Hey guys. I'm asking this question here as a last resort, since I've been trying to solve the issue for almost two days now.

I'm trying to enable clean URL's on my Drupal web application. I have visited several public questions such as this one, but to no avail. My sincerest apologies if this is thus a repost.

Some (relevant) context:

• The project involves automatically setting up a VM using a Vagrant script.
• The VM has no GUI.
• Vagrant uses VirtualBox.
• Vagrant uses bento/centos-7.9 as a base box.
• I use WSL on my physical device whenever I need a terminal for PS or Linux commands.

I'm setting up a LAMP stack on the VM using the following:

• CentOS 7.9, as mentioned up above.
• Apache 2.4.6, as in:

yum -y install httpd

• MariaDB 10.5.9, as in:

wget https://downloads.mariadb.com/MariaDB/mariadb_repo_setup

chmod +x mariadb_repo_setup

./mariadb_repo_setup

yum -y install mariadb-server

• PHP 7.4.16, as in:

yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

yum-config-manager --enable remi-php74

yum -y install php php-mysql

• I'm storing the extracted contents of Drupal (index.php, update.php, core, sites ...) under /var/www/drupal/. I have given Apache recursive ownership of that folder as to not create a hassle having to set up permissions. It's not a production project anyway.

• In the /etc/httpd/conf/httpd.conf file, I have only touched the DocumentRoot, which I set to DocumentRoot "/var/www/drupal". I do not want to use .htaccess.

• When I run httpd -M | grep rewrite, I receive the output rewrite_module (shared). When I run phpinfo(); on a test page, mod_rewrite is present among the loaded modules.

Running the application, everything goes fine, and the following output is produced:

Drupal warnings top part

Drupal warnings bottom part

I'm aware of the other two warnings, but those are a worry for another day. When I continue despite the warnings, Apache loads index.php just fine:

However, the moment I click any button, this happens:

Screenshot of yet another problem

I suspect this is a consequence of the clean URL's not being enabled. However, as far as I know, all necessary modules have been installed.

What I have tried so far:

• In /etc/httpd/conf/httpd.conf, trying everything that's suggested here.
• In /etc/httpd/conf/httpd.conf, setting every AllowOverride option to All.
• Checking for compability issues.
• Moving the document root around.
• Much more...

Help would be greatly appreciated. Many thanks in advance. If you require any more information, I will respond as soon as possible.

Hey guys. The issue has been solved.

Somehow, it suddenly works. I am now able to navigate the website without a Not Found error popping up.

I retried a method that didn't work before, but now it does. There was no change in any other variables. I edited /etc/httpd/conf/httpd.conf. Besides already having changed DocumentRoot to /var/www/drupal, I also added another piece of configuration right under that:

<Directory "/var/www/drupal">
  RewriteEngine on
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_URI} !=/favicon.ico
  RewriteRule ^ index.php [L]
</Directory>

I obtained this information from here.

The CLEAN URLS warning is still present though:

But there seems to be no problem when continuing despite the warnings. In fact, in the application itself, navigating to the errors/warnings section, the CLEAN URLS warning isn't even there!
