To enable the SSH service on CentOS 7, you can follow these steps:

  1. Access the console of the CentOS 7 server or use other remote access methods such as IPMI or iLO.
  2. Open the terminal or command line interface.
  3. install the openssh-server package using yum
  4. Start the sshd service in systemd.
  5. Start the sshd service at boot.
  6. Please connect to the server using SSH with the following command: ssh username@server_ip

Please note, if your server is running firewall software (such as Firewalld or iptables), you will also need to configure the firewall to allow SSH connections. By default, Firewalld on CentOS 7 is already configured to allow SSH connections, but you can use the following command to confirm:

firewall-cmd --list-services

If the “ssh” service is not listed, you can use the following command to add it:

firewall-cmd --add-service=ssh --permanent
firewall-cmd --reload

After completing these steps, you should be able to successfully connect to the CentOS 7 server via SSH.
