Hi,
I am using pm2 for hosting nodejs webapps and pm2 has cluster mode for creating multiple instances

How should I put my multiple instances in nginx for load balancing and reverse proxy operation as for now my pm2 enabled nodejs works on locahost:3000 port 80 and i have configure my nginx on port 81
Please suggest !

put nginx on port 80 and your node application on say 8000, then in the upstream project block, use

server 127.0.0.1:8000

pm2 will automatically balance the load between the cluster.

Why doesn't nginx load balance to my box with an express app running ?

ngnix is running on box1 under 55.55.55.5
express app is running on box2 uder 55.55.55.2:3000

When I'm going to 55.55.55.5 I'm getting this - Welcome to nginx! bla bla bla

upstream project {
  server 55.55.55.2:3000
}

server {
  listen 80;

  location / {
    proxy_pass http://project;
  }
}

SOLVED

The issue was because of default conf file in sites-available, just delete or rename it and you good to go.

if something is wrong try like this

location ~ ^/views/((css|js|gif|jpe?g|png).*)$ {
expires 168h;

}

can you please write this code in apache also.
