nginx multiple static content servers on subdomains

Question

I have one server with nginx-frontend and Apache-backend.

I need to set up nginx to return images from the other two servers randomly like

• http://example.com/images/*.jpg -> http://i1.example.com/*.jpg
• http://example.com/images/*.jpg -> http://i2.example.com/*.jpg

image folder is the same on both servers.

I would be grateful for any advice.

Answer 1

You would use the upstream directive to do this.

Sample below, you would add in the rest of your server config etc

upstream backend {
    server i1.example.com;
    server i2.example.com;
}

location /images/ {
    proxy_pass http://backend/;
    #rest of config
}

It is possible to do more then 50/50 split by using the weight function but without it the default weight is used which is 1.
