Cara seting ip address linux redhat

Cara seting ip address linux redhat

1. Backup file Konfigurasi di folder \bkup

–  Buat folder \bkup untuk backup file konfigurasi ip address

[root@localhost /]# cd /
[root@localhost /]# mkdir bkup
[root@localhost /]# ls
bin   boot  etc   initrd  lost+found  mnt  proc  sbin      tmp  var
bkup  dev   home  lib     misc        opt  root  tftpboot  usr
[root@localhost /]#

–  Copy file ifcfg-eth0 ke folder /bkup

[root@localhost /]# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /bkup/ifcfg-eth0.backup

2.  Setting IP Address Static dgn ip 192.168.1.10

–  Edit file ifcfg-eth0

[root@localhost /]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

–  Lalu isi file ini sesuai konfigurasi dibawah ini

DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.10
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
USERCTL=no
PEERDNS=no
TYPE=Ethernet

–  Restart Network Service

[root@localhost /]# sudo service network restart

Shutting down interface eth0:                                   [  OK  ]
Shutting down loopback interface:                           [  OK  ]
Setting network parameters:                                     [  OK  ]
Bringing up loopback interface:                                [  OK  ]
Bringing up interface eth0:                                        [  OK  ]
[root@localhost /]#

–  Melihat konfigurasi IP address

[root@localhost /]# ifconfig
