnf if you don't have one. Start by copying a *.cfn model from /usr/local/mysql/share/mysql or some other place. I took my-medium.cnf.


In particular, my.cnf should include these lines (no idea what it means and why):
=== Moodle LAMS integration through a Moodle plugin ===


[mysqld]
* We did that with LAMS 2.5. To be tested with LAMS 3.0. There is a [https://wiki.lamsfoundation.org/display/lams/Integrations plugin for download] and the method should be the same.
....
transaction-isolation=READ-COMMITTED
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"


Then restart mysql !
== LAMS 3.0 ==


3) Create a LAMS database.
As of November 2018, the current system is LAMS 3.x. You can test this with a [https://demo.lamsfoundation.org/lams/ demo version]. '''Below, we started documenting an installation on Ubunt 18x, but we did not find time to complete the installation'''. As you can see something went wrong. Instead, we installed LAMS 3.1 on a virtual server machine.


If you upgrade, you may want to make a dump for safeguarding or alternatively kill all tables if you want a fresh start. I personally enjoy destroying whole databases.
'''History'''


Then create:
LAMS 2.5 was initially promised for 2014. Then, after a funding cut, the LAMS team was mostly disbanded and the core team found a new "home" in Singapour. Sometimes in 2016 the version number was changed to LAMS 3.0.
* a database named "lams"
* a user "lams"
* Make to sure to have it run in UTF-8 mode !


Best way to to this is to use a terminal client and type something this:
'''Status as of Nov 2018'''
mysql -u root -p


Then enter the following lines (alternatively read them from a file)
* The old LAMS community pages are still online, but no longer maintained.
SET FOREIGN_KEY_CHECKS=0;
DROP DATABASE IF EXISTS lams;
CREATE DATABASE lams DEFAULT CHARACTER SET utf8;
SET FOREIGN_KEY_CHECKS=1;
GRANT ALL PRIVILEGES ON *.* TO lams@localhost IDENTIFIED BY 'secretpassword';
REVOKE PROCESS,SUPER ON *.* from lams@localhost;
quit


=== Prerequisite 4: JBOSS ===
* LAMS 3.x it is available on [https://github.com/lamsfoundation/lams Github], but documentation is lacking. Also, there is no installer. You will have to install and configure like in the "good" old times ....
** LAMS 3.x will run under old 8.2.1 version of [http://wildfly.org/downloads/ Wildfly], formerly JBoss (?). E.g. see [https://www.howtoforge.com/tutorial/ubuntu-wildfly-jboss-installation/ How to install WildFly (JBoss) Java Application Server on Ubuntu 18.04].
** Create a MySQL database
** Build the system with ANT


JBOSS is a Java application server. LAMS is programmed with this application framework.
* https://demo.lamsfoundation.org/lams/ does run a 3.x demo version for which you can require a login.


* I simply got the 4.0.2 binary from [http://labs.jboss.com/portal/jbossas/download Jboss.org]
* LAMS 3.x is available as commercial offering through [https://www.lamsinternational.com/ Lams International] and also through content services (to be verified).


* Unpackage into /usr/local
gtar xzf jboss-4.0.2.tar.gz -C /usr/local


* Copy some jar files
cp /usr/local/jboss-4.0.2/server/all/lib/jboss-cache.jar /usr/local/jboss-4.0.2/server/default/lib/
cp /usr/local/jboss-4.0.2/server/all/lib/jgroups.jar /usr/local/jboss-4.0.2/server/default/lib/


=== LAMS source file download ===
=== Prerequisites ===


Get the archive from the [http://wiki.lamsfoundation.org/display/lams/Downloads downloads] page.
;Java
: Usually, this is installed. Check it. In principle, the Open JDK should work, however we do not know if that is true for older version. If it does not (we have to test) this, then it should be replaced with Oracle one. '''This is very likely the case'''.
java -version
gives something link:
openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1, mixed mode)


Direct links: this may change !
Installation did not work with java 11, so I tried '''OpenJDK version 8'''. If you don't have Java 8 (it already was on my system), install it first.


