ngx_http_upstream_hash_module

-

This module is not distributed with the Nginx source. Installation instructions are below.

The upstream_hash module provides simple upstream load distribution by hashing a configurable variable (e.g., the request URI, incoming HTTP headers, or some combination). Example usage: 

upstream backend {
-    server server1;
-    server server2;
-    hash   $request_uri;
-}
-

Here, Nginx will choose server1 or server2 by hashing the request URI ($request_uri).

-

Directives

-

-

hash

-

syntax hash $variable

context upstream

Enables upstream hashing of $variable.

When present, the "server" directives cannot take any arguments ("weight", "max_fails", etc.).

-

hash_again

-

syntax hash_again number

default 0

context upstream

Number of times to rehash the value and choose a different server if the backend connection fails. Increase this number to provide high availability.

-

Installation

-

This module is not distributed with the Nginx source. You can download the request_hash module here: nginx_upstream_hash-0.3.tar.gz

After extracting, you will need to patch the latest Nginx source (0.7.11 as of this writing). Run patch like this: 

    cd nginx-0.7.11
-    patch -p0 < /path/to/upstream/hash/directory/nginx.patch
-

Then add the following option to your Nginx ./configure command: 

    --add-module=path/to/upstream/hash/directory
-

Then "make" and "make install" as usual.

-

The hash algorithm

-

As of 0.3, the hash algorithm and the failover algorithm use a CRC-32 computation compatible with PECL Memcache.

-

Changes

-
  • * 0.3: Feature: PECL Memcache compatibility. Change: Removed "hash_method" directive.

-

Bugs

-

Send bug reports to Evan Miller.
