#Centos 7 static ip configuration how to
In RHEL 8, if you make changes in the ifcfg file, NetworkManager needs to be informed. The scope of this tutorial is to explain how we can edit and make changes to Network Configurations on RHEL/CentOS 8/7 from the command line only, and, more specifically how we can set up a Static IP address on network interfaces using system network-scripts, which is a must be configured to serve Internet-facing network services, and how to configure or change RHEL/CentOS system hostname. Set the IP address and other information as per your requirement. vi /etc/sysconfig/network-scripts/ifcfg-enp0s3 For interface enp0s3, the file name would be ifcfg-enp0s3. In this method, we will edit the network interface file ifcfg-ifname under /etc/sysconfig/network-scripts/ directory. We can set a static IP address to the network interface by using below methods.Ģ. Available Network Interfaces Configure Static IP Address Here, we will configure the static IP address for enp0s3. The output of ifconfig -a may look like below.

The server has to be configured with IP address so that it can be accessed over the network. We have two methods to add permanent static routes in CentOS 7. They will get removed if you restart the network or if the server rebooted. While both commands work the same way, neither command can use to add permanent routes to the system. The first task of an administrator who installs an operating system is bringing the server into the network after the OS installation. Usually we add ip routes in Linux using either route command or ip route command.
