如何配置Apache以使Symfony4路由在WordPress域的子目录中工作

Question

On my Apache server I have a WordPress installation working on www.domain.com and I want to add a Symfony4 installation on www.domain.com/symfony. Symfony routes are taken to the WordPress 404 page (but still are the correct URL ie www.domain.com/symfony/about). However, if there are NO routes defined in my Symfony app, then the base www.domain.com/symfony/ URL will correctly display the Symfony4 getting started page. What is wrong in my Apache conf files?

Web server is Apache 2.4, I have tried using Alias and AliasMatch directives in the /etc/apache2 conf files. Alias displays WordPress 404 for all Symfony routes and AliasMatch appends many /index.php's onto the URL and displays the same 404. I tried to copy what phpmyadmin does with its Alias /phpmyadmin /usr/share/phpmyadmin

# /etc/apache2/sites-available/wordpress.conf
<Directory /var/www/wordpress>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>
<VirtualHost *:80>
    ServerName domain.com
    ServerAlias www.domain.com
    ServerAdmin me@myemail.com
    DocumentRoot /var/www/wordpress
</VirtualHost>


# /var/www/wordpress/.htaccess
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>


# /etc/apache2/sites-available/symfony.conf
Alias /symfony /var/www/symfony/app/public
<Directory /var/www/symfony/app/public>
    Options FollowSymLinks
    AllowOverride All
    Require all granted
    Allow from All
    FallbackResource /index.php
</Directory>


# /var/www/symfony/app/config/routes.yaml
about_index:
  path: /about
  controller: App\Controller\AboutController::index

I expected www.domain.com/symfony/about to go to /var/www/symfony/app/public/index.php and route to App\\Controller\\AboutController::index , but it looks like WordPress is trying to find the page /symfony/about and 404's.

When I change my Alias /symfony /var/www/symfony/app/public to AliasMatch ^/symfony.* /var/www/symfony/app/public it changes the Symfony URL to www.domain.com/symfony/index.php/index.php/index.php/index.php/index.php/index.php but has the same result (WordPress 404 page). None of my changes have impacted the WordPress part at all - it still functions perfectly.

EDIT 1

Tried a new conf to test if it's my symfony config - it works as expected so I just think it must be something in my Apache confs. This config treats the symfony app as the main site and wordpress is totally disabled:

# /etc/apache2/sites-available/symfony_only.conf
<Directory /var/www/symfony/app/public>
    Options FollowSymLinks
    AllowOverride All
    Require all granted
    Allow from All

    FallbackResource /index.php
</Directory>

<Directory /var/www/symfony/app/public/bundles>
    FallbackResource disabled
</Directory>

<VirtualHost *:80>
    ServerName domain.com
    ServerAlias www.domain.com
    ServerAdmin me@myemail.com
    DocumentRoot /var/www/symfony/app/public
</VirtualHost>

Looks like I got a working conf now. Not sure if it's even resulting in any different configuration than the one I had. I also did a lot of php bin/console cache:clear as I was even getting 404 and 500 errors on the little debug bar at the bottom of the symfony welcome page (not displayed on the bar, but the bar actually wouldn't properly load). The below file is my entire conf which I combined into one file. It serves from my Symfony4 app if the url path begins with /symfony , and the routes all work.

# /etc/apache2/sites-available/wordpress_symfony.conf
Alias /symfony /var/www/symfony/app/public

<Directory /var/www/symfony/app/public>
    AllowOverride All
    Require all granted
    Allow from All
    FallbackResource /index.php
</Directory>

<Directory /var/www/symfony/app/public/bundles>
    FallbackResource disabled
</Directory>

<Directory /var/www/wordpress>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

<VirtualHost *:80>
    ServerName domain.com
    ServerAlias www.domain.com
    ServerAdmin me@myemail.com
    DocumentRoot /var/www/wordpress

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Also I added the symfony/apache-pack with composer which added this .htaccess in the symfony public directory. The docs said I can get improved performance by moving all these rules into my .conf file and disabling overrides:

# /var/www/symfony/app/public/.htaccess
DirectoryIndex index.php

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]
    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 307 ^/$ /index.php/
    </IfModule>
</IfModule>
