unable to start httpd service on centos while installing zabbix

[shubhra]

Hi,

I'm new to zabbix and installing it on my centos server.

I followed the link - http://tecadmin.net/install-zabbix-n...el-and-fedora/.

After installing apache, php and MySQL when I start the httpd service I got the following error:
__________________________________________________ ______
[root@centos-512mb-sgp1-01 ~]# service httpd start
Redirecting to /bin/systemctl start httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

In journalctl -xe, it is showing the following error:

Could someone please help me to understand what is going wrong?

Thanks in advance.

do you have htaccses ?
can you post /etc/http/http.conf ?
do you use root user ?
can you check what is using port 80 ?

Thanks, yes nginx was listening on port 80. changed the port to 8081. issue got resolved.
