下载安装haproxy
tar -zxvf haproxy-1.4.24.tar.gz
cd haproxy-1.4.24
uname -r #查看下linux内核
make TARGET=linux2632 PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy
2.创建chroot所需目录
mkdir /var/haproxy
3.创建haproxy主配置文件
global
log 127.0.0.1 local3
chroot /var/haproxy
pidfile /var/haproxy/haproxy.pid
maxconn 4000
user haproxy
group haproxy
daemon
nbproc 1
stats socket /var/haproxy/stats
defaults
mode http
log global

因为haproxy本来就有主配置文件在/etc/haproxy/haproxy.cfg，所以我们要把自己弄的主配置文件替换掉原本haproxy自己本身的主配置文件，
cp /etc/haproxy/haproxy.cfg /etc/haproxy/haproxy.cfg.bak
cp /etc/haproxy.cfg /etc/haproxy/haproxy.cfg
然后重启haproxy服务
service haproxy restart
4.创建haproxy用户和组
useradd -s /sbin/nologin haproxy
5.修改日志配置文件
vim /etc/rsyslog.conf # 最下面添加这三行
$ModLoad imudp
$UDPServerRun 514
local3.* /var/log/haproxy.log
6.重启rsyslog
service rsyslog restart
7.启动haproxy服务
haproxy -f /etc/haproxy.cfg
echo”/usr/local/sbin/haproxy -f /etc/haproxy.cfg start " >> etc/rc.d/rc.local
8.在浏览器输入http://192.168.20.137 和http://192.168.20.140 来确认网址是否能正确访问
9.浏览器输入web_proxy server端的ip看是否轮询 web1 2.
10.用web_proxy 192.168.20.112:8000/admin?stats 去访问浏览器看是否打开图形界面
