I'm having insane problems installing MySQL with Homebrew on Mavericks. I know there is a similarly named topic, but I have tried everything written there along with at least 20 sites with no success trying to make it work. I tried installing with steps according to different tutorials but nothing works as it should.

I go like this:

brew update
brew doctor
brew upgrade

brew install mysql

Brew installs it in /usr/local/Cellar/mysql/5.6.16 ...

I try connecting as Brew says: mysql -uroot

I make the LaunchAgents directory, link the homebrew plist file to it and launch controls: 

mkdir -p ~/Library/LaunchAgents
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

after that I try and start the mysql server with sudo mysql.server start but I get a socket error

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

I try starting the server with mysqld_safe & but I get the following output:

[1] 69187
Davids-MacBook-Air-5:~ davidsupan$ 140224 14:39:16 mysqld_safe Logging to     '/usr/local/var/mysql/Davids-MacBook-Air-5.local.err'.

/usr/local/bin/mysqld_safe: line 129: /usr/local/var/mysql/Davids-MacBook-Air-5.local.err: Permission denied

The following commands seem to do the trick sudo chmod -R 755 /usr/local/var/mysql rm -Rf /usr/local/var/mysql/Davids-MacBook-Air-5.local.err

mysql.server restart

and the mysql server succesfully starts

Shutting down MySQL
.. SUCCESS! 
Starting MySQL
. SUCCESS!

Other times, no matter what I do, I keep getting the following error

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

Some pages suggest doing

unset TMPDIR
mysql_install_db --verbose --user='whoami' \\
--basedir="$(brew --prefix mysql)" \\
--datadir=/usr/local/var/mysql --tmpdir=/tmp

but I have no success mending this problem.

Any help would be appreciated. I hope I described the problem detailed enough. If not, I would be glad to provide more information.

EDIT: I try mysqld restart and I get even more errors:

  • are you able to locate your my.cnf file? – s2t2 Feb 26 '14 at 22:30
  • No, I can not locate the my.cnf file in any folder. – David S. Feb 27 '14 at 15:58
  • have you tried uninstalling mysql via brew? http://stackoverflow.com/questions/4359131/brew-install-mysql-on-mac-os if so, you might be able to then use brew to re-install it – s2t2 Feb 27 '14 at 22:43
  • I've tried uninstalling it multiple times. It always comes to the same error. – David S. Feb 28 '14 at 10:38
  • i was just able to resolve my problem by removing an extraneous my.cnf file from my /etc dir. see http://stackoverflow.com/questions/2482234/how-to-know-mysql-my-cnf-location – s2t2 Feb 28 '14 at 20:37

This mainly looks like a permissions problem. These two lines are critical:

2014-02-25 12:35:54 34599 [ERROR] InnoDB: ./ibdata1 can't be opened in read-write mode
2014-02-25 12:35:54 34599 [ERROR] InnoDB: The system tablespace must be writable!

I can see you set permissions on the mysql files, but you should probably check ownership too. With homebrew it's generally safe to do sudo chown -R david:staff /usr/local as well as sudo chmod u+rwX /usr/local (a better option than 0755 permissions), and mysql under homebrew should be running as you.

While you're installing, I'd recommend you look into using the Percona server version of MySQL which is also available in homebrew as percona-server. You could also consider MariaDB - they are both drop-in replacements for vanilla MySQL and have some advantages.

We met the same problem yesterday. My mistake was executing

sudo launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

at the first time, but forgot to unload it. Several clues:

  1. a process mysqld_safe runs under root
  2. a process mysql runs under _mysql
  3. they both up and down again and again.
  4. the owner of error file /usr/local/var/mysql/*.err is _mysql
  5. when run sudo launchctl list | grep mysql, a mysql service exists

The solution is simple:

sudo launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

The root reason is that, homebrew's mysql is not assumed to be run under root, at least it seems.

Maybe it is not the same problem as yours, but I wish it would help.