* [http://saturn.melcoe.mq.edu.au/installers/lams-unix-installer-2.0.4.tar.gz lams 2.0.4 Australian mirror]
udo apt install openjdk-8-jdk
* [http://lamscommunity.org/2.0/stable/unix/lams-unix-installer-2.0.4.tar.gz lams 2.0.4 UK mirror]


Note: If you want to play with a release candidate, it's an option to get a more recent version from the CVS software archive. Some bug already may have been fixed. On the other hand, you may encounter a new one. You can browse the [http://lamscvs.melcoe.mq.edu.au/cgi-bin/viewcvs.cgi/ lams cvs repository]. To get the code from CVS, consult [http://wiki.lamsfoundation.org/display/lams/Building+LAMS building lams]) and then build from source.
To use Java 8 by default, you can do the following. Most software seems to use Java 8 anyhow ....
sudo update-alternatives --config java


=== Pre-install configuration ===
(tested with LAMS 2.1 RC1)


0) Read the "readme" file you will find and/or again [http://wiki.lamsfoundation.org/display/lamsdocs/Unix+Installer+Help Unix Installation and Updating Help]. It's authorized gospel, this is not.
;SASS (some kind of CSS pre-processor)
sudo apt install sass


1) Decide where the files should go. Either use a typical unix installation with files
;Ant
all over the place or put all LAMS related stuff in some directory, e.g. /usr/local/lams.
sudo apt install ant
I prefer the second solution, since this way I can get rid of unwanted software easily...


2) Dezip the installer in some place, e.g. /src/lams
;If exists, stop your old LAMS, e.g.
gtar -xvf lams-unix-installer-2.1-RC1.tar.gz
: /etc/init.d/lams2 stop


3) Then edit the '''lams.properties''' file according to [http://wiki.lamsfoundation.org/display/lamsdocs/Unix+Installer+Help unix installer help].
=== Kill old LAMS ===
This file sits in the install directory.


Make a backup first
We did not try to upgrade an old LAMS installation since we did not have many sequences that were worthwhile keeping and since there are no instructions on how to do this. So, export sequences that are worth keeping ...
cp lams.properties lams.properties.ORI
Then I did this (as I said I prefer all files in one place for experimental systems). Make sure that you correctly enter db and user names, locations and so forth !
Basically there are three sections:


1) Related to installation
; Remove the startup script for old lams (or similar if it exists)
grep -R lams /etc
: For example
rm /etc/rc6.d/K02lams2
rm /etc/rc5.d/S02lams2
rm /etc/rc4.d/S02lams2
rm /etc/rc3.d/S02lams2
rm /etc/rc2.d/S02lams2
rm /etc/rc1.d/K02lams2
rm /etc/rc0.d/K02lams2


LAMS_DIR=/usr/local/lams/lams
=== Install and configure Wildfly ===
DB_NAME=lams
DB_USER=lams
DB_PASS=secret
   
   
2) If you have wildfire, make sure to specify the name of host machine, etc.
# cd /src
wget http://download.jboss.org/wildfly/8.2.1.Final/wildfly-8.2.1.Final.tar.gz
tar xvfz wildfly-8.2.1.Final.tar.gz


3) Installation settings again, I had to change nearly each line ! Make sure to have each line right.
sudo mv /src/wildfly-8.2.1.Final /opt/wildfly
sudo chown you:you /opt/wildfly
cd /opt/wildfly
more README.txt 


Port number. If you change this, you also have to reconfigure JBOSS (I don't know where)!
#Now test
  LAMS_PORT=8080
cd /opt/wildfly/bin
./standalone.sh
# If your X server works and if you got Firefox installed on the server machine
firefox --new-instance
  http://localhost:9990


Server URL (certainly not localhost). E.g. you want something like:
=== Create a new MySQL database and user ===
SERVER_URL=http://tecfasun1.unige.ch:8080/lams/


