Step 4: Connect to a DB Instance Through a Public Network

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

Preparations

  1. Bind an EIP to the target DB instance and configure security group rules.
    1. Bind an EIP to the target DB instance.

      For details about how to bind an EIP, see section Step 2: Bind an EIP.

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

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

      For details about how to configure a security group rule, see section Step 3: Configure Security Group Rules.

    4. Run the ping command to check the connectivity between the local device and the DB instance.
  2. Use a database client to connect to the target DB instance.

    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?
