Explain the difference between the Apache rcapache2 command restart and reload options.
What will be an ideal response?
The restart option stops the apache2 service and then restarts it. If the service is already stopped, this option is the same as using the start option. The reload option restarts the apache2 service safely because it ensures that all forked processes have finished before shutting down the service.
