centreon 24.04 web access stuck in centreon is loading

Hello,

I am trying to set up Centreon 24.04 on Debian 12. When I access the Centreon GUI, I encounter a loading issue. Checking the Apache2 logs reveals the following error:

[proxy_fcgi:error] [pid 29198] [client 192.168.1.33:61829] AH01071: Got error 'PHP message: PHP Fatal error: Uncaught RuntimeException: Unable to create the "cache" directory (/var/cache/centreon/symfony). in /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php:598 Stack trace: #0 /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php(505): Symfony\Component\HttpKernel\Kernel->buildContainer() #1 /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php(763): Symfony\Component\HttpKernel\Kernel->initializeContainer() #2 /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php(185): Symfony\Component\HttpKernel\Kernel->preBoot() #3 /usr/share/centreon/api/index.php(47): Symfony\Component\HttpKernel\Kernel->handle() #4 {main} thrown in /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php on line 598', referer: http://192.168.1.2/centreon/

Steps to Reproduce:

Install Centreon 24.04 on Debian 12.
Access the Centreon GUI via a web browser.
Observe the loading issue and check the Apache2 logs.

Additional Information:

OS: Debian 12
Centreon Version: 24.04
Apache Version: 2.4.59
PHP Version: 8.1.28
mariadb Version : 15.1 Distrib 10.11.6-MariaDB

Troubleshooting Steps Taken:

Verified that the /var/cache/centreon/symfony directory not exists.

Thank you

Resolve it by using this command :

sudo mkdir -p /var/cache/centreon/symfony && sudo chown www-data:www-data /var/cache/centreon/symfony

I had exactly the same thing on Debian 12, it's not normal that it’s not managed during installation!

More precisely, you must give the rights following

chmod 755 to the "centreon" folder in /var/cache/,

then after installing the centreon packets you must modify this folder again to put centreon as owner on this folder

chown centreon:centreon centreon

Hi we are solving this packaging issue.

Hello,

I have had the same issue since updating to version 24.10. However, I have followed your discussions closely and I have the same rights mentioned above. I have cleared the cache of the supervisor as well as the browser (Firefox or Chromium).

Hi @cedben12 are you talking about your browser cache because you put symphony cache screenshot of the Centreon central server?

Hi,

In fact, even after clearing the server cache, when I try to connect to the Centreon UI, the page displays “Centreon is loading.”

@cedben12 you need to clear your browser cache on your desktop too.

Hi,

I have a similar issue but the error am getting on php-fpm logs are below.

This happens when we try to update to 24.04.18 from 24.04.05
