NGINX Demo

Manually?

We COULD manually complete each of the following configuration changes to set up our web server...

curl -L https://github.com/do-community/html_demo_site/archive/refs/heads/main.zip -o html_demo.zip

sudo apt install unzip

unzip html_demo.zip

ls -la html_demo_site-main

mkdir files

nano files/nginx.conf.j2

server {
  listen 80;

  root {{ document_root }}/{{ app_root }};
  index index.html index.htm;

  server_name {{ server_name }};
  
  location / {
   default_type "text/html";
   try_files $uri.html $uri $uri/ =404;
  }
}

Or using a playbook

Take a look at the provided playbook for this nginx demo. We can use built in modules to complete the installation and copy the configuration! This ensure a consistant, repeatable deployment with ease!

nano playbook.yml

AND! we can accomodate various states accross multiple servers by including them in our inventory

ansible-playbook -i inventory playbook.yml -u itstudent -K

Test your web servers

On your local machine you should be able to hit each server in your browser: i.e. https://localhost:8023
