Generate ssh file

To log in to a server with ssh keys you need to first generate a key file using ssh-keygen and get two files id_rsa and id_rsa.pub. The .pub file is a public key, you need to put it into .ssh/authorized_keys file.

Upload it to the server

You can paste it yourself or use ssh-copy-id -i key_file user@host to upload it automatically.

Or you can do it manually:

  1. login to your server and go to ~/.ssh dir
  2. vi authorized_keys
  3. Paste the content of id_rsa.pub into it
