Moving Laravel Core Files to private_html Directory

As a security precaution, my boss has requested I move my Laravel 7 app outside the public_html folder and into private_html.

So my directory structure looks like this:

public_html/public/

private_html/ <-- All the rest of the Laravel core files, app, config, routes, .env, etc.

Now, as expected since I moved the files, I’m getting an HTTP ERROR 500 when I visited the the website.

How do I tell Laravel where my public folder is so can get back to serving my web pages? Which configuration files do I need to edit?

Thanks for any help.

Edit 1: After trying Youssef’s suggestion, everything worked great except when I run

php artisan storage:link

I get:

Edit 2:

I was able to fix “php artisan storage:link” by opening config/filesystems.php and changing:

'links' => [
    public_path('storage') => storage_path('app/public'),
],

To:

'links' => [
    '/new/directory/public_html/public/storage' => storage_path('app/public'),
],

Then, when I type:

php artisan storage:link

A new symlink is created.

Answer

In public/index.php change path of this two files to current path of them.

first line path of autoload.php

__DIR__.'/../vendor/autoload.php';

to

require __DIR__.'/../../private_html/vendor/autoload.php';

second line path of app.php

$app = require_once __DIR__.'/../bootstrap/app.php';

to

$app = require_once __DIR__.'/../../private_html/bootstrap/app.php';

and put this in the AppProvidersAppServiceProvider register() method to set path of public directory.

**
 * Register any application services.
 *
 * @return void
 */
public function register()
{
    // ...

    $this->app->bind('path.public', function() {
        return base_path().'/../public_html/public';
    });
}

finally reassign path of storage directory if you need access to stored files directly, using command :

php artisan storage:link

you can also move all files from public_html/public to public_html and adjust paths I mentioned above
