Installation and Configuration of a Centreon Server
Introduction
Centreon is one of the most flexible and powerful GPL-licensed monitoring software solutions. It’s built on top of the OpenSource Nagios technology.
Designed for a wide range of users, it’s perfectly suited for measuring system, network, and application indicators. Centreon brings together essential functions for managing monitoring of critical infrastructures. Being modular, it adapts to your needs and allows you to extend its functionality further.
For my part, I chose to move from Nagios 3 to Centreon to get graphics and reporting capabilities.
The installation below is performed on Debian Lenny 64 bits.
Installation
LAMP
For the installation, we’ll first install the prerequisites, namely a web server, mail server, and SQL (Apache2+PHP, postfix, mysql) as well as the necessary libraries to create graphs (rrdtool):
aptitude install sudo sysutils mailx lsb-release postfix build-essential apache2 apache2-mpm-prefork php5 php5-mysql php-pear php5-ldap php5-snmp php5-gd mysql-server-5.0 libmysqlclient15-dev rrdtool \
librrds-perl libconfig-inifiles-perl libcrypt-des-perl libdigest-hmac-perl libdigest-sha1-perl libgd-gd2-perl snmp snmpd libnet-snmp-perl libsnmp-perl libgd2-xpm libgd2-xpm-dev libpng12-dev
Nagios 3
Next, we’ll install nagios3 and the plugins:
aptitude install nagios3 nagios3-common nagios3-doc nagios-plugins nagios-plugins-basic nagios-plugins-standard nagios-images dnsutils fping
Let’s create the nagcmd group, then add nagios and nagcmd to www-data (apache2):
groupadd nagcmd
usermod -G nagios,nagcmd nagios
usermod -G nagios,nagcmd www-data
NDOutils
Let’s install NDOutils:
aptitude install ndoutils-nagios3-mysql ndoutils-common dbconfig-common
Let’s activate it by setting the following value to 1:
ENABLE_NDOUTILS=1
Then restart the service:
/etc/init.d/ndoutils restart
Centreon
Finally, we arrive at Centreon! Let’s download the latest version, decompress it, then start the installation:
cd ~
wget "http://download.centreon.com/index.php?id=105"
tar -xzf centreon-2.0.2.tar.gz
cd centreon-2.0.2
./install.sh -i
And that’s it… the installation has started!!! So, here are the steps one by one (we’ll follow the method step by step in case you have differences):

q
Do you accept GPL license?
[y/n], default to [n]:
Enter y.
------------------------------------------------------------------------
Please choose what you want to install
------------------------------------------------------------------------
Do you want to install: Centreon Web Front
[y/n], default to [n]:
Well, the frontend is important, it’s actually the main reason we’re installing it:
------------------------------------------------------------------------
Please choose what you want to install
------------------------------------------------------------------------
Do you want to install: Centreon Web Front
[y/n], default to [n]:
So enter y.
Do you want to install: Centreon CentCore
[y/n], default to [n]:
For my part, I’ll say yes (y). But you should decide based on your needs. CentCore allows you to have satellites in datacenters or branches, for example, to avoid false alerts in case of line loss between your server and agents (like NRPE or NCSA).
To summarize, if you’re going to deploy a large architecture, I recommend it; otherwise, leave it as no.
Next for Nagios plugins, of course we’ll install them:
Do you want to install: Centreon Nagios Plugins
[y/n], default to [n]:
So enter y.
Do you want to install: Centreon Snmp Traps process
[y/n], default to [n]:
Again, if you need to receive SNMP traps from your equipment (like Cisco, Alcatel, Brocade, etc.), then activate this; otherwise, it’s not necessary. For me, I need it so I enter y.
Where is your Centreon directory?
default to [/usr/local/centreon]
Do you want me to create this directory? [/usr/local/centreon]
[y/n], default to [n]:
If the folder suits you, enter y; otherwise, create it and modify the path. I’ll keep it (so y).
Path /usr/local/centreon OK
Where is your Centreon log directory
default to [/usr/local/centreon/log]
Now, let’s create a proper log directory at /var/log/centreon:
> /var/log/centreon
Do you want me to create this directory? [/var/log/centreon]
[y/n], default to [n]:
> y
Path /var/log/centreon OK
Now, the configuration files. The default location is just fine:
Where is your Centreon etc directory
default to [/etc/centreon]
That’s perfect, so press ’enter'.
Do you want me to create this directory? [/etc/centreon]
[y/n], default to [n]:
> y
Path /etc/centreon OK
And yes, it will create it (y).
PS: If you’re getting tired, you can take a break; it’s still a bit long.
Where is your Centreon generation_files directory?
default to [/usr/local/centreon]
Path /usr/local/centreon OK
This looks good to me (enter).
Where is your Centreon variable library directory?
default to [/var/lib/centreon]
>
Directory /var/lib/centreon does not exists. CRITICAL
Where is your Centreon variable library directory?
default to [/var/lib/centreon]
>
Do you want me to create this directory? [/var/lib/centreon]
[y/n], default to [n]:
> y
Path /var/lib/centreon OK
We validate again.
