在我的 Mac 上，我用自制软件安装了 MariaDB；但是，当我尝试登录时，出现以下错误。

ERROR 2002 (HY000): 无法通过套接字 '/tmp/mysql.sock' 连接到本地 MySQL 服务器 (2)

我搜索了 mysql.sock。没有 /tmp/mysql.sock 也没有 /var/lib/mysql.sock。它不存在。

我想我已经阅读了关于这个主题的所有其他帖子，并尝试了很多方法来让它发挥作用；但是，无济于事。所以，我发布了安装、重启和登录的三个步骤，希望有人能看到我在安装过程中遗漏的东西。

（第 1 步）这是我使用 brew 安装 MariaDB 的输出

brew install mariadb

Try 'mysqld --help' if you have problems with paths.  Using
--general-log gives you a log in /opt/homebrew/var/mysql that may be helpful.

Warning: The post-install step did not complete successfully
You can try again using:
  brew postinstall mariadb
==> Caveats
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

MySQL is configured to only allow connections from localhost by default

To restart mariadb after an upgrade:
  brew services restart mariadb
Or, if you don't want/need a background service you can just run:
  /opt/homebrew/opt/mariadb/bin/mysqld_safe --datadir=/opt/homebrew/var/mysql
==> Summary
  /opt/homebrew/Cellar/mariadb/10.6.4: 898 files, 170.1MB
==> Running `brew cleanup mariadb`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

（2）安装后我重启服务器

 $ brew services restart mariadb
Stopping `mariadb`... (might take a while)
==> Successfully stopped `mariadb` (label: homebrew.mxcl.mariadb)
==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)

(3) 我尝试登录数据库

mysql -uroot -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local server through socket '/tmp/mysql.sock' (2)

任何建议将不胜感激。
