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。

1)->首先启动SQL server 2)(如果不存在)你必须在你安装的地方创建一个'etc'目录 Mysql ->在其中创建一个名为“Mysql .sock”的文件。 3)然后执行下面的行

 ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

4)重启服务器

5)找到mysql的路径。通过在线下执行Sock '

mysql -u root -p -h 127.0.0.1 -e "select @@socket"

现在你可以看到路径->复制该路径 6)复制完成后执行以下一行

mysql -u (username) -p -S (paste the path you copied)

7)现在，它起作用了。

在我的案例中，这只是删除一个锁文件的问题。

sudo rm -f /tmp/mysql.sock.lock

下面我包括了最新的说明从brew安装mysql，以便更新搜索这个问题可以受益:

$ brew install mysql
==> Downloading https://homebrew.bintray.com/bottles/mysql-5.6.26.yosemite.bottle.1.tar.gz
######################################################################## 100.0%
==> Pouring mysql-5.6.26.yosemite.bottle.1.tar.gz

To connect:
    mysql -uroot

To have launchd start mysql at login:
  ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Or, if you don't want/need launchctl, you can just run:
  mysql.server start

在我的情况下，我现在通过launchctl load加载mysql ~/Library/LaunchAgents/homebrew.mx .mysql。Plist，然后能够启动$ mysql和我的方式。

卸载MySQL。 删除/usr/local/var/mysql/. 安装MySQL。

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)
