This tutorial assumes database server for the tracker is already up and running on a same or another machine. The tutorial based on RHEL 4 Install Guide and another one guide slightly modified to conform CentOS 5 / RHEL 5 changes and facilitate software installation. Apache2/mod_perl2 with RT 3.8 are used in the tutorial. You may want to review Manual Installation Requirements and Manual Installation to get a grip of the installation process.
Perform a standard install of CentOS 5 or RHEL 5. Enable "centosplus" repository in the /etc/yum.repos.d/CentOS-Base.repo. Download and install RPMforge distribution.
Install Apache and mod_perl:
# yum install httpd httpd-devel apr-devel mysql-client mysql-devel mod_perl
...and also some CPAN module dependencies...
# yum install freetype-devel gd-devel libjpeg-devel libpng-devel xorg-x11-devel
Install ncftpget, it's required by some CPAN modules. In case you don't use x86_64 look for an appropriate build.
# rpm -i ftp://rpmfind.net/linux/EPEL/4AS/x86_64/ncftp-3.2.0-3.el4.x86_64.rpm
