Question

I'm new to Laravel.

I've set up a Fedora 23 server through Oracle VirtualBox, installed composer and created a Laravel 5.3 project as the html folder (for convenience, since it's accessible by just the virtual machine's IP address). I also disabled its firewall, since this is just for testing/learning.

I gave storage folder 755 permissions, and I get the welcome page showing on browser by just typing http://«IP».

I created a index.blade.php view, with the same code as welcome.blade.php but changing the word Laravel to "Something". Now comes the problem.

I've created a HomeController.php controller, so that I could get the php artisan route:cache without errors, since if I returned the view on routes/web.php file, it gave me an error:

[myuser@webserver]$ php artisan route:cache
Route cache cleared!

[LogicException]
Unable to prepare route [/] for serialization. Uses Closure.

So my files look like this:

routes/web.php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| This file is where you may define all of the routes that are handled
| by your application. Just tell Laravel the URIs it should respond
| to using a Closure or controller method. Build something great!
|
*/

/*
Route::get('/', function () {
    return view('welcome');
});

Route::get('home', function () {
    return view('index');
});
*/

Route::get('/', 'HomeController@getWelcomePage');
Route::get('home', 'HomeController@homepage');

app/Http/Controllers/HomeController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

class HomeController extends Controller
{
        public function homepage(){
                return view('index');
        }

        public function getWelcomePage(){
                return view('welcome');
        }

}

After all this, I can see the welcome page by typing http://«IP», but if I type http://«IP»/home I only get a blank page. Browser tells me that the page returned with a 500 Internal Server Error, however at storage/logs/laravel.log nothing shows up (the last log was the error due to the php artisan route:cache not being able to execute due to the view being returned in the web.php file)

[2017-01-19 13:00:49] local.ERROR: exception 'LogicException' with message 'Unable to prepare
route [/] for serialization. Uses Closure.'
in /var/www/html/vendor/laravel/framework/src/Illuminate/Routing/Route.php:995

The weirdest part for me is that if I comment ALL the entries in the route file, I get a route not found exception for http://«IP»/home, but if I just type http://«IP» I still get the welcome blade.

I believe that my problem is something really simple, but after hours of searching and trial/error, I still can't solve this.

Any help/suggestions are welcome.

EDIT: My problem is not the Closure error, I created controller methods for the routes. My problem is that the server only gives the welcome blade, all others give me an 500 Internal Server Error

Answer 1

Finally got it!

After reading comments on https://woohuiren.me/blog/installing-laravel-5-on-fedora/ , an user that apparently had the same issue as me said the following:

Seem issue this command solve the blank page (error code 500)

$ cd laravel_project

$ php artisan cache:clear

$ chmod -R 777 storage

$ composer dump-autoload

I set SElinux to permissive, should be ok right?

I got the page showing with no problem.

Answer 2

It turns out you can't use any route caching with Laravel 5, if you have any routes as closures (because it won't cache the function). A closure being like:

Route::get('/', function() {
    return view('welcome');
});

Either stop caching your routes, or remove all of these closures. More information in this GitHub issue .

Answer 3

Sounds like the error your log isn't the one that is causing the 500 error. If you delete that log and try to navigate to that route then you won't see any errors. The last time I ran into this was my storage directories weren't created and/or the permissions on them weren't correct. Make sure your storage directory is writable by the webserver (I usually set to 775) and all directories exist. Create them if they don't:

storage/

|   |-- public/
