I’m looking to automate a node.js application on amazon web services. I’m using the amazon linux ami, which is based off of centos 5. Notice that amazon has switched from using para-virtualized (pv) guests to hardware virtualized machine guests (hvm).
Launch the instance and ssh in, and become root (sudo -i). Now install nginx
[ec2-user@ip-172-30-0-164 ~]$ sudo !!
sudo yum install nginx

Use `pm2 desc[ribe] <id>` to get more detailsNow let’s add the proxy info to nginx, edit /etc/nginx/nginx.conf
server {
listen 80;
#server_name localhost;
server_name your-ip-address;
root /usr/share/nginx/html;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_cache_bypass $http_upgrade;
}restart nginx
sudo service nginx restarthit the ip address with a browser and you should see “hello world”
next up is an ansible playbook to automate this process
