How Symfony routing works - php

Question

I am a beginner for Symfony and following the Symfony documentation and it has a create page tutorial
and after creating this this when I test this using the browser,
I can access it using the following URLs
localhost:8000/lucky/number and
localhost:8000/app_dev.php/lucky/number
but when I try to access it using the usual way like
localhost/appname/lucky/number
it gives 404 and I use Ubuntu with Apache2 localhost so I need to know the idea behind this Symfony3 routing and why I cannot access the page using usual localhost/cmstest/lucky/number
Thanks

Answer 1

Following the Symfony doc, this is how your vhost should looks like:
<VirtualHost *:80>
DocumentRoot /var/www/MySymfonyProject/web
<Directory /var/www/MySymfonyProject/web>
AllowOverride None
Order Allow,Deny
Allow from All
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
</Directory>
<Directory /var/www/MySymfonyProject/web/bundles>
<IfModule mod_rewrite.c>
RewriteEngine Off
</IfModule>
</Directory>
ErrorLog /var/log/apache2/MySymfonyProject_error.log
CustomLog /var/log/apache2/MySymfonyProject_access.log combined
</VirtualHost>
Now that you have a clean vhost, here are some details/instructions:
All terminal commands are done as admin (sudo).
In terminal, run this command a2enmod rewrite
In terminal, as you don't use any URL, make sure to disable the default vhost a2dissite 000-default.conf
In terminal, make sure to enable your site vhost a2ensite myVhost.conf
Make sure your project directory is right /var/www/MySymfonyProject
In terminal, restart apache service with service apache2 restart
Access your site through localhost or localhost/app_dev.php (you don't have to specify the bundle name)

Answer 2

Because you have to use the web/ directory (which is the public root of your application, only this directory should be accessible using the browser).
When using server:run, it'll use web/ as your server root automatically. When accessing via the directory structure, include it in the URL: http://localhost/appname/web/lucky/number

Hewwo PM-Riabel~
Can you paste here your virtual-host config?
Your first problem may be in it...
Do you have only one virtual-host active on your machine?
I would guess you try to view it from Linux (correct me if it's not the case)
You should set a fictive URL to your hosts file (myurl.com) and redirect it to 127.0.0.1 (localhost)
Then you can configure your virtual-host to work with this same URL. (Better do it when you want to work multiple projects)
Cordially,
