  haproxy(3)Upgrade haproxy to 1.4.25 and Proxy RabbitMQ Cluster

1. Install the latest Version
Prepare the latest Package
>wget http://haproxy.1wt.eu/download/1.4/src/haproxy-1.4.25.tar.gz
Unzip the file and Move to the working directory.
>make TARGET=generic ARCH=x86_64 USE_PCRE=1
>make install DESTDIR='/Users/carl/tool/haproxy-1.4.25' PREFIX=''

>sudo ln -s /Users/carl/tool/haproxy-1.4.25 /opt/haproxy-1.4.25

Add that sbin path to my system.
export PATH=/opt/haproxy/sbin:$PATH

Installation is success.
