Let's start up the igweb web server instance:
$ cd $IGWEB_APP_ROOT$ ./igweb
Figure 11.4 shows a screenshot of IGWEB running on a standalone server instance at the address http://igweb.kamesh.com:
When we hit the Ctrl + C key combination to exit the igweb program, our web server instance comes to a grinding halt since it's been running in the foreground. NGINX will return the 502 Bad Gateway server error for any client request. We need a way to daemonize igweb so that it runs in the background.
