用户应该在Mac上拥有/ usr / local / mysql？

Question

What should the file owner & group be of /usr/local/mysql and all contained files & directories? MySQL was working fine, but after I did sudo chown -R $USER:staff /usr/local to install Homebrew , MySQL couldn't automatically start on startup, and on the MySQL Preferences panel, I got "Warning: The /usr/local/mysql/data directory is not owned by the 'mysql' or '_mysql' user," and when I clicked Start MySQL Server, it didn't connect.

To fix this, I ran sudo chown -R _mysql:wheel /usr/local/mysql/data . Then, I closed & opened System Preferences. The warning went away, and when I clicked Start MySQL Server, it started!

MySQL seems to be responding fine now, but I just guessed at this solution. Is what I did correct?

Answer 1

Looks valid to me. This is what my mysql folder looks like:

drwxr-xr-x  17 root    wheel    578 May  7  2010 .
drwxr-xr-x   8 root    wheel    272 Jun 11  2010 ..
-rw-r--r--   1 root    wheel  17987 May  7  2010 COPYING

drwxr-xr-x  16 root    wheel    544 May  7  2010 support-files

How did you install MySQL it if it didn't hook everything up correctly itself?

EDIT: and this is the general flavor of the data folder:

drwxr-x---  15 _mysql  wheel       510 Jan 24 08:15 .
drwxr-xr-x  17 root    wheel       578 May  7  2010 ..
-rw-rw----   1 _mysql  wheel    158773 Jan 24 08:16 $USER.local.err
-rw-rw----   1 _mysql  wheel         4 Jan 24 08:15 $USER.local.pid
drwx------   6 _mysql  wheel       204 Jun 16  2010 $SOME_DB_NAME1
drwx------   6 _mysql  wheel       204 Jun  8  2010 $SOME_DB_NAME2
drwx------  15 _mysql  wheel       510 Jan 18 11:23 $SOME_DB_NAME3
drwx------  12 _mysql  wheel       408 Jan 20 14:40 $SOME_DB_NAME4

-rw-rw----   1 _mysql  wheel  18874368 Jan 21 17:31 ibdata1
drwx------  85 _mysql  wheel      2890 Jun  3  2010 $SOME_DB_NAME5
drwx------  85 _mysql  wheel      2890 Jun  3  2010 $SOME_DB_NAME6
drwxr-x---  71 _mysql  wheel      2414 Jun  3  2010 mysql
drwx------  21 _mysql  wheel       714 Aug 31 17:27 $SOME_DB_NAME7

I don't run Homebrew on my machine, tho, so I dunno if this is of much help as far as that goes.

Answer 2

I had the exact same problem and MattDiPasquale's answer worked for me. I had to keep running mysqld all the time to ensure MySQL was running properly. When I looked at MySQL in the System Preferences I realised I had the same error.
