Reverse Proxy NGINX

Introduction

Proxying is typically used to distribute the load among several servers, seamlessly show content from different websites, or pass requests for processing to application servers over protocols other than HTTP.

Passing a Request to a Proxied Server

location /some/path/ {
    proxy_pass http://www.example.com/link/;
}

location ~ \.php {
    proxy_pass http://127.0.0.1:8000;
}

Passing Request Headers

location /some/path/ {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_pass http://localhost:8000;
}

location /some/path/ {
    proxy_set_header Accept-Encoding "";
    proxy_pass http://localhost:8000;
}

Configuring Buffers

location /some/path/ {
    proxy_buffers 16 4k;
    proxy_buffer_size 2k;
    proxy_pass http://localhost:8000;
}

location /some/path/ {
    proxy_buffering off;
    proxy_pass http://localhost:8000;
}

Choosing an Outgoing IP Address

location /app1/ {
    proxy_bind 127.0.0.1;
    proxy_pass http://example.com/app1/;
}

location /app2/ {
    proxy_bind 127.0.0.2;
    proxy_pass http://example.com/app2/;
}

location /app3/ {
    proxy_bind $server_addr;
    proxy_pass http://example.com/app3/;
}
