This guide explains how to install Moodle for the first time. There are links to other pages that go into more detail and try to cover the majority of possible web server setups.
However, you may want to consider reviewing Finding and Selecting A Web Host to consider whether you really want to install Moodle yourself. If you decide to move forward with an installation, please read all the installation documentation carefully. If you still have a problem for which you can't find the answer, please see the Using Moodle Installation problems forum where there are many people who can help you.

Moodle is primarily developed in Linux using Apache, MySQL and PHP (also sometimes known as the LAMP platform). It is also regularly tested with Windows XP/2000/2003 (WAMP), Solaris 10 (Sparc and x64), Mac OS X and Netware 6 operating systems. Support for PostgreSQL, Oracle and Microsoft SQL Server is also available.
The requirements for Moodle are as follows:
- Disk space: 160MB free (min). You will require more free space to store your teaching materials.
- Memory: 256MB (min), 1GB (recommended). The general rule of thumb is that Moodle can support 50 concurrent users for every 1GB of RAM, but this will vary depending on your specific hardware and software combination.
- This includes hosting limits of PHP or MySQL on a hosting service.
- The capacity can limit the number of users your Moodle site can handle. See User site capacities
- Web server software. Most sites use Apache as the web server software. Moodle should work fine under any web server that supports PHP, such as IIS on Windows platforms.
- PHP scripting language. (Please note that there have been issues installing Moodle with PHP-Accelerator). There are currently two versions (or branches) of PHP available: PHP4 and PHP5. See the PHP Moodle version requirements here PHP settings by Moodle version.
If you want to run Moodle on your own computer, please see Installing Apache, MySQL and PHP for step-by-step instructions for installation on most popular platforms.
Download and copy files into place
After downloading and unpacking the archive, or checking out the files via CVS, you will be left with a directory called "moodle", containing a number of files and folders.
For the standard package, you can either place the whole folder in your web server documents directory, in which case the site will be located at http://yourwebserver.com/moodle, or you can copy all the contents straight into the main web server documents directory, in which case the site will be simply http://yourwebserver.com.
- Tip: If you are downloading Moodle to your local computer and then uploading it to your web site, it is usually better to upload the whole archive as one file, and then do the unpacking on the server. Even web hosting interfaces like cPanel allow you to uncompress archives in the "File Manager".
If you're interested, Moodle site moodle directory gives a quick summary of the contents of the Moodle folder, to help get you oriented.
Setting-up your web server
You need to create a blank database for Moodle to use and finally create a directory on your hard disk for Moodle to save your materials and other files you upload into your courses.
Sometimes you have to check beforehand that the web server settings are correct to ensure that Moodle will install successfully.
Create empty database
You need to create an empty database (eg "moodle") in your database system along with a special user (for example "moodleuser") that has access to that database (and that database only). You could use the "root" user if you wanted to for a test server, but this is not recommended for a production system: if hackers manage to discover the password then your whole database system would be at risk, rather than just one database.
For more help with this see Create Moodle site database.
If you are using a webhost, they will probably have a control panel web interface for you to create your database.
The cPanel system is one of the most popular of these. To create a database using cPanel:
- Click on the MySQL Databases icon.
- Type moodle in the New Database field and click Create Database.
- Type a username and password (not one you use elsewhere) in the respective fields and click Create User.
Note that the username and database names may be prefixed by your cPanel account name and an underscore, and truncated to 16 characters. When entering this information into the Moodle installer - use the full names.
- Now use the Add Users to Databases button and give this new user account ALL rights to the new database.

Creating the data directory
Moodle will also need some space on your server's hard disk to store uploaded files, such as course documents and user pictures. The Moodle installer tries hard to create the moodledata directory for you but if it fails then you will have to create a directory for this purpose manually.
Security warning: For security purposes, it is CRITICAL that this directory is NOT accessible directly via the web. The easiest way to do this is to simply locate it OUTSIDE the web site root directory (it is the folder that the main part of your URL -that is, the part up to the first single / - points to; for example, in http://your.domain.com/moodle/admin/cron.php, it is http://your.domain.com/).
If you don't protect the data directory from direct web access, anybody will be able to impersonate any user of your Moodle site (including the admin user!!!), and all of your course materials will be available to the web at large.
See Creating Moodle site data directory for more information about security in creating a data directory in
- CPanel in webhosts
- Moodle's config.php file
This and the following sections are only necessary if you run into problems with the default installation procedure described above.
