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-
documentation, and the version
haproxy(1)
manual page.
