Apache not starting; httpd not working

Question

I have apache installed on RHEL 7.2 and here is what I see upon starting apache as a root user:

[root@exampledomain conf]# sudo apachectl start
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
[root@exampledomain conf]# systemctl status httpd.service

After running the other command as a root user journalctl -xe, I saw the following:

I saw this post with the same error and tried to see the list of ports using the command mentioned over there netstat -punta | grep LISTEN but couldn't figure out what's the problem.

The result of netstat -punta command is as follows:

where  YY.YY.YY.YYY  is my system IP address.

       XX.XX.XXX.XX  is the server on which Apache is installed

What was the output of `netstat -punta`? Edit it into the question. — Tero Kilkanen, Mar 06 '17 at 18:00
@GeraldSchneider Apache seems to be not running and hence no logs are generating. — Tan, Mar 06 '17 at 18:50
Apache always writes into the error log if it is unable to start — Gerald Schneider, Mar 06 '17 at 19:50
@GeraldSchneider Thanks. In today's log I saw `AH00171: Graceful restart requested, doing restart ` — Tan, Mar 06 '17 at 19:58

Run

 journalctl -u httpd.service

and find the exact error. if response like enter image description here

this happen because of

httpd (pid 5228) already running

So kill that process. (find pid using above command)

 kill 9 5228

then start the httpd service.

service httpd start
