Connect to localhost
I was trying to connect to mysql on docker using localhost, but got an error.
$ mysql -u root -h localhost
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Connect to 127.0.0.1
Using 127.0.0.1 instead of localhost solves the issue.
$ mysql -u root -h 127.0.0.1

Why?
when you connect to “localhost” the socket connector is used, but when you connect to “127.0.0.1” the TCP/IP connector is used.
