Deployer: Deployer doesn’t create the file 'laravel.log'

[blsn]

On my VirtualBox (‘laravel/homestead’ Vagrant box), I have a Laravel 5 test application containing the following file: storage/logs/laravel.log

• After changing the above folder permission, I could push the file to GitHub.
• I point to /var/www/html/current/public in sites-enabled on my VPS.
• I 'successfully deployed' the app to the remote server (VPS).

deploy.php:

require 'recipe/laravel.php';
server('prod', 'myipaddress', 2210)
    ->user('root')
    ->password('mypassword')
    ->stage('production')
    ->env('deploy_path', '/var/www/html');
set('repository', 'https://github.com/my/repo');

The problem is that the file laravel.log is not being created on the remote server (missing).
(Because of that Apache default welcome page shows _Server error 500_).

Apache error log file (/var/log/apache2/error.log):

Why Deployer doesn’t create this file on my VPS? How to fix it?

The problem is that the file laravel.log is not being created on the remote server (missing).
(Because of that Apache default welcome page shows Server error 500).

500 error does not means the file is missing. You should confirm the file is here or not directly.
For example, ls -l /var/www/html/releases/20151124170720/storage/logs/laravel.log.

You should check the file permission. Becaseu the error messages is:

The stream or file "/var/www/html/releases/20151124170720/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied

[SOLVED]

• sudo chown -R root:www-data storage (ownership to members of..)
• sudo chmod -R g+rwX storage (permissions recursively)
• sudo chmod g+s storage (affect future sub-directories)
• .env was misisng on the remote server (.gitignore)
