This wikiHow will teach you how to enable SSH in CentOS 7. Since SSH comes pre-installed along with CentOS, you'll just need to run a command to enable it. Once you've enabled SSH, make sure port 22 is open on your router to allow incoming connections.
Steps
-
1Enter the following code into your command-line utility:
sudo yum -y install openssh-server openssh-clients.[1]- This code installs the appropriate SSH server and client type.
-
2Enter the following code:
sudo systemctl start sshd.- With this active, the SSH service will start and will listen continuously for actions from clients, like connection requests.

3Enter the following code:
sudo systemctl status sshd.- You should see an "active" status. If you don't, you may need to restart your system and try again.
- To stop SSH, enter
systemctl stop sshdand you'll see an "inactive" tag. - If you want SSH to automatically start whenever you reboot the system, enter:
sudo systemctl enable sshd. Change "enable" to "disable" if you want to cancel the automatic setting.
