sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

If you see the page above, then Apache2 is successfully installed.

Step 2: Install PHP 7.2 and Related Modules

Symfony is a PHP based framework and PHP is required. However, PHP 7.2 may not be available in Ubuntu default repositories. To run PHP 7.2 on Ubuntu 16.04 and previous, you may need to run the commands below:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.2

sudo apt update

Next, run the commands below to install PHP 7.2 and related modules.

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-sqlite3 php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-ldap php7.2-gd php7.2-bcmath php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open PHP default configuration file for Apache2.

sudo nano /etc/php/7.2/apache2/php.ini

The lines below is a good settings for most PHP based CMS. Update the configuration file with these and save.

allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Everytime you make changes to PHP configuration file, you should also restart Apache2 web server. To do so, run the commands below:

sudo systemctl restart apache2.service

Now that PHP is installed, to test whether it’s functioning, create a test file called phpinfo.php in Apache2 default root directory. ( /var/www/html/)

sudo nano /var/www/html/phpinfo.php

<?php phpinfo( ); ?>

Next, open your browser and browse to the server’s hostname or IP address followed by phpinfo.php

sudo apt install curl git
curl -sS  | sudo php -- --install-dir=/usr/local/bin --filename=composer

After installing Composer above, change Apache2 home directory and download Symfony packages into a new project folder called symfony5.

cd /var/www/
sudo composer create-project symfony/skeleton symfony5

Then run the commands below to set the correct permissions for Symfony root directory and give Apache2 control.

sudo chown -R www-data:www-data /var/www/symfony5/
sudo chmod -R 755 /var/www/symfony5/

Step 4: Configure Apache2

Finally, configure Apahce2 site configuration file for Symfony. This file will control how users access Symfony content. Run the commands below to create a new configuration file called symfony.conf

sudo nano /etc/apache2/sites-available/symfony.conf

Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.

<VirtualHost *:80>
     ServerAdmin [email protected]
     DocumentRoot /var/www/symfony5/public
     ServerName example.com
     ServerAlias www.example.com

     <Directory /var/www/symfony5/public/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted
     </Directory>

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

Save the file and exit.

Step 5: Enable the Symfony

After configuring the VirtualHost above, enable it by running the commands below

sudo a2ensite symfony.conf
sudo systemctl restart apache2.service

Then open your browser and browse to the server domain name or server IP address of the host. You should then see Symfony 5 homepage.
