[Linux] Installation serveur OCS-Inventory

 

Installation d’OCS-Inventory sur Centos

 

Version de l’OS: 6.8
Version de OCS: 2.3.1

 

Pré-requis
Un serveur LAMP opérationnel

Voir l’aricle pour activer / désactiver plusieurs vhost sur Centos

Le serveur Ocs sera sur la même vm que le serveur Glp.

 

 

Commençons par installer quelques paquets utiles.

$ sudo yum install vim git wget

 

Il faut ensuite installer perl et ces dépendances

$ sudo yum install perl-XML-Simple perl-Compress-Zlib perl-DBI perl-DBD-MYSQL perl-Net-IP perl-XML-Entities perl-Apache-DBI perl-Apache2-SOAP perl-SOAP-Lite perl-Archive-Zip mod_perl

 

Récupérer le dépôt ocs via git et plaçons le répertoire sur /opt

$ sudo git clone https://github.com/OCSInventory-NG/OCSInventory-ocsreports.git /opt/ocs
Initialized empty Git repository in /opt/ocs/.git/

Resolving deltas: 100% (15332/15332), done.

 

Créer une db et un user mysql
/!\ Mysql est déjà installé pour glpi.

$ mysql -u root -p
mysql> CREATE DATABASE ocs_db COLLATE UTF8_general_ci;

mysql> CREATE USER ocs_admin identified by 'mot_de_passe';

mysql> GRANT ALL PRIVILEGES ON ocs_db.* to ocs_admin@localhost identified by 'mot_de_passe';
mysql> quit

 

Éditer le fichier php.ini et corriger les valeurs ci dessous par celle affiché

$ sudo vim /etc/php.ini
php_value post_max_size         201m
php_value upload_max_filesize   200m

 

Créer les répertoires sites-available et sites-enabled

$ cd /etc/httpd/
$ sudo mkdir sites-available sites-enabled

 

puis ajouter la directive include au fichier httpd.conf

$ vim conf/httpd.conf
# Load config files from the config directory "/etc/httpd/conf.d".

Include sites-enabled/*.conf

 

De-commenter la directive NameVirtualHost dans le fichier httpd.conf

$ sudo vim /etc/httpd/conf/httpd.conf
NameVirtualHost *:80

 

Créer les vhosts dans le répertoire sites-available

$ sudo vim /etc/httpd/sites-available/glpi.domaine.tld.conf
<VirtualHost *:80>
ServerName glpi.domain.tld
DocumentRoot "/opt/glpi"
</VirtualHost>

 

$ sudo vim /etc/httpd/sites-available/ocs.domaine.tld.conf
<VirtualHost *:80>
ServerName ocs.domain.tld
DocumentRoot "/opt/ocs"
</VirtualHost>

 

Pour lister les vhosts, utiliser la commande apachectl

$ apachectl -S

 

Changer le propriétaire d’ocs

$ sudo chown -R apache:apache /opt/ocs

 

Reste plus qu’a redemarrer les services apache et mysql

$ sudo service restart httpd
$ sudo service restart mysqld

 

Connecter vous ensuite sur http://ocs.domaine.tld et renseigner les informations mysql

 

Le compte par défaut est admin / admin

 

/!\ Penser a supprimer le fichier install.php

$ sudo rm /opt/ocs/install.php

 

 


 

/!\ Ancienne version par Wget datant du 18 octobre 2016

Le serveur GLPI étant mis en place précédemment, je vais installer l’instance d’OCS sur la même VM, je récupère ainsi les services LAMP.

 

Il faut Installer Perl et ces dépendances

$ sudo yum install perl-XML-Simple perl-Compress-Zlib perl-DBI perl-DBD-MYSQL perl-Net-IP perl-XML-Entities perl-Apache-DBI perl-Apache2-SOAP perl-SOAP-Lite perl-Archive-Zip mod_perl

 

Télécharger la source d’OCS-Inventory serveur

$ wget https://github.com/OCSInventory-NG/OCSInventory-ocsreports/releases/download/2.2.1/OCSNG_UNIX_SERVER-2.2.1.tar.gz

 

Dé-zipper

$ tar xzf OCSNG_UNIX_SERVER-2.2.1.tar.gz

 

Lancer le setup.sh
L’installation se fait par défaut a l’exception de 2 points,
l’installation du paquet mod_perl demandera dans la configuration d’OCS de confirmer la version.

