You need to generate SSH Key ( the private key )on your cpanel server and then update remote server with the authorized_keys

1. Check if .ssh folder already exist under your home directory
(/home/user-name/.shh ).
If not create a folder .ssh

# mkdir .ssh

2. Generate or create SSH key run ssh-keygen command.

# ssh-keygen -t rsa

Press enter for all the below options to save the default settings:

-> Enter file in which to save the key (/Users/exampleuser/.ssh/id_rsa)

-> Enter passphrase (empty for no passphrase)

-> Enter same passphrase again

Now you have created the key pair. You can find all the newly generated files in your .ssh folder.

# ls
id_rsa id_rsa.pub known_hosts

you need to copy the id_rsa.pub file to your remote server .ssh folder and save as file authorized_keys

/home/user-name/.ssh/

Restart sshd.

connect remote server

# ssh root@<remote server ip>
