Finding the connection information for an RDS for MySQL DB instance

The connection information for a DB instance includes its endpoint, port, and a valid database user, such as the master user. For example, suppose that an endpoint value is mydb.123456789012.us-east-1.rds.amazonaws.com. In this case, the port value is 3306, and the database user is admin. Given this information, you specify the following values in a connection string:

  • For host or host name or DNS name, specify mydb.123456789012.us-east-1.rds.amazonaws.com.

  • For port, specify 3306.

  • For user, specify admin.

To connect to a DB instance, use any client for the MySQL DB engine. For example, you might use the MySQL command-line client or MySQL Workbench.

To find the connection information for a DB instance, you can use the AWS Management Console, the AWS CLI describe-db-instances command, or the Amazon RDS API DescribeDBInstances operation to list its details.

To find the connection information for a DB instance in the AWS Management Console

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. In the navigation pane, choose Databases to display a list of your DB instances.

  3. Choose the name of the MySQL DB instance to display its details.

  4. On the Connectivity & security tab, copy the endpoint. Also, note the port number. You need both the endpoint and the port number to connect to the DB instance.

    The endpoint and port of a DB instance in the Amazon RDS console.

  5. If you need to find the master user name, choose the Configuration tab and view the Master username value.

To find the connection information for a MySQL DB instance by using the AWS CLI, run the describe-db-instances command. In the call, query for the DB instance ID, endpoint, port, and master user name.

For Linux, macOS, or Unix:

aws rds describe-db-instances \
  --filters "Name=engine,Values=mysql" \
  --query "*[].[DBInstanceIdentifier,Endpoint.Address,Endpoint.Port,MasterUsername]"

For Windows:

aws rds describe-db-instances ^
  --filters "Name=engine,Values=mysql" ^
  --query "*[].[DBInstanceIdentifier,Endpoint.Address,Endpoint.Port,MasterUsername]"

Your output should be similar to the following.

[
    [
        "mydb1",
        "mydb1.123456789012.us-east-1.rds.amazonaws.com",
        3306,
        "admin"
    ],
    [
        "mydb2",
        "mydb2.123456789012.us-east-1.rds.amazonaws.com",
        3306,
        "admin"
    ]
]

To find the connection information for a DB instance by using the Amazon RDS API, call the DescribeDBInstances operation. In the output, find the values for the endpoint address, endpoint port, and master user name.
