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.基于源地址访问控制案例实战
1>.编写haproxy的配置文件
[[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 defaults option http-keep-alive option forwardfor option redispatch option abortonclose maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms errorloc 503 http://node107.yinzhengjie.org.cn/monitor/503.html 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 acl hacker_deny src 172.30.1.254 http-request deny if hacker_deny http-request allow default_backend backup_web backend web_server server web01 172.30.1.104:80 check inter 3000 fall 3 rise 5 backup server web02 172.30.1.106:80 check inter 3000 fall 3 rise 5 server web03 172.30.1.107:80 check inter 3000 fall 3 rise 5 backend backup_web server web01 172.30.1.108:80 check inter 3000 fall 3 rise 5 [[email protected] ~]# [[email protected] ~]# systemctl restart haproxy [[email protected] ~]#
2>.查看haproxy的监听端口和进程信息
[[email protected] ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 172.30.1.102:80 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 172.30.1.102:8888 *:* LISTEN 0 128 :::22 :::* [[email protected] ~]# [[email protected] ~]# ps -ef | grep haproxy | grep -v grep root 20704 1 0 20:25 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /yinzhengjie/softwares/haproxy/haproxy.pid haproxy 20708 20704 0 20:25 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /yinzhengjie/softwares/haproxy/haproxy.pid haproxy 20709 20704 0 20:25 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /yinzhengjie/softwares/haproxy/haproxy.pid [[email protected] ~]# [[email protected] ~]#
3>.查看haproxy的状态页(http://node102.yinzhengjie.org.cn:8888/haproxy-status)
三.验证haproxy的配置
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
