Set the manual configuration (from dhcp to static), ~]# nmcli con mod enp0s3 thod manual

Set the gateway using below nmcli command, ~]# nmcli con mod enp0s3 ipv4.gateway 192.168.1.1

Note: In short form, we usually replace connection with ‘con’ keyword and modify with ‘mod’ keyword in nmcli command.Īssign ipv4 (192.168.1.4) to enp0s3 interface, ~]# nmcli con mod enp0s3 ipv4.addresses 192.168.1.4/24 Use beneath nmcli command to assign static ip on enp0s3, List currently active Ethernet cards using “ nmcli connection” command, ~]# nmcli connectionĮnp0s3 7c1b8444-cb65-440d-9bf6-ea0ad5e60bae ethernet enp0s3 Run the following nmcli commands one after the another to configure static ip, Let’s assume we want to assign the static IP address on first NIC (enp0s3) with the following details, Currently ip address assigned to the NIC is via dhcp server. It can not be used to set additional static routing for interface.Run the below ip addr command to list Ethernet cards on your server ~]# ip addrĪs we can see in above command output, we have two NICs enp0s3 & enp0s8. This method can only set the default gateway. If you don’t have X windows GUI (gnome/kde desktop) installed on CentOS server / system, than type the following command at shell prompt. Do not use both files to configure default gateways. Avoid setting duplicate default gateways either use /etc/sysconfig/network or /etc/sysconfig/network-scripts/route-ethX file. Sample configurations: default 192.168.2.254 dev eth1Īlert: For eth0 interface use /etc/sysconfig/network-scripts/route-eth0 file. # cat /etc/sysconfig/network-scripts/route-eth1 The default gateway set to 192.168.2.254, interface eth1. The following is a sample route-eth1 file.

# ping # host CentOS Linux static routing config for eth1 interface

To verify new settings ping to the default gateway and external network: Restart the networking service on CentOS Linux, type: GATEWAY = 192.168.1.254 NETWORKING_IPV6 = yes IPV6_AUTOCONF = no
