Deploy Symfony 4 project on OVH

I'm trying to deploy my site created with Symfony 4 on OVH. I have my two .htaccess files (1 at the root in the www folder where my code is and the other in my public folder) :

RewriteEngine on
RewriteBase /

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://example.com/$1 [R,L]

RewriteCond %{REQUEST_URI} !^/public/
RewriteRule ^(.*)$ /public/$1 [L] `

and in my public folder :

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

and yet I have a 404 error that appears when I try to access my site.

Does anyone have any idea where the problem may come from?

Solution

OVH is your hosting service, it does not give us any information about your server's config and installs. Do you use Nginx or Apache ? PHP FPM or PHP CGI ?

Since you are using .htaccess files I'm assuming you have Apache installed.

Symfony has a recipe for installing the proper rewrite rules to run on Apache. You can run it by executing the following command : composer require symfony/apache-pack

Depending on your PHP install (CGI or FPM) there are different configurations for running Symfony on Apache. For PHP-CGI:

<VirtualHost *:80>
    ServerName domain.tld
    ServerAlias www.domain.tld

    DocumentRoot /var/www/project/public
    <Directory /var/www/project/public>
        AllowOverride All
        Order Allow,Deny
        Allow from All
    </Directory>

    # uncomment the following lines if you install assets as symlinks
    # or run into problems when compiling LESS/Sass/CoffeeScript assets
    # <Directory /var/www/project>
    #     Options FollowSymlinks
    # </Directory>

    ErrorLog /var/log/apache2/project_error.log
    CustomLog /var/log/apache2/project_access.log combined
</VirtualHost>

All these informations can be found in the official documentation: Symfony Web Server Configuration
