After installing Magento prompt: HTTP ERROR 500, how to solve?

I installed Magento2 on UBUNTU14, Web Access http://localhost/can show the Apache hint it work! , but http://localhost/magento2/tip http ERROR 500
I installed it by using the following command:

Apt-get updateapt-get install git wgetwget-o/usr/local/bin/composer http://getcomposer.org/composer.pharchmod +x/usr /local/bin/composercd/var/wwwgit Clone Https://github.com/magento/magento2.gitcd/var/www/magento2composer Install

After the error, I checked the PHP error log, prompting the following:

[Thu Sep 08 11:03:34.275419 2016] [: ERROR] [PID 2214] [Client 127.0.0.1:41732] PHP Fatal error:uncaught exception ' magento\framework\exception\filesystemexception ' with message ' the file '/var/www/ Html/magento2/var/.regenerate "cannot be deleted Warning!unlink (/var/www/html/magento2/var/.regenerate): Permission Denied ' In/var/www/html/magento2/vendor/magento/framework/filesystem/driver/file.php:382nstack trace:n#0/var/www /html/magento2/vendor/magento/framework/filesystem/directory/write.php (173): magento\framework\filesystem\ Driver\file->deletefile ('/var/www/html/m ...
