Zabbix-Server is not running (but does)

[christianmolecki]

Hello,

I migrate my zabbix installation to a new server.
So I made a fresh zabbix installation and import the database.
Simultaneously the MySQL-Server changed from MySQL v5.7 to v8.0

Zabbix-Server: 5.0.22
MySQL-Server: 8.0.29
PHP: 7.4

The Zabbix-Front shows a warning: "Zabbix Server is not running: the information displayed may not be current"
Zabbix-Server is running: No (localhost:10050)

Everything seems to be fine. Zabbix collects data from the agents properly.
In case of a alert, mails will be send.


@ Administration -> Queue
Cannot display item queue.
Incorrect response received from Zabbix server "localhost".

Does anyone know, what to do?


Best Regards
Christian

This sounds like a situation where the zabbix_server processes are running just fine, but the Zabbix web front-end either can't communicate with it (perhaps firewall or SELinux/AppArmor blocking it?) or is trying to communicate with the wrong server.

It seems like the database settings (the PHP variables that look like "$DB['TYPE']", etc.) in zabbix.conf.php are probably set correctly, but what about the "$ZBX_SERVER_*" variables? Are those correct for your new server?

Does your firewall or other security mechanism (SELinux, AppArmor, etc.) prevent communication with localhost port 10051?

Hello Tim,

thank your for your help.

The configuration file zabbix.conf.php didn't had in my mind.
After a valid configuration, zabbix works fine.
