Replicating on two or more MySQL master database servers
1.
When you try MySQL master-master replication with two (or more) servers you may often find that in the process of configuring the original master to also act as a slave server (start slave), it fails with the following error:
mysql> start slave;
ERROR 1200 (HY000): The server is not configured as slave; fix in config file or with CHANGE MASTER TO
To rectify it locate and delete the master.info file and restart the mysql server.
I have significantly improved our site performance in the last month.
