Mysql 外部連線到Docker中

[soon530]

一般是用socket去連。

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

但docker是跑tcp的方式。

NAME                COMMAND                  SERVICE             STATUS              PORTS
mysql57             "docker-entrypoint.s…"   db                  running             0.0.0.0:3306->3306/tcp, 33060/tcp

指定用tcp來連線就沒問題了！

 % mysql -u root -p --protocol=tcp
Enter password:
