Installing Centreon 2.4 on CentOS 6.3 x64 - Step by Step

Scope

In this no-brainer guide I am going to detail how to install Centreon on a brand new CentOS 6.3 x64 machine.

Components:

• CentOS 6.3 x64 (this)
• Nagios Core 3.4.4 (this)
• Nagios Plugins 1.4.16 (this)
• Centreon 2.4 (this)

Prerequisites

• CentOS is installed in text-mode using the CentOS-6.3-x86_64-LiveCD.iso image on a VirtualBox VM in my case

• Firewall ports 22 and 80 have been opened by the configuration tool

• Default services have been installed + sshd
• I consciously don't start the with yum update/upgrade so the expected result should be as much the same as possible

# install RPMForge
# for details visit this website: http://wiki.centos.org/AdditionalResources/Repositories/RPMForge
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

uname -i
# for me 'x86_64' is the result so I'll choose the x86_64 version
wget -N http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
rpm -i rpmforge-release-0.5.2-2.el6.rf.*.rpm
