VirtualBox virtual machine MySQL remote connection login 2003 Error Resolution method

Recently installed in VirtualBox Ubuntu 14, configured with a MySQL server, set the bridging network mode. When other computers are connected, they always report 2003 errors. Start thinking that localhost is not replaced by%, run the UPDATE statement to replace it, still not. It was later discovered because MySQL has a line in the default profile/etc/mysql/my.cnf:

Bind-address = 127.0.0.1

That is, the IP is bound by default, only native access. Comment out the line with # and the remote access is OK.
