Upgrading Centreon to version 2.3.9

Centreon latest stable version was released on the 1st of August. On a server running RHEL 5.8 with the official Centreon repositories, here are the steps to follow. Make sure that you have installed the yum configuration file for CES repository :

root@localhost:~# cat /etc/yum.repos.d/ces-standard.repo

[ces-standard]
name=Centreon Entreprise Server RPM repository for ces $releasever
baseurl=http://yum.centreon.com/standard/stable/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CES
priority=1

[ces-standard-noarch]
name=Centreon Entreprise Server RPM repository for ces $releasever
baseurl=http://yum.centreon.com/standard/stable/noarch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CES
priority=1

[ces-standard-deps]
name=Centreon Entreprise Server dependencies RPM repository for ces $releasever
baseurl=http://yum.centreon.com/standard/stable/dependencies/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CES
priority=1

[ces-standard-deps-noarch]
name=Centreon Entreprise Server dependencies RPM repository for ces $releasever
baseurl=http://yum.centreon.com/standard/stable/dependencies/noarch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CES
priority=1
