How can I change the default start page in .htaccess

By default start page is index. This means that this page will be shown first when you access your domain. Furthermore, index.php will always be shown before index.html, meaning that for example your PHP site is shown and not your Website Builder (HTML) site.

Step 1. Enable mod_rewrite on your Apache web server.

Step 2. Create .htaccess file in root directory.

Step 3.Update default page for your website home.html in .htaccess file

       DirectoryIndex home.html

Step 4. Restart Apache Server  
        sudo service apache2 restart
