How to bind additional IPs?




Instructions are only for CentOS / Fedora specifically.


By default, Rackbank only binds your first primary IP. This is because there are different methods of applying your additional IPs that may require that they not be bound originally.

Here is the simplest way of binding your additional IPs:


1) Find out which interface is public

[root@RBDC## ~]# route | grep -v "10." | grep -m 1 "255.255" | awk '{ print $8 }'
eth1


This shows that my public interface (does not have a "10." address) is eth1.



2) Create the route file


Before running the command below, change "eth1" to your public interface from step 1 and set your START and END IP addresses in the range.


Note:
Your IPADDR_START should be second usable IP as your primary is already bound. The IPADDR_END value is your last usable IP. If you are unsure what these values are please check your welcome e-mail or open a support ticket.

echo "IPADDR_START=103.15.***.***
IPADDR_END=103.15.***.***
CLONENUM_START=0" >> /etc/sysconfig/network-scripts/ifcfg-eth1-range0


3) Restart your network interface

service network restart
