17.1 About HAProxy

HAProxy is an application layer (Layer 7) load balancing and high availability solution that you can use to implement a reverse proxy for HTTP and TCP-based Internet services.

The configuration file for the haproxy daemon is /etc/haproxy/haproxy.cfg. This file must be present on each server on which you configure HAProxy for load balancing or high availability.

For more information, see http://www.haproxy.org/#docs, the /usr/share/doc/haproxy-version documentation, and the haproxy(1) manual page.
