Linux SSH Password-free login

Work often to log on the Linux host too many, each time the password is too troublesome, with a few password-free login, each time can not remember, this time to write down to forget.

First use the Ssh-keygen tool on your own machine to create the key, as follows

ssh-keygen-t rsa

To automatically generate ~/.ssh/authorized_keys files on the target server using the Ssh-copy-id command

ssh-copy-id-i ~/.ssh/id_rsa.<目标机器>
