1、安装pcre
apt-get update
(apt-get install openssl libssl-dev ==>可能需要安装的依赖包)
apt-get install libpcre3 libpcre3-dev
#yum -y groupinstall "Development Tools" // 安装gcc等linux开发工具
2、解压
# tar zcvf haproxy-1.5.8.tar.gz
# cd haproxy-1.5.8
# make TARGET=linux26 PREFIX=/usr/local/haproxy #将haproxy安装到/usr/local/haproxy
# make install PREFIX=/usr/local/haproxy
cd /usr/local/haproxy
vim haproxy.conf
# this config needs haproxy-1.1.28 or haproxy-1.2.1
