Zabbix doesn't work

[vsmjoao]

Hi guy, I'm John.

I'm trying to configure the Zabbix server but I'm not getting it. The web interface shows that the server isn't working on port 10051.



When I enter the command "systemctl status zabbix-server" it returns this error message:

[root@zabbix ~]# systemctl status zabbix-server.service

How to solve this problem?


I'm using Centos 8 and Zabbix 5.

Hi,

Set Debug to 5, and send here the outoput after starting the server, also look for any clues in jouralctl log

BTW. how have you installed zabbix? Have you gone throught any tutorial? if yes send a link.

[Atsushi]

Please check your SELinux settings.
Is communication from the web server to the zabbix_server process blocked?

ex. If SELinux is enabled

# setsebool -P httpd_can_connect_zabbix on

You may also need to add another setting.

Like Atsushi said it may be down because of Selinux, use this tutorial to configure SELinux for Zabbix.

Thank you. It solved my problem.
