Question

When I try to upload a file to my site, I’m getting the Nginx “413 Request Entity Too Large” error, however in my nginx.conf file I’ve already explicitly stated the max size to be about 250MB at the moment, and changed the max file size in php.ini as well (and yes, I restarted the processes). The error log gives me this:

2010/12/06 04:15:06 [error] 20124#0:
*11975 client intended to send too large body: 1144149 bytes, client:
60.228.229.238, server: http://www.x.com, request: “POST
/upload HTTP/1.1”, host:
“x.com”, referrer:
“http://x.com/”

As far as I know, 1144149 bytes isn’t 250MB…
Is there something I’m missing here?

Here’s the base Nginx config:

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/*;
}

And the vhost for the site:

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;
        }
    }
}

Not knowing the version of your nginx build and what modules it was built with makes this tough, but try the following:

1. Copy your client_max_body_size 300M; line into the location / { } part of your vhost config. I’m not sure if it’s overriding the default (which is 1 MB) properly.

2. Are you using nginx_upload_module? If so make sure you have the upload_max_file_size 300MB; line in your config as well.
