Joey, " I can not afford any downtime and the data is realtime. "
This is a very good reason for asking help to consultants. If you ask "What is the best method for this setup? master-master or master-slave?" then the simple answer is master-slave, for any mysql setup, that is the only safe mysql replication setup. If you mean Master-Master Active/Passive I still consider that Master-Slave. While is very well advisable to stay away from master-master active/active, unless you really know what you are doing and you have the development aware, very skilled, and listening to you*. So, go for master-slave, but I would suggest to read online mysql manuals and some great books, because if you post here to ask every single step to set it up, you are basically asking someone else to do the job for you, for free ;) Cheers Claudio 2012/6/12 Joey L <mjh2...@gmail.com> > It sounds like you are all consultants. > > > On Mon, Jun 11, 2012 at 4:46 PM, Baron Schwartz <ba...@xaprb.com> wrote: > > Yeah -- that was an unintentional omission.
