在OSX雪豹

launchctl unload /System/Library/LaunchDaemons/org.mysql.mysqld.plist

如果你正在使用自制啤酒，你可以使用

brew services restart mysql
brew services start mysql
brew services stop mysql

获取可用服务的列表

brew services list

Try

sudo <path to mysql>/support-files/mysql.server start
sudo <path to mysql>/support-files/mysql.server stop

其他的尝试:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop<br>
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart

然而，我发现第二个选项只有在.plist已经加载了以下内容时才能工作(OS X 10.6, MySQL 5.1.50):

sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysqld.plist

PS:我还发现我需要卸载.plist来获得一个不相关的MAMP-MySQL安装，以正确启动/停止。运行之后，MAMP-MySQL启动正常:

sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysqld.plist

你可以使用命令"mysqladmin shutdown"

sudo /usr/local/mysql/support-files / mysql。服务器停止
