webbench最多可以模擬3萬個并發連接去測試網站的負載能力，個人感覺要比Apache自帶的ab壓力測試工具好用，安裝使用也特別方便，并且非常小。

一，環境：linux

二，安裝方式：編譯安裝

?具體步驟如下：

?1，安裝編譯工具：

1	[root@zabbix?install]#?yum?install?ctags?wget?make?apr*?autoconf?automake?gcc?gcc-c++

?2，下載該軟件包

1 2 3 4 5 6 7 8 9

[root@zabbix?install]#?wget?http://home.tiscali.cz/cz210552/distfiles/webbench-1.5.tar.gz? --2016-07-06?19:01:29--??http://home.tiscali.cz/cz210552/distfiles/webbench-1.5.tar.gz Resolving?home.tiscali.cz...?82.208.6.172 Connecting?to?home.tiscali.cz|82.208.6.172|:80...?connected.

?3，編譯安裝

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

[root@zabbix?install]#?tar?zxvf?webbench-1.5.tar.gz? webbench-1.5/ webbench-1.5/webbench.1 webbench-1.5/socket.c webbench-1.5/webbench.c webbench-1.5/Makefile webbench-1.5/debian/ webbench-1.5/debian/rules webbench-1.5/debian/dirs webbench-1.5/debian/copyright webbench-1.5/debian/control webbench-1.5/debian/changelog webbench-1.5/COPYRIGHT webbench-1.5/ChangeLog [root@zabbix?install]#?cd?webbench-1.5 [root@zabbix?webbench-1.5]#?mkdir?/usr/local/man??????#創建該目錄否則會失敗 [root@zabbix?webbench-1.5]#?make cc?-Wall?-ggdb?-W?-O???-c?-o?webbench.o?webbench.c webbench.c:?In?function?‘alarm_handler’: webbench.c:77:?warning:?unused?parameter?‘signal’ cc?-Wall?-ggdb?-W?-O??-o?webbench?webbench.o?? ctags?*.c [root@zabbix?webbench-1.5]#?make?install 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

?4，進行壓力測試

1 2 3 4 5 6 7

[root@zabbix?webbench-1.5]#?webbench?-c?100?-t?30?http://192.168.1.245/zabbix.php?action=dashboard.view Webbench?-?Simple?Web?Benchmark?1.5 Copyright?(c)?Radim?Kolar?1997-2004,?GPL?Open?Source?Software. Benchmarking:?GET?http://192.168.1.245/zabbix.php?action=dashboard.view 100?clients,?running?30?sec. Speed=1676?pages/min,?355898?bytes/sec. Requests:?838?susceed,?0?failed.

說明：-c 100:表示同時產生100個并發連接

? ?-t 30:表示持續30秒

備注：webbench最大可以模擬30000個并發連接

實戰：方法是使用Web Bench進行并發壓力測試，選擇的頁面是http://192.168.1.245/zabbix.php?action=dashboard.view并發請求開始5個，每次循環增加5個進入下輪的循環，每一輪循環持續180s，到達最大200個并發時結束。這樣就可以持續做2小時的測試。

for n in `seq 5 5 50` ; do echo -n $n " " ; webbench -c $n -t 60 ?http://192.168.1.245/zabbix.php?action=dashboard.view ?1>/dev/null | grep Speed | awk '{print $1}' | awk -F= '{print $2}' ; echo ; done

1 2 3 4 5 6 7 8 9 10 11
