In the world of web engineering and development, developing web-based applications always need a web application server where all web pages are accommodated. Depending on what web technology as well as scripting language is used at server-side, commands to run a web server is various. For example, there are some web servers such as Apache (currently known as Apache2), Nginx, NodeJS etc.
However, if you want to start instantly a web server regardless of mess settings up, Python could help you create a simple server based on builtin HTTP Server. This feature could turn any directory in your system into your web server directory.
Practically speaking this is very useful to share files inside your local network. Implementing this tiny but hugely useful HTTP server is very simple, its just a single line command.
Open up a terminal and type of the following code snippets:
In Python 2.x
cd /home/your_web_directory python -m SimpleHTTPServer [port_number]
In Python 3.x
cd /home/your_web_directory python -m http.server [port_number]
That’s it! Now your http server will start in port 8000 if [port_number] is not precise. You will get the messages looking like the following image:
Now open a browser and type one of the following addresses:
http://192.168.1.2:8000 http://220.127.116.11:8000 http://localhost:8080
If you have a specific port indicating the running code snippet, replace 8000 with this port number.
If your directory is containing an index.html or default.html, you could see its content rendered on your web browser. Otherwise, your directory would be browsed. To stop the web server, you just need to hit Ctrl-C from the keyboard.
Note also that this should also work on Windows or Cygwin.
