Update centreon 2.0.X to centreon 2.1.X

[INFO] If you have already installed centreon 2.1.X, go to next section

First, you need to remove centreon 2.0.2 and packs language :

# /etc/init.d/nagios stop
# /etc/init.d/ndo2db stop
# /etc/init.d/centcore stop
# /etc/init.d/centstorage stop
# yum remove centreon  centreon-2.0-de_DE centreon-2.0-nl_NL  centreon-2.0-es_ES  centreon-2.0-fr_FR centreon-2.0-no_NO centreon-2.0-ru_RU  centreon-database centreon-plugins centreon-2.0-es_PR centreon-2.0-pt_BR

Now, you can install centreon 2.1 :

# yum --disablerepo=* --enablerepo=base --enablerepo=updates --enablerepo=FAN install php-xml centreon-core centreon-database centreon-plugins centreon-storage centreon-trap centreon-www
# /etc/init.d/ndo2db start
# /etc/init.d/nagios start

Now, connect to interface Centreon and follow the steps to update the database. Go to http://FAN-SERVER/centreon/

Full update

Run a full update

# yum --disablerepo=* --enablerepo=base --enablerepo=updates --enablerepo=FAN --enablerepo=Graphviz update

If needed, connect to interface Centreon and follow the steps to update the database. Go to http://FAN-SERVER/centreon/

Update Nagvis 1.5.X

Download update-nagvis-1.4-to-1.5.sh script.

# wget https://fannagioscd.svn.sourceforge.net/svnroot/fannagioscd/tag/fannagioscd-2.1/extensions/update-nagvis-1.4-to-1.5.sh
# chmod +x update-nagvis-1.4-to-1.5.sh
# ./update-nagvis-1.4-to-1.5.sh

Finally, reboot the server

# reboot


If you encounter problems in reporting Centreon, run the following commands to regenerate.

# su - nagios -c "/usr/share/centreon/bin/logAnalyser -a"
# su - nagios -c "/usr/share/centreon/cron/archiveDayLog -r" 

If you lose your rrd graph in Views interface, there’re 2 options :

  • First solution
Clear the cache of your browser.
  • Second solution

During the update, it’s possible the directory /var/lib/centreon be deleted. You just recreate it :

# mkdir -p /var/lib/centreon
# chown -R nagios:nagios /var/lib/centreon

In Centreon, go to Administration -> CentStorage -> Manage
Select all data and do Rebuild RRD Database
So all rrd file will be generated in Views and wait few minutes (between 15 and 90 min) by centstorage daemon.