Where is the RRD perl module installed [RRDs.pm]
default to [/usr/lib/perl5/RRDs.pm]
Path /usr/lib/perl5 OK
/usr/bin/rrdtool OK
/usr/bin/mail OK
Great, the paths are correct, we validate. And for PEAR?
Where is PEAR [PEAR.php]
default to [/usr/share/php/PEAR.php]
Path /usr/share/php OK
Great, it’s correct again… we’re lucky! Shall we continue?
Where is installed Nagios?
default to [/usr/local/nagios]
This is wrong! Since we installed nagios via Debian repositories, not via source, the path is incorrect. The correct path is /usr/share/nagios3:
/usr/share/nagios3
Path /usr/share/nagios3 OK
Where is your nagios config directory
default to [/usr/local/nagios/etc]
Here we’ll enter /etc/nagios3:
Where is your nagios config directory
default to [/usr/local/nagios/etc]
/etc/nagios3
Path /etc/nagios3 OK
Let’s enter /var/log/nagios3 here, which will contain the nagios.log file:
Where is your Nagios var directory?
default to [/usr/local/nagios/var]
/var/log/nagios3
Path /var OK
The directory below is supposed to contain all the plugins. We’ll enter /usr/lib/nagios/plugins:
Where is your Nagios plugins (libexec) directory?
default to [/usr/local/nagios/libexec]
/usr/lib/nagios/plugins
Path /lib OK
/usr/sbin/nagios3 OK
Now, the location of the logos that we’ll change to /usr/share/nagios3/htdocs/images/logos:
Where is your Nagios image directory?
default to [/usr/local/nagios/share/images/logos]
/usr/share/nagios3/htdocs/images/logos
Path /usr/share/nagios3/htdocs/images/logos OK
/usr/sbin/nagios3stats OK
p1_file: /usr/lib/nagios3/p1.pl OK
/usr/bin/php OK
/usr/bin/perl OK
For CentPlugins, we’ll leave everything at default and let it create the directory:
Where is your CentPlugins Traps binary
default to [/usr/local/centreon/bin]
Do you want me to create this directory? [/usr/local/centreon/bin]
[y/n], default to [n]:
Path /usr/local/centreon/bin OK
Finding Apache group: www-data
Finding Apache user: www-data
Finding Nagios user: nagios
Finding Nagios group: nagios
For the ndo library, it’s /usr/lib/ndoutils/ndomod-mysql-3x.o:
Where is your NDO ndomod binary?
default to [/usr/sbin/ndomod.o]
/usr/lib/ndoutils/ndomod-mysql-3x.o
/usr/lib/ndoutils/ndomod-mysql-3x.o OK
Now, for sudo configuration, everything is good by default, we don’t touch anything, it does everything automatically:
------------------------------------------------------------------------
Configure Sudo
------------------------------------------------------------------------
Where is sudo configuration file
default to [/etc/sudoers]
/etc/sudoers OK
Nagios init script OK
Your sudo is not configured
Do you want me to configure your sudo? (WARNING)
[y/n], default to [n]:
> y
Configuring Sudo OK
Now comes the time for Apache. It offers to make the configuration for us (great):
------------------------------------------------------------------------
Configure Apache server
------------------------------------------------------------------------
Do you want to add Centreon Apache sub configuration file?
[y/n], default to [n]:
So enter y, to reload the configuration and finally check the modules (y):
Do you want to reload your Apache?
[y/n], default to [n]:
Reloading Apache service OK

Done!!! We thought it would never end! If their script could do auto-detection, we would save time. And if it was packaged, it would be even better! But well, it’s their livelihood! It’s already free; we shouldn’t complain too much!
Let’s restart the Apache service and proceed:
/etc/init.d/apache2 restart
Configuration
Centreon
We can now move on to the graphical interface! First, let’s set the correct permissions on the nagios3 folder:
chown -Rf nagios:www-data /etc/nagios3
chmod -Rf 775 /etc/nagios3
Now, let’s connect to http://your-server/centreon and start the installation:
Everything should be good so far.
Adjust the values for your database.
Specify the user who will be the Centreon admin.
For my part, I chose to have my users connect via LDAP, so I configure my OpenLDAP parameters below.
