What is a Web Server?
The Galileo, acting as a Web Server, can host a web page, this web page can be reached by opening a web browser and navigating to the IP address of the Galileo.
The Galileo will respond with the HTML you’ve created.
Galileo hosting a Web Server.
What is the Web Server used for?
The hosted web page acts as a user interface to the Galileo, this allows you to:
- Control the GPIO pins, via a web interface.
- Display the values of GPIO pins on your web page.
- Send system commands to the operating system, via a web interface.
For more information on what a Web Server is, here are some useful links:

How do we make a Web Server?
There are several ways to create a Web Server, the main 3 methods are:
- Create a Web Server using the Arduino IDE example.
- Create a Web Server using Node.js, which comes installed on the Galileo.
- Create a Web Server using Python, which may be useful if you have a lot of scripting already completed in Python.
Click on the links above to see how I’ve used these methods to create a Web Server.
Each of the above has their own benefits and drawbacks, for example, using the Arduino IDE example is the least flexible Web Server methodology – however it provides the best (in my opinion) interface to control the GPIO’s.
Hi Allyn!
I would love to know how to make a webserver using node.js or python.
I am making a workshop about this, but I need a cue to continue. I don’t need a detailed tutorial, just a few directives. Would you help me? I will share my work with you when it get ready, if you want.
Best regards
Sebastian
Hi there,
I have just seen your reply – it was caught in my spam filter (I get a lot of spam on this account 😐 ).
Do you still need help?
I have examples of Python and Node.js webservers working, I’ll try and get them pushed to my github account.
