ERROR 2002 (HY000): Can't connect to MySQL server on '172.18.0.4' (115)

求解答？？？？在线等谢谢，可进行远程协调

Answer 1

Maybe the root is not allowed to connect mysql server from a remoting host. I advise you to create a new user instead of root.

create user 'joey'@'%' identified by 'yourpassword';
grant all privileges on yourdb.* to 'joey'@'%'

you can replace '%' with your host（if not, connecting mysql server from every remoting host is allowed）

Answer 2

要检查下 mysql服务是否开了远程权限
