ip addr
3 , copy the ifcfg-eth0 file in the /etc/sysconfig/network-scripts/ directory and name it ifcfg-eth5.
cd /etc/sysconfig/network-scripts/ cp ifcfg-eth0 ifcfg-eth5
4. Re-modify the configuration file , pay attention to modify the necessary hardware information.
vi ifcfg-eth5
5. Restart the network card.
service network restart
6. Check the IP again, it’s already fine and it won’t change in the future
ifconfig
