CentOS6.7 configure the HAProxy proxy transit configuration

HAProxy is a free, fast, and reliable proxy solution that supports high availability and server load balancer. It is also suitable for proxies for TCP and HTTP-based applications. For some websites with high load, HAProxy is particularly suitable. HAProxy supports tens of thousands of concurrent connections. It is easy to configure and can easily integrate into our existing application architecture.

Next, we will install and configure HAProxy on CentOS 6.7.