All is good, the installation is complete :-)
Nagios
Now, let’s move on to configuration. Go to Configuration -> Nagios -> nagios.cfg and modify the following lines:
Log file: /var/log/nagios3/nagios.log
Downtime File: /var/cache/nagios3/downtime.log
Comment File: /var/cache/nagios3/comment.log
Temp File: /var/cache/nagios3/nagios.tmp
Lock File: /var/cache/nagios3/nagios.lock
Status File: /var/log/nagios3/status.log
External Command File: /var/lib/nagios3/rw/nagios.cmd
Go to Configuration -> Nagios -> nagios.cfg -> Data and modify the following lines:
Service Performance Data File: /usr/lib/nagios/plugins/process-service-perfdata
Go to Configuration -> Nagios -> cgi -> Cgi.cfg and modify the following lines:
URL HTML Path: /nagios3
Nagios Process Check Command: /usr/lib/nagios/plugins/check_nagios /var/log/nagios3/status.log 5 '/usr/sbin/nagios3'
Save and then run this command:
chown nagios. /usr/lib/nagios/plugins/process-service-perfdata
ndo2db
- First, let’s set the basic parameters. Take your beautiful graphical interface and go to: Configuration -> Centreon -> ndo2db.cfg -> Main, then modify this:
Socket Type: unix
Socket Name: /var/cache/nagios3/ndo.sock
- Now go to Configuration -> Centreon -> ndo2db.cfg -> Main -> Database and adapt it to your configuration. For my part, I had to change the following fields:
Database Name: ndoutils
User: ndoutils
Password: password
Set the password you want and save. Then do the same for this user at the SQL level:
mysql -uroot -p
SET PASSWORD FOR 'ndoutils'@'localhost' = PASSWORD('password');
FLUSH PRIVILEGES;
ndomod
Let’s go to Configuration -> Centreon -> ndo2db.cfg and modify these parameters:
Instance Name: default
Interface Type: unixsocket
Output: /var/cache/nagios3/ndo.sock
Buffer File: /var/cache/nagios3/ndomod.tmp
Then save and restart the service:
/etc/init.d/ndoutils restart
CentStorage
Now we need to configure CentStorage which will allow us to create beautiful graphs. To do this, go to Administration -> Options -> CentStorage -> Options, then modify the following:
Perfdata: /usr/lib/nagios/plugins/process-service-perfdata
Drop file: /var/lib/centreon/service-perfdata.tmp
Nagios current log file to parse: /var/log/nagios3/nagios.log
We’ll also set permissions on the logs directory, otherwise centstorage won’t be able to create its logs:
chown -Rf nagios. /var/log/centreon
Then let’s restart CentStorage:
/etc/init.d/centstorage restart
Languages
PhpSysInfo
For those who don’t know, PhpSysInfo is integrated into Centreon (they’re right, why reinvent the wheel). To make some nice tweaks, here’s the config file:
$default_template='aq';
$loadbar = true;
This gives us an aqua theme (like Mac OS X) and a system load bar, which is nice. You can also configure other info about disk temperature, etc… I invite you to check out the official documentation.
Enabling the Nagios Web Interface
We’ll enable this interface for 2 reasons:
- Basic file permissions
- Having a backup interface
Let’s create the file (unless it already exists) /etc/nagios3/htpasswd.users by directly adding a nagios user to it. For this, we’ll use the htpasswd command:
htpasswd -c /etc/nagios3/htpasswd.users nagiosadmin
Set a password. If you need to add other users, do the same without the “-c”, for example:
htpasswd /etc/nagios3/htpasswd.users deimos
Then reload your Apache config. Next, you’ll need to modify the Centreon configuration by going to Configuration -> Nagios -> cgi, and replacing nagiosadmin with the nagios user. Then reload your Nagios config from Centreon.
FAQ
Connection Error to NDO DataBase!
This is due to the packaged installation of Debian! It’s not much to fix.
Look above, the answer is there.
movement KO
If you have these types of errors when loading your Nagios config from Centreon, it’s either a permission problem or an NDOutils problem. Make sure you’ve followed the procedure described above.
Warning: File ‘/var/lib/centreon/service-perfdata’ could not be opened - service performance data will not be written to file!
If this happens in the nagios logs, don’t panic, just reset the permissions:
chown nagios. /var/lib/centreon/service-perfdata
Then restart nagios!
DB Error
You might have a message like this in the centAcl.log file:
DB Error: DELETE FROM `centreon_acl` WHERE `group_id` = '14' [nativecode=1146 ** Table 'ndoutils.centreon_acl' doesn't exist]
This means the ‘centreon_acl’ table is missing. Let’s create it:
mysql -uroot -p
use ndoutils;
CREATE TABLE IF NOT EXISTS `centreon_acl` (
`id` int(11) NOT NULL auto_increment,
`host_name` varchar(255) default NULL,
`service_description` varchar(255) default NULL,
`group_id` int(11) default NULL,
PRIMARY KEY (`id`),
KEY `host_name` (`host_name`),
KEY `service_description` (`service_description`),
KEY `group_id` (`group_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
quit;
I don’t have graphs, no errors
A small reboot would be good. I know we’re not on Windows, but there are so many services around Centreon that a small reboot would help all these services start correctly and reset certain things.
From Centreon my Nagios export works without errors, yet I don’t see my new services appearing
This is due to the CGI user not matching. It’s true that a test is missing here that could validate the permissions. In the meantime, it’s quite blocking; I advise you to check out enabling the Nagios web interface to solve your problem.
