laravel install getting key generate error in ubunto OS

Question

I am install "Laravel Framework version 5.2.26" but i am getting error for key generate in my ubuntu os

user@CN43:/var/www/html/laravel_1$ php artisan key:generate

  [ErrorException]                                                             
  file_get_contents(/var/www/html/laravel_1/.env): failed to open stream: No   
  such file or directory

So i have check that directory .env file is not there but .env.example file only there so i created that file and update database name, database username, database password after that "php artisan key:generate" command is worked that key was generated above 32 characters and its get [base64:somethingsstrings with above 32 characters] i think some installation issues is there.

my laravel site is not opening. what i do mistake?

Answer 1

Run this command and make .env file from .env.example file:

cp .env.example .env
php artisan key:generate

Now it's generate the key. Don't create new .env file.

Answer 2

Rename .env.example to .env and fill all properties.

If you install Laravel via Composer, this file will automatically be renamed to .env. Otherwise, you should rename the file manually
