macos – How do you uninstall MySQL from Mac OS X?

The Question :

I accidentally installed the PowerPC version of MySQL on my Intel Mac in Snow Leopard, and it installed without a problem but of course doesn’t run properly. I just didn’t pay enough attention. Now when I try to install the correct x86 version it says that it can’t install because a newer version is already installed. A Google query led me to perform these actions/delete these files to uninstall it:

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

And finally removed the line MYSQLCOM=-YES- from /etc/hostconfig

They haven’t seemed to help at all. I am still receiving the same message about there being a newer version. I tried installing an even newer version (the current Beta) and it also gave me the same message about a newer version already being installed. I can’t uninstall it from the Prefs Pane because I never installed the PrefPane also.

The Question Comments :
  • sudo rm -rf lines with wildcards are a little irresponsible. Especially when you cast the net widely enough to delete anything starting with the letters “My” — MySQL doesn’t have exclusive ownership over the word “My” in its title.
  • I’d also suggest backing up /usr/local/mysql/data first — many people might not realize that that’s where mysql keeps its data on mac.

Aside from the long list of remove commands in your question, which seems quite comprehensive in my recent experience of exactly this issue, I found mysql.sock running in /private/var and removed that. I used

find / -name mysql -print 2> /dev/null

…to find anything that looked like a mysql directory or file and removed most of what came up (aside from Perl/Python access modules). You may also need to check that the daemon is not still running using Activity Monitor (or at the command line using ps -A). I found that mysqld was still running even after deleting the files.

It might be overkill but your MySQL command history can also be wiped from:

~/.mysql_history

You need to identify where MySQL was installed to before attempting to delete it.

I always use the Hivelogic guide to installing under Mac OS X which builds MySQL from source. When setting up the build you can specify a directory under which to install MySQL with the –prefix parameter. You should make sure the directory does not exist and attempt to install from source.

./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \
--enable-thread-safe-client --enable-local-infile --enable-shared \
--with-plugins=innobase

You should also check /var/db/receipts and remove all entries that contain com.mysql.*

Using sudo rm -rf /var/db/receipts/com.mysql.* didn’t work for me. I had to go into var/db/receipts and delete each one seperately.
