<p>This article describes how to create a whitelist.</p> <p><span style="font-size:18px"><strong>Overview</strong></span></p> <p>After you successfully create an RDS MySQL instance, you can perform operations by logging in to the RDS MySQL database. RDS MySQL service of Ping An Cloud supports open source MySQL protocol. Users can connect to an RDS MySQL instance with any general MySQL client. For the purpose of security, Ping An Cloud currently does not support RDS MySQL instances to be connected via the Internet. They need to be connected via ECS of Ping An Cloud.</p> <p>It is not allowed to access an RDS MySQL instance by default. Therefore, you need to create a whitelist in the RDS MySQL console to allow an ECS to access the RDS MySQL instance. Using a whitelist in a correct way will improve the access security of RDS MySQL service.</p> <p>A general instance, remote disaster recovery instance, and read-only instance need to create whitelists respectively.</p> <p><span style="font-size:18px"><strong>Usage Limitation</strong></span></p> <p>RDS MySQL instances currently cannot be accessed by BMS in East China region.</p> <p><span style="font-size:18px"><strong>Prerequisites</strong></span></p> <ol> <li>You have successfully created an instance.
