1，安装nginx，执行以下命令，很快完成，不过目前apg-get方式安装默认是0.5.33的版本
sudo apt-get install nginx
配置文件默认安装位置：
[quote]conf: /etc/nginx/nginx.conf
bin：/usr/sbin/nginx
vhost: /etc/nginx/sites-enable/default
cgi-params: /etc/nginx/fastcgi-params[/quote]
建一个虚拟Server
server {
listen 80;
server_name www.23day.com;
access_log /var/log/nginx/home.ucenter.access.log;
location / {
root /var/www/23day.com;
index index.php;
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/23day.com$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
}
2，安装php-cgi模块
执行sudo apt-get install php5-cgi
配置文件默认安装位置：
php-cgi: /usr/bin/php-cgi
php5-cgi: /usr/bin/php5-cgi
cgi config: /usr/bin/cgi/php.ini [/quote]
修改php.ini文件的cgi.fix_pathinfo数据为1，默认为0 cgi.fix_pathinfo=1; 这样php-cgi方能正常使用SCRIPT_FILENAME这个变量.
3，安装spawn-fcgi spawn-fcgi是lighttpd的一个用来控制php-cgi的工具.
如果系统没有安装GCC编译环境，刚需要在安装lighttpd之前要安装build-essential工具包，执行以下命令
sudo apt-get install build-essential
wget http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz
tar -xvf lighttpd-1.4.19.tar.gz
cd lighttpd-1.4.19/
sudo apt-get install libpcre3-dev
./configure –without-zlib –without-bzip2
make
sudo cp src/spawn-fcgi /usr/local/bin/spawn-fcgi
这样cgi控制器就安装完成.
4.启动测试系统.启动fast_cgi:
spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php-cgi
注意:ip,端口与nginx服务器中的cgi-pass要对应. -C表示打开几个cgi进程
启动nginx
sudo /etc/init.d/nginx start
好了，如果没有出错信息，则说明配置成功了，现在写个phpinfo测试下吧！
最后，附上我的/etc/nginx/sites-enable/default的配置文件，此配置文件启用了rewrite功能
server {
listen 80;
server_name localhost;
access_log /var/log/nginx/localhost.access.log;
location / {
root /var/www/nginx-default;
index index.php;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}
}

}

fastcgi_param SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
