English : OCS and GLPI installation guide
This guide is designed for Fedora, RHEL and CentOS distributions which provides RPM of OCS and GLPI in their official repositories.
We consider the server is freshly installed : MySQL is not installed nor configured.
This article was writen with OCS version 1.02 RC3 and GLPI 0.71.2.
In this tutorial, I use rootsecret, ocssecret, glpisecret, syncsecret as password, of course, you should use other values…
The database server
MySQL installation, launch and activation :
# yum install mysql-server # service mysqld start # chkconfig mysqld on
Some security on the server : we must change the database administrator password, drop the test database, disable anonymous access, etc:
If you’ve completed all of the above steps, your MySQL installation should now be secure. (We will consider the root password is set to rootsecret)
OCS Inventory NG
# yum install ocsinventory # service httpd restart # chkconfig httpd on
Configuration and database schema creation :
Connect to http://localhost/ocsreports/install.php (must be modified if you are connected to the server from another computer).
Step 1 : enter the MySQL administrator login and password, then Send.
Step 2 : schema creation. If all is ok (must be true using the RPM), clic on Send
Step 3 : installation final step. write somewhere the account created (admin/admin) and clic on Click here to enter OCS-NG GUI.
Step 4 : choose your language (using the flag on the right top)
Step 5 : connect to the application (admin/admin)
Congratulations. You have OCS installed !
Some required configuration options : open the pipe wrench / Configuration / Config and then the Server tabs:
LOGLEVEL = On (really usefull when you encounter an issue)
PROLOG_FREQ = 24 (time between 2 inventory)
AUTO_DUPLICATE_LVL = crtieria used to detect that 2 computers are the same (I use Model + Serial + Mac Address).
TRACE_DELETED = On (required by GLPI).
SESSION_VALIDITY_TIME = 600 (session duration, the empty value provided is not valid).
Changing the application admin password is also really a good idea (don’t forget it) : use the “key” icon on the right top.
During the installation step a new database ocsweb is created and a MySQL account ocs with a default password = ocs, which is really not secure.
We need to change the MySQL password :
# mysql -uroot -prootsecret mysql> UPDATE mysql.user SET Password = PASSWORD(‘ocssecret’) WHERE User = ‘ocs’; mysql> FLUSH PRIVILEGES; mysql> exit
And to update the configuration file with this new password :
In the /etc/httpd/conf.d/ocsinventory-server.conf file (arround line 31) :
PerlSetVar OCS_DB_PWD ocssecret
In the /etc/ocsinventory/ocsinventory-reports/dbconfig.inc.php file :
Tell apache to reload his configuration for perl module to read the new parameter value:
# service httpd reload
To test the inventory feature, we are going to install the inventory agent on a first computer. Of course it will be on our server.
# yum install ocsinventory-agent
Now, send the inventory:
# ocsinventory-agent –server=localhost
If all is ok, your server should be in the computer list in OCS.
You can enable the automatic inventory of this computer, edit the /etc/sysconfig/ocsinventory-agent:
To start, we are going to create the database schema and the MySQL accounts for GLPI. Using the administrator (root) account is really a bad idea. The glpi account will be used by the application, and the synchro account for the synchronizaton process (to read the ocsweb database from glpi with only minimum rights).
N.B. in this example, the synchro user rights are reduce to the minimal. In the case you want to use some special plugins (uninstall p.e.), full right are required.
# mysql -uroot -prootsecret mysql> CREATE USER ‘glpi’@’%’ IDENTIFIED BY ‘glpisecret’; mysql> GRANT USAGE ON *.* TO ‘glpi’@’%’ IDENTIFIED BY ‘glpisecret’; mysql> CREATE DATABASE IF NOT EXISTS `glpi` ; mysql> GRANT ALL PRIVILEGES ON `glpi`.* TO ‘glpi’@’%’; mysql> CREATE USER ‘synchro’@’%’ IDENTIFIED BY ‘syncsecret’; mysql> GRANT USAGE ON *.* TO ‘synchro’@’%’ IDENTIFIED BY ‘syncsecret’; mysql> GRANT SELECT ON `ocsweb`.* TO ‘synchro’@’%’; mysql> GRANT DELETE ON `ocsweb`.`deleted_equiv` TO ‘synchro’@’%’; mysql> GRANT UPDATE (`CHECKSUM`) ON `ocsweb`.`hardware` TO ‘synchro’@’%’; mysql> FLUSH PRIVILEGES; mysql> exit
# yum install glpi # service httpd reload
Database schema creation and configuration
Connect to the application : http://localhost/glpi/ it will launch the configuration wizard.
select your language and : OK.
read and accept the license (GPL) : Continue
start the installation : Installation
step 0 : prerequisites check (must be ok with the RPM) : Continue
step 1 : enter the database connexion parameters (localhost / glpi / glpisecret) : Continue
step 2 : select the glpi database and Continue
step 3 : write somewhere the adminstrateur login and password (glpi/glpi) et Continue
step 4 : also write the other account informations : Use GLPI
Authentificate yourself with the new account : glpi/glpi
Congratulations (again) : you have GLPI installed !
OCSNG mode configuration
OCSNG mode activation :
Menu Setup / General
Activate OCSNG mode : Yes, and Post
Server Configuration :
Menu Setup / OCSNG mode
Select the server created during installation: localhost
Name: My OCS Server
OCSweb host: localhost
Name of the OCS database: ocsweb
OCSweb database user: synchro
OCSweb user password: syncsecret
You must get the Connection to OCS database successful message.
Now, we must configure the informations that will be imported from OCS to GLPI. Here is a few examples :
Monitors : Unit import on Serial number
Logiciels : Unit Import
Use the software dictionary of OCS: No
Number of computers to synchronize using the cron: 0 (we are going to use another solution)
General informations Computers : Yes for all that you are interested by.
Components : Yes for what you want.
etc, etc (you should notice that a lot of behavior are configurable)
Menu Tools / OCSNG
Import new computers
In the displayed list, you should see your server (on which we have installed the agent). Don’t ask for it to be imported as we are going to see how to use automatic synchronization.
Automatic OCSNG synchronization
This step is not required as the internal pseudo–cron integrated in GLPI also do an automatic synchronization. But this solution seems more cumfortable and flexible (at least, for me).
We are going to use the Mass import from OCSNG plugin.
Disconnect from GLPI (logout link) and install the plugin:
# yum install glpi-mass-ocs-import
Connect into GLPI to install / configure the plugin :
Menu Setup / Plugins
Link : OCS massive Import
Link : Install OCS massive import plugin (plugin tables creation)
Default OCS server: My OCS Server
Post the configuration page
Enable the synchronization
The planified task configured by the RPM will be launched every 5 minutes. Be patient, your first computer should be imported into GLPI.
Tu supervise the synchronization :
Menu : Plugins / OCS Massive Import
Tab : Informations about scripts execution
We have configured one of the best inventory and asset management solution in a few minutes (probably the best, as it is OpenSource)
You can now continue to deploy the inventory agent on your other computers, it’s available for most OS.
Take also some time to read the official documentation to be able to tune your configuration to fully suite your need:
Don’t forget than OpenSource projects exists thanks to their community and to their users contributions. So when you’ll have seen what OCS and GLPI can do for you, don’t forget to do something for this projects:
