I'm new to clustering and I'm trying to implement a Galera cluster. I'm transitioning from a standalone MySQL instance to a MariaDB Galera Cluster consisting of (at the moment) 2 nodes.
I have installed MariaDB-Galera-server.x86_64 10.0.13-1.el6 & MariaDB-client.x86_64 10.0.14-1.el6 on a CentOS 6 server.
I have also converted all the MyISAM tables to InnoDB.
My question is how do I make the switch? I was reading the (old?) codership notes on how to set up the my.cnf (https://web.archive.org/web/20131021065420/http://www.codership.com/wiki/doku.php?id=mysql_galera_configuration) and they say that these parameters are Required:
My current log file (even though it's a standalone instance and not a cluster) is statement based and my database has a lot of data. How does making this change affect my current logs and current data?
Should I just make changes as per the my.cnf listed in the codership example file and play around until I get it right? Any other advice before I get started?