=== Using the installer ===
(1) Check what you got
(tested with LAMS 2.1 RC1)


* Reminder: Read [http://wiki.lamsfoundation.org/display/lamsdocs/Unix+Installer+Help Unix Installation and Updating Help]
mysqlshow -p -u root


If you did the above (editing lams.properties) alright, then make sure again that Java can be found. In principle, on Solaris systems this is the case and you can ignore instructions about setting the JAVA_HOME. To check, just type:
(2) Create a new database and user
 
    
echo $JAVA_HOME
  mysql -u root -p
 
and copy/paste an adapted version of the following
In a csh shell you may fix the path like this (if needed):
<source lang="sql">
setenv PATH /usr/java/bin/:$PATH
DROP DATABASE IF EXISTS lams3;  
 
CREATE DATABASE lams3 DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;  
In a Bash shell:
SET FOREIGN_KEY_CHECKS=1;
export PATH=/usr/java/bin/:$PATH
GRANT ALL PRIVILEGES ON lams3.* TO lams@localhost IDENTIFIED BY 'real_secret_pw';
 
REVOKE PROCESS,SUPER ON *.* from lams@localhost;
Then install, i.e. type:
</source>
./install-lams.sh
 
... most likely it won't work, read on.
 
; RC2 install script does not work on Solaris
 
If it fails (with the one script I got it did), use debugging modes first, e.g.:
sh -x ./install-lams.sh
sh -v ./install-lams.sh
sh -vx ./install-lams.sh
 
Now to fix the RC1 problems:
 
1) First repair a bourne shell error, i.e. you either have to make the script a bash shell (best choice):
#!/usr/bin/bash
or alternatively make the following change (next best):
   # export JAVA_HOME=$ORIG_JAVA_HOME
:must become
JAVA_HOME=$ORIG_JAVA_HOME
export JAVA_HOME
or just comment out the following lines (On Solaris 10 Java will be found):
# checkJava
  ....
# export JAVA_HOME=$ORIG_JAVA_HOME
 
2) Then there was Linux specific line to be fixed:
# cp -rv assembly/lams.ear ${DEFAULT_DIR}/deploy
cp -r assembly/lams.ear ${DEFAULT_DIR}/deploy
 
; Success
You are successful when you see this:
LAMS 2.1-RC1 Configuration completed!
Please view the README for instructions on how to run LAMS.
 
=== Deploying and running LAMS ===
 
First time you will start up JBOSS it will take some time deploying LAMS as a web application.
 
There is a startup script you will find in the JBOSS/bin directory. It just configures JAVA for more memory and then launches the original run.sh script from JBOSS.
./usr/local/jboss-4.0.2/bin/run-lams.sh
 
This also will fail with RC1. Read on ...
 
==== Fixing the script ====
 
In 2.1RC2 I had to fix the script, or actually just use something different.
 
1) Missing shell identification. Add the following as first line:
#!/usr/bin/bash
 
Note: You have to use Bash not sh (/usr/bin/sh), since the LAMS folks use bash syntax. This line:
export JAVA_HOME="/usr/java"
is wrong in traditional Bourne shell. Should read:
JAVA_HOME="/usr/java"
  export JAVA_HOME
 
2) There wasn't enough heap space
E.g. from the log file (/usr/local/jboss-4.0.2/server/default/log/)
2008-03-20 11:26:15,574 ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with
name 'coreSessionFactory' defined in class path resource
[org/lamsfoundation/lams/commonContext.xml]: Initialization of bean failed; nested
exception is java.lang.OutOfMemoryError: Java heap space
java.lang.OutOfMemoryError: Java heap space
 
I first doubled initial and max heap with no effect, something does not pass from this script to the next one.
# export JAVA_OPTS="-server -Xms256m -Xmx512m -XX:MaxPermSize=256m"
export JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:MaxPermSize=256m"
Or maybe JAVA_OPTS will have contradictory info like (a good sysadmin would try to dig and understand ...)
-server -Xms128m -Xms512m ...
 
