Increase Nginx Upload Limit On Server With Plesk Panel

From the Plesk Panel you can set the PHP upload_max_filesize at Website & Domains -> PHP Setting. But if you’re using Nginx then you may also need to configure Nginx to allow larger uploads. We saw errors like this in the /var/log/nginx/error_log:

Fixing “504 Gateway Timeout” Errors On Plesk With Nginx

If your Plesk server is configured to run Nginx in from of Apache then you may encounter “504 Gateway Timeout” errors when executing long running PHP pages.  Nginx is acting as a reverse proxy for Apache. The “proxy_read_timeout” configuration setting in Nginx controls how long Nginx will wait for Apache to return a response.

ServerAlias On Nginx

On Apache web servers, each virtual host has a “ServerName” directive and zero or more “ServerAlias” directives. When converting to Nginx there is only one directive – “server_name” which takes the place of both of the Apache directives. The “server_name” directive takes a set of space delimited arguments listing domains that should match the virtual host. So for example if you have this Apache config:

Then for Nginx use:
