In some occasions after installing Zabbix Server the following message gets displayed at the home screen
This issue is related to the Linux Security Module (SELinux) which is a mandatory access control (MAC) security mechanism implemented in the kernel
The best and recommended option to fixing this is to add a policy to allow the connection
– Run the command “getsebool -a“. Locate the following line which should give you a value ‘–> off“
httpd_can_network_connect –> off
– Run the command to turn it on
setsebool httpd_can_network_connect on
– Now run the command “getsebool httpd_can_network_connect“. The result should now indicate that the policy is now set to ON
setsebool -P httpd_can_network_connect on
Now the Zabbix alert message should disappear and also the “Zabbix server is running” value should now show ‘Yes‘