Anyhow, I then just decided to modify the JBOSS start-up script and use it directly.
Around line 141 of file '''run.sh''' I inserted more initial and max heap and I also took $JAVA_OPTS out since for some strange reason it already was set with unwanted -XMs .Xmx.
JAVA_OPTS="-Xms512m -Xmx512m -Dprogram.name=$PROGNAME"
#JAVA_OPTS="$JAVA_OPTS -Dprogram.name=$PROGNAME"
 
==== Start and stop LAMS ====
 
To start LAMS, go to the JBOSS bin directory:
cd /usr/local/jboss-4.0.2/bin/
Try first:
./run-lams.sh
If it doesn't work, fix heap space in the run.sh file directly (as explained above) and run it:
./run.sh &
To avoid getting all the traces in the terminal
./run.sh > /dev/null &
 
Then you should get this (e.g. last line in the log file). If not, search for errors.
2008-03-20 12:03:21,967 INFO  [org.jboss.system.server.Server] JBOSS (MX MicroKernel)
[4.0.2 (build: CVSTag=JBoss_4_0_2 date=200505022023)] Started in 1m:52s:938ms
 
To stop LAMS, just stop the JBOSS server. If it won't work, just kill the big hanging Java process.
./shutdown.sh -S
 
Always consult the log file when in doubt (the first time you start JBOSS it will take some time to install LAMS).
tail ../server/default/log/server.log
 
==== LAMS first test ====
 
If you you are here, then LAMS ought to run, e.g. try a URL like:
http://tecfasun1.unige.ch:8080/lams/
 
If you forgot the login name and password, you can retrieve it from
/src/lams/lams-unix-installer-2.1-RC1/lams.properties
 
=== Configuration ===
 
To be continued. Basically, I managed to get the MOODLE interface working (see below).
 
== Legacy notes for a lams 2.0 Solaris install ==
 
When I installed LAMS for the first time, the install had to be done manually. At some point I'll try again a manual install. For now, understand please that some things may have changed.
 
=== LAMS pre-build configuration ===
 
I configured the following entries in the following files. Most entries are related to file paths.


In lams_build directory:
After aborting wildfly you can run intot the following type of error (see also [https://lamscommunity.org/dotlrn/clubs/technicalcommunity/forums/message-view?message_id=1069554 this], dated 07/14/10)

  update patches set patch_in_progress = "F";
 
  File: lams/lams_build/common.properties

File: lams/lams_build/unix.properties
=== Dowload, configure and build LAMS ===
  contentrepository.directory=/usr/local/lams/repository


Change this in '''three''' locations !!
In order to find these files again, we decided to put them in /opt but any place can do.
File: lams_build/conf/unix/jboss/service/mysql-ds.xml
    <password>XXXX</password>


In lams_common directory:
sudo chown you:your_group /opt/lams
cd /opt/
git clone https://github.com/lamsfoundation/lams.git


File: lams/lams_common/db/sql/insert_unix_config_data.sql
'''Edit the configuration files'''

  ('SMTPServer','mail.tecfa.unige.ch');
  ('LamsSupportEmail','webmaster@tecfa.unige.ch');
  ('ContentRepositoryPath','/usr/local/lams/repository'); 


... Don't miss the port number for the server URL (e.g. 8080) !
cd /opt/lams/lams_build


In the same directory you may change the admin login and password (not tested !)
* Make a copy of the *.properties files just be sure. In addition, do not change the properties files themselves since they may be overridden by upgrades. Put them into a file called build.properties.
File: lams/lams_common/db/sql/insert_users.sql 


Note: I did not find an LamsHome property in any file (''this conflicts with the installation instructions'').
Change common.properties:
db.host=localhost
db.port=3306
db.name=lams3
db.username=lams.....
db.password=real_secret....


