SSH Server CentOS 9 Installation – Step-by-step

Getting-Started

3. 3. Launching SSH Server

   Finally, Start SSH Server
   With:

   sudo systemctl start sshd

   To enable it at Boot:

   sudo systemctl enable sshd

   In case, to Stop it:

   sudo systemctl stop sshd

To Enable Remote Access from a Client.
Output the Client Key:

cat ~/.ssh/id_rsa.pub

Select & Ctrl+Shift+c to Copy on Terminal.
Then Append it to the Server authorized_keys File:
(Here for simplicity with the nano Editor, but you can just use Anyone.)

sudo nano ~/.ssh/authorized_keys

Ctrl+x to Save & Exit from nano Editor.
Last, Test your SSH Connection locally:

ssh `whoami`@localhost

The `whoami` Command just to Output your Username.
Remotely instead:

ssh `whoami`@[MYSERVERIP]

Replace “[MYSERVERIP]” with that you can find in: How to Check IP Guide.
Access with your User Password.
To Quit:

exit
