"ps" shows zabbix_server running, but server not listening on port 10051

[mahoneys]

I'm trying to install Zabbix 3.2 on Centos 7.1. I was getting errors on trying to start with "systemctl start zabbix_server" until I installed trousers. Now it starts just fine.

I can see zabbix_server is running, since I can see it in ps. When I try to telnet to port 10051 I get "Connection refused".

zabbix-agent is also running, and I can see in lsof and in netstat that it has port 10050 open, and I get a connection when I telnet to 10050.

So my question is, why is port 10051 not open when zabbix_server is running?

Please check the log of the Zabbix server. (/var/log/zabbix/zabbix_server.log)
Are some error messages output to the log file?

If you found below error in /var/log/zabbix/zabbix_server.log

So zabbix is listening but you cannot connect

Firewall? SELinux AVCes?