=== What if you have another server running on port 8080 ? ===
Change file unix.properties:
# Maybe not the best place for you, but at TECFA we always create a /data directory for data that must be kept, e.g. portalware, web server files, etc.
contentrepository.base=/data/lams


You can run JBOSS on a different port, but need to edit a few files. Read this:
#JBoss deploy directory (Unix)
server.home=/opt/wildfly


* [http://wiki.lamsfoundation.org/display/lamsdocs/Configuring+Multiple+LAMS+Instances+on+One+Machine Configuring Multiple LAMS Instances on One Machine] (LAMS)
#Sass executable.  
* [http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfiguringMultipleJBossInstancesOnOneMachine ConfiguringMultipleJBossInstancesOnOneMachine] (JBoss)
sass_exec_file=/usr/bin/sass


=== Make directories for lams  ===
'''Copy the properties to file''' <code>build.properties</code>
They must match the above of course


mkdir /usr/local/lams
'''Build LAMS'''
mkdir /usr/local/lams/temp
mkdir /usr/local/lams/dump
mkdir /usr/local/lams/repository


I don't know who runs JBoss, so I just deprotected for some quick playing ...
It is not clear to me if one should build various components. In principle, lams-cruise alone should do the trick.
chmod -R 777 /usr/local/lams


=== Build ===
# go to the build directory
Type the following commands ''in this order''. (You don't need Ecplise to build LAMS). But stop the JBOSS server when you do this.
  cd /opt/lams/lams_build
  cd /src/lams/lams_build


  ant rebuild-db
  # Optional: build some stuff
  ant assemble-ear
  ant build-db
  ant deploy-ear
  ant deploy-ear  
  ant deploy-tools
  ant deploy-tools
ant copyfiles


=== Run it ===
  # build lams (ant will read the build.xml file and "cruise" is a "target" that should build the whole thing)
  cd /usr/local/jboss-4.0.2/bin/
  ant lams-cruise
  ./run.sh &


The adminstrator login is '''sysadmin''' (don't forget this)
At the end you should see something like:
lams-cruise:
BUILD SUCCESSFUL
Total time: 3 minutes 35 seconds


The sysadmin login password is in the SQL file below. You may change it before you build, I was quite frustrated not to able to log in ;)
Now, in principle, LAMS is deployed in the Wildfly sever and could launch it again.
/src/lams/lams_common/db/sql/insert_users.sql


=== Server configuration ===
=== Compilation errors with OpenJDK 11 ===
See [http://www.lamsinternational.com/documentation/advanced_p.php?g=configure Configuring your LAMS Server].


* Java may not have enough heap space (it runs out of memory). Replace the 256 with something bigger. I think that the run.sh has to be fixed. Otherwise it may be the Tomcat config somewhere.
Some library is missing with openjdk '''11''' and something else is wrong. I did not get these errors with Openjdk 8, but then I might have installed some extra libraries in the past. I cannot remember.

=== Things I did wrong ===
=== Test running LAMS with WildFly ===


Now for some human touch ....
Make sure that the port that you plan to use with WildFly is free. By default the standalone server version is port 8080.


* Forget to specify the OS
#Now test
* Forgot to add the port number of the server URL
cd /opt/wildfly/bin
* Forgot to create the lams directory
./standalone.sh
* Only changed password in one location in lams_build/conf/unix/jboss/service/mysql-ds.xml


=== Debuging ===
This will take some time since it will have to digest LAMS.
Look at files in:
/usr/local/jboss-4.0.2/server/default/log/
Then stop JBoss,
cd /usr/local/jboss-4.0.2/bin/shutdown -S &
Repair misconfigurations above, rebuild with ant and run it again :)
I don't know if global cleaning up is an efficient idea, but I do it anyhow as a last resort when I get stuck, e.g.:
# Execute ''ant clean''
# Drop the lams database (and don't forget to create it again)
# Empty the JBoss server/default/deploy/lams.ear/ directory ?

