HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware. Its mode of operation makes its integration into existing architectures very easy and riskless, while still offering the possibility not to expose fragile web servers to the Net.
This PPA contains packages for HAProxy 2.0.

默认情况centos7中的包都是较老的haproxy是1.5.18-9.el7的，不太满足需求，此时我们可以基于第三方安装包yum安装
https://pkgs.org/download/haproxy 该网址el7最新rpm包更新至1.8.14
一般需要一个依赖仓库包和haproxy.rpm的安装包
下载安装包
wget https://centos.pkgs.org/7/cheese-x86_64/haproxy-1.8.14-1.el7.x86_64.rpm.html下载依赖包
weget https://centos.pkgs.org/7/cheese-x86_64/cheese-release-7-1.noarch.rpm.html安装对应的包
#rpm -ivh cheese-release-7-1.noarch.rpm#yum install haproxy-1.8.14-1.el7.x86_64.rpm -y#验证haproxy版本
# haproxy -v

HAProxy 支持基于lua实现功能扩展，为应用程序提供灵活的扩展和定制功能,由于centos自带的lua版本比较低并不符合HAProxy要求的lua最低版本(5.3)的要求，因此编译时需要安装该包,lua官方下载地址
