Hello,

Hello,
I installed Centreon on CentOS 5 and everything went well during the installation with the command line and the graphic installation, but when I type http://localhost/centreon/ in my browser, it displays a blank page. I also tried version 2.1.13 and I still have the same problem. What should I do?
Please help me, I am a beginner.

Configuration: Windows XP / Firefox 3.5.1

I suppose you are using an Apache web server to provide the Centreon page?

Which distribution are you using?

Have you configured a virtual host for Centreon?

If all this means little to you and you are using a Debian-based distribution (Ubuntu...), you can already start by reading this:

Good luck

thank you mamiemando for your help,
I'm using Centos5 and my apache server is installed and working correctly since I can access the nagios web interface just fine.
regarding the configuration of the virtual host for centreon, I don't know how to configure that since the tutorial I followed did not mention it.
thank you for helping me.

Hello,

a Centreon wiki is available: http://fr.doc.centreon.com/Setup/en

Moreover, a new project called CES allows the installation of Centreon from RPM: http://www.centreon.com/en/Centreon-Enterprise-Server/ces-downloads.html

If you want to install Centreon from source, I recommend using a more up-to-date version 2.3.3 and following the procedure from the wiki.

I have one of my former students who started making a script with an archive that installed everything, but I don't know where he is at since then. Maybe this will help you:

Hello,

A reflex to have when facing a blank page: check the error_log of Apache. It could be PHP errors (which don't display on the page if the Display_Errors flag is set to Off in php.ini). Or the files might not be accessible for reading for the account under which Apache is running.

Also, make sure your Apache is properly configured to redirect the URL /centreon to your directory <install_centreon>/www.

Edit: does your problem occur before or after the end of the installation in web mode?

Another idea that comes to mind is whether PHP is (correctly) installed on your Apache server. You should also check the Apache logs (/var/log/httpd/... or /var/log/apache2...)

Good luck

You can simplify your life by using Overmon

Overmon is a comprehensive asset management solution that includes a multitude of features such as: automatic inventory, monitoring, incident management, and many more.

Overmon is distributed under the GPLv2 license, and in the form of two components:

Overmon Server: A VMware appliance (Debian base) that includes the following tools:

. Nagios: Monitoring
. Centreon: Advanced front-end for Nagios
. Fusion Inventory: Automatic inventory
. Nagvis: Mapping
. GLPI: Asset management
. Mediawiki: Document management

Overmon Admin Tools: A complement to Overmon Server, this administration tool allows for:

. easy administration of the solution
. simplified deployment of monitoring and inventory agents.
. easy setup of monitoring for your Oracle, SQL Server, and MySQL databases
. assistance in developing new Nagios probes
. the ability to monitor websites, including authentication and functional navigation

In addition to the fact that Overmon Server provides a complete and functional installation of all these components out of the box, it also offers relevant integration between each of them.

For example: depending on your preferences, certain alarms occurring in Centreon can automatically trigger the creation of a ticket in GLPI.
