Prerequsite

Before proceeding with the download and installation of Elgg it is necessary to run a web server correctly. That is, with Apache, PHP, and MySQL. A very simple way to mount it on Windows 10 is by using Xampp.

Downloading Elgg.

This is an open-source platform that can be downloaded for free from this link. Once you have downloaded the file, please unzip it in the Xammp web pages directory. Please see the screenshot below.

Creating a new database for Elgg

To be able to run our Elgg protection correctly it is imperative to create a new database. With this in mind, enter phpMyAdmin from the Xampp Dashboard. Please enter the following address in your web browser: http://localhost/phpmyadmin/. Once there, please create the database and assign it the name of your preference.

Configuring and installing Elgg on your local web server

After creating the database, it is time to start installing Eggl. With this in mind, please paste the name of the installation folder, after the localhost in the web browser. For example:http://localhost/elgg-3.3.8. The installation wizard will be displayed immediately. Press Next to continue.

On the next screen, the wizard will check the prerequisites for installation. If everything is in order, then you can continue the process by pressing Next.

On the next screen, it is time to configure some parameters. First, set the username and password. Since we are in a secure environment, use the root username, and leave the password field blank. Additionally, add the name of the previously created database.

Scroll down and paste the address of the folder where you will save the projects.

After installing the database it is time to configure the site. With this intention, assign the name of the site and the type of access. Optionally you can enter an email address to communicate with the users.

We’re getting to the final part of the installation process. Now it’s time to create the site administrator account. To do this, assign the name that will display the account. Then set up the email account and password for the account.

The process is finally complete. Please click on Go to the site to launch Elgg.

From now on you only have to start exploring the functions of this platform.

Elgg requires MySQL, PHP, and a web server. So we need to install LAMP stack before Elgg installation.

i: Install Apache webserver

dnf install httpd -y

Now start and enable apache service on boot.

systemctl start httpd

systemctl enable httpd

Adding apache ports in the firewall.

firewall-cmd --add-port={80/tcp,443/tcp} --permanent
firewall-cmd --reload

Start and enable MYSQL service on boot.

systemctl start mysqld
systemctl enable mysqld

Complete MYSQL installation

mysql_secure_installation

Set root password? [Y/n] Y 
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

Step 2: Create a MySQL database for Elgg

Log in to the MySQL console using below command and type your password when asked.

mysql -u root -p

now create a new database

CREATE DATABASE elgg;

Now create a new MySQL user and grant it privileges on the created database. You can replace username and password with the username and password of your own choice.

CREATE USER 'database_user'@'localhost' IDENTIFIED BY 'user_password';
GRANT ALL PRIVILEGES ON database_name.* TO 'database_user'@'localhost';
FLUSH PRIVILEGES;

Exit the MySQL console.
