Moodle

Moodle is a free and open-source e-learning software platform, written in PHP.

This article describes how to set up the Moodle server.

Installation

You will need a working web server (e.g. Apache HTTP Server), a database (e.g. MySQL or PostgreSQL) and have PHP configured.

Be aware a compatible PHP version is required.

There is also an AUR package moodle^AUR for the installation.

Either you can use this way:

Download the most current version of Moodle from https://download.moodle.org/ - this installation was done with 2.3.1+, and there may be minor changes to the install routine in later versions.

Unzip it into /srv/http:

# tar xzvf moodle-latest-23.tgz -C /srv/http

Make it read/writeable by Apache:

# chown -R http:http /srv/http/moodle

Configuration

Preconfiguration

Some changes need to be made to the default setup so Moodle will work.

File access

Add /srv to /etc/php/php.ini:

open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/srv/

This allows PHP to access the /srv/moodledata directory.BBS#80782

Create the MoodleData Directory

This needs to be readable and writeable by Apache:

# mkdir /srv/moodledata
# chown http:http /srv/moodledata

Configure PHP extension

Uncomment the following lines in /etc/php/php.ini (remove the semicolon from the start of the line):

extension=curl
extension=gd
extension=gettext
extension=iconv
extension=intl
extension=mysqli
extension=soap
extension=xmlrpc
extension=zip

Restart Apache

You now need to restart Apache's httpd.service to make these changes current. Note that if you get any errors while installing Moodle, and make subsequent changes, you will need to restart Apache after each set of changes.

MariaDB

If you are using MariaDB and the moodle installer complains about the wrong version of MySQL, edit config.php in /srv/http/moodle

$CFG->dbtype    = 'mariadb'; 
$CFG->dblibrary = 'native';

You will also need to create some tables so that Moodle can connect to it and modify it:

MariaDB[(none)] > CREATE USER 'moodleuser'@'localhost' IDENTIFIED BY 'yourpassword';
MariaDB[(none)] > GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO 'moodleuser'@'localhost';
MariaDB[(none)] > FLUSH PRIVILEGES;
MariaDB[(none)] > exit;

Configure a cron job

Per maintenance requirements, you need to configure a cron job to run regularly on your site.

Check Cron page to install a cron implementation. After that, edit your {{ic[/etc/crontab}} file and add the following:

* * * * *    /usr/bin/php /path/to/moodle/admin/cli/cron.php >/dev/null

Change the path to your Moodle installation directory.

Application configuration

Go to http://localhost/moodle/install.php - this starts the Moodle installer. There then follows a sequence of configuration screens, most of which should be left at the defaults:

Select the language
You should pass the first page of tests (PHP Settings).
Leave the default locations as they are. An error here is likely to be a data directory problem - check the directory exists, that it has the right ownership and that open_basedir in /etc/php/php.ini is set correctly.
On the MySQL Screen, enter the user (root) and that user's password in the screen. If you get an error here, go to the test.php created when you set up the LAMP stack and check mysql is working, and also check the passwords.
On the Environment screen, you should pass all the tests - if not the errors give you a clue what is missing - an uninstalled program or a failure to uncomment one of the lines in /etc/php/php.ini
If you are English, you do not need to download language packs.
If the config.php has failed - probably because of lack of write access to the moodle subdirectory - the most likely reason is the ownership of the /srv/http/moodle structure, which should be http:http - this was set earlier but you might have skipped that bit.
The remainder of the install should be automatic. It takes 2 or 3 minutes on my computer to set up all the SQL Databases and so on.
The final page allows you to set up the administrator user for Moodle. You need to enter a password, name and set the country as a bare minimum. Do not forget the password !

Happy Moodling !
