one of our client trying to upload big file size which fails with the following error in
/var/www/vhosts/system/example.com/logs/proxy_error_log file:
Nginx support is enabled on the server:
/usr/local/psa/admin/bin/nginxmng -s Enabled
We try to adjust client_max_body_size in /etc/nginx/nginx.conf but it has no effect. Actually, Value for client_max_body_size directive is overwritten on domain level and is insufficient.
To resolve this error:
Add the following directives to /usr/local/psa/admin/conf/panel.ini file to customize Plesk defaults:
[webserver] nginxClientMaxBodySize = 2000m
If there is no /usr/local/psa/admin/conf/panel.ini file, You can create it from the sample file:
cp /usr/local/psa/admin/conf/panel.ini.sample /usr/local/psa/admin/conf/panel.ini
Now rebuild web server configuration files:
plesk sbin httpdmng --reconfigure-all
Please note: Execution of the above command could cause a significant downtime to the hosted websites if there are a big number of them. Perform such action during the maintenance timeframe
Adjust settings of PHP handler assigned to the domain. Go to Plesk > Tools & Settings > PHP Settings > X.X.XX FPM application in php.ini tab and adjust the following parameters:
post_max_size 2000m upload_max_filesize 2000m max_file_uploads 100
That’s all.
