To get started with installing FluxBB, follow the steps below:

Install Apache2

FluxBB is PHP-based and requires a webserver. The most popular open-source web server in use today is Apache2. To install Apache2, run the commands below:

sudo apt update
sudo apt-get install apache2

After installing Apache2, the commands below can be used to stop, start and enable the Apache2 service to always start up with the server boots.

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

To test the Apache2 setup, open your browser and browse to the server hostname or IP address, and you should see the Apache2 default test page as shown below. When you see that, then Apache2 is working as expected.

apache2 ubuntu install

Install MySQL Database Server

A MySQL database server is a great place to start when looking at open-source databases to use with FluxBB. To install MySQL run the commands below.

sudo apt-get install mysql-server mysql-client

After installing MySQL, the commands below can stop, start and enable MySQL service to start up when the server boots.

Run these on Ubuntu

sudo systemctl stop mysql.service
sudo systemctl start mymsql.service
sudo systemctl enable mysql.service

After that, run the commands below to secure the MySQL server by creating a root password and disallowing remote root access.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

  • Enter current password for root (enter for none): Just press the Enter
  • Set root password? [Y/n]: Y
  • New password: Enter password
  • Re-enter new password: Repeat password
  • Remove anonymous users? [Y/n]: Y
  • Disallow root login remotely? [Y/n]: Y
  • Remove test database and access to it? [Y/n]:  Y
  • Reload privilege tables now? [Y/n]:  Y

Restart MySQL server

To test if MySQL is installed, type the commands below to log on to the server.

sudo mysql -u root -p

Then type the password you created above to sign on. If successful, you should see MySQL welcome message.

Install PHP 7.2 and Related Modules

PHP 7.2 may not be available in Ubuntu default repositories. To install it, you will have to get it from third-party repositories.

Run the commands below to add the below third party repository to upgrade to PHP 7.2

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-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-pgsql php7.2-xml php7.2-cli php7.2-imagick php7.2-bcmath php7.2-gmp php7.2-zip

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

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

Then save the changes on the following lines below in the file. The value below is an ideal setting to apply in your environment.

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

After making the change above, please save the file and close it.

To restart Apache2, run the commands below

sudo systemctl restart apache2.service

To test PHP 7.2 settings with Apache2, create a phpinfo.php file in the Apache2 root directory by running the commands below

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

Then type the content below and save the file.

<?php phpinfo( ); ?>

Save the file. Then browse to your server hostname followed by /phpinfo.php

Run the commands below to log on to MySQL. When prompted for a password, type the root password you created above.

sudo mysql -u root -p

Then create a database called fluxbb


Create a database user called fluxbbuser with a new password

CREATE USER 'fluxbbuser'@'localhost' IDENTIFIED BY 'new_password_here';
