1.Nginx
1.1.安裝
Nginx 的中文維基 http://wiki.codemongers.com/NginxChs 下載 Nginx 0.6.26（開發版）（請下載最新版本）
tar zxvf nginx-0.6.26.tar.gz
./configure，注意了類似checking for *** ... not found項，可能是依賴包沒有，則需要安裝依賴包
缺少PCRE，sudo apt-get install pcre安裝。或者去：http://www.pcre.org/
如果缺少OpenSSL，sudo apt-get install libssl-dev，或者去：http://www.openssl.org
如果缺少zlib，可以apt-get install zlib1g，或者http://www.zlib.net/
配置請參考：http://wiki.codemongers.com/NginxChsInstall 可以選擇安裝模塊
make & make install
默認安裝在/usr/local/nginx下
1.2.管理
執行選項
-c </path/to/config> 為 Nginx 指定一個配置文件，來代替缺省的。
-t 不運行，而僅僅測試配置文件。nginx 將檢查配置文件的語法的正確性，并嘗試打開配置文件中所引用到的文件。
-v 顯示 nginx 的版本。
-V 顯示 nginx 的版本，編譯器版本和配置參數。
檢查配置文件
$ sudo nginx -t
2008/03/12 19:15:11 info 12384#0: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
2008/03/12 19:15:11 info 12384#0: the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
啟動
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
查看nginx主進程號
$ ps -ef | grep "nginx: master process"

| grep -v "grep"

| awk -F ' ' '{print $2}

26010
重新加載配置文件
$sudo kill -HUP 26010
通過系統的信號控制 Nginx
可以使用信號系統來控制主進程。默認，nginx 將其主進程的 pid 寫入到 /usr/local/nginx/logs/nginx.pid 文件中。通過傳遞參數給 ./configure 或使用 pid 指令，來改變該文件的位置。
主進程可以處理以下的信號：

命令 說明 備注
TERM, INT 快速關閉
QUIT 從容關閉
HUP 重載配置 用新的配置開始新的工作進程 從容關閉舊的工作進程
USR1 重新打開日志文件
USR2 平滑升級可執行程序
WINCH 從容關閉工作進程
默認目錄
主目錄：/usr/local/nginx/
配置目錄：/usr/local/nginx/conf/
root目錄：/usr/local/nginx/html/
可執行文件路徑：/usr/local/nginx/sbin/
2.FastCGI
2.1.安裝lighttpd的spawn-fastcgi
下載http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz

./configure
make
cp ./src/spawn-fcgi /usr/local/nginx/sbin/
2.2.安裝fastcgi庫
下載http://www.fastcgi.com/dist/fcgi.tar.gz

./configure
make
make install
2.3.Hello world
#include <iostream>
#include <fcgi_stdio.h>

using namespace std;

int main()
{

/* Initialization Code */
int count = 0;

/* Start of response loop */
while (FCGI_Accept() >= 0)
{
//* body of response loop /*/
printf("Content-type: text/html/r/n"
"/r/n"
""
"FastCGI Hello/! (C, fcgi_stdio library)"
"Request number %d running on host %s "
"Process ID: %d/n",
/++count,
getenv("SERVER_NAME"), getpid());
}

?

/* End of response loop */
return 0;

}
編譯后為FastCGISameple

2.4.啟動Spawn-cgi
/usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 25 -u www -f /usr/local/nginx/fcgi/FactCGISample
2.5.修改Nginx配置文件
vi /usr/local/nginx/conf/nginx.conf

location ~ /.cgi$

{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.cgi;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
別忘了，重新加載配置文件

$sudo kill -HUP 26010
打開瀏覽器，輸入http://localhost/1.cgi ，就顯示

FastCGI Hello! (C, fcgi_stdio library)Request number 1 running on host localhost Process

?

3.webbench壓力測試工具
下載：http://home.tiscali.cz:8080/~cz210552/distfiles/webbench-1.5.tar.gz

安裝：

tar zxvf webbench-1.5.tar.gz
cd webbench-1.5

make && make install
使用：

webbench -c 500 -t 30 http://127.0.0.1/test.jpg

?

500是并發連接數，30是時間單位是秒

?

用ab測試的結果，在我的虛擬機上，看起來性能很不錯

(Apache Bench是Apache自帶的工具包)

?
