Zabbix Server service does not start: zabbix-server.service failed

[onny92]

Hello everyone,
I have this problem with a Zabbix Server.
Unfortunately the Zabbix Server service does not start.
I kindly ask for help.


[root@localhost ~]# systemctl status zabbix-server
● zabbix-server.service - Zabbix Server
Loaded: loaded (/usr/lib/systemd/system/zabbix-server.service; enabled; vendo r preset: disabled)
Active: activating (auto-restart) (Result: exit-code) since Thu 2023-07-13 14 :30:14 CEST; 3s ago

Process: 2364 ExecStart=/usr/sbin/zabbix_server -c $CONFFILE (code=exited, sta tus=0/SUCCESS)
Main PID: 2366 (code=exited, status=0/SUCCESS)

From the logs I get the following:
