upstream project {
  server 22.22.22.2:3000;
  server 22.22.22.3:3000;
  server 22.22.22.5:3000;

server {
  listen 80;

  location / {

  location ~* \.(css|js|gif|jpe?g|png)$ {
    expires 168h;
    
  }
  location /api {
    expires 10m;
  }
}

where can I read what does ~* means? I read that ~ is to put a PCRE in front of that, but I don't understand the * (star space).

Does this still need app.use(express.static('public/dir')); to work please?

@molinto, yes still you will be needed!

I didnt get how same port can be acquired by 3 diff servers? is upstream block containing 3 different IPs or 3 different servers are running on same port? Please help me i m totally confued.

Ok. I got the answer what actual that means. Thanks a lot for the article and video.

@juanpastas read more about the ~* http://nginx.org/en/docs/http/ngx_http_core_module.html#location

@juanpastas The ~* means start case-insensitive regex, while ~ means case-sensitive regex.

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.
