Answer 1

you can use .htaccess

vegetable.abc.com/vegetable/index.php   

to

vegetable.abc.com/index.php

Rule in .httaccess file

RewriteEngine On

RewriteCond %{HTTP_HOST} ^vegetable\.abc\.com\/vegetable\/index\.php [NC]
RewriteRule ^$ https://vegetable.abc.com/index.php [R=302,L]

virtual host

<VirtualHost *:80>
    ServerAlias *.example.com
    VirtualDocumentRoot /var/www/%1/
</VirtualHost>
