How to install Flarum with Nginx on Ubuntu 24.04

Install Nginx HTTP server on Ubuntu

To install the Nginx web server on Ubuntu for your Flarum site, open your terminal and run the commands to update your package list and then install Nginx.

To do that, open the Ubuntu terminal and run the commands below to install the Nginx web server.

sudo apt update
sudo apt install nginx

Once Nginx is installed, the commands below can start, stop, and enable the Nginx web server to start automatically when your server boots up.

sudo systemctl stop nginx
sudo systemctl start nginx
sudo systemctl enable nginx

You can test the Nginx web server by opening your web browser and browsing to the server’s local host or IP address.

http://localhost

When you see “Welcome to nginx!” the Nginx HTTP server has been installed.

Install MariaDB database server on Ubuntu Linux

Your Flarum installation needs a database, so let’s install MariaDB on Ubuntu Linux by opening the terminal and running the update and install commands.

To install and use the MariaDB database server, use the instructions below.

Open the Ubuntu terminal and run the commands below to install the MariaDB database server.

sudo apt update
sudo apt install mariadb-server

Once the MariaDB database server is installed, use the commands below to stop, start, and enable the MariaDB server to start automatically when the server boots.

sudo systemctl stop mariadb
sudo systemctl start mariadb
sudo systemctl enable mariadb

Run the following commands to validate and test if the MariaDB database server is installed successfully.

sudo mariadb

Once you run the commands above, it will log you onto the MariaDB console and display a message similar to the one below.

Welcome to the MariaDB monitor.  Commands end with ; or g.
Your MariaDB connection id is 32
Server version: 10.11.2-MariaDB-1 Ubuntu 23.04

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MariaDB [(none)]> 

The message tells you that the server is installed successfully.

Create a Flarum database

After setting up MariaDB, you need to create a specific database for Flarum, which we’ll call ‘flarumdb’, and set up a user named ‘flarumdbuser’ with full access to it.

As part of the setup, we will create a database named ‘flarumdb‘ and a corresponding user account called ‘flarumdbuser.’

Finally, we’ll grant the flarumdbuser full access to the flarumdb database.

All the database steps above can be done using the commands below:

But first, log on to the MariaDB database server:

sudo mariadb

Then run the commands below to complete the steps:

CREATE DATABASE flarumdb CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
CREATE USER flarumdbuser@localhost IDENTIFIED BY 'type_your_password_here';
GRANT ALL ON flarumdb.* TO flarumdbuser@localhost WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit

Ensure to replace ‘type_your_password_here ‘with your password.

Install PHP-FPM on Ubuntu Linux

Flarum is built with PHP, so you’ll need to install PHP-FPM on Ubuntu Linux along with some essential extensions to make it work correctly.

Run the commands below to install PHP-FPM.

sudo apt install php-fpm php-intl php-mysql php-curl php-cli php-zip php-xml php-gd php-common php-mbstring php-xmlrpc php-json php-sqlite3 php-soap php-zip

Download Flarum files

Now it’s time to download the Flarum application files onto your Ubuntu server, which involves installing Composer and then using it to get the latest release.

You may want to use the GitHub repository to get Flarum’s latest release. Install Composer, Curl, and other dependencies to get started.

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

After installing curl and Composer above, change the directory to the Nginx root directory and download the Flarum packages from Github. Always replace the release number with the latest release.

sudo mkdir -p /var/www/{.cache,.config,flarum}
sudo chown -R www-data:www-data /var/www/{.cache,.config,flarum}
cd /var/www/flarum/
sudo -u www-data composer create-project flarum/flarum .
sudo chown -R www-data:www-data /var/www/flarum/

Once all the steps are done, configure the Nginx webserver to serve the Flarum content.

Run the commands below to create a Nginx virtual host file for Flarum.

sudo nano /etc/nginx/sites-available/flarum.conf

Then, copy and paste the content block below into the Nginx server block.

server {
        listen 80;
        listen [::]:80;
        server_name flarum.example.com;

        root /var/www/flarum/public;
        index index.php;
   
        error_log /var/log/nginx/flarum.error;
        access_log /var/log/nginx/flarum.access;

        include /var/www/flarum/.nginx.conf;

        location ~ .php$ {
            fastcgi_pass unix:/run/php/php8.3-fpm.sock;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
            include snippets/fastcgi-php.conf;
        }
}

Save the file.

Then, run the commands below to enable the virtual host and restart the Nginx server.

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

Setup Let’s Encrypt SSL/TLS for Flarum

To make your Flarum site secure with HTTPS, you should set up a free SSL/TLS certificate using Let’s Encrypt, which works well with the Nginx web server.

Please read the post below for additional resources on installing and creating Let’s Encrypt SSL certificates for Nginx.

How to set up Let’s Encrypt SSL certificate for Nginx on Ubuntu Linux

Once you have restarted the Nginx web server, open your browser and browse to the server hostname or IP address defined in the Nginx server block.

http://flarum.example.com

A Flarum installation wizard page should appear. Enter the forum name database connection info and create an administrator account. Then, click “Install Flarum.“

Your Flarum site should be ready to use.

That should do it!
