How to Install Elgg on Alpine Linux Latest

This tutorial will guide you through the steps to install Elgg, a powerful open-source social networking engine, on Alpine Linux, a lightweight and secure operating system.

Prerequisites

Before proceeding with the installation, make sure the following prerequisites are met:

• A running Alpine Linux machine (either physical or virtual)
• Root access or a user with sufficient privileges to install packages
• Internet connectivity to download the necessary packages and dependencies

Step 1: Update and Upgrade

First, update the package index and upgrade the existing packages:

sudo apk update && sudo apk upgrade

Step 2: Install Required Packages

Install the required packages for Elgg:

sudo apk add apache2 mariadb mariadb-client php7-apache2 php7-gd php7-intl php7-mysqli php7-opcache php7-zip php7-xmlrpc php7-mbstring php7-json php7-xml php7-curl

Step 3: Download and Extract Elgg

Download the latest stable release of Elgg from the official website. You can use wget to download the package directly to your Alpine Linux machine:

wget https://elgg.org/getelgg.php?forward=elgg-3.3.16.zip -O elgg.zip

Extract the downloaded package to the root directory of your web server:

sudo unzip elgg.zip -d /var/www/localhost/htdocs/

Now, rename the elgg directory to something more meaningful:

sudo mv /var/www/localhost/htdocs/elgg-* /var/www/localhost/htdocs/elgg

Step 4: Configure MariaDB

Start and enable the MariaDB service:

sudo rc-service mariadb start
sudo rc-update add mariadb

Next, secure your database installation by running the mysql_secure_installation script:

sudo mysql_secure_installation

Follow the instructions to set up a new root password, remove anonymous users, disallow root login remotely, and remove the test database.

Create a new database and user for Elgg:

sudo mysql -u root -p
CREATE DATABASE elgg;
CREATE USER 'elgguser'@'localhost' IDENTIFIED BY 'yourpassword';
GRANT ALL PRIVILEGES ON elgg.* TO 'elgguser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Step 5: Configure Apache

Edit the Apache configuration file to enable the necessary modules and set the document root:

sudo nano /etc/apache2/httpd.conf

Add the following lines at the end of the file:

LoadModule rewrite_module modules/mod_rewrite.so
LoadModule php7_module modules/libphp7.so

<Directory "/var/www/localhost/htdocs">
    AllowOverride All
    Order Allow,Deny
    Allow from all
    Require all granted
</Directory>

DocumentRoot "/var/www/localhost/htdocs/elgg"

Save and close the file.

Restart the Apache service to apply the changes:

sudo rc-service apache2 restart

Step 6: Run the Elgg Installation Script

Open your web browser and visit http://localhost/elgg/install.php. Follow the prompts to complete the installation, using the following database credentials:

• Database Name: elgg
• Database Username: elgguser
• Database Password: yourpassword
• Database Host: localhost

Once the installation is complete, remove the install.php file for security reasons:

sudo rm /var/www/localhost/htdocs/elgg/install.php

Now you can log in to your Elgg site and start customizing it.
