[nginx] nginx - client_max_body_size has no effect

You need to apply following changes:

1. Update php.ini (Find right ini file from phpinfo();) and increase post_max_size and upload_max_filesize to size you want:

   sed -i "s/post_max_size =.*/post_max_size = 200M/g" /etc/php5/fpm/php.ini
   sed -i "s/upload_max_filesize =.*/upload_max_filesize = 200M/g" /etc/php5/fpm/php.ini```
   

2. Update NginX settings for your website and add client_max_body_size value in your location, http, or server context.

   location / {
       client_max_body_size 200m;
       ...
   }
   

3. Restart NginX and PHP-FPM:

   service nginx restart
   service php5-fpm restart
   

NOTE: Sometime (In my case almost every time) you need to kill php-fpm process if it didn't refresh by service command properly. To do that you can get list of processes (ps -elf | grep php-fpm) and kill one by one (kill -9 12345) or use following command to do it for you:

ps -elf | grep php-fpm | grep -v grep | awk '{ print $4 }' | xargs kill -9
