Everything in Symfony2 uses or is a bundle [a collection of code that serves a single useful purpose]. In order to use the bundle it has to be registered in some way. This “Registration” takes place in the AppKernel.php. any bundle that you create, will be registered here.

So the files we will be editing is app/AppKernel.php, app/config/routing_dev.yml and we will be removing the src/Acme folder.

The App Kernel

here we have to remove the line $bundles[] = new Acme\DemoBundle\AcmeDemoBundle();

<?php
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
          ...
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Acme\DemoBundle\AcmeDemoBundle(); /**Remove this line **/
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            ....
        }
        return $bundles;
    }
}

 The routing_dev.yml

any route prefixed with _demo and _welcome can be removed

_welcome:
    pattern:  /
    defaults: { _controller: AcmeDemoBundle:Welcome:index }

_demo_secured:
    resource: "@AcmeDemoBundle/Controller/SecuredController.php"
    type:     annotation

_demo:
    resource: "@AcmeDemoBundle/Controller/DemoController.php"
    type:     annotation
    prefix:   /demo

.......

 Deleting the Acme Directory

Now the only thing left to do is delete the src/Acme folder, and that’s  it!

To get started with Symfony 2, you will require a Web server (such as Apache) with PHP 5.3.2 or higher. If you want to use source control to store your project, this tutorial uses git.

Lets start by download the zip file from the Symfony website. make sure you select Symfony Standard 2.0.15 without vendors.

1. unzip the Symfony_Standard_2.0.15.zip into your web directory

   

2. If you want to use Git to store your project create a new file .gitignore in your ~/Sites/sf2demo directory

   /web/bundles/
   /app/bootstrap*
   /app/cache/*
   /app/logs/*
   /vendor/
   /app/config/parameters.ini

3. Copy app/config/parameters.ini to app/config/parameters.ini.dist. By doing this a new developer can quickly clone the repository, and add their own database passwords and settings, for their local machine.
4. Init Git by running

   ~Sites/sf2demo]$ git init

5. Add files to your local git repository

   ~Sites/sf2demo]$ git add .

6. Make the First Commit

   ~Sites/sf2demo]$ git commit -m "First commit"

7. Now we can install the vendors

   ~Sites/sf2demo]$ php bin/vendors install

8. Lock your current vendors installation

   ~Sites/sf2demo]$ php bin/vendors lock

9. Clean up the vendor install

   ~Sites/sf2demo]$ find vendor -name .git -type d | xargs rm -rf

10. File permissions to allow cache and logs to be written

    ~Sites/sf2demo]$ chmod -R 777 app/cache/ app/logs/

What are the vendors for?

The vendors directory contains all of source code [including the Symfony source code] to allow your application to work. Since Symfony2 is highly decoupled, it allows you to include and exclude particular modules or “bundles” that you do not need. for example symfony2 vendors come standard with Doctrine ORM, if you do not need a ORM Mapper of want to install a new one, simply remove or add the vendor in the deps file in ~/Sites/sf2demo. the deps.lock file makes sure that when you run

~Sites/sf2demo]$ php bin/vendors install

again, it will install the project specific vendor version defined in deps.lock. So if you want to upgrade a specific vendor, edit your deps.lock and deps files to set the version of the module you want to install, then run

~Sites/sf2demo]$ bin/vendors install --reinstall

to re-install your project specific vendors.

Virtual Host setup

This will allow you to setup a local domain name when viewing your site in a web browser, each operation system has it own directory structure and file locations, for most Linux and Mac OS X the directories will be the same or similar.

The Host File

1. Edit the host file
   

   ~]$ sudo vim /etc/hosts

   
   Your host file should look some think like this
   

   127.0.0.1       localhost
   
   255.255.255.255 broadcasthost
   ::1             localhost
   fe80::1%lo0     localhost

2. Add the highlighted text to the file
   

   127.0.0.1       localhost
   127.0.0.1       sf2demo.local
   
   255.255.255.255 broadcasthost
   ::1             localhost
   fe80::1%lo0     localhost

   
   vim hints: press i to start inserting text, use arrow keys to navigate, press esc to stop editing text, press : x [then enter] to save

The Virtual Host file

1. Create a virtual host file
   

   ~]$ sudo vim /etc/apache2/sites/0000_any_80_sf2demo.local.conf

2. Insert the virtual host information [make sure you use your site directory]
   

   <VirtualHost *:80>
           ServerName sf2demo.local
           ServerAdmin your@email.com
           DocumentRoot "/Users/yourusername/Sites/sf2demo/web"
           DirectoryIndex app_dev.php
           CustomLog /var/log/apache2/access_log combinedvhost
           ErrorLog /var/log/apache2/error_log
   
           <IfModule mod_ssl.c>
                   SSLEngine Off
                   SSLCipherSuite "ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM"
                   SSLProtocol -ALL +SSLv3 +TLSv1
                   SSLProxyEngine On
                   SSLProxyProtocol -ALL +SSLv3 +TLSv1
           </IfModule>
   
           <Directory "/Users/yourusername/Sites/sf2demo/web">
                   Options All +MultiViews -ExecCGI -Indexes
                   AllowOverride All
                   <IfModule mod_dav.c>
                           DAV Off
                   </IfModule>
           </Directory>
   </VirtualHost>

3. Edit your http.conffile to include your virtual host
   

   ~]$ sudo vim /etc/apache2/httpd.conf

   
   Insert content in your httpd.conf if it does not exist [this is for Mac OS X Server]
   

   <IfDefine MACOSXSERVER>
       <IfDefine WEBSERVICE_ON>
           Include /etc/apache2/sites/*.conf
       </IfDefine>
       <IfDefine !WEBSERVICE_ON>
           Include /etc/apache2/sites/virtual_host_global.conf
           Include /etc/apache2/sites/*_.conf
           Include /etc/apache2/sites/*__shadow.conf
       </IfDefine>
   </IfDefine>

4. Restart Apache
   

   ~]$ sudo apachectl restart

The .htaccess file

1. Edit your .htaccess file in ~Sites/sf2demo/web
   

   Sites/sf2demo]$ vim web/.htaccess

2. modify app.php to reflect app_dev.php
   

   <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteRule ^(.*)$ app_dev.php [QSA,L]
   </IfModule>

   
    

Viewing the site

Open up your browser and type enter the Url specified in your host and virtual host files sf2demo.local you should see the Symfony2 configuration page. you can now proceed to configure your application.
