Nginx Error 413 - php

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: 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;
}
}
}

Answer 1

Not knowing the version of your nginx build and what modules it was built with makes this tough, but try the following:
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.
Are you using nginx_upload_module? If so make sure you have the upload_max_file_size 300MB; line in your config as well.

My setup was:
php.ini
...
upload_max_filesize = 8M
...
nginx.conf
...
client_max_body_size 8m;
...
The nginx showed the error 413 when it was uploaded.
Then I had an idea: I will not let nginx show the error 413, client_max_body_size set to a value greater than upload_max_filesize, thus:
php.ini
...
upload_max_filesize = 8M
...
nginx.conf
...
client_max_body_size 80m;
...
What happened?
When you upload smaller than 80MB nginx will not display the error 413, but PHP will display the error if the file is up to 8MB.
This solved my problem, but if someone upload a file larger than 80MB error 413 happens, nginx rule.

I also add that you could define it in the *.php location handler
location ~ ^/([a-z,0-9]+)\.php$ {
Being the "lower" one in the cascading level, it would be an easy way to see if the problem comes from your nginx config or modules.
It sure doesn't come from PHP because the 413 error "body too large" is really a NGinx error.

Try the following steps to resolve the error.
Open the Nginx configuration file (nginx.conf) in a text editor.
$ sudo nano /etc/nginx/nginx.conf
Add the directive client_max_body_size under the http block:
http {
# Basic Settings
client max body size 16M;
...
}
Open nginx default file in a text editor
$ sudo nano /etc/nginx/sites-enabled/default
Add the directive client_max_body_size under location block.
location / {
...
client_max_body_size 100M;
}
Restart Nginx using the following command.
$ sudo systemctl restart nginx
Optional:
If you have a time-consuming process running on the backend server then you have to adjust the timeout attribute of the server to avoid 504 timeout error.
Open the Nginx default file in a text editor
$ sudo nano /etc/nginx/sites-enabled/default
Add the directives proxy_connect_timeout, proxy_send_timeout proxy_read_timeout under the location block:
location /api {
client_max_body_size 100M;
proxy_connect_timeout 6000;
proxy_send_timeout 6000;
proxy_read_timeout 6000;
proxy_pass http://localhost:5001;
}
Restart Nginx using the following command.
$ sudo systemctl restart nginx
