webbench

原理

webbench首先fork出多个子进程，每个子进程都循环做web访问测试。子进程把访问的结果通过pipe告诉父进程，父进程做最终的统计结果（转至百度百科）

安装

[root@VM_114_93_centos local]# wget http://home.tiscali.cz/cz210552/distfiles/webbench-1.5.tar.gz[root@VM_114_93_centos local]# tar -zxvf webbench-1.5.tar.gz webbench-1.5 webbench-1.5/webbench-1.5/webbench.1webbench-1.5/socket.cwebbench-1.5/webbench.cwebbench-1.5/Makefilewebbench-1.5/debian/webbench-1.5/debian/ruleswebbench-1.5/debian/dirswebbench-1.5/debian/copyrightwebbench-1.5/debian/controlwebbench-1.5/debian/changelogwebbench-1.5/COPYRIGHTwebbench-1.5/ChangeLog[root@VM_114_93_centos local]# cd webbench-1.5/[root@VM_114_93_centos webbench-1.5]# make && make install

安装过程中报错总结

/bin/sh: ctags: command not found，解决方法：yum install ctagsinstall: cannot create regular file ‘/usr/local/man/man1’: No such file or directory 解决方法：mkdir /usr/local/man

然后在输出make && make install

使用

安装完成后输出webbench，出现help界面

[root@VM_114_93_centos webbench-1.5]# webbench webbench [option]...

使用

[root@VM_114_93_centos swoole]# webbench -c 1000 -t 10 /Webbench - Simple Web Benchmark 1.5Copyright (c) Radim Kolar 1997-, GPL Open Source Software.Benchmarking: GET /1000 clients, running 10 sec.Speed=5766 pages/min, 11568162 bytes/sec.Requests: 958 susceed, 3 failed.

速度：每秒钟响应请求数：5766 pages/min，每秒钟传输数据量11568162 bytes/sec.

返回数：958 次返回成功，3次返回失败

ab

ab（apache bench）是apache下的一个工具，主要用于对web站点做压力测试，

安装

可以值安装Apache的tools

yum -y install httpd-tools

使用

-n在测试会话中所执行的请求个数。默认时，仅执行一个请求。

-c一次产生的请求个数。默认是一次一个。

siege

安装

下载：wget /pub/siege/siege-latest.tar.gz解压： tar -zxvf siege-latest.tar.gzcd siege-*.*.*./configure --prefix=/usr/local/siege --mandir=/usr/local/man --with-ssl=/usr/local/sslmkdir -p /usr/local/siege/etcmkdir -p /usr/local/siege/varmakemake install查看配置文件/usr/local/siege/bin/siege -C

siege的使用

举例说明：

50个用户（每次并发量）重复100次 共产生 50*100 个请求

/usr/local/siege/bin/siege -c 50 -r 100

50个用户 重复100次 发送GET参数

/usr/local/siege/bin/siege -c 50 -r 100 /s?wd=siege&rsv_spt=1&issp=1&rsv_bp=0&ie=utf-8&tn=baiduhome_pg&rsv_sug3=4&rsv_sug=2&rsv_sug1=4&rsv_sug4=60

50个用户 重复100次 发送POST参数 (注意引号)

/usr/local/siege/bin/siege -c 50 -r 100 “/a.php POST name=zhangsan”

50个用户 重复100次 发送POST参数(从文件中读取)

/usr/local/siege/bin/siege -c 50 -r 100 “/a.php POST < /root/ab_test/post.xml”

另外还有挺多参数

详情请man 或 siege -h
