安装依赖
yum install gcc pcre-static pcre-devel -y

2、make TARGET=linux2628
3、make install
4、mkdir -p /etc/haproxy
5、ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy
(安装完的可之执行文件在/usr/local/sbin/haproxy，需要创建一个软连接到/usr/sbin/haproxy，因为启动脚本默认使用/usr/sbin/haproxy这个位置)
6、cp /opt/haproxy/haproxy-1.9.8/examples/haproxy.init /etc/init.d/haproxy
(把启动文件拷贝到init.d目录下)
