How to configure a static ip in Linux using Console?

Configuring your Linux machine to run on a static IP is easy. You can do that both from Console and GUI.

This tutorial is to configure a static ip in Linux using Console. Follow following steps : 

  a)  Go to 

    # cd /etc/sysconfig/network-scripts/

    Every network interface will have it’s own interface script files. 
   
    For Ex - eth0,eth1,eth2 etc. 

 b) Edit ifcfg-eth1 interface script file for interface eth1.  

    Replace the contents of the ifcfg-eth1 file with the parameters below.

    # vi ifcfg-eth1

    DEVICE=eth1
    IPADDR=xxx.xxx.xxx.xxx
    NETMASK=255.255.255.0
    NETWORK=xxx.xxx.xxx.0
    # If you're having problems with gated making xxx.xxx.xxx.0/8 
    #  a martian, you can change this to something else 
    #  (255.255.255.255, for example)
    
    BROADCAST=xxx.xxx.xxx.255
    ONBOOT=yes
    NAME=loopback

 c) Save the file and restart your interface to apply changes.

    # ifdown eth1

    # ifup eth1

    # service network restart

 d) That's it :)
