Adding and viewing IP addresses on CentOS servers

To add newly assigned IP addresses from SSH, follow this procedure:

(Please follow the steps given below only on a Centos / Fedora.)

  • Login to your server with SSH as root.
  • Go to the /etc/sysconfig/network-scripts directory.
cd  /etc/sysconfig/network-scripts/

Verify which interface you will use to add IP addresses. Typically, this will be eth0 for public IP addresses.

/sbin/ifconfig

Make a copy of ifcfg-eth0 for each IP you wish to add and name them as ifcfg-eth0:0, ifcfg-eth0:1 etc.

cp ifcfg-eth0 ifcfg-eth0:0 
cp ifcfg-eth0 ifcfg-eth0:1
cp ifcfg-eth0 ifcfg-eth0:2
cp ifcfg-eth0 ifcfg-eth0:3
cp ifcfg-eth0 ifcfg-eth0:4

Open each of them and change the fields DEVICE, .IPADDR and NETMASK accordingly.

A sample entry would look like this:

DEVICE=eth0:0
BOOTPROTO=static
IPADDR=34.123.111.21
NETMASK=255.255.255.0
ONBOOT=yes

Restart the network:

/etc/init.d/network restart

To verify what are the IP addresses assigned to your server, please use the following command:
/sbin/ifconfig
