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
 
 
 

      option                  httplog
 
 
 

      option                  dontlognull
 
 
 

      option http-server-close
 
 
 

      option                  forwardfor
 
 
 

      option                  redispatch
 
 
 

      retries                 3
 
 
 

      timeout http-request    10s
 
 
 

      timeout queue           1m
 
 
 

      timeout connect         10s
 
 
 

      timeout client          1m
 
 
 

      timeout server          1m
 
 
 

      timeout http-keep-alive 10s
 
 
 

      stats   uri             /admin?stats
 
 
 

      #stats   hide-version（隐藏版本号）
 
 
 

      timeout check           10s
 
 
 

      #balance                 source
 
 
 

      maxconn                 3000
 
 
 

  listen web_proxy 192.168.20.112:8000
 
 
 

  server web1 192.168.20.137:8000 cookie app1inst1 check inter 2000 rise 2 fall 5
 
 
 

  server web2 192.168.20.140:8000 cookie app1inst2 check inter 2000 rise 2 fall 5
 
 
 

   
 
 
 
listen admin_status
        bind *:8000
        mode  http
        stats  enable
        stats  uri /admin?status
        stats  auth yzg:yzg1314520
        stats  refresh 5
        stats  hide-version 
 

  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
