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 ~]# 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。
