MySQL open remote access to root, change root password

1.mysql-server only allow native (localhost, 127.0.0.1) to connect access for security reasons. This is not a problem for the site architecture of Web-server and Mysql-server on the same server. However, as the site traffic increases, the late server architecture may place web-server and mysql-server on separate servers for greater performance, at which point Mysql-server is modified to allow web-server remote connections.

2. Do not log on to the server every time to add the modified table, as long as the graphical interface can be remotely managed.

We can modify the following steps as follows:
1, login mysql-server to connect to local Mysql (only local connection is allowed by default)

2. Modify Mysql-server User Configuration
