Chevereto Installation Error

I wanted to build a chevereto under the Debian8,apache2, but the installation failed.
First I put the Chevereto folder inside the/var/www/, and then wrote a conf to create the virtual directory, the code is as follows

Alias /chevereto/ "/var/www/chevereto/"
  
    AllowOverride All

Then open https://my domain name/chevereto follow the prompts to create the setting.php file, give the Imgages,content folder permissions
Open again to start redirecting to https://my domain name/chevereto/install, this page shows 404 Not Found
Do not know which step was wrong? What should I do to properly install it?
