I have currently a setup like this Server 1 that is EOL ( i686 GNU/Linux / Debian 11.7) as MASTER Nothing on it except ispconfig Master MariaDB10.5 Server 2 and 3 ( x86_64 GNU/Linux / Debian 11.7) as SLAVE Apache / MariaDB / website The master is at is end because of 32 bit and i have issues with mysql and other things. now im trying to switch to a two node setup so that Server 3 became the new master and i can shutdown Server1 and reconfigure Server 2 to connect to Server 3 i know its not a recomendet way, but the solution to setup a new Server and restore configs as Master is not a Solution is there any tutorial or help do do someting? currently i planed to dump the Server 1 and Server 3 DB as Backup then i clear Server 3 and restore server 1 DB on it. and change some values in the db so that server 3 knows that he is the master and know his sites and change connection on server 2 to server 3 instead of server 1 any better idea?
In general, you can do that as you described it, but might be a bit wor work and tweaking server ID's in the database. No, I don't think that there are any guides on that topic available.
Yes i doo but i dont think it will work, because i have on server 2 and 3 allready data on it and the data from server 1 is useless / Nothing or did i miss some options?
