Installing Moodle on 5.0-Nano

Introduction

This step-by-step guide shows how to install Moodle on Uniform Server V5.0-Nano. In addition shows how to resolve fixed paths allowing Moodle to be run from a USB memory stick.

Windows does not support true cron jobs however V5.0-Nano has an integrated portable Cron catering for both hard drive and USB memory stick installations.

Pre-Installation

Install Uniform server

  1. A) Create a new folder named moodle_b (Can be any name)
  2. Extract a new copy of Uniform Server V5.0-Nano to this folder
    (Double click on file to extract).

Download Moodle

  1. B) Create a new folder moodle_a (Can be any name its only a temporary folder)
  2. Download the latest version (moodle-weekly-19.zip) of Moodle from Moodle download page
  3. Copy the file dowloaded (moodle-weekly-19.zip) to moodle_a
  4. Unzip moodle-weekly-19.zip into this folder.
    (Right click on file, select extract all, extract to current path.)

Copy files to Uniform Server

  1. C) Expand the folder moodle-weekly-19
  2. D) Copy folder moodle to Uniform Servers's root folder www

Switch to production, start servers

UniServer’s default is to use the production PHP configuration file however you may have switched configuration files during development.

Before installing any applications ensure the production configuration is selected.

Check configuration file:

  1. Start UniTray, in folder UniServer double click on Start.exe tray icon created.
  2. Check configuration: Left click tray icon > Server Status – Top of page php.ini displays either Production or development.
  3. If Production displayed no action required you can start servers.
  4. If development displayed proceed as follows:
  5. Switch to production, Left click tray icon > Advanced > click php.ini switch to Production.

Start Servers:

  • Start Uniform Server. Left click tray icon > click Start UniServer

Create a Moodle Database

Creating the Moodle database is straight forward, tables are automatically inserted during installation

  1. Left click tray icon > click phpMyAdmin - This opens phpMyAdmin in your browser
  2. A) We want to create a new database. Name it moodle (or something easy to remember if you change name make sure you use this name during installation.)
  3. B) Click on Create to create the database

File:Moodle 2.gif

Note:

  • You can start phpMyAdmin from Apanel, start Apanel by typing http://localhost/apanel/ into your browser address bar.
  • From Apanel click on the phpMyAdmin link. (left menu under tools)

Portability - USB Memory Stick

To run Moodle from a Memory stick, copy the folder UniServer and all its content to whatever drive your memory stick is on.

Note: This process is not fast; writing 104 MB (UniServer plus Moodle) took just over 20 minutes. In the same vain do not expect exceptional performance, Moodle uses a large database hence is slow when run from a memory stick. That said I found it just about acceptable.

Hard Coded path

During installation Moodle uses absolute paths (drive letter and folder path to moodle) and hard wires these into a configuration file. This means you cannot move the installation to another location and expect Moodle to run. A solution to this problem requires modifying Moodle's configuration file config.php.

Open the following file in a text editor:

UniServer\www\moodle\config.php

Its a small file locate the following three lines (yours may be slightly different):

$CFG->wwwroot   = 'http://localhost/moodle';
$CFG->dirroot   = 'C:\moodle_b\UniServer\www\moodle';
$CFG->dataroot  = 'C:\moodle_b\UniServer/moodledata';

The hard coded paths start with C: followed by a list of folders to the Moodle installation these hard coded paths prevent portability. Another problem, first line assumes you are running servers on localhost and standard port 80 this becomes an issue if you run move servers (multi-server operation) because it changes all ports.

Solution is to let PHP automatically calculate absolute paths and web-root folder.

Replace the above three lines with the following code:

$splitArray   = explode("\\www",__DIR__);  // Split at folder www to
$base         = "$splitArray[0]";          // find drive letter and sub-folders 

$root   = 'http://'.getenv("HTTP_HOST").'/moodle';         // Local testing
//$root = 'http://'.GetHostByName($REMOTE_ADDR).'/moodle'; // moving from event to event

$CFG->wwwroot   = $root;
$CFG->dirroot   = $base.'\www\moodle';
$CFG->dataroot  = $base.'\moodledata';
?>

The above change makes Moodle completely portable.

Tip UniServer on a laptop

I lifted the following tip from gdunc blog, it looks very useful, hence I integrated this into the above:

For those users who use UniServer on a laptop and move from event to event. To allow external users to view your moodle make the following changes:

Change:

$root   = 'http://'.getenv("HTTP_HOST").'/moodle';         // Local testing
//$root = 'http://'.GetHostByName($REMOTE_ADDR).'/moodle'; // moving from event to event

To:

//$root   = 'http://'.getenv("HTTP_HOST").'/moodle';         // Local testing
$root = 'http://'.GetHostByName($REMOTE_ADDR).'/moodle'; // moving from event to event

This switches from localhost to your domain.

