How to Enable SSH in CentOS 7
How to Enable SSH in CentOS 7
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.
Things You Should Know
  • Enter this code into your command-line utility:
  • sudo yum -y install openssh-server openssh-clients
  • sudo systemctl start sshd
  • sudo systemctl status sshd .
  • You should now see an "active" status.

Enter the following code into your command-line utility: sudo yum -y install openssh-server openssh-clients. This code installs the appropriate SSH server and client type.

Enter 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.

Enter 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 sshd and 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.
