Installing OTRS on CentOS 5

The rpm-packages for CentOS can easily be downloaded from http://otrs.org/download/ . Install with yum

wget http://ftp.otrs.org/pub/otrs/RPMS/fedora/4/otrs-2.4.5-01.noarch.rpm
yum install --nogpgcheck otrs-2.4.5-01.noarch.rpm

Don’t forget to disable selinux.

call in your browser http://yourserver.com/otrs/installer.pl and setup the database.

Now install the otrs cronjobs

sudo -u otrs /opt/otrs/bin/Cron.sh

this installs the otrs cronjobs in /var/spool/cron/otrs

Now you just have to setup basic otrs-stuff, like queues and Postmaster-configs. But everything over the otrs web interface.
