HAProxy的與miltiple後端

Question

我們嘗試配置兩回在HAProxy的負載均衡方案HTTPS結束。

我們試圖終止SSL，hrd_beg，...但不能預期結果 來作爲我們試圖請求被轉移到的，而不是默認後端到其他後端每個配置。

下面是我的配置文件。

global 
     log 127.0.0.1 local0 notice 
     log 127.0.0.1 local1 debug 
     maxconn 5000     # Total Max Connections. This is dependent on ulimit 
     daemon 
     quiet 
     nbproc 1      # Number of processing cores. Dual Dual-core Opteron is 4 cores for example. 
     chroot /usr/share/haproxy 
     user  haproxy 
     group  haproxy 
     #stats  socket /var/run/haproxy.stat mode 600

     option redispatch    # Enable session redistribution in case of connection failure, which is important in a HA environment 
     option tcp-smart-accept   # Performance tweak, saving one ACK packet during the accept sequence

     stats   show-node 
     stats uri  /haproxy?stats 
     stats realm  Admin\ Portal\ HAProxy\ Statistics 
     stats auth  admin:xxxx 

我的網址開頭像apxxx.domain.com和dcxxx.domain.com。

我想配置HAProxy的這樣一種方式，如果請求的是apxxx.domain.com那麼就應該去HAProxy的後端ap_bk_https並以同樣的方式，如果它是dcxxx.domain.com它應該去HAProxy的後端dc_bk_https。

您的幫助將是讚賞！

/****************************************************/ 
      ROUTING BY SUB-Domain 

    frontend http-in 
      bind *:80 
      acl app_ap hdr_end(host) -i apxxx.domain.com 
      acl app_dc hdr_end(host) -i dcxxx.domain.com 

      use_backend ap_bk_https if app_ap 
      use_backend dc_bk_https if app_dc 


Now all request from apxxx.domain.com and dcxxx.domain.com will be redirected to your respected backends.

     Basically what you want is to route by domain name. 
     Here's an example which does exactly what you want. Have a look at it. Its simple .
