当我尝试上传一个文件到我的网站时，我得到了Nginx“413 Request Entity Too Large”错误，但是在我的nginx.conf文件中我已经明确地声明了最大大小为250 MB，并且在php.ini中也修改了最大文件大小（是的，我重新启动了进程）.错误日志显示：
2010年12月6日04：15：06 [错误] 20124#0：*11975客户端拟发送过大正文：1144149字节，客户端：60.228.229.238，服务器：www.x.com，请求：“POST /上传HTTP/1.1”，主机：“x.com”，引用地址：“http://x.com/“
据我所知，1144149字节并不是250 MB......我是不是漏掉了什么？
下面是基本的Nginx配置：

user  nginx;
worker_processes  8;
worker_rlimit_nofile 100000;

error_log   /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
    use epoll;
}

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

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    client_max_body_size 300M;
    tcp_nopush      on;
    tcp_nodelay     on;
    server_tokens   off;
    gzip            on;
    gzip_static     on;
    gzip_comp_level 5;
    gzip_min_length 1024;
    keepalive_timeout  300;
    limit_zone   myzone  $binary_remote_addr  10m;

    # Load config files from the /etc/nginx/conf.d directory
    include /etc/nginx/sites/*;
}

以及站点的vhost：

server {
    listen      80;
    server_name www.x.com x.com;

    access_log  /var/log/nginx/x.com-access.log;

    location / {
        index   index.html index.htm index.php;
        root    /var/www/x.com;

        if (!-e $request_filename) {
            rewrite ^/([a-z,0-9]+)$ /$1.php last;
            rewrite ^/file/(.*)$ /file.php?file=$1;
        }

        location ~ /engine/.*\.php$ {
            return 404;
        }

        location ~ ^/([a-z,0-9]+)\.php$ {
            fastcgi_pass    127.0.0.1:9000;
            fastcgi_index   index.php;
            fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include     fastcgi_params;
        }
    }
}
