haproxy 超时机制

 

<pre name="code" class="python">option  redispatch  option redispatch   是否允许重新分配在session 失败后  
      
option abortonclose 丢弃由于客户端等待时间过长而关闭连接但仍在haproxy等待队列中的请求  
  
  
    option abortonclose  
  
    #当服务器负载很高的时候，自动结束掉当前队列处理比较久的链接    
  
defaults  
        log     global  
        mode    http  
        option  httplog  
        option  dontlognull  
        retries 3  
        option  redispatch  
        option  abortonclose  
        maxconn 65535  
        timeout connect 5000  
        timeout client  50000  
        timeout server 50000  
  
        timeout check   5s  
        stats   refresh 30s  
  
  
timeout http request ：在客户端建立连接但不请求数据时，关闭客户端连接  
timeout queue ：等待最大时长  
timeout connect： 定义haproxy将客户端请求转发至后端服务器所等待的超时时长  
timeout client：客户端非活动状态的超时时长  
timeout server：客户端与服务器端建立连接后，等待服务器端的超时时长，  
timeout http-keep-alive ：定义保持连接的超时时长  
timeout check：健康状态监测时的超时时间，过短会误判，过长资源消耗  
  
  
  
client_timeout 是 app 连接 haproxy的时间  
server_timeout 是haproxy 连接后端的时间.  
  
目前发现 超时后,前台一个点击 haproxy 会收到两个相同的请求,原因待查明。  
  
  
  
  
  
  
设置 5秒超时时:  
     timeout connect 5000  
        timeout client  50000  
        timeout server 50000  
  
        timeout check   5s  
        stats   refresh 30s

相同请求发了2次  
  
设置  
  
        timeout connect 500000  
        timeout client  500000  
        timeout server 500000
