nginx壓力測試工具

在apache中有自帶的ab命令可以測試服務的壓力,而nginx沒有自帶的命令,必須要採用第三方軟件來測試,今天就簡單介紹一下webbench對nginx的壓力測試,壓力測試是對系統管理員和運維人員必須的,可以很清晰地看清服務器能接受多大壓力.注:本人是在虛擬機上做測試.

 

1.下載webbench軟件和安裝

# 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.命令詳解

# ./webbench -help

3.測試網站壓力
