Having trouble with Ubuntu LAMP stack

Question

I have installed Ubuntu 16.04 LTS, Apache2, Mysql 14, Php7. I have installed Drupal with a few difficulties. Specifically, I had to install php extensions and tweak the configs to enable those extensions, and finally the installation was successful. However, whenever I try to click on any link, the 404 Not found error page pops up. So technically I can't go anywhere beyond the CMS homepage. I installed another CMS, the same problem, can see the homepage, nothing beyond. Did anyone ever had this kind of issue? I tried the following three: changed the CMS folder ownership to www-data:www-data (my CMS folder is drupaltest)

sudo chown -R /var/www/html/drupaltest

in /etc/apache2/apache.conf file, added

<Directory /var/www/html/drupaltest/> 
  AllowOverride All
</Directory>

And also:

sudo a2enmod rewrite

Answer 1

I feel like you're missing .htaccess file. Usually its a hidden file, so make sure to show all files (including hidden files) and copy it and paste it into your local drupal folder.

Also,make sure you local server has mod_rewrite enabled to support clean URLs, if its not enabled then check this answer: How to enable mod_rewrite in Apache?.

Another suggestion is to turn off Clean URL from settings.php by adding the following code:

$conf['clean_url'] = 0;

if all these above step not working then please explain little more about your problem .
