If you just want to have an HTTP server running, what is the easiest way? So far, the answer for me is this command:
python -m SimpleHTTPServer 8080
It will serve the content in the current path. If you know a better answer, please let me know.
Update [2015-11-17]: Another way is to use PHP’s built-in server, as suggested by Subin Siby:
php -S 0.0.0.0:8080
