壓力測試工具-webbench

簡述

偶然狀況下看到一款性能測試工具webbench,看着挺不錯的記錄一下安裝過程,在之後項目上線過程當中能夠壓一壓一些頁面的併發狀況,對項目性能有個大體的瞭解。node

原理

webbench首先fork出多個子進程,每一個子進程都循環作web訪問測試。子進程把訪問的結果經過pipe告訴父進程,父進程作最終的統計結果百科介紹linux

安裝過程

[root@node1 ~]# yum install -y gcc ctags
[root@node1 ~]# wget http://www.ha97.com/code/webbench-1.5.tar.gz
[root@node1 ~]# tar -xvf  webbench-1.5.tar.gz
[root@node1 data]# cd webbench-1.5
[root@node1 webbench-1.5]# make && make install    ##這一步可能遇到以下錯誤,手動建立目錄便可
cc -Wall -ggdb -W -O   -c -o webbench.o webbench.c
webbench.c: In function 鈥榓larm_handler鈥

                                           webbench.c:77: warning: unused parameter 鈥榮ignal鈥
cc -Wall -ggdb -W -O  -o webbench webbench.o  
ctags *.c
install -s webbench /usr/local/bin
install -m 644 webbench.1 /usr/local/man/man1
install: cannot create regular file `/usr/local/man/man1': No such file or directory
make: *** [install] Error 1
[root@node1 webbench-1.5]# mkdir /usr/local/man
[root@node1 webbench-1.5]# mkdir /usr/local/man/man1
[root@node1 webbench-1.5]# make &&make install
make: Nothing to be done for `all'.
install -s webbench /usr/local/bin
install -m 644 webbench.1 /usr/local/man/man1
install -d /usr/local/share/doc/webbench
install -m 644 debian/copyright /usr/local/share/doc/webbench
install -m 644 debian/changelog /usr/local/share/doc/webbench

使用說明 經過webbench --help 命令查看

[root@node1 data]# webbench --help

  -V|--version             Display program version.

使用

不是專業測試,再次使用此工具模擬對一個項目進行壓測,使用兩個參數 c 併發客戶端數,t 運行時長,咱們來對http://www.baidu.com 作壓測看測試報告內容web

執行命令:webbench -c 10 http://www.baidu.com
命令就是用10個客戶端併發百度網站30秒,可是在執行的命令報錯了:Invalid URL syntax - hostname don't ends with '/'。解決辦法就是在url後加個「/」併發

執行結果反饋內容:工具

[root@node1 data]# webbench -c 10 -t 30 http://www.baidu.com/
