In this small tutorial i will explain how to configure static ip address on CentOS 7 minimal.
First, need to edit the set up for the ethernet. Let’s start with editing “/etc/sysconfig/network-scripts/ifcfg-enp0s3″ file:
vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
HWADDR=08:00:27:6C:FF:91 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPADDR=192.168.0.88 IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=enp0s3 UUID=ea68db6e-461e-427d-b9a8-bfcf6e1a4fc6 ONBOOT=yes
Save and exit.
Now, configure default getaway:
vi /etc/sysconfig/network
And add following line:
NETWORKING=yes HOSTNAME=centos7 GATEWAY=10.1.1.253
Configure DNS Server
vi /etc/resolv.conf
add following line:
nameserver 8.8.8.8 nameserver 8.8.4.4
Now restart your network or rebooting system
/etc/init.d/network restart
Check your network:
ip addr
1: lo: mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 08:00:27:6c:ff:91 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.88/24 brd 192.168.0.255 scope global enp0s3
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fe6c:ff91/64 scope link
valid_lft forever preferred_lft forever
That is all.
