Change VM from DHCP to Static IP

Steps to change DHCP configuration to a static IP, if the VM was originally configured using DHCP. I’ve had to look this up a few times so I’m documenting it here.

Edit the network adapter

• Edit the following file as root user

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
HWADDR=00:1A:A0:B2:B2:5B
ONBOOT=yes
IPADDR=192.168.0.xxx
NETMASK=255.255.255.0
NETWORK=192.168.0.255

And save the file

Edit the hosts file

• Also edit the host file in etc as root user.

/etc/hosts

Do not edit these two lines which is given as default

127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

Add this at the end of the file

192.168.0.xxx aaapum.psadmin.io aapum

Restart the network services

• Restart the network using this command.

service network restart
