   • CentOS 7, CloudLinux 7, or RHEL 7:

     1 2	systemctl stop NetworkManager systemctl disable NetworkManager

2. Change to the /etc/sysconfig/network-scripts directory.

3. Open the ifcfg-eth0 and ifcfg-lo files with your preferred text editor and, if they exist, set the following keys’ values:
