Aujourd'hui je me suis amusé a tester Nagios puis Centreon. L'installation de Nagios s'est passé niquel depuis les ports. J'ai juste eu a reconfigurer les sample de /usr/local/etc/nagios en .cfg et a modifier Apache en mettant dans le httpd.conf 

<Directory /usr/local/www/nagios>
     Order deny,allow
     Deny from all
     Allow from 127.0.0.1
</Directory>

 <Directory /usr/local/www/nagios/cgi-bin>
     AllowOverride AuthConfig
     Options ExecCGI
   </Directory>

   ScriptAlias /nagios/cgi-bin/ /usr/local/www/nagios/cgi-bin/
   Alias /nagios/ /usr/local/www/nagios/
On crée ensuite le .htaccess et le .htpasswd dans /usr/local/www/nagios/cgi-bin/ et ca roule.

Pour Centreon, c'est une autre histoire vu qu'il n'est pas dans les ports :)

Donc j'ai commencé par télécharger la version 1.4.26 depuis le site de Centreon. J'ai bien sur lu le INSTALL et installé tous les packages nécessaires. Ensuite j'ai exécuté le fichier d'install : 
./install.sh
La commence la série de questions de Centreon ou j'ai du donner quelques coup de find et whereis pour voir ou étaient mes fichiers. Voila l'install :

Voila l'installation est maintenant terminée.

On va modifier notre httpd.conf pour pouvoir lancer Centreon : 
Alias /centreon/ /usr/local/centreon/www/
<Directory /usr/local/centreon/www/>
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
</Directory>

Je donne les droits nécessaires pour finir l'installation : 
chown -R www:nagios /usr/local/etc/nagios/
chown -R www:nagios /usr/local/libexec/nagios
chmod -R 775 /usr/local/libexec/nagios
chmod -R 775 /usr/local/etc/nagios/
chmod -R 775 /usr/local/centreon/ODS/
chown -R www:www /usr/local/centreon/ODS
chown -R www:www /usr/local/centreon/www
chmod -R 775 /usr/local/centreon/www

Je vais avoir besoin de packages PEAR donc je les installe direct avec la commande : 
pear install -o -f --alldeps DB DB_DataObject DB_DataObject_FormBuilder 
MDB2 Date Numbers_Roman Numbers_Words HTML_Common HTML_QuickForm
HTML_QuickForm_advmultiselect HTML_Table Auth_SASL HTTP Image_Canvas 
Image_Color Image_Graph Image_GraphViz Mail Mail_Mime Net_SMTP Net_Socket 
Net_Traceroute
Net_Ping Validate XML_RPC SOAP

Hop une fois tout cela fini on va sur la page http://127.0.0.1/centreon/ pour finir l'installation. La on donne les bons chemins, utilisateurs MySQL, pas besoin de faire un cours la dessus

Une fois tout cela terminé, il ne reste plus qu'a retourner sur http://127.0.0.1/centreon/ et a se logger.

Chanceux comme je suis ca n'a pas marché donc je me suis ajouté un utilisateur a la main.
Pour cela il faut aller dans la base centreon et dans la table contact. On ajoute un utilisateur avec un login, un alias (c'est lui qui sert de login), un mot de pass encrypté en MD5, et on met tout ce dont on a besoin a 1 (admin, enabled...)

On retente de se logger... Perso ca a encore foiré ... J'ai eu un DB insufficient permission.

On ne s'enerve pas et on va verifier les login et mot de pass dans les fichiers de conf :
- /usr/local/centreon/ODS/etc/conf.pm
- /usr/local/centreon/www/oreon.conf.php

La on met les bon logins et mot de pass mysql :)

Ouf ouf, on relance tout ca et miracle on arrive a se logger !

Maintenant il faut utiliser cet engin.

On commence par aller dans host, on ajoute un host, puis dans Service on ajoute ce que l'on veut exécuter comme commande et sur quel host.
Une fois cela fait, on va dans configuration > nagios > exporter, on coche tout les case du bas (4) et on choisi de restart Nagios. Perso il faut souvent que je restart a la main pour que ca marche vraiment. Et hopla tout marche par miracle :D

Allez bon courage a vous et j'espere que cela aidera du monde.
