apache [error] (OS 10061)解决方案

大湖之子

　　使用apache+mongrel_cluster发布redmine大，是apache的error.log文件过一段时间就汇报一个10061错误：
Apache log代码

　　比较郁闷了，查了一下资料，需要修改apache的配置文件，不采用loopback方式，具体修改如下：
　　第一步、修改mongrel_cluster.yml文件，将address修改为IP地址，如下图：
　　---
address: 192.168.3.239 //原先未127.0.0.1或localhost  
log_file: D:/redmine-1.1.3/log/mongrel.log
port: "3000"
cwd: D:/redmine-1.1.3
environment: production
pid_file: D:/redmine-1.1.3/tmp/pids/mongrel.pid
servers: 4
　　第二步、修改apache的conf文件，将其中的balance
　　ProxyRequests Off   
     
    BalancerMember http://192.168.3.239:3000  //原先未http://localhost:3000
    BalancerMember http://192.168.3.239:3001  //原先未http://localhost:3001
    BalancerMember http://192.168.3.239:3002  //原先未http://localhost:3002
    BalancerMember http://192.168.3.239:3003  //原先未http://localhost:3003

SetEnvIfNoCase Request_URI "BitTorrent" BT
     
    ServerName localhost
    DocumentRoot "d:/redmine-1.1.3/public/"
    ProxyPass /images !
    ProxyPass /javascripts !
    ProxyPass /stylesheets !
    ProxyPass /server-status !
    ProxyPass / balancer://myCluster/
    ProxyPreserveHost on   

　　第三步、重启mongrel_cluster
　　第四步、重启apache，上午10点修改，观察到下午2:50吗，问题一直没有出现，应该解决了
