- RT 4.4.1 installation on CentOS 7.2.1511 -
Assumptions: 1. Access to the internet and CentOS OS and update repositories is available. 1. Installation testing was completed using CentOS 7.2.1511 minimal boot ISO.
Installation Steps: 1. Install OS. Install the OS from ISO or PXE boot using your normal methodology.
* Install prerequisites for RT from OS repository. * yum install expat gd graphviz mariadb-server openssl expat-devel gd-devel graphviz-devel mariadb-devel openssl-devel perl perl-CPAN wget screen mod_fcgid * yum groupinstall "Development Tools" "Web Server"
1. Patch OS
* yum update * reboot (unless you are doing step 4 immediately)
1. Disable selinux, by editing /etc/sysconfig/selinux:
* SELINUX=disabled * reboot
1. Adjust local services:
* systemctl enable mariadb.service * systemctl enable httpd.service * systemctl start mariadb.service * systemctl stop httpd.service
* NOTE: httpd service needs to be stopped to allow RT web based configuration later in process.
1. Configure root password for mariadb:
* mysqladmin -u root password * NOTE: configure the internal DB password for the local instance of mysqld or mariadb
1. Install CPAN minus.
* curl -L http://cpanmin.us | perl - --sudo App::cpanminus
1. Get RT and extract to /tmp.
* wget https://download.bestpractical.com/pub/rt/release/rt-4.4.1.tar.gz * tar xvzf rt-4.4.1.tar.gz -C /tmp * cd /tmp/rt-4.4.1
1. Configure RT:
* ./configure --enable-graphviz --enable-gd --with-web-user=apache --with-web-group=apache
1. Configure RT to use cpanm for fixdeps:
* export RT_FIX_DEPS_CMD=/usr/local/bin/cpanm
1. Test the dependencies:
* make testdeps
1. Fix the dependencies:
* make fixdeps
* NOTE: You may need to run the command more than once. On RHEL 6.8, you may need to manually force the addition of the GD perl module via “cpanm GD --force”
1. Confirm the dependencies are complete:
* make testdeps
1. Install RT (default install is to the /opt/rt4 directory):
* make install
1. Modify /etc/httpd/conf.d/fcgid.conf. Add:
* FcgidMaxRequestLen 1073741824
1. Create /etc/httpd/conf.d/rt.conf:
- RT4 configuration for Apache
- Optional apache logs for RT
- Ensure that your log rotation scripts know about these files
- ErrorLog /opt/rt4/var/log/apache2.error
- TransferLog /opt/rt4/var/log/apache2.access
- LogLevel debug
