Nagios3 Centreon2 Ubuntu centreon
From Wiki Centreon
downloading centreon
For downloading centreon you have two options. The most common is to download the archive from the centreon site but at the moment the version is in beta state. So it is recommended to get the version from SVN as it contains important changes and bugfixes.
- download the archive
# cd /usr/local/src/ # wget http://download.centreon.com/index.php?id=89
Unpack the archive and change the directory:
# tar -xzf centreon-2.0-RC3.tar.gz # cd centreon-2.0-RC3
or
- creating from SVN
# svn co http://svn.centreon.com/trunk/tools # cd tools # dos2unix makePackage.sh # chmod +x makePackage.sh
prior to execution the first line of the script should be changed to #! /bin/bash.
# ./makePackage.sh # cd centreon-2.0-SVN
Installation of Centreon
Before continuing a way to avoid different paths to binaries like nagios, ndomod etc.
# export PATH="$PATH:/usr/local/nagios/bin/"
Now the installation script is called. In this script you will be asked a number of questions which pertain the extent of the installation, different dependencies etc... In between you will find some comments on questions which are asked during the script.
# ./install.sh -i
first step: checking prerequisites

Now some questions regarding the modules to be installed: Centreon web interface, centcore (distributing module), Centreon plugins and Centreon Trap-Handler.
ATTENTION: using Centreon 2.0 beta 1 you cannot install centcore and centreon trap handler even if you respond with "y".
------------------------------------------------------------------------
Please choose what do you want to install
------------------------------------------------------------------------
Do you want to install Centreon Web Front
[y/n], default to [n]:
> y
Do you want to install Centreon CentCore
[y/n], default to [n]:
> n
Do you want to install Centreon Nagios Plugins
[y/n], default to [n]:
> y
Do you want to install Centreon Snmp Traps process
[y/n], default to [n]:

Now the installation of the different modules begins, starting with Centreon Web, the centreon interface.
------------------------------------------------------------------------
Start CentWeb Installation
------------------------------------------------------------------------
Where is your Centreon directory?
default to [/usr/local/centreon]
>
Where should centreon be installed? <Enter> accepts the shown default value. You can specify another path. If the directory doesn't exist you are asked if it should be created:
Do you want me to create this directory ? [/usr/local/centreon] [y/n], default to [n]: > y Path /usr/local/centreon OK
Here you should specify where to put the centreon journals/logs.
Where is your Centreon log directory default to [/usr/local/centreon/log/] > Do you want me to create this directory ? [/usr/local/centreon/log/] [y/n], default to [n]: > y Path /usr/local/centreon/log/ OK
very important : the location of centreon config file.\\ ATTENTION: changing the path may result in problems...
Where is your Centreon etc directory default to [/etc/centreon] > Do you want me to create this directory ? [/etc/centreon] [y/n], default to [n]: > y Path /etc/centreon OK
Where is your Centreon generation_files directory? default to [/usr/local/centreon/] > Path /usr/local/centreon/ OK
The path to RRDs.pm used by centstorage and centreon plugins.
Where is installed RRD perl modules [RRDs.pm] default to [/usr/lib/perl5/RRDs.pm] >/usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/RRDs.pm Path /usr/lib/perl5 OK /usr/bin/rrdtool OK /usr/bin/mail OK
Location of PEAR.php.
Where is PEAR [PEAR.php] default to [/usr/share/php/PEAR.php] >/usr/share/pear/PEAR.php Path /usr/share/php OK
Following a number of questions which try to locate different parts of Nagios.
Where is installed Nagios ? default to [/usr/local/nagios/] > Path /usr/local/nagios/ OK Where is your nagios config file default to [/usr/local/nagios/etc//nagios.cfg] > Path /usr/local/nagios/etc OK Where is your Nagios var directory ? default to [/usr/local/nagios/var/] > Path /usr/local/nagios/var/ OK Where is your Nagios plugins (libexec) directory ? default to [/usr/local/nagios/libexec/] > Path /usr/local/nagios/libexec/ OK Where is your nagios binary ? default to [/usr/local/nagios/bin/nagios] > /usr/local/nagios/bin/nagios OK Where is your Nagios image directory ? default to [/usr/local/nagios/share/images/logos/] > Path /usr/local/nagios/share/images/logos/ OK Where is your nagiostats binany ? default to [/usr/local/nagios/bin/nagiostats] > /usr/local/nagios/bin/nagiostats OK p1_file : /usr/local/nagios/bin/p1.pl OK /usr/bin/php OK Finding Apache group : www-data Finding Apache user : www-data Finding Nagios user : nagios Finding nagios user nagios in /etc/passwd OK Finding Nagios group : nagios Finding nagios group 'nagios' in /etc/group OK
ATTENTION: the name of user and group of the web server depends from the used distribution!
Now the script asks if you want to use NDO. You better confirm it because otherwise you can't use the benefit of some improvements: AJAX, monitoring performance, etc. (Note: despite deselection you will get messages that NDO access to the database fails).
Do you want use NDO ? [y/n], default to [n]: > y
The script asks for the location of the NDO modules. The path is important for a working connection to NDO.
Where is your NDO ndomod binary ? default to [/usr/sbin/ndomod.o] > /usr/local/nagios/bin/ndomod-3x.o /usr/local/nagios/bin/ndomod-3x.o OK
Now sudo will be configured to grant permissions to centreon for specific changes (e.g. restart of Nagios)
------------------------------------------------------------------------
Configure Sudo
------------------------------------------------------------------------
Where is sudo configuration file
default to [/etc/sudoers]
>
/etc/sudoers OK
Nagios init script OK
Your sudo is not configure
Do you want I configure your sudo ? (WARNING)
[y/n], default to [n]:

Now some questions regarding the configuration of the apache web server.\\ This beta version will not accept the httpd scripts on Fedora so you have to restart the web server manually after the end of the installation!
------------------------------------------------------------------------
Configure Apache server

Attention: the centreon lib directory should be placed on a continously available partition to avoid problems. The directory contains the RRDTools. Consider to place the MySQl data on a reasonably dimensioned disk. The logs and performance data also need a lot of space.
