Jan 02, 2020 I have used /.ssh/idrsa.pub because that is the default location for the public ssh key. If you have it at some other location, you should use that in the above command. Method 2: Manually copy the public ssh key to the server.
You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account. When generating SSH keys yourself under Linux, you can use the ssh-keygen command. To do so follow these steps: Open up the Terminal; Type in the following command.

How do I install my SSH public key ~/.ssh/id_rsa.pub onto a remote Linux and UNIX server automatically from Linux workstation or Apple OS X laptop without using scp and/or copy & paste method?
You need to use the ssh-copy-id script that uses ssh to log into a remote machine using a login password. The syntax is as follows:

Install ssh-copy-id on a OS X Unix systems

Type the following command:

Sample outputs:

Step # 1: Create the Keys

Type the following ssh-keygen command to generates, manages and converts authentication keys for your workstation / laptop:
ssh-keygen
Make sure you protect keys with the passphrase.

Step # 2: Install the public key

Install key in a remote server called www-03.nixcraft.in, enter:
ssh-copy-id -i ~/.ssh/id_rsa.pub username@www-03.nixcraft.in

Note: If ssh-copy-id command not found on your system, try the following commands to append/install the public key on remote host:
ssh username@www-03.nixcraft.in 'umask 077; mkdir .ssh' cat $HOME/.ssh/id_rsa.pub | ssh username@www-03.nixcraft.in 'cat >> .ssh/authorized_keys'

Step #3: Use keychain for password less login

OpenSSH offers RSA and DSA authentication to remote systems without supplying a password. keychain is a special bash script designed to make key-based authentication incredibly convenient and flexible (see how to install keychain script on unix). Add following lines to your ~/.bash_profile or shell login file:
