The relevant options are... [EMAIL PROTECTED] ~ $ mysqld --help --verbose | grep default --no-defaults Don't read default options from any options file --defaults-file=# Only read default options from the given file # --defaults-extra-file=# Read this file after the global files are read
I would suggest using the --defaults-extra-file to refer to a defaults file that has only the settings you want. But this is roughly equivalent to restarting with the --replicate-XXX options manually specified, no? You might also look into the Instance Manager, which could give you some more ideas. I'm being vague because I don't know what I'm talking about :-) On Nov 27, 2007 10:19 AM, bruce <[EMAIL PROTECTED]> wrote: > ok... > > you guys have convinced me!! my.cnf it is! > > so, one more question. is there an attribute i can use to run/restart mysql > using a given my.cnf file... i can simply have a number of separate my.cnf > files, and point to them when i run/restart mysql.. > > /etc/init.d/mysqld --??? myown.cnf > > is there an option/attribute for this. > > thanks > > > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Baron Schwartz > Sent: Tuesday, November 27, 2007 6:50 AM > To: bruce > Cc: B.
