Hi, Ralf!
Read documentation once again:-).
Configure first server as master and second as slave.
And in the same time
Configure first server as slave and second as master.
This will make a ring chain. Test it. You will be surprised. It works. You
can work with both servers in any sequence, stop and start them. Both
databases will be synchronized. They are clever - these boys in MySQL team.
