Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.

A Ubuntu 16.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all required PHP modules:

apt-get install php7.0-curl php7.0-gd php7.0-mbstring php7.0-mysql libapache2-mod-php7.0 php7.0-mcrypt php7.0-bz2 php7.0-zip php7.0-json

You’ll need to also adjust some settings in your php.ini. Open up the file and edit these two variables:

nano /etc/php/7.0/apache2/php.ini

Also, add/modify the following settings:

date.timezone = 'America/New_York'
max_execution_time = 300
max_input_time = 600
memory_limit = 256M
post_max_size = 100M
upload_max_filesize = 100M
short_open_tag = Off
safe_mode = Off
magic_quotes_gpc = Off
magic_quotes_runtime = Off
session.cookie_httponly = On
extension = xapian.so

Step 3. Installing Chamilo.

First thing to do is to go to Chamilo’s download page and download the latest stable version of Chamilo, At the moment of writing this article it is version 1.10:

wget https://github.com/chamilo/chamilo-lms/archive/v1.10.0.zip

Unpack the Chamilo archive to the document root directory on your server:

unzip v1.10.0.zip
mv chamilo-lms-1.10.0/ /var/www/html/chamilo

We will need to change some folders permissions:

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

Step 4. Configuring MariaDB for Chamilo.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:

mysql_secure_installation

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 Chamilo. 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 Chamilo installation:

CREATE DATABASE chamilodb;
CREATE USER 'chamilouser'@'localhost' IDENTIFIED BY 'Pa$$worD123';
GRANT ALL PRIVILEGES ON chamilodb.* TO 'chamilouser'@'localhost';
FLUSH PRIVILEGES;
quit

Step 5. Configuring Apache web server for Chamilo.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘chamilo.conf’ on your virtual server:

touch /etc/apache2/sites-available/chamilo.conf
ln -s /etc/apache2/sites-available/chamilo.conf /etc/apache2/sites-enabled/chamilo.conf
nano /etc/apache2/sites-available/chamilo.conf

Add the following lines:


ServerAdmin [email protected]
DocumentRoot /var/www/html/chamilo
ServerName your-domain.com
ServerAlias www.your-domain.com

Options FollowSymLinks
AllowOverride All

ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
