Dear support, I have a multiserver setup and I would know if it's possible to unlink one of the slaves servers by keeping the data. In this case it's a mail server with many domains declared on it, and I want to make this server a standalone server, but I want to keep all the configuration. I have cloned the VM and started the ISPconfig update but it asked me the MySQL master server hostname directly. Could you please help me to solve this ? Thank you for your help. Best regards.
I've never done this, but the steps would more or less be: - make an extra copy of your vm clones (master server and slave server) so you can start over if needed - after cloning the slave, dump the database from the master server and import that as the dbispconfig database on the slave - you can then (or later if preferred) delete all those email domains from the master (and anything else, as needed), and delete the old slave server under System > Server services (and anywhere else it would still exist) - in the old slave/new standalone server, edit ISPConfig's config.inc.php in both /usr/local/ispconfig/interface/lib/ and server/lib/ to set server_id=1 and delete the dbmaster host/port/user - in the database on the new standalone server (old slave), delete all entries from the server table except for server id 1, and change the values for id 1 to be appropriate for the new standalone server (hostname, mail settings, etc.) - update firewall (I think 'iptables' table) for server_id 1 with full set of needed ports, and delete rows for other server id's - update or delete server_ip and server_php tables so only server id 1 exists, with correct values - still in that database, change the server_id column in all other database tables to be "1" - install any missing software on the new standalone server per the Perfect Server guide (eg. you might need a web server, more php packages, etc.) - I'd probably make another quick clone/snapshot at this point, then run the ispconfig updater to reconfigure services - login to the ISPConfig interface (eg. port 8080 by default) and clean up "everything" (delete websites, dns zones, etc. .. everything but your email domains, it sounds like) - tools > resync (everything) - change email related dns records for the domains to use the new server - you might be done, test everything, troubleshoot and fix whatever was missing