In addition to allow external access you need to put your servers on-line as follows:

Edit file: UniServer\www\.htaccess

Change these lines:

Order Deny,Allow
Deny from all
Allow from 127.0.0.1

To:

#Order Deny,Allow
#Deny from all
#Allow from 127.0.0.1

Move Servers

One of Uniform Server’s unique features is the capability to run more than one complete server on the same PC. When running a server from a USB memory stick you can use this to great advantage and prevent server clashes. You will have noticed UniTray’s icon displays one (meaning standard ports). Moving UniServer increments this digit and so on for each server move. In reality it’s not just a port change but a complete server update, running server status displays the server characteristics.

Move Servers:

  1. Assumes a new extracted server (see note 1)
  2. Stop all running Uniform Servers
  3. Start UniTray, in folder UniServer double click on Start.exe tray icon created.
  4. Move servers, Left click tray icon > Advanced > click Move Servers multi-server operation.
  5. In the pop-up window at all prompts press enter to accept defaults.
  6. The tray icon will display 2, if you already use a server with this number repeat steps 4 and 5 each server must have a unique number.


  • After moving the servers you can now install Moodle as explained above.
  • However before proceeding you need to use the new server ports for installation.
  • To find these: Left click tray icon > Server Status


I moved the servers to icon 3 hence Apache port = 82 and MySQL port = 3308

To start Moodle installation: type http://localhost:82/moodle/install.php into your browser

Database Configuration step 4) Host Server: name becomes: localhost:3308

After installation page access requires the addition of a port number as shown

  • Site address: http://localhost:82/moodle/

Note 1:

If you have already installed Moodle on UniServer V5-Nano and want to move the servers it is possible.

  1. Follow steps 2-6 as above
  2. Edit file UniServer\www\moodle\config.php
  3. Assumes you have made the changes as explained in Hard Coded path
  4. Now locate line (6)
    Change line: $CFG->dbhost = 'localhost';
    To: $CFG->dbhost = 'localhost:3308';
  5. Save file.

Use the port number that matches your server, start the servers. Pages are accessible as mentioned above just remember to use the port number that matches your server.

Cron

Moodle has a cron.php script that needs to be periodically run. It takes care of various routine tasks for example unsubscribing inactive members and sending out email messages.

Top

Manualy Run Cron

To keep Moodle happy you need to periodically run the cron.php script.

For a personal implementation of Moodle you can run cron.php occasionally by typing the following into your browser address bar:

http://localhost/moodle/admin/cron.php

Automatically Run Cron

Manually running Cron can become tedious an alternative solution is to use UniServer 5.0-Nano's built in portable-cron.

Top

Enable portable Cron

Edit file: UniServer\unicon\main\run_cron.php

Uncomment this line as shown:

$dummy = file("http://localhost/moodle/admin/cron.php"); // Uncomment to enable 

Change the timer to suit application

sleep(15);  // Set required delay (seconds)

Top

Run portable Cron

Manually run cron from UniTray

  • Start: Left click tray icon > Advanced > click Start Portable Cron
  • Stop: Left click tray icon > Advanced > click Stop Portable Cron

Top

Automatically start and stop with servers

Edit file: UniServer\unicon\tray_menu\UniTray1.ini

Locate these lines under [Menu.Left] Menu section (for convenience lines have been split):

Type: item; Caption: "Start UniServer (Apache MySQL)";
 Action: shellexecute; FileName: "%PHP%\php.exe";
 Parameters: " -n %ServerConMain%\start_servers.php 7";ShowCmd: hidden; Glyph: 9

Type: item; Caption: "Stop  UniServer (Apache MySQL)";
 Action: shellexecute; FileName: "%PHP%\php.exe";
 Parameters: " -n %ServerConMain%\stop_servers.php 7";ShowCmd: hidden; Glyph: 11

  • Replace start_servers.php 7 with start_servers.php 23
  • Replace stop_servers.php 7 with start_servers.php 23

Note: Values are binary coded

 Note: Binary 1+2+4+16 = 23  
 1  - Run Apache server 
 2  - Run MySQL  server
 4  - Start Index page
 16 - Run cron

Summary

Although there are a large number of steps Moodle is easy to install on Uniform Server.

Real reason for installing Moodle was to test its compatibility with PHP 5.3.0 and UniServer 5.0-Nano. It takes a lot to impress me; Moodle’s installation ran flawlessly very impressive and a credit to there design team.
