Setting Up A Static IP Address Using The Command Line

Log on as root, change directory to /etc/sysconfig/networking/devices and list all available devices.

Quote

    # cd /etc/sysconfig/networking/devices
    # ls

Find the configuration file corresponding to the NIC for which you want to set a static IP and edit it.

Quote

    # nano ifcfg-eth0

I prefer using “nano” as a text editor rather than “vi”.

Now set the parameters below according to your settings (those in bold characters only):

Quote

    DEVICE=eth0
    BOOTPROTO=none
    HWADDR=00:0C:29:DE:94:8B
    ONBOOT=yes
    TYPE=Ethernet
    USERCTL=no
    IPV6INIT=no
    PEERDNS=yes
    NETMASK=255.255.255.0
    IPADDR=192.168.0.100
    GATEWAY=192.168.0.1

Save the configuration file and exit the text editor.

To set the nameservers, change directory to /etc and edit resolv.conf.

Quote

    # cd /etc
    # nano resolv.conf

The file format should be like this:

Quote

    search your-dns-search-path
    nameserver dns1-ip-address
    nameserver dns2-ip-address
    nameserver dns3-ip-address

Now save the configuration file and exit the text editor. To apply changes, we need to bring the network interface down and back up.

Quote

    # ifdown eth0
    # ifup eth0

If you intend to do that remotely, reboot the server instead as you would be disconnected from your server after issuing the “ifdown” command.
