Removing MySQL from OSX Lion
Recently I’ve had to remove a version of MySQL 5.5 from my Macbook so that I could go back to a 5.1 version. However it appears that there isn’t an automatic way to remove and install an older version. A few google searches revealed a bulk of the removal process, but additional searching revealed a few more steps.
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /var/db/receipts/com.mysql.*
# Edit the following file, removing the line `MYSQLCOM=-YES-`.
# you may need sudo for write privileges to edit the file
# TIP: when using vim, use `dd` to delete the line and then `:wq` to save
# the file
sudo vim /etc/hostconfig # remove the line MYSQLCOM=-YES-
