Symfony 2 Joboard: Getting Started

113

In each chapter, new functions will be added to the application, and we will use this approach to gradually introduce Symfony into the framework, and learn about the best practices in web development on Symfony.

In this part, you will not write the code. Instead, you will configure the development development environment.

Configuring the Development Environment

- Advertisement -

First of all you need to check that your computer has the appropriate software for web development. As an operating system, we will use Ubuntu 12. Of the software at least, we need an Apache web server, MySQL and PHP 5.3.3 or later. For Windows, I recommend installing XAMPP , there are all the libraries and the environment for the developer is already set up. Also, instead of the Apache server, you can use the built-in server in php 5.4 and higher, as it will be shown below.

Installing Apache as the primary web server

Go to the terminal and type:

sudo apt-get install apache2

then enable the Apache mod-rewrite module :

sudo a2enmod rewrite

Installing MySQL server

sudo apt-get install mysql-server mysql-client

Installing PHP

sudo apt-get install php5 libapache2-mod-php5 php5-mysql

Installing an Intl extension :

sudo apt-get install php5-intl

Now you need to restart the Apache service:

sudo service apache2 restart

Install Symfony 2

The first thing to do is prepare a directory for the web server where you want to install a new project. Let’s call it the joboard: /var/www/joboard(do not create the directory).

In order to download the latest version of Symfony2 to this directory, we need to install a package manager for PHP – Composer . The framework itself and all the libraries necessary for it will be downloaded automatically through this utility.

Composer is a dependency manager for third-party libraries for PHP, which can also be used to download Symfony 2 Standard Edition.

Now let’s install Composer by running the command:

php -r "readfile('https://getcomposer.org/installer');" | php
mv composer.phar /usr/local/bin/composer

or if for some reason it does not work for you, you can install it like this:

curl -s https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

And now the installation of Symfony2 Standard Edition (you need to go to the directory /var/www/):

cd /var/www/
composer create-project symfony/framework-standard-edition joboard "2.5.*"

During the installation, you will need to answer a few questions, just press Enter all the time.

Web Server Configuration

The embedded PHP server

You can run the project on a symphony, without setting up a virtual host to do this, go to the web directory of your project and run the built-in local server in PHP: php -S localhost: 8000, then go to http: // localhost: 8000

The second and simpler way is to go to the project’s root directory and run a command that will launch the exact same server, only you do not need to specify in the address bar app_dev.php:

php app/console server:run

Good practice in web development is placed in the root directory of the web , only those files that need to be accessed in the web browser, it can be: styles, JavaScript files or images. By default, it is recommended that you store these files in the project’s web symfony subdirectory .

To configure Apache for your new project, create a virtual host. To do this, go to your terminal and enter the following command:

sudo nano /etc/apache2/sites-available/joboard.local.conf

Now we have a file called joboard.local . Insert the description of the virtual host (see below) inside the created file, and then press CTRL + O and Enter to save it, then CTRL + X to exit the editor.

<VirtualHost *:80>
    ServerName joboard.local
    DocumentRoot /var/www/joboard/web
    DirectoryIndex app.php
    ErrorLog /var/log/apache2/joboard-error.log
    CustomLog /var/log/apache2/joborad-access.log combined
    <Directory "/var/www/joboard/web">
        AllowOverride All
        Allow from All
    </Directory>
</VirtualHost>

The domain name joboard.local , is used in the Apache configuration and must be declared locally. If you work in Linux, then you can register a local domain in a file /etc/hosts. If you are running Windows, this file is located in the directory C:\Windows\System32\drivers\etc\. Open this file and add the following line:

127.0.0.1 joboard.local

If you want the domain name to work on the local computer, you need to enable the newly created virtual host and restart Apache. So open the terminal and type:

sudo a2ensite joboard.local.conf
sudo service apache2 restart

Symfony comes with a visual configuration tester, it will help you make sure that your web server and PHP are properly configured to use Symfony. Use the following URL to verify the configuration:http: //joboard.local/config.php

The screenshot shows that for the normal operation of Symfony, the framework defines a number of requirements. Below is a list of actions to solve all the problems noted.

Change permissions on the directory app/cacheand app/log:

HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs

Set ACL if you do not already have it:

sudo apt-get install acl

Set the parameter date.timezonein php.ini

sudo nano /etc/php5/apache2/php.ini

If you get an error with setfacl, try the following commands:

rm -rf app/cache/*
rm -rf app/logs/*

HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
sudo chmod +a "$HTTPDUSER allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs

Find the parameter date.timezonefor the section [date]and set it to your time zone. After that, delete the “;” at the beginning of the line.

# etc/php5/apache2/php.ini

date.timezone = Europe/Minsk

Set the parameter short_open_tagto the value Offin the same php.ini file

#/etc/php5/apache2/php.ini

short_open_tag = Off

Install and enable PHP accelerator (APC recommended)

sudo apt-get install php-apc
sudo service apache2 restart

After restarting Apache, open the browser window and type http: //joboard.local/app_dev.php . You should see the following page:
