Eight, configure Linux

① the previous version, step five above does not have the OPENSSH key format option, you need to upload the generated public key to the Linux server and follow the command below.

1. Create a directory Mkdir/root/.ssh

2. Modify the properties chmod 700/root/.ssh

3. Create a file Touch/root/.ssh/authorized_keys

4. Convert key Ssh-keygen-i-F identity.pub >>/root/.ssh/authorized_keys

5. Modify the Properties chmod 600/root/.ssh/authorized_keys

6. Restart Service/etc/init.d/sshd Restart

② This case does not need to convert the key, directly copy the contents of the Identity.pub to/root/.ssh/authorized_keys
