- Plesk for Linux
Plesk IP address cannot be removed:
PLESK_ERROR: Error: Cannot remove the IP address 203.0.113.2 because it is the primary IP address of a network interface.
PLESK_ERROR: ifmng failed: cannot delete main IP on interface
Primary IP address of network interface cannot be removed by design.
Note: This solution is applicable only if there are at least 2 IP addresses on a server. To add a new IP address, see this KB article.
Connect to a Plesk server via SSH.
Create a backup of Plesk database:
# plesk db dump psa > /root/psa_backup.sql
Connect to the Plesk database:
# plesk db
Note: In the following example:
203.0.113.2 - the current main (primary) IP address
203.0.113.3 - the new main (primary) IP address that is going to replace 203.0.113.2
Change value of the main field to "true" for the new IP address:
MYSQL_LIN: mysql> UPDATE IP_Addresses SET main='true' WHERE ip_address='203.0.113.3';
Change the value of the main field to "false" for the old IP address:
MYSQL_LIN: mysql> UPDATE IP_Addresses SET main='false' WHERE ip_address='203.0.113.2';
