413 Request Entity Too Large - File Upload Issue

Question

Source: http://www.cyberciti.biz/faq/linux-unix-bsd-nginx-413-request-entity-too-large/

Edit the conf file of nginx:

nano /etc/nginx/nginx.conf

Add a line in the http section:

http {
    client_max_body_size 100M;
}

Doen't use MB it will not work, only the M!

Also do not forget to restart nginx

systemctl restart nginx

-in php.ini (inside /etc/php.ini)

 max_input_time = 24000
 max_execution_time = 24000
 upload_max_filesize = 12000M
 post_max_size = 24000M
 memory_limit = 12000M

-in nginx.conf(inside /opt/nginx/conf)

client_max_body_size 24000M

Its working for my case

First edit the Nginx configuration file (nginx.conf)

Location: sudo nano /etc/nginx/nginx.conf

Add following codes:

http {
        client_max_body_size 100M;
}

Then Add the following lines in PHP configuration file(php.ini)

Location: sudo gedit /etc/php5/fpm/php.ini

Add following codes:

memory_limit = 128M 
post_max_size = 20M  
upload_max_filesize = 10M

sudo nano /etc/nginx/nginx.conf

Then add a line in the http section

http {
    client_max_body_size 100M;
}

don't use MB only M.

systemctl restart nginx

then for php location

sudo gedit /etc/php5/fpm/php.ini

for nowdays maximum use php 7.0 or higher

sudo nano /etc/php/7.2/fpm/php.ini     //7.3,7.2 or 7.1 which php you use

check those increasing by your desire .

memory_limit = 128M 
post_max_size = 20M  
upload_max_filesize = 10M

restart php-fpm

service php-fpm restart 

I add the changes directly to my virtualhost instead the global config of nginx, like this:

   server {
     client_max_body_size 100M;
     ...
   }

And then I change the params in php.ini, like the comments above:

   max_input_time = 24000
   max_execution_time = 24000
   upload_max_filesize = 12000M
   post_max_size = 24000M
   memory_limit = 12000M

and what you can not forget is to restart nginx and php-fpm, in centos 7 is like this:

  systemctl restart nginx
  systemctl restart php-fpm

Please enter domain nginx file :

nano /etc/nginx/sites-available/domain.set

Add to file this code

client_max_body_size 24000M;

If you get error use this command

nginx -t
