Hi Garot, How is the visual diagram coming along ?

Re: Replication question: How to make a slave a master?
Are you trying to promote a slave as a new master and replace current master or create intermediate slave? If it is the latter all you need to do is to: 1. Stop the slave 2. Add log_slave_updates = 1 in the slave's config file 3. Copy the slave files to the new slave(s) 4. Start your intermediate slave 5. Add replication user on your intermediate slave and allow new slaves to replicate 6. Start your slave(s) of intermediate slave 7. Issue following on your new slaves: CHANGE MASTER TO master_log_file = 'mysql-bin.01', master_log_pos = 4; On Aug 24, 2012, at 11:25 AM, Richard Reina wrote: I have a couple of mysql database slaves and would like to make one of them be a master as well so that I can set another machine to replicate from it.
