(C++) WtUbuntu Global Wt deployment on a home server with the Ubuntu Server operating system

 

Global Wt deployment on a home server with the Ubuntu Server operating system is a type of global Wt deployment on a home server where the server has the Ubuntu Server operating system.

 

The deployment consists of the following steps:

  • Installing Ubuntu Server edition
  • Finding out your IP address
  • (when behind a router) port forwarding
  • Starting the Wt application
  • (Optional) Register a name for your IP-address

 

 

 

 

 

Installing Ubuntu Server edition

 

Install Ubuntu Server edition on the server-to-be.

 

I did so by burning a CD from the ISO image that can be downloaded from the Ubuntu Server edition homepage. During installation I kept all options at their default.

 

 

 

 

 

Finding out your IP address

 

On the server-to-be, find out its IP address. To do, there are multiple options:

 

Write down this IP address, you will need it to access your Wt application.

 

 

 

 

 

(when behind a router) port forwarding

 

When behind a router, ports 80 an 8080 need to be forwarded to the server. How to do this depends on your router. Below I show how to do it using a router called the 'KPN Experia box'

 

To set up the port forwarding with the KPN Experia box, I used the web browser Google Chrome to access this router. According to the Experia box's manual, I would need to surft to http://192.168.2.254. After doing so, the Experia login screen was shown. After submitting the correct pasword, the Experia status screen was shown. On this screen, I can see the local (useful for computers connected to the router only) IP address and the global IP address (the IP address any Internet users can access. In this example, my server is called 'bbserver' and has a local IP address of 192.168.2.3, where the global IP address is 84.85.246.65.

 

In the Experia port mapping menu, ports 80 and 8080 are routed to the local IP address of the server, in this case 192.168.2.3.

 

 

 

 

 

Starting the Wt application

 

If you haven't installed the Wt library, do so:

sudo apt-get install witty

 

Start the Wt application (in this case 'CppHelloWorldQtCreatorUbuntu'):

 

sudo ./CppHelloWtQtCreatorUbuntu --docroot . --http-address 0.0.0.0 --http-port 8080

 

After submitting your password, the server is running. From another computer it can be accessed from its global IP address with ':8080' appended. In this example, surfing to 84.85.246.65:8080 would show up the application.

 

 

 

 

 

(Optional) Register a name for your IP-address

 

An IP address is not an easy-to-remember thing. When visiting a free dynamic DNS service, for example the changeip.net page, after a free registration, a human-readable name can be coupled to the IP address. In this example, I coupled the name 'richelbilderbeek.changeip.net' to the IP address 84.85.246.65. From then on, surfing to richelbilderbeek.changeip.net:8080 will show up the application.
