Question
Help start a NodeJs project after server restart?
I am new to Nginx and Ubuntu 16.04.
I had an Nginx website up at armadasol.com with a NodeJS script. It uses a local MongoDB and PM2. I made some hard code changes on my home page and after I refreshed the website in the browser, the changes did not update. I restarted my server and now I get a 502 Bad Gateway error.
I have got the PM2 restarted.
MongoDB is restarted
I use Nginx, NVM, NodeJs, MongoDB, PM2.
My nginx.conf
server settings:
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name localhost;
root /usr/share/nginx/html;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}

Question 1) Why am I receiving a 502 error?
Question 2) How do I prevent this next time I make changes in my files?
Question 3) Is there a script anyone recommends that can restart my nodejs app when I make changes.
