对网站进行AB测试—笔记

Tuesday, May 25, 2010

1, 使用默认安装的ab工具并发稍微一大就出“apr_socket_recv: Connection reset by peer
(104)” 错误, google了一把找了到一篇博客《apache ab stress tool “apr_socket_recv:
Connection reset by peer (104)”
的處理》
,根据blog,下载最新的apache
http server :http://httpd.apache.org/download.cgi#apache22,
修改support下面的ab.c源代码, 大概在 line 1369, 修改成

1368                 return;
1369             } else {
1370                 //apr_err("apr_socket_recv", status);
1371                 bad++;
1372                 close_connection(c);
1373                 return;
1374             }

然后编译安装 然后到安装目录下运行ab:

./ab -n 1000 -c 1000 -C auth_token=92dd856aacc414faf0dc5ed0bb61f5c3badd233e http://xxx.com/

正常了

2, 但是

./ab -n 10000 -c 2000 -C auth_token=92dd856aacc414faf0dc5ed0bb61f5c3badd233e  http://xxx.com/

这时候出错了,“socket: Too many open files (24)” , 这个好办, 改一下系统的打开文件数的上限
$ sudo su
ulimit -n 30000
./ab -n 10000 -c 2000 -C auth_token=92dd856aacc414faf0dc5ed0bb61f5c3badd233e http://xxx.com/

ok了!~
