How to configure redirect from Web Server's Default Page to Plesk login page on Plesk for Linux server?

Login to the server using SSH.

Create the file /var/www/vhosts/default/htdocs/.htaccess:

# touch /var/www/vhosts/default/htdocs/.htaccess

Add the following content to it using text editor:

CONFIG_TEXT: RewriteEngine On
RewriteCond %{HTTP_HOST} ^203.0.113.2$
RewriteCond %{HTTP_HOST} ^203.0.113.3$
RewriteRule ^.*$ https://example.com:8443/ [R,L]
Redirect 301 / https://example.com:8443/

Note: 203.0.113.2, 203.0.113.3 and example.com should be replaced with public IP addresses and hostname of the server respectively.

Log into Plesk.

Go to Domains > example.org > Apache & nginx Settings.

Add the following additional directives:

• If the field Additional nginx directives is present, add the following content to it's beginning:

  CONFIG_TEXT: return 301 https://example.com:8443/;

• If the field Additional nginx directives is absent, add the following content to both fields Additional directives for HTTP and Additional directives for HTTPS:

  CONFIG_TEXT: Redirect "/" "https://example.com:8443/"

Note: example.com should be replaced with the hostname of the server.
