Step 1: Install Ubuntu 14.04LTS


Server Edition amd64 Preferred

http://www.ubuntu.com/download

  • Ubuntu Server 14.04LTS amd64 has all the required packages.
  • Ubuntu Server 14.04LTS has some minor differences from 12.04LTS, mainly to the Apache Sites Configuration, now resides at /etc/apache2/sites-available/000-default.conf and the Default Webroot now at /var/www/html/. This document has been updated to reflect those changes.

Step 2: Install Apache/MySQL/PHP

Open up Terminal and install the following;

  •  :22 in the Video
sudo apt-get update

sudo apt-get install apache2 mysql-client mysql-server php5

'It will prompt you to set the root password for mysql - take note of it, you will need it in step 6.

Step 3: Install Additional Software

  • 1:10 in the video
sudo apt-get install graphviz aspell php5-pspell php5-curl php5-gd php5-intl php5-mysql php5-xmlrpc php5-ldap clamav

Restart Apache so that the modules are loaded correctly

sudo service apache2 restart

We will be using Git to install/update the Moodle Core Application

sudo apt-get install git-core

Step 4: Download Moodle

  • 1:55 in the video

Setup your local repository and download Moodle, We will use /opt for this installation.

[Git is what is called a "version control system". Usually software developers, when they create software, have to update their software numerous times. Git allows one to keep track of the updates they make. Basically what we are doing here (according to my understanding) is using Git to selectively download a certain version of software. Should we want to later update the software, things should be fairly easy]

cd /opt

(we will be saving our file in the /opt directory)

sudo git clone git://git.moodle.org/moodle.git


(sudo is the "super user do" command. this command is telling us to get the moodle repository - or index book of all the versions of moodle at the git.org website - and to download it to our computer)

cd moodle

sudo git branch -a

sudo git branch --track MOODLE_27_STABLE origin/MOODLE_27_STABLE

sudo git checkout MOODLE_27_STABLE

We are getting hold of the 27 stable version of moodle.

Step 5: Copy local repository to /var/www/html/

  • 3:05 in the video
sudo cp -R /opt/moodle /var/www/html/

sudo mkdir /var/moodledata

sudo chown -R www-data /var/moodledata

sudo chmod -R 777 /var/moodledata

sudo chmod -R 0755 /var/www/html/moodle

Step 6: Setup MySQL Server

  • 4:45 in the video

First we need to change the default storage engine to innodb

  • You should not need to make innodb the default storage engine anymore, the latest version of Moodle will select it automatically during install. It is always a good idea to make it default anyway.
sudo vi /etc/mysql/my.cnf

Scroll down to the [mysqld] section and under Basic Settings add the following line under the last statement

default-storage-engine = innodb

In order to save my.cnf using the editor, press the Esc (Escape) key, type the following in sequence which will save :w then close the editor :q

:w

:q

Restart MySQL Server for changes to take affect

sudo service mysql restart

Now we need to create the Moodle MySQL User with the correct permissions

Use the password you created in step 1

mysql -u root -p

mysql>
CREATE DATABASE moodle DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Where it says "moodledude" and "passwordformoodledude" you should change to the username and password of your choosing.

mysql>
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO moodledude@localhost IDENTIFIED BY 'passwordformoodledude';
mysql>
quit;

Step 7: Complete Setup

  • 6:40 in the video
  • Note - If you are not comfortable using terminal to create the config.php file that needs to be created when going through the installer, you should temporarily make the webroot writable by doing the following:
sudo chmod -R 777 /var/www/html/moodle

After you have ran the installer and you have moodle setup, you NEED to revert permissions so that it is no longer writable using the below command.

sudo chmod -R 0755 /var/www/html/moodle

Open your browser and go to http://IP.ADDRESS.OF.SERVER/moodle

Follow the prompts selecting:

Database Type

Choose: mysqli

Database Settings

Host server: localhost

Database: moodle

User: moodledude (the user you created when setting up the database)

Password: passwordformoodledude (the password for the user you created)

Tables Prefix: mdl_

Environment Checks

This will indicate if any elements required to run moodle haven't been installed.

Next next next...

follow prompts and confirm installation

Create a Site Administrator Account

Create your moodle user account which will have site administrator permissions.

The password you select has to meet certain security requirements.

Installation Complete

Congrats! You can now start using Moodle!

Don't Forget

If you made the webroot writable, revert permissions

sudo chmod -R 0755 /var/www/html/moodle

System Paths After Install

  • 10:05 in the video

After installing Moodle you should set the system paths.

Navigate to Site Administration > Server > System Paths

Input the following;

Path to Du: /usr/bin/du

Path to Apsell: /usr/bin/aspell

Path to dot: /usr/bin/dot

Save Changes


  • Optional if you do not already have an AntiVirus Solution

We also installed ClamAV in Step 3 so we need to set the path in Moodle

1st Create the Quarantine Directory

sudo mkdir /var/quarantine

Change Ownership

sudo chown -R www-data /var/quarantine

Navigate to Site Administration > Security > Anti-Virus

Check "Use ClamAV on uploaded files"

ClamAV Path : /usr/bin/clamscan

Quarantine Directory : /var/quarantine

Save Changes

Suggestions: Enable Zend OpCache/Change Document Root

Within the link above, https://docs.moodle.org/26/en/OPcache add the recommended settings to your 05-opcache.ini file.

sudo vi /etc/php5/apache2/conf.d/05-opcache.ini

Restart Apache for changes to take affect.

sudo service apache2 restart

That's it for the Zend OpCache!

You can also install a GUI to view the status of your Zend OpCache, not recommended on production servers.

cd /var/www/html/moodle/

Download the PHP Script to your Moodle directory, you should also add this file to /opt/moodle/.git/info/exclude file so it does not get removed when upgrading your installation.

sudo wget https://github.com/rlerdorf/opcache-status/blob/master/opcache.php

Visit http://ip.address.of.server/moodle/opcache.php

Don't like http://ip.address.of.server/moodle?

Open up Apache Config and change the document root

sudo vi /etc/apache2/sites-available/000-default.conf

On the line where DocumentRoot is;


Change From: DocumentRoot /var/www/html

Change To: DocumentRoot /var/www/html/moodle

:w
:q

Restart Apache for changes to take affect.

sudo service apache2 restart

Important note!

If you have already installed Moodle then you should make the below changes.

Edit config.php for Moodle

Under $CFG->wwwroot change to http://ip.address.of.server instead of http://ip.address.of.server/moodle
