Adjusting the Upload File Size Limit for the File Manager in Plesk

Introduction

The File Manager built into Plesk has a default size limit for uploadable files. This limit is set to 2 GB by default. To upload larger files via the File Manager, you’ll need to make some adjustments in Plesk. In this article, you’ll learn how to adjust the size limit for uploadable files.

Prerequisites

• Unmanaged server with Plesk Control Panel

Adjust PHP Settings

You can configure the maximum file size and the maximum request size using the PHP configuration variables upload_max_filesize and post_max_size. Open the file /usr/local/psa/admin/conf/php.ini with a text editor of your choice and adjust the variables as desired. Be sure to specify the values in bytes.

Example (adjusting to 20GB):

nano /usr/local/psa/admin/conf/php.ini

post_max_size = 21474836480
upload_max_filesize = 21474836480

Adjusting the Plesk Panel Web Server Configuration

The client_max_body_size configuration variable of the Plesk-specific web server determines the maximum allowed size of a client’s request body. Open the file /etc/sw-cp-server/config with a text editor of your choice and adjust the variable as desired.

Example:

nano /etc/sw-cp-server/config

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include 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"'
 "'$fastcgi_script_name' '$fastcgi_path_info' '$document_root'";

    sendfile on;
    reset_timedout_connection on;

 #keepalive_timeout  0;
    keepalive_timeout  65;
    #tcp_nodelay on;

 #gzip  on;
    #gzip_disable "MSIE [1-6]\.(?!.*SV1)";

 server_tokens off;

 fastcgi_max_temp_file_size 0;
    fastcgi_buffers 16 16k;
    fastcgi_buffer_size 32k;
    fastcgi_pass_header X-Accel-Buffering;

 client_max_body_size 2048m; <----------------------------------- Make adjustments here

 error_page 497 https://$hostname:$server_port$request_uri;

 include /etc/sw-cp-server/conf.d/*.conf;
}

Restart the Plesk Panel Web Server

To apply your changes, the Plesk-specific web server must be restarted. To do this, run the command systemctl restart psa. Then log out of the Plesk interface and log back in so that the changes take effect. Afterward, you will be able to successfully upload files larger than the predefined limit.
