nginx service wouldn't start

Hello,
I'm trying to run nginx server on CentOS7 and getting the following errors:

`Job for nginx.service failed because the control process exited with error code.`

When checking for a status I got the following:

` Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Tue 2016-04-19 15:25:56 CEST; 57s ago
Process: 19132 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=1/FAILURE)
Process: 19130 ExecStartPre=/usr/bin/rm -f /run/nginx.pid (code=exited, status=0/SUCCESS)
Main PID: 18515 (code=exited, status=0/SUCCESS)`

Is it any suggestions where should I start to debug? Thanks.
