fast-cgi 启动了，但是 nginx 无法执行 php

我用的是ubuntu12.04,php是5.2.10然后用的spawn-fcgi。top里面能看到php5-cgi启动起来了，访问html没问题，我用nginx upstream转发到apache（8080端口）也能执行php程序，就是fastcgi有问题。网页提示502，日志 connect() failed (111: Connection refused)

connect() failed (111: Connection refused) while connecting to upstream, client: 123.151.148.160, server: new.cdfdc.gov.cn, request: "GET /archive.php?addno=8&aid=120&ccid12=3032&ccid5=184&ccid6=188&fang=zhu&sort=mj:1 HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "new.cdfdc.gov.cn", referrer: "http://new.cdfdc.gov.cn/"
服务器内存什么的消耗都很低，基本上不会是资源不足问题。另外fastcgi进程使用数也远远没有达到我的设定的进程数目
我的网站配置
server {
listen 80;
server_name fdcsck.com www.fdcsck.com;

# handling 404 error for root
error_page 404 /index.html;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/sck_error.log;
location / {
    root   /var/www/fdcsck;
    index  index.php index.html index.htm;
}
location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass 127.0.0.1:9000;
    #fastcgi_pass unix:/var/run/php-fastcgi/php-fastcgi.socket;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME  /var/www/fdcsck$fastcgi_script_name;
}

nginx 配置

user www-data;
worker_processes 2;
pid /var/run/nginx.pid;

events {
worker_connections 768;
# multi_accept on;
}

##
# Basic Settings
##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    client_max_body_size 100m;
    # server_tokens off;
    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

求各位大神指点。小弟感激不尽
