配置目的： 一个子目录下的代码使用框架，其他部分不采用。 配置如下（仅server段，其他参见nginx文档）：
server {
listen 80;
server_name localhost.dev;
index index.php index.html index.htm i.php;
set $root_path '/var/www/';
root $root_path;
client_max_body_size 2M;
location /backend {
# if (-f $request_filename) { break; }
rewrite ^/backend/(.*)$ /backend/public/index.php?_url=/$1;
}
location ~ \.php {
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index /index.php;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ~* ^/(css|img|js|flv|swf|download)/(.+)$ {
root $root_path;
}
location ~ /\.ht {
deny all;
}
}
