How to Install Symfony 5 with Nginx on Ubuntu Linux

Install Nginx HTTP Server

To install Nginx on Ubuntu for your Symfony project, open your terminal and update your local package list by running sudo apt update. Next, install the 💿 Nginx web server by running the command sudo apt install nginx. Once the installation finishes, Nginx starts automatically and acts as the web server for your new Symfony application.

sudo apt update
sudo apt install nginx

After installing 💿 Nginx, the commands below can be used to stop, start, and enable the Nginx service to always start up with the server boots.

sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Now that Nginx has been installed, browse your browser to the URL below to test whether the web server works.

http://localhost

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

Install PHP 7.2-FPM and Related Modules

To install PHP 7.2-FPM and the required modules for Symfony on Ubuntu, add the Ondřej Surý PHP repository to your system sources if your default repositories do not have version 7.2. Run sudo apt-get install software-properties-common followed by sudo add-apt-repository ppa:ondrej/php, and then proceed to install PHP 7.2-FPM along with your needed extensions.

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

Then update and upgrade to PHP 7.2-FPM

sudo apt update

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

sudo apt install php7.2-fpm 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-FPM, run the commands below to open Nginx's PHP default configuration file.

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

The lines below are a good setting for most PHP-based CMS. Update the configuration file with these and save.

file_uploads = On
allow_url_fopen = On
short_open_tag = On
cgi.fix_pathinfo = 0
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Restarting the Nginx web server whenever you change the PHP configuration file would be best. To do so, run the commands below:

sudo systemctl restart nginx.service

Download Symfony's Latest Release

To download Symfony's latest release on your Ubuntu machine, you first need to install Composer, which is the dependency manager for PHP projects. Start by installing the required tools and curl utility on your system using the terminal command sudo apt install curl git, and then follow the official installer steps to set up Composer globally.

To install Composer on Ubuntu, run the commands below:

sudo apt install curl git
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

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

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

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

Configure Nginx

To configure Nginx for a Symfony 5 project on Ubuntu, create a new server block configuration file inside the sites-available directory. Open your terminal and run the command sudo nano /etc/nginx/sites-available/symfony, then paste your domain name, document root pointing to your project public folder, and PHP-FPM socket settings.

sudo nano /etc/nginx/sites-available/symfony

Replace the highlighted line with your domain name and directory root location.

server {
    listen 80;
    listen [::]:80;

    server_name  example.com www.example.com;
    root   /var/www/symfony5/public;
    index  index.php;
    
    access_log /var/log/nginx/example.com.access.log;
    error_log /var/log/nginx/example.com.error.log;

    client_max_body_size 100M;
  
    autoindex off;

    location / {
    try_files $uri /index.php$is_args$args;
      }

    location ~ .php$ {
         include snippets/fastcgi-php.conf;
         fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
         include fastcgi_params;
         fastcgi_intercept_errors on;
    }
}

Save the file and exit.

Enable the Symfony

To enable your Symfony site in Nginx on Ubuntu, create a symbolic link from your configuration file in sites-available to the sites-enabled directory by running sudo ln -s /etc/nginx/sites-available/symfony /etc/nginx/sites-enabled/. After creating the link, test your configuration for syntax errors and restart the web server with sudo systemctl restart nginx.service to apply the changes.

sudo ln -s /etc/nginx/sites-available/symfony /etc/nginx/sites-enabled/
sudo systemctl restart nginx.service

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

http://example.com/

Symfony 5 framework application is now ready, and you can start working on it.
