    When i change the Listen directive and restart the httpd following error occurs.

    Job for httpd.service failed. See ‘systemctl status httpd.service’ and ‘journalctl -xn’ for details.

    This happen when i tried to change Listen to 3221, 9090 or :9090 .. anything.
    While it works fine for port 80 and 8080

      Hi Atul. This could be caused by SELinux. Check if it is enabled by running “sestatus“. If it says enabled, you have to ways:

      1. Disable SELinux by running ‘setenforce 0‘;
      2. Add SE rules (using ‘semanage‘ command). In this case you will have SELinux enabled (which is recommended);

    Use Secure Protocol over the default SSH Protocol and change port number also for extra Security. Edit the SSH configuration file ‘/etc/ssh/ssh_config‘.
