Install Elgg on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install Elgg on Ubuntu 18.04 LTS. For those of you who didn’t know, Elgg is an open-source social networking engine that allows the creation of social environments such as campus social networks and internal collaborative platforms for organizations. Elgg offers a number of social networking features including microblogging, messaging, file-sharing, and groups.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation Elgg Social Networking Platform on an Ubuntu 18.04 Bionic Beaver server.


  • A server running one of the following operating systems: Ubuntu 18.04 and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Elgg on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB, and PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also, install all required PHP modules:

apt-get install php7.1-cli php7.1-mbstring php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Installing Elgg on Ubuntu 18.04.

The first thing to do is to go to Elgg’s download page and download the latest stable version of Elgg, At the moment of writing this article it is version 2.3.10:


Unpack the Elgg archive to the document root directory on your server:

mv /elgg-2.3.10/ /var/www/html/elgg/

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/elgg/
chmod -R 755 /var/www/html/elgg/

Step 4. Configuring MariaDB for Elgg.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:


Configure it like this:

- Set root password? [Y/n] y
- 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

Next, we will need to log in to the MariaDB console and create a database for the Elgg. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Elgg installation:

create database elggdb;
GRANT ALL PRIVILEGES ON elggdb.* TO 'elgguser'@'localhost' IDENTIFIED BY 'Y0UR-PASSW0RD';
flush privileges;

Step 5. Configuring Apache web server for Elgg.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘elgg.conf’ on your virtual server:

touch /etc/apache2/sites-available/elgg.conf
ln -s /etc/apache2/sites-available/elgg.conf /etc/apache2/sites-enabled/elgg.conf
nano /etc/apache2/sites-available/elgg.conf

Add the following lines:

<VirtualHost *:80>
DocumentRoot /var/www/html/elgg/
<Directory /var/www/html/elgg/>
Options FollowSymLinks
AllowOverride All
ErrorLog /var/log/apache2/
CustomLog /var/log/apache2/ common

Save and close the file. Restart the apache service for the changes to take effect:

sudo a2ensite elgg.conf
sudo a2enmod rewrite
sudo systemctl restart apache2

Step 6. Accessing Elgg.

Elgg Social Networking Platform will be available on HTTP port 80 by default. Open your favorite browser and navigate to or http://server-ip/install.php and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
