2.4、ACL案例-基于后缀调度
根据用户请求的后缀，调度到不同的后端集群
用户通过.txt调度到172.16.1.7:80
用户通过.pdf调度到172.16.1.8:80
2.4.1、配置后端节点
#web1：.txt站点定义
cat /etc/nginx/conf.d/www.qingchen.com.conf
server {
listen 8080;
server_name www.qingchen.com;
root /www
location / {
index index.html
}
}
echo ".txt-->web1" > /www/web.txt
#web2：.pdf站点定义
cat /etc/nginx/conf.d/www.qingchen.com.conf
server {
listen 80;
server_name www.qingchen.com;
root /www
location / {
index index.html
}
}
echo ".pdf-->web2" > /www/web.pdf
2.4.2、配置Haproxy
frontend web
bind *:80
mode http
# acl规则
acl www_site hdr(host) -i www.qingchen.net
# acl规则-请求txt --》 www 请求 pdf --blog
acl req_txt path_end -i .txt
acl req_pdf path_end -i .pdf
# 调用
use_backend www_cluster if www_site req_txt
use_backend blog_cluster if www_site req_pdf
default_backend www_cluster
backend www_cluster
balance roundrobin
option httpchk HEAD / HTTP/1.1\r\nHost:\ www.qingchen.net
server 172.16.1.7 172.16.1.7:80 check port 80 inter 3s rise 2 fall 3
server 172.16.1.8 172.16.1.8:80 check port 80 inter 3s rise 2 fall 3
backend m_cluster
balance roundrobin
option httpchk HEAD / HTTP/1.1\r\nHost:\ www.qingchen.net
server 172.16.1.7 172.16.1.7:8080 check port 8080 inter 3s rise 2 fall 3
server 172.16.1.8 172.16.1.8:8080 check port 8080 inter 3s rise 2 fall 3
2.4.3、客户端测试
curl -HHost:www.qingchen.net http://10.0.0.5/web.pdf
curl -HHost:www.qingchen.net http://10.0.0.5/web.txt
