Nginx性能测试工具之webbench
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
# ./webbench -help
