Unix Installation and Updating Help

In this page you'll find all the necessary software you need to install and update LAMS 2.0.x versions using the unix installer. If you need to restore the backup created by the updater, see Revert to Other Backup.

If you want to build LAMS from source, you can follow the instructions in Building LAMS.

Before You Run the Installer/Updater...

Make sure you have the software LAMS needs! If you are unsure of what software is needed to run LAMS, go to the Development Environmentpage.

Installing all Pre-required Software

MySQL Database Server

See the Installing MySQL page. You can install MySQL on another server to the one running LAMS - the Unix/Linux installer will install LAMS on one server with MySQL running on another server.

Java SE Development Kit (JDK)

LAMS requires the Sun JDK 5 or 6. See the Installing Java page for more details.

Wildfire Jabber Server

For our Chat tool, we use the Wildfire Jabber Server. See the Installing Wildfire page.




Suggested Location




4.0.3SP1 and 4.0.4 have problems running LAMS, so 4.0.2 is your best bet until we fix the problem.

After installing JBOSS, check that the script bin/ is executable. If it is not then it must be made executable.

To check, go to /usr/local/jboss-4.0.2/bin and do "ls -l". The result should be something like - the "x"s are the important bit:

-rwxr-xr---  1 root  agroup  4681 Sep  9 19:30

If it is just:

-rw-r--r--   1 root  agroup  4681 Sep  9 19:30

then you need to do "chmod ug+x *.sh" to change it.

Installing all Pre-required Software in Ubuntu

We tent to use Ubuntu server and these are the quick steps we take to set up LAMS:

Ubuntu Feisty (7.04)

This will install Sun Java JDK 1.5, Ant and MySQL 5.0 Server

Packages required for LAMS2

Now, let's get JBoss Appserver

Get JBoss

Wildfire Jabber server:

Get JBoss

See instructions on how to install WildFire

Downloading LAMS for Unix

Check that you have the latest LAMS 2 Unix installer

See the downloads page.

If you are updating LAMS

Make sure you have the previous version of LAMS installed. You can find out what version you can update to on the downloads page

You are strongly recommended  to backup your LAMS installation before updating to prevent losing any of the data you may have saved while using your current LAMS installation. The updater will prompt you to ask whether you want an automatic backup, otherwise you can backup manually by following the steps.

If your MySQL database is on a different server then you must backup yourself manually as the updater cannot do it for you!

  1. Backup the JBoss directory that contains your current LAMS installation
  2. Backup you repository directories. These are the directories specified by the $LAMS_DIR variable in
  3. Backup /etc/lams2 if it exists
  4. Dump the LAMS database by using the following MySql command, filling in the fields inside the brackets.
    > mysqldump -u(database username) -p(password) (lams database name) > (backup dir)/lams.dump

Running the installer/updater

Once you have your installer, extract it into any desired location eg: /tmp/installer;

Editing the File

The file outlines where and how you will install LAMS, It also configures some of the settings you want for the install.

If you have an existing file from a previous LAMS installation in /etc/lams2, then you do not need to change the file - the installer will pick up the file in /etc/lams2 and use it automatically.

Most of the default configurations in can be left, but you will need to change some to suit the setup of your personal machine. The file comes with directions on what you need to alter and what needs to be left unchanged. Pay particular attention to "Essential Settings" section because LAMS will not install or run properly if these are incorrect. Below is the skeleton for the file.

Setting up the Language Locale

You will see about a quarter of the way through the file there is a line that says: 


In LAMS you can set the defualt language of your server to be one of many languages, and more to come, see the internationalization page. Look out for unix language packs to add to your list of language locales.

