使用ab对网站进行压力测试,开始设置并发500,可以正常使用,当设置并发为1000,则报错:
apr_socket_recv: Connection reset by peer (104)
改服务端apache的maxclients参数,调大最大打开文件数,都不解决问题,最后才发现是因为ab的源码对ab的并发有限制,修改源码重新编译apache:
修改源码support目录下的ab.c文件，大概在1369行,修改为:
return;
} else {
//apr_err("apr_socket_recv", status);
bad++;
close_connection(c);
return;
}
最后贴上ab的参数使用:
/usr/local/apache2/bin/ab -c 3000 -n 5000 http://192.168.1.43/index.html

ab -n 200 -c 10 -T 'application/json' -p post.json http://127.0.0.1:8002/webapi/
执行此命令目录下，放置post.json文件：
{
"jsonrpc": "2.0",
"method": "test_method",
"params": [1442885518, 1442892718,"testDomain_80"],
"id": "1"

Downloading Apache for Windows
The Apache HTTP Server Project itself does not provide binary releases of software, only source code. Individual committers may provide binary packages as a convenience, but it is not a release deliverable.
If you cannot compile the Apache HTTP Server yourself, you can obtain a binary package from numerous binary distributions available on the Internet.
Popular options for deploying Apache httpd, and, optionally, PHP and MySQL, on Microsoft Windows, include:
http://www.apachehaus.com/cgi-bin/download.plx
http://www.apachelounge.com/download/

ab -n 100 -c 10 http://www.baidu.com/s
-n 表示请求数，-c 表示并发数.
s为path，表示指定测试地址，不指定可能会报”ab: invalid url” 错误.
另外还有-t 表示多少s内并发和请求
测试出来的数据如下:

ab是apache自带的网站压力测试工具。
使用起来非常的简单和方便。
不仅仅是可以apache服务器进行网站访问压力测试，还可以对其他类型的服务器进行压力测试。
比如nginx,tomcat，IIS等
首先当然是下载安装了。
在这里只讲window下在下载安装
官方下载地址：,(https://www.apachehaus.com/cgi-bin/download.plx)
下载完成后解压
我就直接解压到d盘的apacheab中去了
修改解压根目录下的conf/httpd.conf文件的端口配置，默认是80端口，应该是被占用了，无法安装，可以自行修改为其他，我在这里修改为8088端口
然后输入命令安装：
httpd -k install
第一次安装错误是因为端口没有改，被占用了，应该是被iis占用的。
