Blade Engine, routes url, Css not recognized by Laravel 5.4 in CentOS

I am moving project from windows to CentOS (linux OS). I have put all the files of public folder in root/public_html and kept all other files in root/app_name.

I changed these 2 lines from index.php file:

From
====

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

To
==

require __DIR__.'/../app_name/bootstrap/autoload.php';
$app = require_once __DIR__.'/../app_name/bootstrap/app.php';

I see project home page loading in the browser but everything else is broken.

I cant see css loading or cant visit /login or /register page. on clicking login

It goes to : app_name/

on inspecting Console all the links in home page contains blade engine braces and therefore nothing seems to loads properly. How do I fix this?

I am using CentOS 6.

Project structure

app_folder
 -contains all other files and folders of the project
public_html
