Mac Brew Uninstall MySql

如果你brew install mysql 之后出現問題要卸載：

brew remove mysql

brew cleanup

launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

rm ~/Library/LaunchAgents/com.mysql.mysqld.plist

sudo rm -rf /usr/local/var/mysql

然后重新開始

1. installed mysql with brew install mysql

2. ran the commands brew suggested:

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

3. Start mysql with mysql.server command, to be able to log on it

4. Used the alternate security script:

   /usr/local/Cellar/mysql/5.5.10/bin/mysql_secure_installation
   

5. Followed the launchctl section from the brew package script output

6. Boom.
