For redhat servers:

Ok I got this working myself by playing around and this works for me. Obviously do it at your own risk, yadda yadda, usual disclaimer.

First you need to go to the directory where this junk is
cd /etc/sysconfig/network-scripts

Then as a usual precaution I would make a backup of the file
cp ifcfg-eth0 ifcfg-eth0.bak
(you wont need to do anything with the backup)

Then copy the config for your new IP
cp ifcfg-eth0 ifcfg-eth0:1

Then we need to edit the new config
pico -w ifcfg-eth0:1

The lines you need to change:

DEVICE="eth0"
to
DEVICE="eth0:1"

Then change the
IPADDR="xxx.xxx.xxx.xxx"
to be your NEW ip address (it will have your primary ip listed)

Once this is done, press CTRL + X
then press Y and <enter>

This will have saved the config for you and the interface is ready to be brought up. This is done with
/sbin/ifup eth0:1

Having done this if you type
/sbin/ifconfig

You should see something like
------code------
eth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00
inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.xxx Mask:255.255.254.0

collisions:0 txqueuelen:0
RX bytes:66571100 (63.4 Mb) TX bytes:66571100 (63.4 Mb)
------/code------

If you then try to ping your new ip it should all work fine
This should also restart eth0:1 on a reboot as its a direct copy of the eth0 config. So checking for the ONBOOT="yes" in ifcfg-eth0:1 will ensure it DOES come back up on a reboot.

Hope this helps, and if it doesnt work please let me know so I can investigate where I made a mistake.

Perhaps I should post this to HOW-TO since I too couldnt find it.
