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 2.4.

在centos系统上通过yum、编译等多种安装方式
3.2.1 系统默认yum源
CentOS 7 默认的base仓库中包含haproxy的安装包文件，但是版本比较旧，是1.5.18的版本，距离当前版本已经有较长时间没有更新，由于版本比较旧所以有很多功能不支持，如果对功能和性能没有要求可以使用此版本，否则推荐使用新版本。
例：centos 7安装haproxy
[root@centos7 ~]# yum install haproxy -y
# 验证haproxy版本
