In this tutorial, we will show you how to install Elgg on Ubuntu 20.04 LTS. For those of you who didn’t know, It is highly customizable with a simple and powerful user interface that makes it easy to build and manage content online over the web. Elgg is managed by the Elgg Foundation, which is a nonprofit organization.
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 through the step-by-step installation of the Elgg open source social networking engine on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
Install Elgg on Ubuntu 20.04 LTS Focal Fossa
Step 1. First, make sure that all your system packages are up-to-date by running the following
apt commands in the terminal.
sudo apt update sudo apt upgrade
Step 2. Install the LAMP stack.
A Ubuntu 20.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here.
Step 3. Installing Elgg on Ubuntu 20.04.
Now we run the commands below to download the latest version of Elgg:
wget https://elgg.org/download/elgg-3.3.20.zip unzip elgg-*.zip sudo mv elgg-*/ /var/www/html/elgg/
We will need to change some folders permissions:
sudo mkdir /var/www/html/data sudo chown -R www-data:www-data /var/www/html/elgg/ sudo chown -R www-data:www-data /var/www/html/data sudo 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 elgg; CREATE USER 'elgg'@'localhost' IDENTIFIED BY 'your-secure-password'; GRANT ALL ON elgg.* TO 'elgg'@'localhost' IDENTIFIED BY 'secure-password' WITH GRANT OPTION; FLUSH PRIVILEGES; EXIT;
Step 5. Configuring Apache web server for Elgg.
Now we 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> ServerAdmin [email protected] DocumentRoot /var/www/html/elgg/ ServerName your-domain.com ServerAlias www.your-domain.com <Directory /var/www/html/elgg/> Options FollowSymLinks AllowOverride All Order allow,deny allow from all </Directory> ErrorLog /var/log/apache2/your-domain.com-error_log CustomLog /var/log/apache2/your-domain.com-access_log common </VirtualHost>
Now, we can restart the Apache webserver so that the changes take place:
sudo a2enmod rewrite sudo a2ensite elgg.conf sudo systemctl restart apache2.service
Step 6. Set up HTTPS.
We should enable a secure HTTPS connection on PrestaShop. We can obtain a free TLS certificate from Let’s Encrypt. Install Let’s Encrypt client (certbot) from Ubuntu 20.04 repository:
sudo apt install certbot python3-certbot-apache
Next, run the following command to obtain a free TLS certificate using the Apache plugin:
sudo certbot --apache --agree-tos --redirect --staple-ocsp --email [email protected] -d example.com
If the test is successful, reload Apache for the change to take effect:
sudo apache2ctl -t sudo systemctl reload apache2
Step 7. Accessing Elgg Web Interface.
Elgg will be available on HTTP port 80 by default. Open your favorite browser and navigate to
https://server-ip-address/ 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.
