Subject: mysqld_multi & different server versions
In my ongoing quest to get upgraded to 4.1.3 beta (yes the version I'm
upgrading to keeps changing), i have been reading about mysqld_multi to
manage multiple server instances on the same machine.
But, from what i've read, it appears that this is for running multiple
instances of the same server version on one box. Same binary anyway. I
this because all the examples show as varying are the socket, port,
datadir, language, and user.
The [mysqld_multi] directive for my.cnf points mysqld at a particular
mysqld_safe, which would imply that all the instances would use the same
So am i correct in thinking that i wont be able to use mysqld_multi for
running two different server versions? This shouldn't be a problem, I
think i'll need it. Just wanted to check if im missing something.
