如何在 macOS 上通过 brew 安装时卸载 MySQL 5.6？
How to uninstall MySQL 5.6 when installed by brew on macOS?
已通过发出以下命令安装 MySQL：
$ brew install mysql56
$ brew services start mysql@5.6
现在我无法访问它：
$ mysql -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
想卸载它并尝试了以下方法：
brew remove mysql
brew cleanup
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySql*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
(Restart computer)
现在工作。
当我再次安装它并且运行:
brew intall mysql56
brew services start mysql@5.6
显示：
Service `mysql@5.6` already started, use `brew services restart mysql@5.6` to restart.
但是我在进程列表中找不到。
到 Stack Overflow。
我会回答这个问题，但是请务必check for existing questions，因为已经有人问过了。
试试这个
brew uninstall --force mysql
或来自Google First result being from CoderWall
找到任何 运行 个实例
ps -ax | grep mysql | grep -v grep
# OR for only the running `PID`
ps -ef | grep mysql | grep -v grep | awk '{print }'
# OR this If you have this on your machine, I recommend using
pgrep -f mysql
如果运行终止进程
kill 24024824082408 # change this number to what was returned in the grep
保存您的数据库数据
这会将您的 MySQL 数据文件夹保存到桌面的文件夹 mysqldata 中。
# I backup my data from mysql to my desktop
mkdir ~/Desktop/mysqldata/
# data
cp -r /usr/local/mysql/data ~/Desktop/mysqldata
保存您的 MySQL Workbench 迁移数据。
# MySQL workbench active sessions including the unsaved query windows
cp -r ~/Library/Application\ Support/MySQL/Workbench/sql_* ~/Desktop/mysqldata
# data this is a log containing queries that were logged at some point, more of a `just in case`
cp ~/Library/Application\ Support/MySQL/Workbench/log/sql_actions_unconnected.log ~/Desktop/mysqldata/sql_actions_unconnected.sql
# data of user snippets as people forget about this.
cp /Users/`id -un`/Library/Application\ Support/MySQL/Workbench/snippets/User\ Snippets.txt ~/Desktop/mysqldata/UserSnippets.txt
删除和清理
brew remove mysql
brew cleanup
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
编辑（如果适用）vi /etc/hostconfig 并删除行 MYSQLCOM=-YES-
如果要确保任何 MySQL 个进程被终止，请重新启动计算机
尝试 运行 mysql，应该不行。
不要担心某些 rm 的失败，它们根本不存在。
希望这对您有所帮助，祝您有愉快的一天！
