一.安装Apache Httpd及准备测试数据
1>.试验架构说明
node102.yinzhengjie.org.cn:
Haproxy服务器
node105.yinzhengjie.org.cn:
测试服务器,模拟客户端
node106.yinzhengjie.org.cn:
Apache httpd服务器
node107.yinzhengjie.org.cn:
Apache httpd服务器
node108.yinzhengjie.org.cn:
Apache httpd服务器
2>.安装Apache httpd服务
此过程相对简单,我这里就直接略过了,可参考我之前的笔记:https://www.cnblogs.com/yinzhengjie/p/12114195.html
二.基于浏览器匹配制案例实战
1>.编辑haproxy的配置文件
[root@node102.yinzhengjie.org.cn ~]# 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 defaults option http-keep-alive option forwardfor option redispatch option abortonclose maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms listen status_page bind 172.30.1.102:8888 stats enable stats uri /haproxy-status stats auth admin:yinzhengjie stats realm "Welcome to the haproxy load balancer status page of YinZhengjie" stats hide-version stats admin if TRUE stats refresh 5s frontend WEB_PORT_80 bind 172.30.1.102:80 mode http #定义ACL,匹配客户端浏览器的类型 acl google_agent hdr(User-Agent) -m sub -i "Chrome" acl firefox_agent hdr(User-Agent) -m sub -i "Firefox" #调用ACL use_backend chrome_web if google_agent use_backend firefox_web if firefox_agent #如果前面的ACL都没有匹配成功就访问默认的ACL default_backend backup_web backend chrome_web server web01 172.30.1.106:80 check inter 3000 fall 3 rise 5 backend firefox_web server web02 172.30.1.107:80 check inter 3000 fall 3 rise 5 backend backup_web server web03 172.30.1.108:80 check inter 3000 fall 3 rise 5 [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# systemctl restart haproxy #别忘记重启haproxy服务,重启后可以看到如下图所示的状态页。 [root@node102.yinzhengjie.org.cn ~]#
2>.使用谷歌浏览器访问"http://node102.yinzhengjie.org.cn/"
3>.使用火狐浏览器访问"http://node102.yinzhengjie.org.cn/"
4>.使用IE浏览器访问"http://node102.yinzhengjie.org.cn/"
5>.使用curl模拟各种浏览器访问"http://node102.yinzhengjie.org.cn/"
