下載了 Nginx For Win32 的官方版本 nginx 0.7.53

進(jìn)行了試用以及壓力測試。

安裝使用方式很簡單，直接貼官方的方式：
Win32 Binaries

As of 0.7.52, Nginx is now available as an official Windows binary.

Installation:

cd c:\
unzip nginx-0.7.52.zip
ren nginx-0.7.52 nginx
cd nginx
start nginx

Control:
nginx -s [ stop | quit | reopen | reload ]

For problems look in c:\nginx\logs\error.log or in EventLog.

但要說明一下的，之前有第三方編譯的 Nginx For Windows 版本，是可以加載到 Windows 服務(wù)中運行的。但在這個官方版本下該方法行不通。所以建議暫時手動啟動，或者新建一個計劃任務(wù)開機啟動。

然后迫不及待進(jìn)行壓力測試。我們使用的工具是 Apache 的 ab , 測試的是純靜態(tài)頁面。就是 Nginx 一裝好后默認(rèn)的 ：
Welcome to nginx!

測試命令：./ab -c 100 -n 10000 http://192.168.3.50:8888/
操作系統(tǒng)：Windows server 2003 R2
硬件配置：Xeon 2.8G X2 1G RAM
測試結(jié)果：

由測試結(jié)果所得，Nginx for windows 100 個線程每秒只能處理 93 個請求。
如果再啟動多一個 ab 來壓，加起來就有200個線程，ab結(jié)果相當(dāng)。各端每秒處理93個請求。
但如果你再啟動第三ab 進(jìn)行 100 個線程壓力，正在進(jìn)行的2個ab 其中一個就會被服務(wù)端拒絕。

來回嘗試修改Nginx的worker_processes 參數(shù)無果，修改了 Win2003 的并發(fā)線程也無果….難道 Nginx 在Windows下就只能有這么點能耐？？回頭要再詳細(xì)找找原因。

另外還有一個問題，當(dāng)壓力測試完畢了，在 windows 中查看進(jìn)程會發(fā)現(xiàn) Nginx 還占著 2~30 的cpu。
在命令行下 Nginx -s stop 也無法停止。必須 結(jié)束進(jìn)程…..

初步嘗試就這幾點，希望是我個別的問題，有機會的朋友也不妨試試。
