在我的情况下，安装完MAMP后，从终端访问mysql会给出相同的套接字错误。最后，它想要的只是重新启动，而且它正在工作。

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

执行命令:brew info mysql

按照说明做。由公式中的描述可知:

Set up databases to run AS YOUR USER ACCOUNT with:
    unset TMPDIR
    mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

To set up base tables in another folder, or use a different user to run
mysqld, view the help for mysql_install_db:
    mysql_install_db --help

and view the MySQL documentation:
  * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
  * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html

这解决了我的问题，当我重新启动mysql服务。运行:

brew services start mysql

在我的情况下，安装完MAMP后，从终端访问mysql会给出相同的套接字错误。最后，它想要的只是重新启动，而且它正在工作。

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
