Marcus,
My two servers' ids are different. Since there is such setting, replicate-same-server-id=0
is that means server probably could execute its own updates by mistake?
Thanks, Marcus.
To answer another question: although there is no update on one server, it is master -
slave replication. I just to prepare for future, when we shutdown master and run on
slave, after master is up, I don't need to sync database.
