Apache website conversion from alias to virtualhost

I have to take over an internal Web server that has been configured by a colleague who is no longer there. Our developer team asks me to convert applications URLs from an Alias to a Virtualhosts (subdomain naming) system. For instance:

https://srv-intra.mydomain.fr/basecolldev

should become

https://basecolldev.mydomain.fr

Environment specifications:

  • Linux OpenSUSE Leap 15.3
  • Server version: Apache/2.4.51 (Linux/SUSE)
  • PHP 7.4.6 (cli) ( NTS )

Issue description: I can connect to https://basecolldev.mydomain.fr despite some 404 errors showing in access_log file (see at the end of the post). I have then a 404 error page when clicking the login button that redirects to https://basecolldev.mydomain.fr/login. The login page is found and displayed properly when I manually modify the URL to https://basecolldev.mydomain.fr/index.php/login. This means that /index.php is not required for home page connection but is for browsing the website. I need to permanently prevent the /index.php suffix to show up in URL.

I describe below what I have configured so far and what remains unfunctionnal.

I have first created a new vhost file /etc/apache2/vhost.d/basecolldev-ssl.conf :

<VirtualHost basecolldev.mydomain.fr:443>

    DocumentRoot "/var/www/BaseCollDev/public"
    ServerName basecolldev.mydomain.fr
    ErrorLog /var/log/apache2/basecolldev-error_log
    TransferLog /var/log/apache2/basecolldev-access_log
    LogLevel alert rewrite:trace8

    <Directory /var/www/BaseCollDev/public>
         #Order allow,deny
         #allow from all
         #AllowOverride All
         Require all granted
         Options -Indexes -Includes -ExecCGI -FollowSymlinks
    </Directory>

</VirtualHost>

I have then commented the lines related to the application Directory tag in file /etc/apache2/default-server.conf :

DocumentRoot "/var/www"

<Directory "/var/www">
    Options FollowSymLinks
    AllowOverride None
    <IfModule !mod_access_compat.c>
            Require all granted
    </IfModule>
    <IfModule mod_access_compat.c>
        Order allow,deny
        Allow from all
    </IfModule>
</Directory>

Alias /icons/ "/usr/share/apache2/icons/"
Alias /phpmyadmin "/srv/www/htdocs/phpMyAdmin"

<Directory "/usr/share/apache2/icons">

        Order allow,deny
        Allow from all
    </IfModule>
</Directory>

I see no logs in /var/log/apache2/basecolldev-error_log file.


I closed .htaccess files contents if necessary.

File /var/www/.htaccess :

# BEGIN WordPress

    RewriteEngine On
    RewriteBase /
    RewriteRule ^index.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
# END WordPress

File /var/www/BaseCollDev/public/.htaccess :

DirectoryIndex index.php

<IfModule mod_negotiation.c>
