Assuming you are using eth0
Note this will work for any version of CentOS and basically any version of Redhat Linux or Redhat based distribution.
You would need to create a new file
the ":0" at the end specifies alias 0 we could actually change this to ":99" or ":blabla" and it will still work.
The rest should be straight forward as long as you know how to set a static IP in general.
Edit your new file:
And it should look like this:
One more thing, to apply the changes and make them active and test what happens after a reboot
type [code:1:14b16772c8]"service network restart"[/code:1:14b16772c8]
One more thing, it can be a great thing to have a combination of a "DHCP" dynamic IP address and setting a static one.
This sort of guarantees network connectivity, say eth0 doesn't get an IP lease from the DHCP server then your server is basically down.
But if your eth0:0 alias is set statically then you can connect through the static IP address.
It just makes good sense!
