apache2.2+Tomcat+jk 集群

是二子啊 2013-08-22 04:32:21

单个Tomcat6.0 测试并发数500通过。
用Apache做了集群。并发果断降到100.应该是配置出问题。我想知道配置哪里出问题了。
在线等。。。
求大神指点~~~~~~~~~~~~~~


环境：
Win7 64位 8G内存，4核i5处理器。Mysql5.6，项目ＳＳＨ２


配置：
httpd-mpm.conf

Windows 操作系统 使用的是 mpm_winnt，你所做的测试，毫无意义。 Linux下，要检查下你编译Apache时，选择的是 mpm_prefork 还是 mpm_worker，一般推荐后者。 —— 注：这个信息可以直接从 http://localhost/server-info 中看到，如果你开启了的话
能加下QQ说吗？1987870278 谢谢啦~

问题：什么操作系统？ 建议：开启server-status和server-info检查配置情况和运行情况 <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 管理机IP </Location> <Location /server-info> SetHandler server-info Order deny,allow Deny from all Allow from 管理机IP </Location>
服务器是Linux 64位 我拿本机测试的，本机是Win7

如果是单纯的用jk连接tomcat的话可以考虑下面的配置： <IfModule mpm_prefork_module> ServerLimit 2048 StartServers 128 MinSpareServers 128 MaxSpareServers 256 MaxClients 2048 MaxRequestsPerChild 0 </IfModule> apache的httpd.conf配置
