二.使用内置的acl案例实战
1>.后端服务器安装及数据准备
该过程相对简单,可参考我之前的笔记:https://www.cnblogs.com/yinzhengjie/p/12153240.html
2>.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
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 php_server path_end -i .php
use_backend nginx_php if php_server
acl static_path path_beg -i /static /images /javascript
#此处我们匹配了3给ACL规则,其中包括HTTP_1.1是内置的acl,TRUE也是内置的acl,而只有static_path才是咱们自定义的ACL
use_backend apache_httpd if HTTP_1.1 TRUE static_path
default_backend backup_web
backend nginx_php
server web04 172.30.1.104:80 check inter 3000 fall 3 rise 5
backend apache_httpd
server web03 172.30.1.103:80 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服务使得配置文件生效哟~
[root@node102.yinzhengjie.org.cn ~]#
