Command:

Explanation:

• sudo: Runs the command with superuser privileges, which is typically required to manage system services.
• systemctl: The system and service manager in modern Linux distributions (e.g., CentOS, Ubuntu) that controls system services.
• restart: Tells systemctl to stop and then start the specified service, effectively restarting it.
• {service_name}: The name of the service you want to restart (e.g., nginx, apache2, ssh).

Example:

To restart the nginx service, the command would be:

Result:

This command will restart the nginx service, stopping it and then starting it again. Any changes made to the service configuration will be applied after the restart.

Additional Notes:

• To check the status of a service after restarting, you can use:
  bash

  Копировать код

  sudo systemctl status {service_name}


  For example:

  bash

  Копировать код

  sudo systemctl status nginx

• If you want to reload the service without completely restarting it (for example, to apply configuration changes), you can use:
  bash

  Копировать код

  sudo systemctl reload {service_name}
