HttpUpstreamFairModule

= ngx_http_upstream_fair_module =

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

The upstream_fair module sends an incoming request to the least-busy backend server, rather than distributing requests round-robin.

Example:

upstream backend { server server1; server server2; fair; }

fair
syntax fair

context upstream

Enables fairness.

upstream_fair_shm_size
syntax upstream_fair_shm_size size

default upstream_fair_shm_size 32k

context main

Size of the shared memory for storing information about the busy-ness of backends. Defaults to 8 pages (so 32k on most systems).

= Installation = This module is not distributed with the Nginx source. You can browse its git repository, or download the tar ball.

After extracting, add the following option to your Nginx ./configure command:

--add-module=path/to/upstream_fair/directory

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