本文介绍了在Ubuntu 11.10上使用Webbench进行Nginx服务器的压力测试过程。通过逐步安装Webbench并进行不同并发数的测试，得出服务器在不同并发情况下的性能表现，包括成功的请求次数、响应速度和失败情况，为选择LAMP或LNMP提供依据。

最近app需要搭建后台，故此研究一下，靠谱的后台服务器..网传nginx 能达到的并发数量比apache 高. LAMP or LNMP ？根据需求测试结果来进行选择。

首先是安装LNMP测试完后再测试 LAMP，网上很多，我这里就介绍一下自己在ubuntu 安装webbench(压力测试工具)http://home.tiscali.cz/~cz210552/webbench.html

1.下载webbench

miechal@miechal-ubuntu:~$ wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz

2.解压安装webbench

miechal@miechal-ubuntu:~/Downloads$ tar -zxvf webbench-1.5.tar.gz

miechal@miechal-ubuntu:~/Downloads$ cd webbench-1.5/
miechal@miechal-ubuntu:~/Downloads/webbench-1.5$ make && make install

可能会遇到权限问题和ctags命令解析不了问题：

make: [tags] Error 127 (ignored)
install -s webbench /usr/local/bin
install: cannot create regular file `/usr/local/bin/webbench': Permission denied

解决方法：

（1）.修改相应目录的权限

miechal@miechal-ubuntu:/usr$ sudo chmod a+w -R local/

(2) 安装 ctags命令

miechal@miechal-ubuntu:~/Downloads/webbench-1.5$ sudo apt-get install ctags

(3)安装make

miechal@miechal-ubuntu:~/Downloads/webbench-1.5$ sudo make && make install

3.接下来可以测试了

条件1：模拟200个客户端请求.
