How to Install Symfony 5 with Nginx on Ubuntu Linux

Install Nginx HTTP Server

Install Nginx on your Ubuntu system to create a web server that works well with Symfony. You’ll use your terminal to run a couple of commands. First, update your list of available software with `sudo apt update`, and then install Nginx itself by running `sudo apt install nginx`.

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

Symfony needs PHP to work, so you must install PHP 7.2-FPM and its necessary modules on Ubuntu. If your Ubuntu version doesn’t have PHP 7.2-FPM ready, first run `sudo apt-get install software-properties-common` and then `sudo add-apt-repository ppa:ondrej/php` to add the right source.

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

Composer is a tool that helps manage Symfony and its parts. To download the latest Symfony version, you first need to install Composer on your Ubuntu machine. The commands shown will add Composer to your system so you can manage Symfony’s needs easily. Start by running `sudo apt install curl`.

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

You need to configure Nginx so it knows how to handle requests for your Symfony site. This involves making a new file that tells Nginx where your Symfony files are and how to show them to visitors. Create this file by running `sudo nano /etc/nginx/sites-available/symfony` and then paste in the correct settings.

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

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

Once you have set up the Nginx configuration for your Symfony site, you need to turn it on. This means creating a link from the place where all possible configurations are stored to the place where active ones are kept. Use `sudo ln -s /etc/nginx/sites-available/symfony /etc/nginx/sites-enabled/` to make the link, then restart Nginx with `sudo systemctl restart nginx.service`.

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.
