Secret key authentication

Putty secret key generation
Using the Putty key tool to generate the secret key automatically

Authentication method: Public private key pairing authentication pass, public key Place server, private key save well

And keep your public key in your system.
Public key creation Save path setting
Steps

1. Mkdir/root/.shh
2. chmod 700/root/.shh
3. Vim/root/.shh/authorized_keys #一定要保存正确的路径位置
4. Vim/etc/sysconfig/selinux---selinux=disabled (permanently closed) or command line directly knocking ' Setenforce 0 '

Then log in using the secret key in the Putty tool.

There must be a point to save or the next time you want to continue with manual operation

There's no clue to that box.

Actually, it's almost putty.

You need to use putty to manually load your public key into the save file.