I managed this to work somewhat with LAMS 2.1RC1. I failed with an early LAMS 2.0 version - [[User:Daniel K. Schneider|Daniel K. Schneider]] 18:30, 20 March 2008 (MET).

I did not yet use in production so far. But I inserted the [http://www.lamscommunity.org/dotlrn/clubs/educationalcommunity/highered//lams-seq/sequence?seq%5fid=19738  Beyond the VLE] module through Moodle. I was able to:
Else if you ran it as background process:
* use with Moodle student ID's (test and test2)

** not use with Moodle student ID's as monitor (that's correct)
* use it with Moodle admin ID as student and monitor

Definition

This page contains installation tips for a fresh install of LAMS.

LAMS is a JAVA/JBOSS-based application and needs some installation skills on Windows and good installation skills for Unix.

Note: I put the legacy stuff in the discussion page, e.g. LAMS 2.x for Ubuntu, LAMS 2.1RC for Solaris

LAMS 4.5+

As of July 2021, LAMS 4.5 was released and is the latest stable release.

Getting the LAMS source code

Source code is available from Github. The code branch to use is v4.5

Required software

  • Git
  • Wildfly 14.0.1
  • OpenJDK 11
  • MySQL 8.0
  • Ant (Java task compiler)

OpenJDK 11

In Debian/Ubuntu 20.04 

$ sudo apt install openjdk-11-jdk-headless
$ sudo apt install fontconfig

MySQL 8.0 DB

$ wget https://dev.mysql.com/get/mysql-apt-config_0.8.15-1_all.deb
$ sudo dpkg -i  mysql-apt-config_0.8.15-1_all.deb
$ sudo apt update
$ sudo apt install mysql-server
$ sudo mysql_secure_installation
Basic MySQL configuration

/etc/mysql/mysql.conf.d/mysqld.cnf 

...
# LAMS stuff
explicit_defaults_for_timestamp
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
transaction-isolation=READ-COMMITTED
sql-mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"
max_allowed_packet=32M
# Record slow queries
slow_query_log = 1
slow_query_log_file = /var/log/mysql/mysql-slow.log
long_query_time = 10

[mysqldump]
default-character-set=utf8mb4
hex-blob=1
single-transaction=1
quick=1
...

After installing MySQL, create a user and a DB for LAMS and grant appropriate permissions: 

DROP DATABASE IF EXISTS lams;
CREATE DATABASE lamsdb DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;
SET FOREIGN_KEY_CHECKS=1;
GRANT ALL PRIVILEGES ON lamsdb.* TO lamsdbuser@localhost IDENTIFIED BY 'real_secret_pw';
REVOKE SUPER ON *.* from lamsdbuser@localhost;

Wildfly 14.0.1

$ wget https://download.jboss.org/wildfly/14.0.1.Final/wildfly-14.0.1.Final.tar.gz
$ cd /opt/lams
$ tar xvzf wildfly-14.0.1.Final.tar.gz

LAMS source code pre-compilation

LAMS is open source and its code is available from GitHub

git clone https://github.com/lamsfoundation/lams.git

By default branch is LAMS' latest stable release as of July 2021, that's version 4.5. If you need a previous branch, see other branches available.

Wherever you have your LAMS v4.5 code, edit the following files

common.properties

Primarily the DB settings and based system.

If you are building LAMS using Windows, set the osPropertiesName to "windows" instead of "unix". 

... 
#======== DATABASE PROPERTIES =========
db.host=localhost
db.port=3306
db.name=lamsdb
db.username=lamsdbuser  
db.password=real_secret_pw
...
osPropertiesName=unix
...

If you are building LAMS in a unix based system, then change the file unix.properties. If you are using Windows, then change the windows.properties file instead.

unix.properties

Here you will need to figure a path to the content repository contentrepository.base=/var/opt/lams

The path to your Wildfly folder server.home=/usr/local/wildfly-14.0.1/ 

... 
contentrepository.base=/var/opt/lams 
... 
server.home=/opt/lams/wildfly-14.0.1/
...

