Steps To Install and Configure Flarum on Ubuntu 22.04

At this point, you can log in to your server as a non-root user with sudo privileges and follow the steps below.

Step 1 – Configure PHP for Flarum

At this point, you need to install some additional PHP extensions for Flarum on Ubuntu 22.04 with the following command:

sudo apt install php-{bcmath,xml,fpm,mysql,zip,intl,ldap,gd,cli,bz2,curl,mbstring,pgsql,opcache,soap,cgi}

Then, you need to make some configuration changes in the php.ini file. Open the following file with your favorite text editor, here we use the vi editor:

sudo vi /etc/php/8.1/apache2/php.ini

Find the following lines and make changes to them as shown below:

memory_limit = 256M
max_execution_time = 300
upload_max_filesize = 150M
allow_url_fopen = On
file_uploads = On

When you are done, save and close the file.

Step 2 – Create Flarum Database User

In this step, you need to log in to your MariaDB console and create a Flarum database and a database user. To log in to your MariaDB shell, run the following command:

sudo mariadb -u root -p

Enter your password and run the following command to create a Flarum database:

MariaDB [(none)]> CREATE DATABASE flarumdb;

Then, run the following command on Ubuntu 22.04 to create your Flarum database user and set a password for it:

MariaDB [(none)]> CREATE USER 'flarumuser'@'localhost' IDENTIFIED BY 'password';

Next, grant all the privileges to the database user by using the command below:

MariaDB [(none)]> GRANT ALL PRIVILEGES ON flarumdb.* TO 'flarumuser'@'localhost';

Finally, flush the privileges and exit from the MariaDB shell with the following commands:

MariaDB [(none)]> EXIT

Step 3 – Flarum Installation on Ubuntu 22.04

At this point, we will use the composer to download and install the Flarum discussion forum.

First, you need to create a working directory under the /var/www/html/ directory for Flarum. To do this, you can run the following command in your terminal:

 sudo mkdir /var/www/html/flarum

Then, switch to your Flarum directory:

cd /var/www/html/flarum

Now use the Composer to download and install the latest Flarum on Ubuntu 22.04:

sudo composer create-project flarum/flarum

Step 4 – Apache Configuration for Flarum

At this point, you need to configure your Apache to serve Flarum on Ubuntu 22.04.

First, you need to create an Apache virtual host file with your favorite text editor, here we use vi:

ErrorLog /var/log/apache2/flarum-error_log
CustomLog /var/log/apache2/flarum-access_log common


Note: Remember to change the server name with your domain name.

When you are done, save and close the file.

Then, you need to enable your Flarum site with the command below:

sudo a2ensite flarum

Also, you need to disable the default configuration file by using the following command:

sudo a2dissite 000-default.conf

Next, enable the rewrite module for Apache and restart it by using the following commands:

# sudo a2enmod rewrite
# sudo systemctl restart apache2

Step 5 – Configure Firewall

If you have a running UFW firewall, you need to open the following ports through the firewall:

# sudo ufw allow 80/tcp
