For this you need to be have a private key it's like keyname.pem.

Open the terminal using ctrl+alt+t.

change the file permission as a 400 or 600 using command chmod 400 keyname.pem or chmod 600 keyname.pem

Open the port 22 in security group.

fire the command on terminal ssh -i keyname.pem username@ec2-X-X-X.compute-X.amazonaws.com
