Suppose that I had set the root password before with ssh
key. Hereinafter, I want to let the root without password. Is there a way to do that?

In Ubuntu the root account has no password but is locked by default, so that you can not log in as root using a password. If you paste your public key ( ~/.ssh/id_rsa.pub
) into root's authorized_keys file ( /root/.ssh/authorized_keys
) then you can log in via 'ssh' as root without needing a password.
Yes you can set the root without password to SSH login without password, but it's highly not recommended, user other user then use su to become root.
ssh
key into/root
. Would you mind to give me a little explanation on that? Thank you
