【WEB】Web性能压力测试工具
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

[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 ctags
- install: 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

Benchmarking: GET http://www.baidu.com/
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 http://www.joedog.org/pub/siege/siege-latest.tar.gz
解压： tar -zxvf siege-latest.tar.gz
cd siege-*.*.*
./configure --prefix=/usr/local/siege --mandir=/usr/local/man --with-ssl=/usr/local/ssl
mkdir -p /usr/local/siege/etc
mkdir -p /usr/local/siege/var
make
make install
查看配置文件
/usr/local/siege/bin/siege -Csiege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 www.baidu.com
50个用户 重复100次 发送GET参数
/usr/local/siege/bin/siege -c 50 -r 100 http://www.baidu.com/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 “https://www.abc.com/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 “https://www.abc.com/a.php POST < /root/ab_test/post.xml”
另外还有挺多参数
