Question

I have set up a web application on I am running it on my localhost. That is - http://127.0.0.1:8000/. I have set up sub-domains as well. For example, going to http://blog.12

Answer 1

Edit the file /etc/hosts, add the following line:

127.0.0.1 example.com blog.example.com

Then try http://example.com:8000/ and http://blog.example.com:8000/

Answer 2

Must be adding to file /etc/hosts

127.0.0.1       localhost blog.localhost lvh.me blog.lvh.me

Example for Vim editor (small overview about work in Vim)

1. Run to edit file /etc/hosts:

   sudo vim /etc/hosts
   

2. In Vim press on keyboard button i to switch on edit mode

3. Add this line:

   127.0.0.1       localhost blog.localhost lvh.me blog.lvh.me
   

4. Save file:

   • Press button Esc and after press together buttons shift :

   • Now you will see line in which write x and press Enter

Thats all, blog.localhost and blog.lvh.me is already available for all ports that you are using.
