远程连接到基于aws-windows实例的MySQL数据库

Question

1. I have launched an AWS EC2 Windows_Server-2016 instance.
2. Since this server is windows based ,I can successfully connect to it using remote desktop connection by entering the username, password and a .ppk file.
3. I have installed MySQL server on the instance and created a user that is allowed to login with any ip ie by providing the '%' sign.

4. Here's what my AWS instance security group looks like :

5. I have tried connecting to the MySQL server using SQLYOG using 2 different scenarios :

   1. Tried connecting by using the aws public ipv4 address as a host field and using mysql username & password
   2. Tried connecting by creating an SSH connection ie providing server username/password and .ppk file in SSH connection panel & then providing mysql host/username and localhost in mysql connection panel

   None of the methods used allows me to connect.I try same procedure with a linux based server and can connect successfully. Please let me know where am I going wrong while using a windows based MySQL hosting.

MySQL has an extra level of IP protection for remote clients. You have to GRANT access to the remote ip (your house of office) to be able to connect. As root, you have to do :

GRANT ALL ON <db>.* TO '<username>'@'<remote ip>' IDENTIFIED BY '<remote_password>';

Where is the DB you are trying to connect to etc.
