5.6. Accessing the Presto Cluster

Connect to your Presto Cluster via SSH

1. Preliminary Steps

In order to access your Presto cluster, you must obtain the public DNS name of your cluster and the file name of your .pem file.

To locate the public DNS:

  • CloudFormation Console: Navigate to the CloudFormation Console under “Management Tools” within the Services menu.

  • Outputs: Select your “Stack Name” and click the associated tab labeled “Outputs”.

  • Public SSH Access: Find and copy the “Public Presto SSH” value.

2. Open a Terminal Window
Open a terminal window to begin a command line.
3. Establish a Connection

To establish a connection to the master node, issue a command in your terminal. Using the example below, replace ec2-##-###-###-##.regioncode.compute.amazonaws.com with the public DNS name of your cluster and replace mykeypair.pem with the location and file name of your .pem file.

Reference the following example:

ssh ec2-user@ec2-##-###-###-##.regioncode.compute.amazonaws.com -i ~/.ssh/mykeypair.pem
4. Close
When you have finished working with your Presto cluster, type the exit command to close the SSH connection.
