• The default working directory is ~/project
• Use the appropriate systemd commands to manage the httpd service

Example

After starting the httpd service, you should see the following output when checking the service status:

$ systemctl status httpd

 Main PID: 12345 (httpd)
   Status: "Running, listening on: port 80"
   CGroup: /system.slice/httpd.service
           ├─12345 /usr/sbin/httpd -DFOREGROUND
           ├─12346 /usr/sbin/httpd -DFOREGROUND
           └─12347 /usr/sbin/httpd -DFOREGROUND

Summary

In this challenge, you learned how to start, stop, and check the status of the httpd (Apache HTTP Server) service using systemd commands. This is an essential skill for system administrators who need to manage and maintain network services running on their Linux servers. You practiced using the systemctl command to control the httpd service, and you also learned how to write verification scripts to ensure that the service is in the expected state.
