在终端中点击“brew services start mysql”即可

对我来说，这就像跑步一样简单:

/usr/local/opt/mysql/bin/mysqld_safe

而不是mysqld

这可能是因为MySQL已经安装但还没有运行。

要验证它正在运行，打开活动监视器，在“所有进程”下，搜索并验证你看到了进程“mysqld”。

你可以通过安装“MySQL.prefPane”来启动它。

在安装mysql的过程中，您可能会遇到一些问题，mysql服务可能无法运行。如果是这种情况，那么可能值得尝试以下步骤重新安装mysql，然后尝试连接。

sudo chown -R $(whoami) /usr/local/var

sudo chown -R $(whoami) /Library/Caches/Homebrew

brew uninstall mysql

brew install mysql

mysql.server start   

mysql -uroot  

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:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.26

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。
