Nginx性能測試工具之webbench

     在apache中有自帶的ab指令可以測試服務的壓力,而nginx沒有自帶的指令,必須要采用第三方軟體來測試,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者和運維人員必須的,可以很清晰地看清伺服器能接受多大壓力.注:本人是在虛拟機上做測試.

1.下載下傳webbench軟體和安裝

[root@centos179min ~]# wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz

[root@centos179min ~]# tar xvf webbench-1.5.tar.gz  -C /usr/local/

[root@centos179min ~]# cd /usr/local/webbench-1.5/

[root@centos179min webbench-1.5]# make

[root@centos179min webbench-1.5]# make install

2.指令詳解
