mac brew install mysql ‘/tmp/mysql.sock’ (2) [How to Solve]

the reason for the error is very simple: MySQL should be used instead of MySQL when starting the command server

mac brew install mysql

Install MySQL with homebrew on Mac to perfectly solve error 2002 (HY000):

Can’t connect to local MySQL server through socket ‘/tmp/mysql.Sock ‘(2) error

1. Start the command mysql server

the startup method of using MySQL command directly is wrong

This problem occurs when you directly call the MySQL command. It is said on the Internet that it is because of MySQL Caused by CNF configuration file.

the correct startup method is mysql server

➜  support-files mysql

➜  support-files pwd
/opt/homebrew/opt/mysql/support-files
