Nginx + Php Fpm Upload Large Files Setup

Configuring Nginx and PHP 7 stack in Linux to increase or decrease file upload size limit

PHP web applications can use Nginx as the reverse proxy server and PHP FPM as the upstream server. Whenever yous come across HTTP file upload issues, limitation in file upload size is one common cause.

This post shows how to adapt the file upload size limit for your application running on a Nginx-PHP stack in Linux.

Ii sets of file upload size limit configuration to apply for Nginx-PHP LEMP stacks

The following digram is an analogy of how the browser communicates with the application server in a typical LEMP stack.

Every bit shown higher up, there are two machines that process HTTP requests received from HTTP clients. Therefore, we demand to utilise 2 sets of file upload size limit configuration - i for Nginx and the other for the PHP-FPM server.

Configuring file upload size limit for Nginx

Firstly, let'due south look at how we tin can configure file upload size limit for Nginx.

Locating the Nginx configuration file

A typical installation of Nginx associates the nginx binary with the PATH variable. Therefore, you can locate the Nginx configuration file by running the following control in your concluding programme:

sudo nginx -t        

When I run this on my Raspberry Pi three running Codiad Web IDE, I got the following output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf examination is successful        

As can be seen, nginx reported that it is taking configurations from /etc/nginx/nginx.conf . Given that, we know where to wait at for adjusting the file upload size limit for Nginx.

Configuring the file upload size limit for Nginx via client_max_body_size directive

One time you had figured out the location of the configuration file that you wish to edit, y'all tin can then proceed to add in the client_max_body_size directive with a value that you desire.

This directive defines the maximum allowed size of customer request body. In improver, the default value is 1 Megabyte. When nosotros set a value of 0 , we disable the checking of the client asking body size.

Since a file is included every bit the client request body, we will adjust the file upload size via the client_max_body_size directive.

Universal file upload size limit for HTTP requests fabricated to all upstream servers

In example you desire to allow a file smaller than 8 Megabytes to go through your Nginx server for all upstream servers, you will employ the client_max_body_size directive within the http block:

http {     # ...     client_max_body_size 8m;     # ... }        

Site specific file upload size limit

In instance yous want to apply some other file upload size limit for HTTP request made to a specific upstream server, y'all need to look for the server cake for that site. For example, the following configuration allows any file smaller than i Gigabytes to pass Nginx for my Raspberry Pi 3 file sharing website:

server {          # ...          listen 443;     server_name  ps.yourdomain.com;     client_max_body_size 1024m;     # ...  }        

Uri specific file upload size limit

You can too apply the file upload size limit to a specific Uri. For example, the post-obit configuration will apply a file upload size limit of ii Gigabytes for HTTP requests sent to http://www.adomain.com/upload:

server {          # ...          listen eighty;     server_name  www.adomain.com;          location /upload {         # ...         client_max_body_size 2048m;         # ...     }      # ...  }        

Configuring file upload size limit for PHP FPM 7

Lastly, let's look at how to configure file upload size limit for PHP FPM seven.

Locating the php.ini configuration file

Earlier yous proceed to configure the file upload size limit for PHP FPM 7, you need to find the php.ini configuration file. In full general, you can run the following command to look for php.ini :

sudo discover / -name php.ini        

Later on the command completes, you may find output similar to the following in your terminal screen:

/etc/php/vii.0/fpm/php.ini /etc/php/seven.0/cli/php.ini        

In this example, we will edit /etc/php/seven.0/fpm/php.ini to configure the file upload size limit for PHP FPM 7.

Configuring file upload size limit for PHP FPM 7 via upload_max_filesize and post_max_size

In order to change file upload size limit for PHP, we demand to modify two settings - upload_max_filesize and post_max_size .

The default value for upload_max_filesize is 2 Megabytes.

The default value for post_max_size is 8 Megabytes.

Note that the post_max_size has to exist larger than upload_max_filesize for large files.

In addition to those ii variables, you may want to set max_input_time to a higher value for large files. In this case, your clients volition be given more fourth dimension to upload files to your PHP FPM 7 server.

Universal file upload size limit for HTTP requests made to all PHP applications served by PHP FPM vii

To utilise a common file upload size limit for all PHP applications served by PHP FPM 7, you will edit the values for upload_max_filesize and post_max_size from /etc/php/7.0/fpm/php.ini .

For example, if we desire to change the file upload size limit to 200 Megabytes, we will first open up up /etc/php/7.0/fpm/php.ini. After the editor loads the file, nosotros will then change the lines with upload_max_filesize and post_max_size variables to the following:

upload_max_filesize = 200M post_max_size = 202M        

Awarding specific file upload size limit

To adjust the file upload size limit for unlike PHP applications served past PHP FPM vii, nosotros can do then via the ini_set function.

For example, if we want to change the file upload size limit to 300 Megabytes, we will include the following PHP codes in a running script:

@ini_set( 'upload_max_size' , '300M' ); @ini_set( 'post_max_size', '302M');        

Restarting Nginx and PHP FPM 7 for the new file upload size limit to take issue

Once you lot had included the new file upload size limit for your Nginx server and PHP FPM server, restart them:

sudo systemctl restart php7.0-fpm.service sudo systemctl restart nginx.service        

After your Nginx server and PHP FPM server had restarted, the new file upload size limit will accept effect.