The locale options for LAMS-2.0 available are listed below, simply put in your file (under Installation Options):

LOCALE - (locale)
LOCALE_DIRECTION - (locale direction)




English    (Australia)                  



Español    (Spanish)

Running the Installer

Before you run the script, you need to ensure that your $JAVA_HOME is set to your java 1.5 or higher directory, also you will need to set the $PATH variable
to include the path to the java binaries. The steps to do this are listed below.
> JAVA_HOME="(path to java installation directory)"
> export JAVA_HOME
> PATH="(path to java bin directory):$PATH"
> export PATH

If you are running MySQL on a separate server, then you will need to set up the database before doing the installation. See "Setting up MySql on a Different Server" in the readme file for the details on creating the database and setting up the appropriate privileges.

If you are running MySQL on the same server as LAMS, you do not need to do any further database configuration - the installer will do it for you.

Once you have finished editing file you are ready to run the
install script. Go to the root directory of the package and type:
> sudo ./

The installer will ask you if you wish to set up lams as a service, this will make lams start automatically each time you boot your machine. The installer will attempt to detect the wrapper jar that is suitable for you, if it cannot you can choose the wrapper that is the closest to suiting your architecture

You can find out your architecture types by typing
> uname -a    to get all the information
> uname -m    to get the architecture type

wrapper-linux-ppc-64-3.2.3    Linux    PPC
wrapper-linux-x86-32-3.2.3    Linux    i386    
wrapper-linux-x86-64-3.2.3    Linux     IA64

More information about setting the wrapper up in unix can be found here.

Running the Updater

Before you run the script, you need to ensure that your $JAVA_HOME is set to your java 1.5 or higher directory, also you will need to set the $PATH variable
to include the path to the java binaries. The steps to do this are listed below.
> JAVA_HOME="(path to java installation directory)"
> export JAVA_HOME
> PATH="(path to java bin directory):$PATH"
> export PATH

Check that you still have your file in \etc\lams2. If you do, you do not need to modify the file in the installation directory. If the file is not in \etc\lams2, then you will need to edit the file that comes with the upgrader.

Go to the root directory of the package and type:
> sudo ./

The installer will ask you whether you want to stop LAMS before updating. Unless you have already done so yourself, it is HIGHLY RECOMMENDED that you let the updater run the shutdown script for LAMS, otherwise the update will not run correctly. Also it is recommended that you backup LAMS before the upgrade, the upgrade script gives you this option, or you are also free to do so yourself.

If you are having trouble shutdown LAMS sometimes (and it has happened on some servers) then see the readme file for instructions on stopping LAMS manually.

Note: You should leave MySQL and Wildfire running.

Running Lams

If you chose to installed LAMS 2.0 without the wrapper, you should be able to run LAMS 2.0.2 by simply going into the <jboss-4.0.2 dir>/bin and typing:

>sudo ./

This is a new script added by LAMS 2.0.2. It was not in LAMS 2.0.

After a couple of minutes LAMS 2.0 will have started. In your browser type the server URL that you specified in the lams.configuration file, and you should be at the lams homepage.

To shutdown LAMS 2.0 go to (jboss directory)/bin and type:
> sudo ./ -S

LAMS 2.0 will take a few moments to shut down. To check if LAMS 2.0 has shut down correctly, type the following on Linux:
> ps -ef | grep java

Or type the following on Macintosh
> ps -A | grep Java

Using the Java Wrapper

If you chose to install the Java Service Wrapper, LAMS will start automatically when you boot your machine and stop when you turn off your machine.

You can also start and stop LAMS manually by going to the jboss-4.0.2/bin directory and using these commands.

> sudo ./lams2 start        (starts LAMS)
> sudo ./lams2 console   (start LAMS in current shell, to stop do ctrl+C)
> sudo ./lams2 stop        (stops LAMS)
> sudo ./lams2 restart    (restarts LAMS)
> sudo ./lams2 status     (tells you if LAMS is currently running)
> sudo ./lams2 dump     (send a kill -3 signal to the wrapper causing the JVM to do a full thread dump)

For more information about using the Jave Service Wrapper with LAMS, go to the web tutorial
