Open your .htaccess file under public folder of your project and add some random text at the top and save your file.

Now try to access your project.

Case 1:

If you are getting 500 Internal server error after adding a random text in .htaccess file.

It means it is working.

Case 2:

If you are still able to access public path of project which means  .htaccess it is not working yet.

so you need to enable it.

Open your apache2.conf file and Allow overwrite All.

<Directory /home/users/www>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted

here.

Now also you need to run two below commands for enabling mod rewrite rule.

a2enmod rewrite
  service apache2 restart
