尝试了所有的命令行，还是不行。我要做的事情有:

mv /usr/local/Cellar/mysql/5.7.16/bin/mysqld /usr/local/Cellar/mysql/5.7.16/bin/mysqld.bak
mysql.server stop

这种方法有效，mysqld进程消失了。但是/var/log/system.log有很多垃圾:

Jul  9 14:10:54 xxx com.apple.xpc.launchd[1] (homebrew.mxcl.mysql[78049]): Service exited with abnormal code: 1
Jul  9 14:10:54 xxx com.apple.xpc.launchd[1] (homebrew.mxcl.mysql): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

好吧，如果所有这些都失败了，您可以采取无情的方法，手动杀死运行MySQL的进程。

也就是说,

ps -Af

列出所有进程，然后执行“kill <pid>”，其中<pid>是MySQL守护进程(mysqld)的进程id。

我在macports上安装了mysql5和mysql55。对我来说，这里提到的文件位于以下位置:

(mysql55-server) / opt /地方/ etc / LaunchDaemons / org.macports.mysql55-server / org.macports.mysql55-server.plist

(mysql5) / opt / local / etc / LaunchDaemons - org . macports mysql5 mysql5 - org . macports。plist

所以停下来是这样做的:

mysql55-server:

sudo launchctl unload -w /opt/local/etc/LaunchDaemons/org.macports.mysql55-server/org.macports.mysql55-server.plist

mysql5:

sudo launchctl unload -w /opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist 

您可以检查服务是否仍在运行:

ps ax | grep mysql

此外，你可以在我的案例中查看日志文件:

mysql55-server

sudo tail -n 100 /opt/local/var/db/mysql55/<MyName>-MacBook-Pro.local.err
...
130213 08:56:41 mysqld_safe mysqld from pid file /opt/local/var/db/mysql55/<MyName>-MacBook-Pro.local.pid ended

mysql5:

sudo tail -n 100 /opt/local/var/db/mysql5/<MyName>-MacBook-Pro.local.err
...
130213 09:23:57  mysqld ended

显然你想:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop

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

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