L’autre point porte sur le module Apache2::SOAP qui dit qu’il n’est pas installé. continuer ceci n’est pas bloquant, voir faq plus bas pour explications

DON'T FORGET TO RESTART APACHE DAEMON !

Enjoy OCS Inventory NG ;-)

 

Comme indiqué plus haut le vhost est crée dans /etc/httpd/conf.d/ocsinventory-reports.conf

Pour se connecter a Ocs il faut simplement ouvrir un navigateur et taper http://server//ocsreports. dans mon cas http://glpi.domaine.tld/ocsreports

ocs1

 

Il me manque le paquet php-soap, et des droits sur le répertoire ocsreports
pour rappel ma version de PHP est 5.6, voici donc le paquet a installer puis redémarrer apache

$ sudo yum install php56u-soap-5.6.27-1.ius.centos6.x86_64
$ sudo chown -R apache:apache /usr/share/ocsinventory-reports/ocsreports/
$ sudo service httpd restart

ocs2

 

Il faut fixer les limites minimum des variables post_max_size et upload_max_size
Éditer le vhost ocsinventory-reports.conf et le fichier php.ini

$ sudo vim /etc/httpd/conf.d/ocsinventory-reports.conf
$ sudo vim /etc/php.ini

Modifier les champs

php_value post_max_size         101m
php_value upload_max_filesize   100m

par

php_value post_max_size         201m
php_value upload_max_filesize   200m

 

Il faut maintenant créer db/user Mysql pour OCS.
Pour rappel, OCS et installé sur mon serveur GLPI, du coup mysql tourne deja avec un couple db/user pour glpi.

$ mysql -u root -p
CREATE DATABASE ocs_db COLLATE UTF8_general_ci;

CREATE USER 'ocs_admin' identified by 'mot_de_passe';

GRANT ALL PRIVILEGES ON ocs_db.* to 'ocs_admin'@localhost identified by 'mot_de_passe';

 

Si on change la db et le user mysql d’OCS, il faut le remplacer dans le fichier z-ocsinventory-server.conf
“WARNING: If you change default database name (ocsweb) or user (ocs), don’t forget to update the file ‘z-ocsinventory-server.conf’ in your Apache configuration directory”

$ sudo vim /etc/httpd/conf.d/z-ocsinventory-server.conf
# Which version of mod_perl we are using
# For mod_perl <= 1.999_21, replace 2 by 1 # For mod_perl > 1.999_21, replace 2 by 2
PerlSetEnv OCS_MODPERL_VERSION 2

# Master Database settings
# Replace localhost by hostname or ip of MySQL server for WRITE
PerlSetEnv OCS_DB_HOST localhost
# Replace 3306 by port where running MySQL server, generally 3306
PerlSetEnv OCS_DB_PORT 3306
# Name of database
PerlSetEnv OCS_DB_NAME ocsweb  <-- db name a changer
PerlSetEnv OCS_DB_LOCAL locahost  
# User allowed to connect to database
PerlSetEnv OCS_DB_USER ocs  <-- utilisateur a changer
# Password for user
PerlSetVar OCS_DB_PWD ocs  <-- password a changer

FAQ
** Warning: PERL module Apache2::SOAP is not installed !
This module is only required by OCS Inventory NG SOAP Web Service.

le module est bien installé mais impossible de zapper cette erreur.
j’ai cherché sur des forums, j’ai même usé de la commande cpan qui me dit que j’ai bien la version 0.73 … c’est une échec ! 😀

Ceci dit la majorité des réponses lus indique le Ce module n’est nécessaire que si il est prévu de requête le serveur OCS via SOAP. Si ce n’est pas le cas l’absence du module générera un message d’erreur dans le fichier error_log d’apache, seulement au démarrage d’apache.
