RT 4.4.1 installation on CentOS 7.2.1511

NOTE: I'm tracking the formatting is out of control on this page. I'll be editing it to repair it. The text here is functional, I just need to work on the wiki markup formatting!


  • Access to the internet and CentOS OS and update repositories is available.
  • Installation testing was completed using CentOS 7.2.1511 minimal boot ISO.
  • httpd (Apache) 2.4 and mod_fcgid Apache modules were used as the host environment.
  • Testing was conducted in both KVM and vSphere environments.

Installation Steps

OS Installation and Initial Configuration

(!) It is possible to automate the majority of this section using kickstart files.

  1. Install OS. Install the OS from ISO or PXE boot using your normal methodology.
  1. 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 the OS.
  • If you are continuing to next step immediately, do not reboot.
  1. Disable selinux, by editing /etc/sysconfig/selinux:

  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.

Configure Supporting Software

  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. Configure RT to use cpanm for fixdeps:

export RT_FIX_DEPS_CMD=/usr/local/bin/cpanm

RT Dependencies and Installation

  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. 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

RT Configuration using Web Interface

(!) It is possible to complete this step by editing the RT files directly, and creating the database. Refer to the RT documentation for manual steps.

  1. Run the first run installation instance:

  • Access the server using a web browser on the http 80 port.
  1. Configure the rt instance using the web interface (fill this section in).
  1. When completed Ctrl-C the rt-server instance started above.

Configure RT for hostname.domain.name/rt directory

(!) This is a personal preference. The web server example below assumes /rt is used.

  1. Modify /opt/rt4/etc/RT_SiteConfig.pm. Add the following line:

Set( $WebPath, '/rt' );

Configure web server

  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

AddDefaultCharset UTF-8

Alias /rt/NoAuth/images /opt/rt4/share/html/NoAuth/images/

ScriptAlias /rt /opt/rt4/sbin/rt-server.fcgi/

DocumentRoot "/opt/rt4/share/html"

  # For Centos7/Apache 2.4 this line:
  Require all granted
  # For Centos6/Apache 2.2 these two lines:
  # Order allow,deny
  # Allow from all
  Options +ExecCGI
  AddHandler fcgid-script fcgi

  1. Start apache:

systemctl start httpd.service
  1. Modify firewalld configuration to suite your local requirements.

(!) NOTE: Depending on install method, firewalld may not be installed. You can also stop it for testing with the "systemctl stop firewalld" command.
