changing a slave to a master in mysql replication
Currently to make a slave a master, the docs say you need to set the bin-log option in my.cnf on the slave, and that will make the transition to master quicker. I know I can manually change a slave to a master by stopping the slave process, stop mysql, take a snapshot of the databases, copy over a new master my.cnf, make sure I have granted rights to a user for the old master to return as a slave, and restart. My question is how does having the bin-log option on the slave actually help this process? Or is there an easier way to convert a slave to master using the log position that I missed? Thanks in advance for any help. ~Vicky - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: changing a slave to a master in mysql replication
bin-log in 'needed' for a server to act as a master. This will make the server log all it's queries for the slave to follow. Don't know of a faster way.

Thanks for the prompt reply, I understand why bin-log is needed for a master, but I was questioning the usefulness of having the bin-log setting for a slave while it's running as a slave. When the slave becomes a master, doesn't it need a new my.cnf (which would have the bin-log set) or can it become a master with its slave my.cnf? If it can become a master using the slave my.cnf (which has the bin-log set) what commands would I need to call to make it a master now, and no longer a slave to its old master?

Re: changing a slave to a master in mysql replication
As far I know, it would help to leave it set. All the queries executed by the slave to follow the master have the master's server id associated with them. The one's which don't have that id will be replicated by the new slave(old master), there by making the process easier and faster.