Compilation and deployment

cd lams_build
ant deploy-lams

If no errors occurred, you are ready to start Wildfly. 

cd /opt/lams/wildfly-14.0.1/bin
./standalone.sh


LAMS should be available at localhost:8080/lams/

By default, LAMS has a set of preconfigured users:

Default Users
user password role
sysadmin sysadmin System administrator
test1 test1 Teacher, student, tutor
test2 test2 Teacher, student, tutor
test3 test3 Teacher, student, tutor
test4 test4 Teacher, student, tutor

Of course, you can create and import users and courses into LAMS at any time from the sysadmin menu.

(OPTIONAL) Wildfly comes with a ton of libraries that LAMS does not use. So to slim Wildfly to only use the libs that LAMS uses, please run the following ant task in the lams_build folder: 

ant slim-standalone

LAMS 3.1

As of March 2019, we do have a new LAMS installation that works fine in virtual server running Ubuntu 18.x.

However, I do not feel doing system administration anymore (except for this wiki) and I asked our systems person to do it. So there is not documentation, sorry.

Lams Moodle integration. There are two types of integration.

  • LAMS - Moodle integration with a Moodle plugin.
  • LTI integration, i.e. Moodle can "consume" LAMS contents

LTI external tool integration

Documentation

An administrator can manually configure external tools in Site administration > Plugins > Activity modules > External tool> Manage tools so that they are available across the site.

Moodle LAMS integration through a Moodle plugin

  • We did that with LAMS 2.5. To be tested with LAMS 3.0. There is a plugin for download and the method should be the same.

LAMS 3.0

As of November 2018, the current system is LAMS 3.x. You can test this with a demo version. Below, we started documenting an installation on Ubunt 18x, but we did not find time to complete the installation. As you can see something went wrong. Instead, we installed LAMS 3.1 on a virtual server machine.

History

LAMS 2.5 was initially promised for 2014. Then, after a funding cut, the LAMS team was mostly disbanded and the core team found a new "home" in Singapour. Sometimes in 2016 the version number was changed to LAMS 3.0.

Status as of Nov 2018

  • The old LAMS community pages are still online, but no longer maintained.
  • LAMS 3.x is available as commercial offering through Lams International and also through content services (to be verified).


Prerequisites

Java
Usually, this is installed. Check it. In principle, the Open JDK should work, however we do not know if that is true for older version. If it does not (we have to test) this, then it should be replaced with Oracle one. This is very likely the case.
java -version

gives something link: 

openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1, mixed mode)

Installation did not work with java 11, so I tried OpenJDK version 8. If you don't have Java 8 (it already was on my system), install it first. 

udo apt install openjdk-8-jdk

To use Java 8 by default, you can do the following. Most software seems to use Java 8 anyhow ....
sudo update-alternatives --config java


SASS (some kind of CSS pre-processor)
sudo apt install sass
Ant
sudo apt install ant
If exists, stop your old LAMS, e.g.
/etc/init.d/lams2 stop

Kill old LAMS

We did not try to upgrade an old LAMS installation since we did not have many sequences that were worthwhile keeping and since there are no instructions on how to do this. So, export sequences that are worth keeping ...

Remove the startup script for old lams (or similar if it exists)
grep -R lams /etc
For example
rm /etc/rc6.d/K02lams2
rm /etc/rc5.d/S02lams2
rm /etc/rc4.d/S02lams2
rm /etc/rc3.d/S02lams2
rm /etc/rc2.d/S02lams2
rm /etc/rc1.d/K02lams2
rm /etc/rc0.d/K02lams2

Install and configure Wildfly

# cd /src
wget http://download.jboss.org/wildfly/8.2.1.Final/wildfly-8.2.1.Final.tar.gz
tar xvfz wildfly-8.2.1.Final.tar.gz 

sudo mv /src/wildfly-8.2.1.Final /opt/wildfly
sudo chown you:you /opt/wildfly
cd /opt/wildfly
more README.txt   

