How to change the IP address in Plesk for Linux

Question

A new network interface with a new IP address has been assigned to a server, or an IP address has been updated on an existing network interface (for example, via ifconfig utility).

How to switch all subscriptions to a different IP address on a Plesk for Linux server?

Answer

For Windows, please refer to the following article. 

Note: The new IP should not be added under Plesk > Tools & Settings > IP Addresses before applying the instructions below. Remove it if it's already added.

1. Connect to the server via SSH.

   Note: If direct SSH access to the server is not possible, contact a server administrator for further assistance.

2. Generate a mapping file with current Plesk IP addresses by running the following command:

   # plesk bin ipmanage --remap /root/ip_map_file_name

3. Open the file /root/ip_map_file_name for editing, for example, using vi text editor. To switch all subscriptions from the IP address 203.0.113.2 to 203.0.113.3 edit the file as below:

   Before:

   venet0 203.0.113.2 255.255.255.255 -> venet0 203.0.113.2 255.255.255.255

   After:

   venet0 203.0.113.2 255.255.255.255 -> venet0 203.0.113.3 255.255.255.255

4. Reconfigure Plesk and its services by running the same command again:

   # plesk bin ipmanage --remap /root/ip_map_file_name

Note: Network interfaces are modified in runtime and config (e.g. if the IP address is to be changed to 203.0.113.2/32, while the interface has 203.0.113.2/24, or the main interface itself is to be changed) during the execution of the plesk bin ipmanage --remap utility. If the old IP address(es) are not needed anymore, remove them from Tools & Settings > IP Addresses and after that from the network interface manually. Vote for IP replacement on the interface on UserVoice.
