nagiosweb permet de configurer nagios via une extention
du CGI de nagios. Il est donc intégré à l'interface Nagios.

Installation:

dload: http://sourceforge.net/projects/nagiosweb/

# tar zxf nagiosweb2-2.3.tar.gz
# cd nagiosweb
# chmod -R apache:apache nagiosweb
# cp -a nagiosweb /var/www/html
# cp images/prop.gif /usr/share/nagios/images/logos
# vi /etc/nagios/nagios.cfg
> cfg_file=/etc/nagios/hostextinfo.cfg
ou, pour la version 1.x
# vi /etc/nagios/cgi.cfg
> xedtemplate_config_file=/etc/nagios/hostextinfo.cfg
# mysql -u root
> create database nagiosweb;
...
> grant all on nagiosweb.* to nagiosweb@loclahost identified by 'nagiosweb';
...
> flush privileges;
> quit
# mysql -u nagiosweb -p nagiosweb < ~/nagiosweb/nagiosweb.sql
passwd: nagiosweb
#
# cd /var/www/html/nagiosweb
# vi dbconfig.php
> $db = ... user nagiosweb:nagiosweb
> $prefix = '/usr/lib/nagios';
> $etcprefix = '/etc/nagios';
> $htdocsdir='/var/www/html';
> $phppath='/usr/bin/php';
> $nagioshostname='localhost';
> $adminname='Benoit';
> $adminphone='+33000000000';
> $adminemail='root@localhost';

Donner le droit d'ecriture de la conf a apache:
# mkdir /etc/nagios-orig
# cp -a /etc/nagios/*.cfg /etc/nagios-orig
# chown -R apache /etc/nagios

Editer la barre de menu de Nagios:
# vi /usr/share/nagios/side.html
ajouter dans la partie configuration de la barre de navigation:
#<table width="150" border="0" cellpadding=0 cellspacing=0>
#  <tr>
#    <td width=13><img src="images/greendot.gif" 
#        width="13" height="14"
#        name="config-dot">

#     <td nowrap width=134><a href="/nagios/cgi-bin/config.cgi"

#        onMouseOut="switchdot('config-dot',0)"

Attention:
nagiosweb ne fonctionne que si la config nagios a les fichiers suivants:
checkcommands.cfg
hostgroups.cfg
hosts.cfg
servicegroups.cfg
services.cfg
contactgroups.cfg
contacts.cfg
escalations.cfg
timeperiods.cfg
... En effet, nagiosweb ne modifie pas nagios.cfg 
donc nagios.cfg doit inclure ces fichiers 'standards'

bon, j'ai pas le temps de bien tester. je m'en tape : nagios c'est de la *****.
nagiosweb ne semble pas *lire* la conf nagios
donc on ne peut que synchroniser dan un seul sens.

remarque: il manque le [service|host]extinfo.cfg dans le tarball de nagiosweb.