#Now test
cd /opt/wildfly/bin
./standalone.sh
# If your X server works and if you got Firefox installed on the server machine
firefox --new-instance
http://localhost:9990

Create a new MySQL database and user

(1) Check what you got 

mysqlshow -p -u root

(2) Create a new database and user 

mysql -u root -p

and copy/paste an adapted version of the following 

DROP DATABASE IF EXISTS lams3;  
CREATE DATABASE lams3 DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci; 
SET FOREIGN_KEY_CHECKS=1; 
GRANT ALL PRIVILEGES ON lams3.* TO lams@localhost IDENTIFIED BY 'real_secret_pw'; 
REVOKE PROCESS,SUPER ON *.* from lams@localhost;

After aborting wildfly you can run intot the following type of error (see also this, dated 07/14/10) 

/opt/wildfly/bin$ 18:25:34,136 INFO  [JdbcMigrationLauncher]   If this isn't from a long-running patch, but a stale lock, either:
18:25:34,136 INFO  [JdbcMigrationLauncher]     1) run MigrationTableUnlock (probably 'ant patch.unlock')
18:25:34,136 INFO  [JdbcMigrationLauncher]     2) set the lockPollRetries property so the lock times out
18:25:34,136 INFO  [JdbcMigrationLauncher]        (this is dangerous in combination with long-running patches)
 18:25:34,136 INFO  [JdbcMigrationLauncher]     3) set the 'patch_in_progress' in the patches table to 'F'

In the LAMS DataBASE, run the following SQL 

update patches set patch_in_progress = "F";

Dowload, configure and build LAMS

In order to find these files again, we decided to put them in /opt but any place can do. 

sudo chown you:your_group /opt/lams 
cd /opt/
git clone https://github.com/lamsfoundation/lams.git

Edit the configuration files 

cd /opt/lams/lams_build
  • Make a copy of the *.properties files just be sure. In addition, do not change the properties files themselves since they may be overridden by upgrades. Put them into a file called build.properties.

Change common.properties: 

db.host=localhost
db.port=3306
db.name=lams3
db.username=lams.....
db.password=real_secret....

Change file unix.properties: 

# Maybe not the best place for you, but at TECFA we always create a /data directory for data that must be kept, e.g. portalware, web server files, etc.
contentrepository.base=/data/lams

#JBoss deploy directory (Unix)
server.home=/opt/wildfly

#Sass executable. 
sass_exec_file=/usr/bin/sass

Copy the properties to file build.properties

Build LAMS

It is not clear to me if one should build various components. In principle, lams-cruise alone should do the trick. 

# go to the build directory
cd /opt/lams/lams_build

# Optional: build some stuff
ant build-db
ant deploy-ear    
ant deploy-tools

# build lams (ant will read the build.xml file and "cruise" is a "target" that should build the whole thing)
ant lams-cruise

At the end you should see something like: 

lams-cruise:
BUILD SUCCESSFUL
Total time: 3 minutes 35 seconds

Now, in principle, LAMS is deployed in the Wildfly sever and could launch it again.

Compilation errors with OpenJDK 11

Some library is missing with openjdk 11 and something else is wrong. I did not get these errors with Openjdk 8, but then I might have installed some extra libraries in the past. I cannot remember.

Test running LAMS with WildFly

Make sure that the port that you plan to use with WildFly is free. By default the standalone server version is port 8080. 

#Now test
cd /opt/wildfly/bin
./standalone.sh

This will take some time since it will have to digest LAMS. 

# If your X server works and if you got Firefox installed on the server machine you can see something on the server.
firefox --new-instance
http://localhost:8080

Shutting down the test server

  • CTRL-C in the console

Else if you ran it as background process: 

jboss-cli.sh --connect --command=:shutdown
