apache反向代理实现负载均衡,编译mod_proxy模块

      #ProxyPass /hs/ balancer://mycluster/
 
   #stickysession session的性质,是否具有粘性
   #nofailover=On不支持会话复制
   #lbmethod 负载均衡的算法,lbmethod可能的取值有：
   #lbmethod=byrequests 按照请求次数均衡(默认)
   #lbmethod=bytraffic 按照流量均衡
   #lbmethod=bybusyness 按照繁忙程度均衡(总是分配给活跃请求数最少的服务器)
   #maxattempts=1 apache在放弃服务前,尝试的次数
 
   ProxyPass /hs/ balancer://mycluster/ stickysession=STICK_PORT_TOKEN nofailover=On lbmethod=byrequests maxattempts=1
   ProxyPassReverse /hs balancer://mycluster/
 
   #调整由反向代理服务器发送的HTTP应答头中的URL.
   #根据代理打开 balancer://mycluster/ 模块的a.html
   #如果点击a.html页面的内部链接(绝对路径另论),需要这个设置将路径修改为代理的路径.
