Connecting to a DB Instance Through a Public Network

You can connect to a DB instance through a non-SSL connection or an SSL connection. The SSL connection encrypts data and is more secure.

Prerequisites

  1. An EIP has been bound to the target DB instance and security group rules have been configured.
    1. Bind an EIP to the target DB instance.

      For details about how to bind an EIP, see section Binding an EIP.

    2. Obtain the IP address of the local device.
    3. Configure security group rules.

      Add the IP address obtained in 1.b and the instance port to the inbound rule of the security group.

      For details about how to configure a security group rule, see section Configuring Security Group Rules.

    4. Run the ping command to check the connectivity between the local device and the EIP that has been bound to the DB instance in 1.a.
  2. You have installed a database client to connect to DB instances.

    You can use a database client to connect to the target DB instance in the Linux or Windows operating system (OS).

    • In the Linux OS, you need to install a MySQL client on the ECS. It is recommended that you download a MySQL client running a version later than that of the DB instance.

      For details about how to obtain and install the MySQL client, see section How Can I Install the MySQL Client?
