壓力測(cè)試工具-webbench
簡述
偶然情況下看到一款性能測(cè)試工具webbench，看著挺不錯(cuò)的記錄一下安裝過程，在以后項(xiàng)目上線過程中可以壓一壓一些頁面的并發(fā)情況，對(duì)項(xiàng)目性能有個(gè)大致的了解。

原理
webbench首先fork出多個(gè)子進(jìn)程，每個(gè)子進(jìn)程都循環(huán)做web訪問測(cè)試。子進(jìn)程把訪問的結(jié)果通過pipe告訴父進(jìn)程，父進(jìn)程做最終的統(tǒng)計(jì)結(jié)果百科介紹

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 ##這一步可能遇到如下錯(cuò)誤，手動(dòng)創(chuàng)建目錄即可
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

使用
不是專業(yè)測(cè)試，再次使用此工具模擬對(duì)一個(gè)項(xiàng)目進(jìn)行壓測(cè)，使用兩個(gè)參數(shù) c 并發(fā)客戶端數(shù)，t 運(yùn)行時(shí)長，我們來對(duì)http://www.baidu.com 做壓測(cè)看測(cè)試報(bào)告內(nèi)容

執(zhí)行命令：webbench -c 10 http://www.baidu.com
命令就是用10個(gè)客戶端并發(fā)百度網(wǎng)站30秒，但是在執(zhí)行的命令報(bào)錯(cuò)了：Invalid URL syntax - hostname don't ends with '/'。解決辦法就是在url后加個(gè)“/”

執(zhí)行結(jié)果反饋內(nèi)容：
