I do understand that is some permission issue but no idea how to fix it !
I would appreciate any suggestion

Please, search a bit in the forum and you will find the solution.

I dont want to be rude, but I wrote the solution more than 10 times.

Search for “Error 500”, “Whoops, something…” etc

3

Please forgive me !
I did search and try to apply all the solutions before I applied to this forum.
It something I missed I will redo all my search
Thank you

4

For your error, seems the solution is step 3

5

I already tried all 3 steps and it did not work out
Please trust me I did search in the community in a last 2 days no joy yet
Here is what i did fallowing your advice:

[root@localhost ~]# cd /opt/librenms/
[root@localhost librenms]# ./scripts/composer_wrapper.php install --no-dev
Do not run Composer as root/super user! See How do I install untrusted packages safely? Is it safe to run Composer as superuser or root? - Composer for details

can you suggest what I could do to troubleshoot

This is what I found and it seems to be the problem or I think it is

production.ERROR: ErrorException: session_write_close(): open(/var/lib/php/session/sess_3c3era69l84ffp9g36kfmr11j4, O_RDWR) failed: Permission denied (13) in /opt/librenms/LibreNMS/Authentication/LegacyAuth.php:121

this is how it looks the line 13 ont the LegacyAuth file

<?php namespace LibreNMS\Authentication; use Auth; use LibreNMS\Config; use LibreNMS\Interfaces\Authentication\Authorizer; class LegacyAuth { protected static $_instance; private static $configToClassMap = array( 'mysql' => 'LibreNMS\Authentication\MysqlAuthorizer',
7

Oh, missread where the permission denied was from.

Does your http user has write access to that folder (/var/lib/php/session )

Also, if you are running php-fpm you must restart it.

I restarted php-fpm
This is what I have in session folder
and it seems that is not the same that he try to use
[root@localhost librenms]# cd /var/lib/php/session "open(/var/lib/php/session/sess_3c3era69l84ffp9g36kfmr11j4, O_RDWR) failed: "
[root@localhost session]# ls
sess_7ogd08brfjhmkuhi36pfpaf0t6 sess_bikomksa38m7tmjo5j1ge1f7g3 sess_s6vvf6566jnm51slk57o9rko81

I will give you the bast feedback ever if we manage to fix this !

What user is php-fpm running as? what are the permissions on /var/lib/php/session and included files ls -lR /var/lib/php?

10

drwxrwx—. 2 nginx nginx 123 Sep 15 22:03 session

This mean it should run apache
[root@localhost ~]# systemctl status apache
Unit apache.service could not be found.
[root@localhost ~]# whereis apache

chown -R apache:apache /var/lib/php/session

Should have you fixed up. Pretty sure your OS just uses the apache user so there isn’t any issues no matter if you use nginx or apache.

15

Okey done do I have to restart php-fpm ?
