　　1：解压编译安装

　　tar zxf haproxy-1.7.9.tar.gz

cd haproxy-1.7.9

uname -e

make TARGET=linux2.6 PREFIX=/usr/local/haproxy

make install PREFIX=/usr/local/haproxy

二：创建haproxy配置文件

mkdir /etc/haproxy

cd /etc/haproxy/

vi haproxy.cfg

三：配置haproxy启动脚本

cp /haproxy-1.7.9/examples/haproxy.init /etc/init.d/haproxy
cp /usr/local/haproxy/sbin/haproxy /usr/sbin/
chmod a+x /etc/init.d/haproxy

四：启动haproxy服务

/usr/local/haproxy/sbin/haproxy -f /etc/haproxy/haproxy.cfg

或

/etc/init.d/haproxy start
