在做了几个小时之后，对我有用的是 进入/etc/mysql/，编辑my.cnf文件。添加以下内容

[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock

在尝试了许多解决方案之后，似乎最终成功的是通过IP连接。不再文件套接字被随机删除。

只需更新MySQL客户端配置(例如/usr/local/etc/my.cnf):

[client]
port = 3306
host=127.0.0.1
protocol=tcp

警告:此方法将删除/usr/local/var/mysql文件夹中的所有数据库

我在Homebrew上安装了MySQL，唯一解决这个问题的方法就是重新安装MySQL。

在我公司的笔记本电脑上，我没有通过Homebrew卸载MySQL的权限:

$ brew uninstall mysql --ignore-dependencies
Uninstalling /usr/local/Cellar/mysql/8.0.12... (255 files, 233.0MB)
Error: Permission denied @ dir_s_rmdir - /usr/local/Cellar/mysql/8.0.12

所以，我手动删除并重新安装MySQL:

$ sudo rm -rf /usr/local/Cellar/mysql
$ brew cleanup
$ sudo rm -rf /usr/local/var/mysql
$ brew install mysql

这奏效了!

在我的mac m1 macOS Monterey上安装MySQL后，使用brew安装MySQL，我得到了以下信息:

[System] [MY-013169] [Server] /opt/homebrew/Cellar/mysql/8.0.27_1/bin/mysqld (mysqld 8.0.27) initializing of server in progress as process 3624

[ERROR] [MY-010457] [Server] --initialize specified but the data directory has files in it. Aborting.

[ERROR] [MY-013236] [Server] The designated data directory /opt/homebrew/var/mysql/ is unusable. You can remove all files that the server added to it.

[ERROR] [MY-010119] [Server] Aborting

[System] [MY-010910] [Server] /opt/homebrew/Cellar/mysql/8.0.27_1/bin/mysqld: Shutdown complete (mysqld 8.0.27)  Homebrew.

还有这个警告:

Warning: The post-install step did not complete successfully You can
try again using:   brew postinstall mysql

之后，我尝试使用brew services启动MySQL，我得到了这个错误:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)

我设法修复它使用:

> rm -rf ~/opt/homebrew/var/mysql/
> brew postinstall mysql

现在您可以使用mysql -uroot或mysql -uroot -p连接。

只有这一点让我成功了 酿造服务启动——全部启动 (试完所有答案后)

对于我的例子，只需将host指定为127.0.0.1，而不是localhost:

$ bin/mysql -uroot -p -h127.0.0.1
Enter password:
