我有一个服务器托pipe多个网站，但在逻辑上看起来像子目录。 例：
- http://XXX/Site1 - http://XXX/Site2 如何configurationHAProxy的运行状况检查来检查每个“子站点”？
使用多个后端，每个检查1个网站。 使用ACL来执行内容切换，即select后端根据HTTP请求的某些属性来路由请求，在这种情况下是URLpath。
例：
global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 user haproxy group haproxy daemon defaults log global mode http option httplog option dontlognull retries 3 option redispatch maxconn 2000 timeout connect 5000 timeout client 50000 timeout server 50000 frontend 1.2.3.4-80 bind 1.2.3.4:80 mode http option http-server-close option logasap acl url_site1 url_beg /Site1 acl url_site2 url_beg /Site2 use_backend site1 if url_site1 use_backend site2 if url_site2 backend site1 mode http balance roundrobin option httpchk HEAD /Site1 HTTP/1.1\r\nHost:\ XXX server srv1 1.1.1.1:80 check server srv2 2.2.2.2:80 check backend site2 mode http balance roundrobin option httpchk HEAD /Site2 HTTP/1.1\r\nHost:\ XXX server srv1 1.1.1.1:80 check server srv2 2.2.2.2:80 check
您可以在Haproxy中启用HTTP检查来检查HTTP服务器
