A. Installing Apache Httpd and preparation of test data

1> Test Architecture Description

  node102.yinzhengjie.org.cn:
    Haproxy server

  node105.yinzhengjie.org.cn:
    Test server, client simulation

  node106.yinzhengjie.org.cn:     Apache httpd server   node107.yinzhengjie.org.cn:     Apache httpd server   node108.yinzhengjie.org.cn:     Apache httpd server

2> Install Apache httpd service

  This process is relatively simple, I am here to skip directly, and can refer to my previous notes: https: //www.cnblogs.com/yinzhengjie/p/12114195.html

 

II. Based on the real case of the source address access control

1> write haproxy profile

[[email protected] ~]# cat /etc/haproxy/haproxy.cfg
global
    maxconn 100000
    chroot /yinzhengjie/softwares/haproxy
    stats socket /yinzhengjie/softwares/haproxy/haproxy.sock mode 600 level admin
    user haproxy
    group haproxy
    daemon
    nbproc 2
    cpu-map 1 0
    cpu-map 2 1
    nbthread 2
    pidfile /yinzhengjie/softwares/haproxy/haproxy.pid
    log 127.0.0.1 local5 info

3> View haproxy status page (http://node102.yinzhengjie.org.cn:8888/haproxy-status)

 

III. Configuration verification haproxy

1>.IP地址为"172.30.1.254"的客户端访问haproxy的地址:"http://node102.yinzhengjie.org.cn",如下图所示    

2>.使用"node105.yinzhengjie.org.cn"节点访问haproxy的地址:"http://node102.yinzhengjie.org.cn",如下图所示
