Zabbix 2.4 new install, "zabbix server is not running" in webinterface

[pxsh]

Hello,
Recently installed Zabbix 2.4 on a fresh CentOS, following the steps on https://www.zabbix.com/documentation..._from_packages page, however the webinterface refuses to accept that Zabbix server is running.

both /etc/zabbix/web/zabbix.conf.php and /etc/zabbix/zabbix_server.conf seems to be correctly configured.

Checking Host configuraton for the "Zabbix server" shows an blue "Z" indicating that the agent is running and connecitivity between agent and server is ok.

Any tips on how to solve this ?

Edit:
After many many google searches I found that it was SELinux related, which I forgot was enabled by default on fresh installs of CentOS.

Setting the SELinux mode to "permissive" enabled the communication: setenforce permissive

In this mode the SELinux will not enforce but inform instead.

Temporary solution of course, really need to dig into SELinux and set correct rules but this will hopefully be good information for anyone else struggling with this.

Hej,

What version of CentOS are you using? 6.x or 7? SELinux settings differ on those.

Some useful commands that can help you and leave SELinux in Enforcing mode.

getsebool -a

Shows current status for applications in SELinux.

setsebool -P zabbix_can_network=true

Allows Zabbix through network. I don't recall but I think this was the cause for "zabbix server is not running"

setsebool -P httpd_can_network_connect=true

Allows connects to web interface.

I think this was enough on CentOS 6.6. On 7 it was more. I have to look up, if you need.

Best Regards,
Ingus

Thanks Ingus, those 2 commands fixed the issue for me on CentOS 6.6.
