I'd do it this way:
i) Stop mysql
ii) Remove (pkg_delete) the mysql-server package
iii) Move the database files to their new location, taking care to
preserve ownership, permissions, timestamps etc.
iv) Reinstall the mysql-server port setting a different DB_DIR on
the make command line:
# make DB_DIR=/usr/local/db install
v) Make sure that the home directory of the mysql user account is
the same as you set DB_DIR to. The port should take care of
that, but it won't hurt to double check.
% grep mysql /etc/passwd
mysql:*:88:88:MySQL Daemon:/usr/local/db:/sbin/nologin
vi) Restart the mysql server. Verify that your data survived the
move.
And that's it: you're done.
Cheers,
Matthew
