My First Load Balancer

I write this post as a requirement for my tenth PPW lab assignment. I would like to share my experience on using nginx for the first time. The project was limited to localhost. To start it off, i created a basic application using django, to display the port it is ran on. Then i used the command “manage.py runserver 8000” and “manage.py runserver 9000” to simulate 2 servers running the application. Afterwards i configure my nginx.conf file to be

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

events {     worker_connections 1024; } http{     upstream localhost {         server 127.0.0.1:8000;         server 127.0.0.1:9000;     }       server {         listen 80;         server_name localhost;         location / {             proxy_pass http://localhost;         }     } }

Then i ran nginx and reload the configuration to apply the new file. Afterwards i opened port 80 through my browser and the app would alternatively display 8000 and 9000 each time i opened a new instance of the localhost:80. And there you have it, a simple example for nginx in localhost
