Set Up SSH Keys

Step One—Create the RSA Key Pair

• The first step is to create the key pair on the client machine

ssh-keygen -t rsa (it will generate id_rsa and id_rsa.pub inside ~/.ssh directory )

OR

ssh-keygen -f user (it will generate user and user.pub inside the directory where you have executed the command )

Store the Keys and Passphrase in your desired location

store the .pub (public key ) n private key in your desired location

Copy the Public Key

login to your server using ssh and go to cd ~/.ssh/ if doesn't exist .ssh dir inside ~ then create one and create a authorized_keys file and paste the .pub file content.
