To enable SSH service on CentOS, you can follow these steps:

  1. Firstly, log in to your CentOS server. You can use an SSH client or operate directly on the server.
  2. Check if the SSH service is installed. Enter the following command to check if the OpenSSH server is installed:
sudo systemctl status sshd

If the service status shows as “active (running)”, it means the SSH service is already running.

  1. If the SSH service is not installed, you can use the following command to install the OpenSSH server:
sudo yum install openssh-server
  1. After the installation is completed, you can start the SSH service using the following command:
sudo systemctl start sshd
  1. If you want the SSH service to start automatically when the system boots up, you can use the following command to set it to start at boot:
sudo systemctl enable sshd
  1. Make sure the firewall allows SSH connections. You can open the SSH port (default is 22) using the following command:
sudo firewall-cmd --zone=public --add-port=22/tcp --permanent
sudo firewall-cmd --reload

The SSH service on your CentOS server should now be up and running, allowing access through SSH connections.
