Unix Installation and Updating Help

In this page you'll find all the necessary software you need to install 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.

MySQL Database Server

See the Installing MySQL page.

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

D:\ (Windows) | /usr/local/jboss-4.0.2 (Unix)



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

 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.

  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.
    > $sqldir/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: /usr/local. 

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. Most of the default configurations 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)

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

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

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 wrapper, then you should have a few extra files in your <jboss-4.0.2 dir>/bin, namely "" and "wrapper". Make these executable by typing:

chmod a+x *

If you wish to make LAMS a service that starts every time your machine starts up, you need to copy the init.d script ( into the /etc/init.d folder. For more inforamtion about setting up a service, see  the web tutorial
