Accessing AWS instance over SSH using .pem file
In this post, we will show how you can ssh to your AWS Linux instance from your machine’s terminal. We have attempted to access Linux AWS instance from our Ubuntu laptop,
In below command,
- /home/devlab/Downloads/ – directory where we download the .pem file from AWS dashboard
- my-key-pair.pem – The generated .pem file when you created AWS instance
- ec2-user => The username of your AWS instance, you can find the users at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/managing-users.html
- public DNS name / public IP – you can get the this from your AWS instance dashboard.
ssh -i /home/devlab/Downloads/my-key-pair.pem ec2-user@my-instance-public-dns-name
Or you can use your public IP as well,
ssh -i /home/devlab/Downloads/my-key-pair.pem ec2-user@my-instance-public-ip
