How do I replace IP addresses for objects in Parallels Plesk?

Resolution

Note: Before manipulating the database, it is strongly recommended that you create a backup.

In the most simple case, where all your domains' IPs need to be updated to a single value, you can use the following script. Replace <IP address> with the IP you want domains to be switched to:

# mysql -Ns -uadmin -p`cat /etc/psa/.psa.shadow` -D psa -e 'select name from domains' | awk '{print "/usr/local/psa/bin/domain --update " $1 " -ip <IP address> "}' | sh

Also, you can omit the last | sh directive to preview the output of command before executing it.

If you need to perform a more complex IP change (e.g. if you have more than one destination IP and you need to specify which IP becomes which), you can use the reconfigurator.pl script.

The utility ${PRODUCT_ROOT_D}/reconfigurator.pl is developed to replace IP addresses assigned to objects (domains/clients/resellers) in the Plesk database and to reconfigure object settings with the new IPs:

# /usr/local/psa/bin/reconfigurator.pl
Plesk reconfigurator - utility to change IP addresses used by
Plesk Server Administrator

Usage:
    /usr/local/psa/bin/reconfigurator.pl <map_file>

 If <map_file> doesn't exist, a template will be created. Otherwise,
it will be used to map IP addresses.

Follow these steps to perform the IP address replacement:

  1. Make sure the new IP addresses are not registered in Plesk on the Server > IP Addresses page. If they are, remove them before proceeding further.

  2. Run the utility to create the mapping template file:

    # /usr/local/psa/bin/reconfigurator.pl ipaddresses.map
    

    Then, edit this file and set the appropriate IP mapping. Map file matches in the full list of the currently configured IP addresses with new ones in the following format:

    #cat ipaddresses.map
    eth0:192.168.50.60 255.255.255.0 -> eth0:192.168.50.60 255.255.255.0
    eth0:192.168.50.70 255.255.255.0 -> eth0:192.168.50.70 255.255.255.0
    

    Edit the file and replace an IP address in the right part of a string with one from the new set:

    eth0:192.168.50.60 255.255.255.0 -> eth0:new_ip_address 255.255.255.0
    
  3. Once the mapping file contains an appropriate arrangement, run reconfigurator.pl again:

    # /usr/local/psa/bin/reconfigurator.pl ipaddresses.map
    

    It will read the mapping file and perform the replacement according to its content.

  4. Repair the configuration for Plesk services:

    # /usr/local/psa/bin/repair -r
