HAProxy-安装及基础配置

三、HAProxy安装及基础配置

介绍HAProxy的基础安装及基础配置

3.1 源码包安装

官方提供了Ubuntu和Debian的包，没有Centos的包

ubuntu 安装

apt-get install --no-install-recommends software-properties-common 
#--no-install-recommends 参数来避免安装非必须的文件，从而减小镜像的体积
add-apt-repository ppa:vbernat/haproxy-2.6
apt-get install haproxy=2.6.\*

#安装常用软件包
apt-get install --no-install-recommends software-properties-common -y
#--no-install-recommends 参数来避免安装非必须的文件，从而减小镜像的体积

 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 2.6.

Centos安装

在centos系统上通过yum、编译等多种安装方式。
默认yum源
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。

# yum install haproxy -y
#验证haproxy版本
# haproxy -v
HA-Proxy version 1.5.18 2016/05/10

3.2 编译安装HAProxy

编译安装HAProxy 2.0 LTS版本，源码包下载地址：http://www.haproxy.org/download/

3.2.1 解决lua环境

HAProxy支持基于lua实现功能扩展，lua是一种小巧的脚本语言，于1993年由巴西里约热内卢天主教大学（Pontiﬁcal Catholic University of Rio de Janeiro）里的一个研究小组开发，其设计目的是为了嵌入应用程序中，从而为应用程序提供灵活的扩展和定制功能。

Lua 官网：www.lua.org

Lua应用场景
游戏开发
独立应用脚本
Web应用脚本
扩展和数据库插件，如MySQL Proxy
安全系统，如入侵检测系统

Centos 环境：
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，因此需要编译安装较新版本的lua环境，然后才能编译安装HAProxy，过程如下：

The HAProxy documentation has been split into a number of different files for
ease of use.

Please refer to the following files depending on what you're looking for :

  - INSTALL for instructions on how to build and install HAProxy
  - BRANCHES to understand the project's life cycle and what version to use
  - LICENSE for the project's license
  - CONTRIBUTING for the process to follow to submit contributions

The more detailed documentation is located into the doc/ directory :

  - doc/intro.txt for a quick introduction on HAProxy
  - doc/configuration.txt for the configuration's reference manual
  - doc/lua.txt for the Lua's reference manual
  - doc/SPOE.txt for how to use the SPOE engine
  - doc/network-namespaces.txt for how to use network namespaces under Linux
  - doc/management.txt for the management guide
  - doc/regression-testing.txt for how to use the regression testing suite
  - doc/peers.txt for the peers protocol reference
  - doc/coding-style.txt for how to adopt HAProxy's coding style
  - doc/internals for developer-specific documentation (not all up to date)
