 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.

<h7 id=2>Centos7.6 Yum安裝1.8.14</h7>

默認(rèn)情況centos7中的包都是較老的haproxy是1.5.18-9.el7的，不太滿足需求，此時(shí)我們可以基于第三方安裝包yum安裝
https://pkgs.org/download/haproxy 該網(wǎng)址el7最新rpm包更新至1.8.14

一般需要一個(gè)依賴倉(cāng)庫(kù)包和haproxy.rpm的安裝包

下載安裝包

 wget https://centos.pkgs.org/7/cheese-x86_64/haproxy-1.8.14-1.el7.x86_64.rpm.html

下載依賴包

 weget https://centos.pkgs.org/7/cheese-x86_64/cheese-release-7-1.noarch.rpm.html

安裝對(duì)應(yīng)的包

#rpm -ivh cheese-release-7-1.noarch.rpm

#yum install haproxy-1.8.14-1.el7.x86_64.rpm -y

編譯安裝HAProxy 2.0 LTS版本，更多源碼包官網(wǎng)下載地址：http://www.haproxy.org/download/

HAProxy 支持基于lua實(shí)現(xiàn)功能擴(kuò)展，為應(yīng)用程序提供靈活的擴(kuò)展和定制功能,由于centos自帶的lua版本比較低并不符合HAProxy要求的lua最低版本(5.3)的要求，因此編譯時(shí)需要安裝該包,lua官方下載地址

yun安裝編譯環(huán)境

yum install libtermcap-devel ncurses-devel libevent-devel readline-devel wget make gcc-y

下載lua5.3.5