- Firstly, make sure that your web server is set up to use index.php as a default page (perhaps in addition to index.html, default.htm and so on). In Apache, this is done using a DirectoryIndex parameter in your httpd.conf file. Mine usually looks like this:
DirectoryIndex index.php index.html index.htm
- Just make sure index.php is in the list (and preferably towards the start of the list, for efficiency).
- Secondly, if you are using Apache 2, then you should turn on the AcceptPathInfo variable, which allows scripts to be passed arguments like http://server/file.php/arg1/arg2. This is essential to allow relative links between your resources, and also provides a performance boost for people using your Moodle web site. You can turn this on by adding these lines to your httpd.conf file. (NB: This setting, or any equivalent, is not required in Apache 1)
Creating custom php.ini files
Moodle requires a number of PHP settings to be active for it to work. The first level of instructions are located in the php.ini file.
- See Installing Moodle/Creating custom php.ini files for details.
- See PHP settings by Moodle version for more information on different settings by Moodle version.
Alternative to php.ini and httpd.conf files
If you do not have access to your php.ini or httpd.conf files on you web host, see Create .htaccess file.
Start Moodle install
There are two basic ways to install Moodle: Most Moodlers are used to the installer script but with Moodle 2.0 you may install it from the command line.
Install with installer script
To run the installer script (install.php), just try to access your Moodle main URL using a web browser, or access http://yourserver/install.php directly.
(The Installer will try to set a session cookie. If you get a popup warning in your browser make sure you accept that cookie!)
Moodle will detect that configuration is necessary and will lead you through some screens to help you create a new configuration file called config.php. At the end of the process Moodle will try and write the file into the right location, otherwise you can press a button to download it from the installer and then upload config.php into the main Moodle directory on the server.
Along the way the installer will test your server environment and give you suggestions about how to fix any problems. For most common issues these suggestions should be sufficient, but if you get stuck, check in the Installation Forum for more help.
Go to the admin page to continue configuration
Once the basic config.php has been correctly created in the previous step, trying to access the front page of your site will take you to the "admin" page for the rest of the configuration.
The first time you access this admin page, you will be presented with a GPL "shrink wrap" agreement with which you must agree before you can continue with the setup.
Now Moodle will start setting up your database and creating tables to store data. Firstly, the main database tables are created. You should see a number of SQL statements followed by status messages. You should see SUCCESS next to each one until you see "Main databases set up successfully."
- Tip: If you don't see these, then there must have been some problem with the database or the configuration settings you defined in config.php. Please see Install Moodle with installer script for more details and issues.
Scroll down the very bottom of the page and press the "Continue" link.
You should now see a form where you can define more configuration variables for your installation, such as the default language, SMTP hosts and so on. Don't worry too much about getting everything right just now - you can always come back and edit these later on using the admin interface. The defaults are designed to be useful and secure for most sites. Scroll down to the bottom and click "Save changes".
Next you will see more pages that print lots of status messages as they set up all the tables required by the various Moodle module. As before, they should all be green.
Scroll down the very bottom of the page and press the "Continue" link.
The next page is a form where you can define parameters for your Moodle site and the front page, such as the name, format, description and so on. Fill this out (you can always come back and change these later) and then press "Save changes".
Finally, you will then be asked to create a top-level administration user for future access to the admin pages. Fill out the details with your own name, email etc and then click "Save changes". Not all the fields are required, but if you miss any important fields you'll be re-prompted for them.
Make sure you remember the username and password you chose for the administration user account, as they will be necessary to access the administration page in future.
(If for any reason your install is interrupted, or there is a system error of some kind that prevents you from logging in using the admin account, you can usually log in using the default username of "admin", with password "admin".)
Once successful, you will be sent to the home page of your new site! Please note the Site administration block on the left with links. These items are only visible to you because you are logged in as the admin user. All your further administration of Moodle can now be done using this block.
Installing Moodle using command line
Installing Moodle using command line is just as easy as installing Moodle using the web browser. Change your current directory to the moodle root directory the admin directory for example:
More information about the options can be found using
$php cliupgrad.php --help
When you choose non interactive mode without any options all the default values are assumed.
Set up cron
Moodle's background tasks (e.g. sending out forum emails and performing course backups) are performed by a script which you can set to execute at specific times of the day. This is known as a cron script. Please refer to the Cron instructions.
Set up backups
Please refer to the backup instructions.
Create a new course
Congratulations on setting up your Moodle site! You can now create a new course and have a play ;-)
