Nginx：502 错误网关

我尝试安装 nginx。我以前用 lighttpd 但现在必须安装 nginx。你能帮我配置nginx吗？

我使用 debian 6。我的nginx.conf：

user www-data;
worker_processes 4;
pid /var/run/nginx.pid;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;
    gzip_disable "msie6";

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

我的网站启用/默认看起来像

server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6

    root /var/www; #!
    index index.php index.html index.htm; #1
    access_log      /var/log/nginx/access.log info;
    error_log       /var/log/nginx/error.log info;

    # Make site accessible from http://localhost/
    server_name localhost;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to index.html
            autoindex on;
            # Uncomment to enable naxsi on this location
            # include /etc/nginx/naxsi.rules
    }

    location /doc/ {
            alias /usr/share/doc/;
            autoindex on;
            allow 127.0.0.1;
            deny all;
    }

    location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one

    location ~ /\.ht {
            deny all;
    }
}

我添加到php.ini

cgi.fix_pathinfo = 0;     

    

php5-cgi 运行为

spawn-fcgi 127.0.0.1 -p 9000 -u www-data -f /usr/bin/php5-cgi

但是我收到502 错误（错误的网关）
我/var/log/说

2012/05/16 15:35:25 [error] 13427#0: *12 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /ndex.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost"

我没有运行sqpwn-fcgi=>php-cgi没有在监听端口9000。
