Configuration for nginx in front of node

nginx_config_1.txt

# Example 1
# -------------------------------------------------
# nginx config file for nodejs
#
# you can put nginx in front of node for two good reasons:
# 1) To take some of the load off nodejs for serving
#    anything static.
# 2) To run multiple nodjs sites on one server
#    domain1:80 -|->nginx-|-> nodejs:3000
#    domain2:80 -|        |-> nodejs:4000
# -------------------------------------------------

# Node pet_project on Port 3000

upstream pet_project {
  server localhost:3000;
}
 
server {
  listen 80;
  server_name pet-project.myhost;
 
  location / {
    alias /opt/demo/pet-project/public/;
    try_files $uri @pet-project;
  }
 
  location @pet-project {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $proxy_host;
    proxy_set_header X-NginX-Proxy true;
 
    proxy_pass http://pet_project;
  }
