This minHour 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
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.
