Again, I just want to add more details about my issue :
1/ Same as this page https://forum.centreon.com/forum/centreon-collect/centreon-broker/152788-file-does-not-exist-usr-share-centreon-www :
My error_log file contains :
>Fri Feb 11 10:37:35.850065 2022] 2authz_core:error] opid 2211] 1client 10.1.239.165:24253] AH01630: client denied by server configuration: /usr/share/centreon/monitoring
In fact, this path really doesn’t exists :
# cd /usr/share/centreon/monitoring
-bash: cd: /usr/share/centreon/monitoring: No such file or directory
#
Sadly, this link had no answers.
2/ Also, like this other page https://github.com/centreon/centreon/issues/9177 :
My access_log file contains :
10.1.239.165 - - 211/Feb/2022:16:31:51 +0100] "GET /centreon/monitoring/resources HTTP/1.1" 404 - "http://172.17.160.77/centreon/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.80 Safari/537.36 Edg/98.0.1108.43"
and httpd returned :
# ./usr/sbin/httpd --help
httpd: Syntax error on line 56 of /opt/rh/httpd24/root/etc/httpd/conf/httpd.conf: Syntax error on line 40 of /opt/rh/httpd24/root/etc/httpd/conf.modules.d/00-base.conf: Cannot load modules/mod_http2.so into server: libnghttp2-httpd24.so.14: cannot open shared object file: No such file or directory
So, there is no http2 for me (this doesn’t seems to be a big issue...).
Alex.
Hello @amontaro
Can you share us your 10-centreon.conf file just to do a quick review?
And also, could you try to comment the line 40 in the file /opt/rh/httpd24/root/etc/httpd/conf.modules.d/00-base.conf just like this to test:
#LoadModule http2_module modules/mod_http2.so
And then try to restart again httpd24-httpd ?
First, thanks for your answer @Kriko !
Of course, I already tried that but again :
With “#LoadModule httpd...” commented in 00-base.conf and httpd24-httpd restarted I got the same error page but httpd now run without any complaints :
<root@xxx:/opt/rh/httpd24/root># ./usr/sbin/httpd --help

RewriteConditions and RewriteRules lines were already present in that file. I didn’t add them by myself. Also, notice that 404 error never reached /centreon/index.html file (it exists but is empty).

@Kriko : As I want to be sure that no files has disappears.
Please, can you confirm me that this directory is empty for you too ?
# ls -la /usr/share/centreon/monitoring
ls: cannot access /usr/share/centreon/monitoring: No such file or directory
#
Thanks,
Alex.
Alex,
Do not worry about this directory, it’s doesn’t exit at the root of centreon folder.
Could you try the following actions:
- Could you check if php-fpm is running which the commande:
systemctl status rh-php72-php-fpm
- Could you check to reset the apache root using the following command:
sudo -u apache /usr/share/centreon/bin/console cache:clear
And then try again?
-
Could send me the logs /var/opt/rh/rh-php72/log/php-fpm/centreon-error.log ?
Sure.
- PHP seems to be running fine :
# systemctl status rh-php72-php-fpm

#
- Step 2 seems to have clear something but I still got a 404 not found error page :
# sudo -u apache /usr/share/centreon/bin/console cache:clear
// Clearing the cache for the prod environment with debug false
sOK] Cache for the "prod" environment (debug=false) was successfully cleared.
#
- The logs you’re talking about is still empty and hasn’t been touched :
# more /var/opt/rh/rh-php72/log/php-fpm/centreon-error.log
# ls -la /var/opt/rh/rh-php72/log/php-fpm/centreon-error.log
-rwxrwxrwx 1 apache apache 0 Feb 12 03:36 /var/opt/rh/rh-php72/log/php-fpm/centreon-error.log
#
Remember that in issues/9177 page above, it was reported that no PHP errors appears in log files.
Perhaps are you interested by the previous centreon-error.log file ?

Alex.
Finally, the reason why my Centreon was not functionnal is because my /usr/share/centreon/www/index.html file was empty and everything works now fine with the content you gave me :
<!doctype html><html lang="en" style="margin:0;padding:0;width:100%;height:100%;"><head><meta charset="utf-8"><link rel="shortcut icon" href="./img/favicon.ico"><meta name="viewport" content="width=device-width,initial-scale=1,shrink-to-fit=no"><meta name="theme-color" content="#000000"><base href="/centreon/"><title>Centreon - IT & Network Monitoring</title><link href="./static/vendor.e7f5e355.chunk.css" rel="stylesheet"><link href="./static/main.63dc8264.chunk.css" rel="stylesheet"></head><body style="margin:0;padding:0;width:100%;height:100%;"><noscript>You need to enable JavaScript to run this app.</noscript><div id="root"></div><script src="./static/runtime~main.8ea6ce4e.js"></script><script src="./static/vendor.86e00385.js"></script><script src="./static/main.d22bec88.chunk.js"></script></body></html>
Thanks for all your help, @Kriko.
Alex.
To complete: old bug of the 20.10 version.
Normaly a yum reinstall centreon-web do the trick for us.
