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

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

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》。

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

Mysql >显示变量variable_name为'%dir%';

| datadir | / opt / local / var / db / mysql5 / |

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.
