I am running dual master MySQL replication and now want to move to a single database with no replication. How do I completely disable replication on both databases?
To completely disable replication with a master-master setup, you should do the following on each slave:


STOP SLAVE;
RESET SLAVE; (Use RESET SLAVE ALL; for MySQL 5.5.16 and later)
Edit the my.cnf and remove any information (if present) which refers to "master-..." or "replicate-..." options.  You may not have anything in the my.cnf, since replication can be setup dynamically as well.
Restart mysqld.
