I am using centos7.



I was trying to change the port of ssh and I changed the the port in /usr/lib/firewalld/services/ssh.xml



I also change the port in the /etc/ssh/sshd_config file



But when I tried to start the sshd service by "systemctl start sshd" then I am getting the following error.

    If you have SELinux enabled (getenforce shows "Enforcing"), you will need to adapt the security policy to allow sshd to listen to a port other than the default 22.
