Starting with OTRS 3.1.12 and upcoming OTRS 3.2.0beta5, we will have specific RPM packages which should be used when installing OTRS on Red Hat Enterprise Linux (RHEL) 5 or 6, or its derivatives, CentOS and Oracle Enterprise Linux.
Previously, there was one RPM available, marked ‘Fedora’, that should be used to install on both Fedora and Red Hat Linux and its derivatives. However, package names on the different Linux versions differ. This caused a few problems recently; and we mitigate this now by providing separate packages for RHEL5, RHEL6, and Fedora. These packages are available from our download page since a few days already.
If you run OTRS on RHEL or CentOS, and previously installed OTRS by using the Fedora RPM, you can simply upgrade it by using the RHEL RPM and following the standard upgrade procedures; there are no special steps needed.
Creating specific RPMs for RHEL and CentOS also allows us to better specify which dependencies are needed for installation of OTRS; the upcoming OTRS 3.2 beta 5 RPMs will also install all available Perl modules from the base repositories. For Fedora, all additional Perl modules are available in the repositories, which improves the installation experience a lot. For RHEL, not all dependencies are available. We recommend using Enterprise Packages for Enterprise Linux (short ‘EPEL’), a Fedora initiative for providing high quality packages to RHEL/CentOS Linux, to install any additional packages not available in the base repositories.
