Get started with Symfony

NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:

 $ test ! -f "/opt/bitnami/common/bin/openssl" && echo "Approach A: Using system packages." || echo "Approach B: Self-contained installation."

The output of the command indicates which approach (A or B) is used by the installation, and will allow you to identify the paths, configuration and commands to use in this guide. Refer to the FAQ for more information on these changes.

Approach A: Bitnami installations using system packages

The Symfony framework is not installed by default in Bitnami installations using system packages. However, it can be easily enabled via the Symfony CLI tool. In this guide, you will learn how to install and configure a Symfony project.

Installation and Testing

NOTE: This section assumes that the application project directory will be located at /opt/bitnami/projects/APPNAME. Remember to replace the APPNAME placeholder with the application name, such as myapp.

  • First, install the Symfony CLI tool and make it available in your PATH. Run the following commands:

    $ wget https://get.symfony.com/cli/installer -O - | bash
    $ sudo mv /home/bitnami/.symfony/bin/symfony /usr/local/bin/symfony
    
  • Create a project directory where to store your application. Run the following commands:

    $ sudo mkdir -p /opt/bitnami/projects/APPNAME
    $ sudo chown $USER /opt/bitnami/projects/APPNAME
    
  • Create the Symfony project:

    $ symfony new --full --no-git /opt/bitnami/projects/APPNAME
    
  • Create the Apache configuration for your application. Follow these steps:

    • Create the /opt/bitnami/apache2/conf/vhosts/APPNAME-vhost.conf file containing the application’s HTTP virtual host configuration with the configuration block shown below:

      <VirtualHost 127.0.0.1:80 _default_:80>
        ServerAlias *
        DocumentRoot /opt/bitnami/projects/APPNAME/public
        <Directory "/opt/bitnami/projects/APPNAME/public">
          Options -Indexes +FollowSymLinks -MultiViews
          AllowOverride All
          Require all granted
        </Directory>
      </VirtualHost>
      
    • Create the /opt/bitnami/apache2/conf/vhosts/APPNAME-https-vhost.conf file containing the application HTTPS virtual host configuration with the configuration block shown below:

      <VirtualHost 127.0.0.1:443 _default_:443>
        ServerAlias *
        DocumentRoot /opt/bitnami/projects/APPNAME/public
        SSLEngine on
        SSLCertificateFile "/opt/bitnami/apache2/conf/bitnami/certs/server.crt"
        SSLCertificateKeyFile "/opt/bitnami/apache2/conf/bitnami/certs/server.key"
        <Directory "/opt/bitnami/projects/APPNAME/public">
          Options -Indexes +FollowSymLinks -MultiViews
          AllowOverride All
          Require all granted
        </Directory>
      </VirtualHost>
      
  • Finally, restart the Apache server:

    $ sudo /opt/bitnami/ctlscript.sh restart apache
    

You can now verify that the example application is working by visiting its URL using your browser at http://SERVER-IP/. Here is an example of what you might see:

Symfony welcome page

Configuration

Before using the example application, here are a few important points to consider:

  • To secure your application, modify the encryption keys in the .env file. Ideally, use a key that’s 32 characters or longer in length and not guessable.

    APP_SECRET="cf05b596287d41e11a9ca958ad289e00"
    

    On Linux, you can use a command like pwgen 32 to generate a 32-character random key. On Windows, you can use a tool like PWGen.

  • If your application will use a database, edit the database settings in the .env file.

    DATABASE_URL="mysql://db_user:db_password@127.0.0.1:3306/db_name"
    

    MySQL support is already available by default. If you plan to use PostgreSQL, enable the pdo_pgsql extension in the /opt/bitnami/php/etc/php.ini file.

    extension=pdo_pgsql
    

Approach B: Self-contained Bitnami installations

The Symfony framework is installed in the frameworks/symfony directory in the installation directory. This directory includes an example application. Application configuration files are in the conf/ directory and the main index.php file is stored in the web/ directory. In this guide, you will learn how to enable the Symfony project and how to configure it. In this guide you will learn how to enable and configure a Symfony project.

Activation and Testing

To enable the example application, edit the Apache configuration file at /opt/bitnami/apache2/conf/bitnami/bitnami-apps-prefix.conf and uncomment the following line

Include "/opt/bitnami/frameworks/symfony/conf/httpd-prefix.conf"

Then, restart the Apache server.

$ sudo /opt/bitnami/ctlscript.sh restart apache

You can now verify that the example application is working by visiting its URL using your browser at http://SERVER-IP/symfony/.

Configuration

Before using the example application, here are a few important points to consider:

  • To secure your application, modify the encryption keys in the .env file. Ideally, use a key that’s 32 characters or longer in length and not guessable.

    On Linux, you can use a command like pwgen 32 to generate a 32-character random key. On Windows, you can use a tool like PWGen.

  • If your application will use a database, edit the database settings in the .env file.

    DATABASE_URL="mysql://db_user:db_password@127.0.0.1:3306/db_name"
    

    MySQL support is already available by default. If you plan to use PostgreSQL, enable the php_pdo_pgsql extension in the /opt/bitnami/php/etc/php.ini file.

    extension=php_pdo_pgsql
    
  • To move the Symfony application such that it is available at the root URL of the server (without the /symfony URL suffix), follow these steps:

    • Edit the /opt/bitnami/frameworks/symfony/conf/httpd-prefix.conf file so that it looks like this:

      DocumentRoot "/opt/bitnami/frameworks/symfony/public/"
      #Alias /symfony/ "/opt/bitnami/frameworks/symfony/public/"
      #Alias /symfony "/opt/bitnami/frameworks/symfony/public"
      Include "/opt/bitnami/frameworks/symfony/conf/httpd-app.conf"
      
    • Edit the /opt/bitnami/frameworks/symfony/conf/httpd-app.conf file and replace the AllowOverride None directive with the AllowOverride All directive:

      AllowOverride All
      
    • Restart the Apache server:

      $ sudo /opt/bitnami/ctlscript.sh restart apache
      

    You should now be able to access the example application at the root URL of your server.
