Good job, Mike! You nailed it, though what some of the other helpful
folks wrote had me on the right path, too. For some reason, the
binary-configure after the pkg_add left everything owned by
root:wheel. "cd /mysql ; chown -R mysql:mysql ." was the solution.
After that, everything came out and flew straight! Somehow, the mysql
user and group got created, but everything was still owned by root:wheel.
Just for the record, my rc.conf had already contained:
Also for the record, the last one is ignored. The pid file
is still in /mysql/`hostname`.pid
So - for those of you who said "don't try to run it anywhere but
/var/db/mysql" - maybe you're right. Maybe that's what led,
indirectly, to the ownership not getting set correctly. But, once
you know the problem, the solution is simple, and it's now doing a
great job of running where I want it to run.
