Selamat datang di blog saya, kali ini saya akan membagikan bagaimana cara untuk mensetting ip address pada CentOS 7. Caranya sangat mudah, silahkan ikuti langkah – langkah berikut ini :

• Setting Hostname

[root@localhost ~]# hostnamectl set-hostname reshajtama.my.id 

• Mendisplay interface

[root@localhost ~]# nmcli d

DEVICE       TYPE      STATE      CONNECTION
eth0         ethernet  connected  eth0
lo           loopback  unmanaged  --

• Setting IPv4 dengan nmcli

[root@localhost ~]# nmcli c modify eth0 ipv4.addresses 192.168.1.10/24 

• Setting Default gateway

[root@localhost ~]# nmcli c modify eth0 ipv4.gateway 192.168.1.1

• Setting DNS (Domain Name Server)

nmcli c modify eth0 ipv4.dns 8.8.8.8

• Restart & reload setting

[root@localhost ~]# nmcli c down eth0; nmcli c up eth0

Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1) 

• Melihat semua settingan itu

[root@localhost ~]# ip addr show

1: lo: <LOOPBACK,UP,LOWER_UP> 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: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:cd:9c:2d brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.10/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fecd:9c2d/64 scope link
       valid_lft forever preferred_lft forever

ya berikut adalah bagaimana kita memanagement ip address, hostname dan DNS pada Centos 7.
