安装方法

查找并确定自己需要安装的版本

# 以下是显示内容

automysqlbackup                   mysql++                           [email protected]                  [email protected]           mysql-search-replace              [email protected]

安装[email protected]

brew install [email protected]

安装成功后，会看到这样的提示

==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

可以看到brew在安装的时候已经初始过mysql了(不用再像网上说的再执行mysql_install_db命令)，且当前没有密码于是我按照它的提示，执行命令：
mysql_secure_installation
按照提示设置密码即可

配置密码…

完全卸载方法

---

关闭mysql服务

先打开系统偏好设置，关闭mysql服务

执行卸载

然后依次执行下面命令：

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
vim /etc/hostconfig  (and removed the line MYSQLCOM=-YES-)
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.*

卸载检查

保险起见，命令执行完后再检查下各文件夹

• 检查/usr/local/Cellar目录是否有mysql文件，有的话删除。
• 检查/usr/local/var 里的mysql文件，有的话删除。
• 执行brew cleanup。
