httpd instance not starting in RHEL

Issue

• Apache httpd instance present in /my/path/to/httpd/ can start manually but it is not starting with systemctl command.

  [root@myhostname]# /usr/sbin/httpd -f /my/path/to/httpd/conf/httpd.conf
  [root@myhostname]# systemctl start myhttp.service
  Job for myhttp.service failed. See 'systemctl status myhttp.service' and 'journalctl -xn' for details.
