How to do : Add or Delete an IP Address in the VPS

Hello there,

Usually, we need to add or remove an IP address in the VPS. Here we go :

Prerequisites

You need Node Server access for these (then only you can manage those VPS), that too SSH root access. The VPS should be either OpenVZ or Virtuozzo.

Steps

Say we are logged into the Node Server. There we are going to list all the Containers existing on the Hardware Node. By default, only running Containers are shown.

[root@linuxvps1 ~]# vzlist -a
CTID    NPROC STATUS   IP_ADDR        HOSTNAME
100     18  running    100.20.11.111  WEB.EXAMPLE.COM
101     63  running    100.20.12.203  -
102     169 running    100.20.92.182  server2.example.com
103     81  running    100.20.56.169  test.example.net
78965   236 running    100.20.77.204  server1.example.com

Lets consider the VPS with ID 78965 needs the new IP 100.20.80.200 to be added. So the command will be :

[root@linuxvps1 ~]# vzctl set 78965 --ipadd 100.20.80.200
Adding IP address(es): 100.20.80.200 WARNING: Settings were not saved. On next start the original values will be applied.
Use --save to save the settings in the configuration file.

Save the Settings (this command will do the purpose instead of the above one)

[root@linuxvps1 ~]# vzctl set 78965 --save --ipadd 100.20.80.200
Adding IP address(es): 100.20.80.200 Saved parameters for Container 78965.

Thats it, now login to WHM and access ‘Change Site’s IP Address’. Select the website and change the IP address from the drop down list.

To remove an IP from the VPS

[root@linuxvps1 ~]# vzctl set 78965 --save --ipdel 100.20.80.200
Deleting IP address(es): 100.20.80.200 Saved parameters for Container 78965.

Mission Accomplished !
