In This Article
• A fresh Ubuntu 20.04 on the Atlantic.net Cloud Platform
• A valid domain name pointed to your server IP
• A root password configured on your server
Step 1 – Install Apache, MariaDB and PHP
Elgg runs on Apache web server, is written in PHP, and uses MySQL/MariaDB as a database backend, so you will need to install the Apache, MariaDB, PHP and other required PHP extensions to your server. You can install all of them with the following command:
apt-get install apache2 mariadb-server php libapache2-mod-php php-common php-sqlite3 php-curl php-intl php-mbstring php-xmlrpc php-mysql php-gd php-xml php-cli php-zip unzip wget -y
After installing all the packages, edit the php.ini file and change some recommended settings.
Change the following values:
max_execution_time = 300 memory_limit = 512M upload_max_filesize = 100M date.timezone = Asia/Kolkata
Save and close the file, then restart the Apache service to apply the configuration changes.
systemctl restart apache2
Step 2 – Create a Database for Elgg
Next, you will need to create a database and user for Elgg. First, log in to MySQL shell with the following command:
Once logged in, create a database and user with the following command:
CREATE DATABASE elgg; CREATE USER 'elgg'@'localhost' IDENTIFIED BY 'secure-password';
Next, grant all the privileges to the elgg database with the following command:
GRANT ALL ON elgg.* TO 'elgg'@'localhost' IDENTIFIED BY 'secure-password' WITH GRANT OPTION;
Next, flush the privileges and exit from the MariaDB shell with the following command:
FLUSH PRIVILEGES; EXIT;
At this point, the MariaDB database is created for Elgg.
Step 3 – Install Elgg
First, download the latest version of Elgg from its official website using the following command:
Once the download is completed, unzip the downloaded file with the following command:
Next, move the extracted directory to the Apache root directory:
mv elgg-3.3.13 /var/www/html/elgg
Next, create a data directory and set proper ownership and permissions to the Elgg directory:
mkdir /var/www/html/data chown -R www-data:www-data /var/www/html/elgg chown -R www-data:www-data /var/www/html/data chmod -R 755 /var/www/html/elgg
Once you are finished, you can proceed to the next step.
Step 4 – Configure Apache for Elgg
Next, you will need to configure Apache to serve Elgg. You can configure it by creating a new Apache virtual host configuration file:
Add the following lines:
<VirtualHost *:80> ServerAdmin email@example.com DocumentRoot /var/www/html/elgg/ ServerName elgg.example.com Options FollowSymLinks AllowOverride All ErrorLog /var/log/apache2/elgg-error_log CustomLog /var/log/apache2/elgg-access_log common </VirtualHost>
Save and close the file, then enable the virtual host and Apache rewrite module with the following command:
a2ensite elgg.conf a2enmod rewrite
Finally, restart the Apache service to apply the changes:
systemctl restart apache2
