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 tutorial will guide you through the process of installing Elgg on a Ubuntu 18.04 VPS.


  • A fresh Vultr Cloud Compute instance with Ubuntu 18.04 and root access.

Step 1: Install Apache, MySQL, and PHP

Elgg requires MySQL, PHP, and a web server. Before you can install Elgg, you will need to install the Apache web server, MySQL, and PHP.

Update the repository list.

apt-get update

Install the Apache web server.

apt-get install apache2 -y

Install MySQL.

apt-get install mysql-server -y

Complete the MySQL installation by executing the following command.


During the installation, you will be asked to enter a root password. Enter a secure password. This will be the MySQL root password.

Would you like to setup VALIDATE PASSWORD plugin? [Y/N] N

New password: password

Re-enter new password: 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

Install PHP 7.2, as well as the PHP modules required by Elgg.

apt-get install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-sqlite3 php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-xml php7.2-cli php7.2-zip -y

Step 2: Create a MySQL database for Elgg

Elgg will require a MySQL database. Log into the MySQL console.

mysql -u root -p

When prompted for a password, enter the MySQL root password you set in step 1. Once you are logged in to the MySQL console, create a new database.


Create a new MySQL user and grant it privileges to the newly created database. You can replace username and password with the username and password of your choice.

GRANT ALL PRIVILEGES on elgg.* to 'username'@'localhost' identified by 'password';


Exit the MySQL console.


Step 3: Download and Install Elgg

Download the latest version of Elgg.

cd /var/www/html

rm -r index.html


Unzip the downloaded archive and move the files to the root of the Apache web server.

apt install unzip


mv ./elgg-2.3.7/* . && rm && rm -r elgg-2.3.7

Create a data directory for Elgg.

sudo mkdir -p /var/www/html/data

Set the appropriate file permissions.

sudo chown -R www-data:www-data /var/www/html/

sudo chmod -R 755 /var/www/html/

Step 4: Configure Apache for Elgg

Elgg requires the Apache rewrite module. Enable the Apache rewrite module.

sudo a2enmod rewrite

Create an Apache configuration file for the Elgg installation.

sudo nano /etc/apache2/sites-available/elgg.conf

Paste the following snippet to the file, replacing with your own domain name.

<VirtualHost *:80>

     DocumentRoot /var/www/html/


     <Directory /var/www/html/>

          Options FollowSymlinks

          AllowOverride All

          Require all granted


     ErrorLog ${APACHE_LOG_DIR}/error.log

     CustomLog ${APACHE_LOG_DIR}/access.log combined


Enable the configuration and restart the Apache server.

 sudo a2ensite elgg.conf

 sudo systemctl restart apache2.service

Step 5: Complete the Elgg Installation

At this point, you can proceed to the Elgg browser installer to finish the installation. Open a browser window on your computer and navigate to your domain name. This will launch the Elgg browser installer. Proceed through the installer to the Database Installation step. Here, enter the credentials of the MySQL database you created in Step 2 and proceed to the next step.

On the next step, enter a site name and email address of your choice. In the Site URL field, enter your domain name. In the Data Directory field, enter /var/www/html/data and proceed to the next step.

Next, enter the administrator credentials of your choice and press Next. At this point the installation is complete.

To log into the administrator panel, navigate to the following URL.


You have successfully installed Elgg on a Ubuntu 18.04 VPS and can begin setting up your own social network.
