You can establish a connection using any MySQL-compatible client program. This topic describes how to connect to a MySQL instance by using a client program.
Background information
RDS for MySQL supports multiple types of addresses. We recommend that you use private addresses for connection. Before you use a local application to access MySQL instances, you should first request a public address for MySQL instances.
The default port of MySQL instances is 3306. You can modify the connection address prefix and port of a MySQL instance. If necessary, refer to Modifying the connection address prefix and port.
Procedure
Complete the following operations based on the location where the client program is deployed.
- Deploy the client on an ECS instance (recommend)
- Make sure that ECS instances and MySQL instances are in the same VPC network.
- Get the private IPv4 address of ECS instances.
- Add the private IPv4 address of ECS instances to the allowlist of MySQL instances. For specific procedures, refer to Setting allowlist.
- Complete the required configuration in the client application and connect to the instance.
- Deploy the client locally
- Apply for a public network address for the MySQL instance. For more information about how to apply for a public address, refer to Enabling or disabling public network access.
- Obtain the public IPv4 address of your local device.
- Add the public IPv4 address of the local device to the IP allowlists of the MySQL instance. For specific procedures, refer to Setting allowlist.
- Complete the required configuration in the client application and connect to the instance.
