Laravel 5.5 - 1071 specified key was too long max key length is 767 bytes

Someday ago, i wan working on my new laravel 5.5 application in my new system, with new configuration. I was simply installed laravel 5.5 app and then i created mysql database and then i run migration, but i got following error on my terminal.

"[Illuminate\Database\QueryException]

SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table `users` add unique ` users_email_unique`(`email`))"

"[PDOException]

SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes"

After this i checked my migration but it was perfect syntax followed, i was thinking what will be issued. after debug i found issue was in unique() of migration. So i require to fix then, after i google search and found the perfect solution set string length on AppServiceProvider.

So let's add this way :

app/Providers/AppServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Schema::defaultStringLength(191);
    }
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

After i set Schema default string length, i solved my issue you can try this too.

I hope you found best solution....
