显然你想:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop

你可以进一步阅读《Jeez People，停止为安装RMagic而烦恼》。

对我来说，它与mysql5一起工作

sudo launchctl unload -w /Library/LaunchDaemons/org.macports.mysql5.plist
sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

如果你安装了MacPorts的MySQL 5包:

sudo launchctl  unload -w /Library/LaunchDaemons/org.macports.mysql.plist 

Or

sudo launchctl  unload -w /Library/LaunchDaemons/org.macports.mysql5-devel.plist 

如果您安装了mysql5-devel包。

有不同的情况取决于你是用官方二进制安装程序安装MySQL，使用MacPorts，还是使用Homebrew:

家酿

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

MacPorts

sudo port load mysql57-server
sudo port unload mysql57-server

注意:重启后会持续。

二进制安装程序

sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart

最新的OSX(10.8)和mysql 5.6，文件是在Launch Daemons和com.oracle.oss.mysql.mysqld.plist。它在系统选项下显示一个选项，通常在列表的底部。所以进入系统设置，点击Mysql，并从选项框中关闭它。https://dev.mysql.com/doc/refman/5.6/en/osx-installation-launchd.html

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
