I have installed a fresh copy of Centos 7. Then I restarted Apache but the Apache failed to start. I have 3 days stucked in this issue. Even the support can not figure out the error.
sudo service httpd start
Failed to start apache :
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

I got the same error because of a simple typo in vhost.conf. Remember to make sure you don't have any errors in the config files.
apachectl configtest
