Yes, it's running:
root 25234 0.3 1.8 96528 19568 pts/0 Sl 11:46 0:00 /srv/pbx/pbxctrl --dir /srv/pbx

This page is used to test the proper operation of the Apache HTTP server after it has been installed. If you can read this page, it means that the Apache HTTP server installed at this site is working properly.
