在 Apache 中有自带的 ab 命令可以测试服务的压力，而 nginx 没有自带的命令，必须要采用第三方软件来测试，今天就简单介绍一下 webbench 对 nginx 的压力测试，压力测试是对系统管理员和运维人员必须的，可以很清晰地看清服务器能接受多大压力. 注: 本人是在虚拟机上做测试。
1. 下载 webbench 软件和安装
wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz
tar xvf webbench-1.5.tar.gz -C /usr/local/
cd /usr/local/webbench-1.5/
make
make install
2. 命令详解
[root@CentOS179min webbench-1.5]# ./webbench -help
webbench [option]… URL
