OTRS Installation in Ubuntu 12.04

Installation:

Ubuntu already has a package for OTRS in the repositories. Before start installation OTRS we have to install MySql, Apache.

1)  Install MySQL 5

sudo apt-get install mysql-server mysql-client

Password for MySQL root user:

New password for the MySQL "root" user:  <-- yourrootsqlpassword
Repeat password for the MySQL "root" user:  <-- yourrootsqlpassword

* To check whether the MySQL server is running:

sudo netstat -tap | grep mysql

* When you run this command, you should see the following line or something similar:

tcp        0      0 localhost:mysql         *:*                LISTEN      2556/mysqld

* If the server is not running correctly, you can type the following command to start it:

sudo service mysql restart

2) Install Apache2

* Apache2 is available as an Ubuntu package, therefore we can install it like this:

sudo apt-get install apache2

Now direct your browser to http://192.168.0.100, and you should see the Apache2 placeholder page (It works!):

After completion I and II installation, we will move to OTRS Installation:

3) Installing OTRS:

* Basic ubuntu 12.04 LTS, fully updated:

sudo aptitude update 

sudo aptitude dist-upgrade

@ Source

* Get a copy of a recent version of OTRS from the OTRS site (http://www.otrs.com/en/open-source/get-otrs/software-download/)

wget http://ftp.otrs.org/pub/otrs/otrs-3.2.9.tar.gz

* Extract the archive

tar -xzf otrs-3.2.5.tar.gz

* Move the extracted directory to its permanent location

sudo mv otrs-3.2.5 /opt/otrs

@ Users and Permissions

* OTRS needs to run as its own user. So we need to create some folders and files:

sudo useradd -r -d /opt/otrs/ -c 'OTRS user' otrs

sudo usermod -g www-data otrs

cd /opt/otrs/Kernel

cp Config.pm.dist Config.pm

cp Config/GenericAgent.pm.dist Config/GenericAgent.pm

* Now we need to set permission

cd /opt/otrs/bin

sudo ./otrs.SetPermissions.pl --otrs-user=otrs --otrs-group=otrs --web-user=www-data --web-group=www-data /opt/otrs

@ Perl Modules

cd /opt/otrs/bin

sudo ./otrs.CheckModules.pl

* The following command should fix the failed Perl modules.

sudo aptitude install liblwp-useragent-determined-perl libapache2-reload-perl libnet-smtp-ssl-perl libnet-smtp-tls-butmaintained-perl

* And Some extra modules that should prove to be useful (i.e. PDF functionality, LDAP connectivity, etc.).

sudo aptitude install libgd-gd2-perl libgd-graph-perl libgd-text-perl libjson-xs-perl libnet-dns-perl libyaml-libyaml-perl libpdf-api2-simple-perl libtext-csv-xs-perl libxml-parser-perl libmail-imapclient-perl libnet-ldap-perl

@ Configuration

* Apache2

cp /opt/otrs/scripts/apache2-httpd.include.conf /etc/apache2/conf.d/otrs.conf 

service apache2 restart

sudo cp -va /opt/otrs/scripts/apache2-httpd.include.conf /etc/apache2/sites-available/otrs

cd /etc/apache2/sites-available/

sudo chown root:root otrs

sudo a2ensite otrs

sudo service apache2 reload

@ Finalization

* Go to http://127.0.0.1/otrs/installer.pl with your web browser.


All the best...!
