Connect To Amazon AWS EC2 Instance From a CentOS / RHEL Using SSH Client

by

To connect to an Amazon AWS EC2 instance from a CentOS or Red Hat Enterprise Linux (RHEL) system using an SSH client, follow these steps:

  1. Verify that you have the ssh client installed on your local system:
which ssh
  1. Obtain the public DNS name or IP address of the EC2 instance that you want to connect to. You can find this information in the Amazon EC2 console.
  2. Open a terminal and run the following command, replacing user with the appropriate user name for your EC2 instance and public_dns_name with the public DNS name or IP address of your instance:
ssh user@public_dns_name
  1. You may be prompted to add the EC2 instance’s host key to your local known_hosts file. Type yes to continue.
  2. If you have set up key-based authentication, you should be logged in to the EC2 instance. If you are prompted for a password, enter the password for the specified user.

Once you are logged in to the EC2 instance, you can run commands and interact with the instance as if you were logged in locally. To exit the SSH session, type exit or press Ctrl + D.
