What command is used to check the status of Apache?

The command "systemctl status httpd" is used to check the status of the Apache HTTP server on systems that use systemd as their init system. This command provides detailed information about the Apache service, including whether it is active (running) or inactive (stopped), the current status, and other relevant logs or messages. It allows system administrators to monitor the health of the service easily and manage it accordingly.

In many modern Linux distributions, particularly those based on Red Hat, Fedora, and Ubuntu, "systemctl" is the standard tool for managing system services. It not only allows checking the status of the service but also enables starting, stopping, and restarting the service if needed. This makes it the most appropriate choice for checking the status of Apache in an environment where systemd is utilized.

Other commands may provide functionality related to managing Apache, but they do not serve the same purpose in the context of checking the service status in a systemd-managed environment.
