Understanding DrupalWelcome to Drupal! Drupal is a powerful content management system which allows you to

create and maintain many different types of websites without needing to know any coding

languages.

INSTALLATION

http://drupal.org/node/1130898

To install Drupal on IIS version 7.0 by using Web PI 3.0, follow these

steps:

Prerequisites

Step 1. Install the Web Platform Installer 3.0

Step 2. Select the products and applications to install

Step 3. Review and configure the selected products and applications

Step 4. Verify the installation and configuration

Step 5. Enable clean URLs

STEP---1

Download Drupal1. At theproject download page, find the version you want to download. In this case, select

the first Drupal 7 version under the section 'Official Releases.' Click on 'Download.' Save the

file (don't open it with another program.)

2. Uncompress the file.Right-click on the .tar.gz file and select 7-Zip >> Extract here.Right-click on the .tar file and repeat. You will now see the final Drupal folder. Drag and

drop the folder where you need it to be.

Note: If you extract the files into a folder other than your web site's folder, copy thecontents of the Drupal folder into the appropriate web folder, rather than cutting/pasting

them. (This will ensure the files will inherit the appropriate permissions for the web server.)

Note:If you are using Apache instead of IIS skip the next two steps.

3. Create the files folder. In the sites/default folder, create a folder called files and grantmodify permissions for it to IIS_WPG (IIS6) or IIS_IUSRS (IIS7).

4. IIS7: Create/modify web.config file. Drupal distributions come with .htaccess filesfor *nix use; IIS7 users should convert this file to a web.config file for their site. If you have

used the IIS Manager to create a new site, a basic web.config file will exist in your site's

root directory. Edit the file to look like this example:
http://drupal.org/project/drupalhttp://drupal.org/project/drupalhttp://drupal.org/project/drupalhttp://drupal.org/project/drupal

5/30

Step 2: Create the database

Create a database and user using phpMyAdminThis presumes you have root access to phpMyAdmin

1. Log in to phpMyAdmin as the root user.2. Click Privileges andAdd a new User.3. In the User name field, enter the username you wish to use.4. In the Hostfield, select Localwhich is more secure, unless you will be accessing the

database with this user from another server.

5. Enter or generate a password for the user.6. In the Database for User list, select Create database with same name and grant all

privileges and click Go.

Create a database using PostgreSQL

The database must be created with UTF-8 (Unicode) encoding.

1. Create a database userThis step is only necessary if you don't already have a user setup (e.g. by your host) or you

want to create new user for use with Drupal only. The following command creates a new

user named 'username' (you should substitute this with the desired username), and

prompts for a password for that user:

createuser --pwprompt --encrypted --no-adduser

--no-createdb username

If everything works correctly, you'll see a CREATE USER notice.

2. Create the databaseThis step is only necessary if you don't already have a database setup (e.g. by your host) or

you want to create new database for use with Drupal only. The following command creates

a new database named "databasename" (you should substitute this with the desired

database name), which is owned by previously created "username":

createdb --encoding=UNICODE --owner=username databasename

If everything works correctly, you'll see a CREATE DATABASE notice.


6/30

Step 3: The settings.php fileYour Drupal download comes with a sample configuration file at sites/default

/default.settings.php. The default file must be copied and the new file must be given the

correct name, settings.php.

Please note: With Drupal 7.x, on some types of shared/local hosting, if PHP and Apache are

run by the same user, Drupal will attempt to execute the first three steps for you. If you get

errors referring to the "Settings file" during installation, you can perform these steps

manually.

1. Copy the default.settings.php to settings.php.Do this from the command line (working from the root of the directory containing your

Drupal installation) by typing

cp sites/default/default.settings.php sites/default/settings.php.

Please note: Do not simply rename the file. The Drupal installer needs both files.

2. You should now have a default.settings.php AND a settings.php file inyour sites/default directory.

3. Make the settings file writeable, so that the installer can edit it, typechmod a+w sites/default/settings.php or

chmod 666 sites/default/settings.php

Both commands have the same effect.

Several FTP tools likeFilezilla, Transmit, and Fetch allow you to change file permissions,

using a 'file attribute' or 'get info' command. In this case the file permission should be set to

666. If your FTP client has checkboxes for setting permissions, check both the Read and

Write boxes for "Owner", "Group", and "Others" (but leave the Execute boxes unchecked).

4. Please note: Do not forget to change permissions back after you have run the installationscript.Those permissions should be:chmod 640 settings.php

chmod 755 ../default

5. To let the files directory be created automatically, give the web server write privileges to thesites/default directory.

chmod a+w sites/default

Step 4: Run the installation script

Last updated June 9, 2012. Created byemmajaneon April 25, 2008.

Edited [email protected],Carolyn,arianek,Shai.Log in to edit this page.

For Drupal 7To run the Drupal install script, point your browser to the base URL of your web site.

The "base URL" means the document root (directory) where you placed your Drupal files

(and is defined in your web server configuration file). If you have installed Drupal on a web

host this will likely be a domain name such as http://www.example.com. If you installed

Drupal in a subfolder, then you should point your browser to the subfolder

(e.g. http://example.com/subfolder). If you have installed Drupal on your desktop machine

this URL might be http://localhost/drupal.

If the installation process does not simply appear by entering the base URL of your site, add

the file name "install.php" (for example http://www.example.com/install.php).

You will be guided through several screens:

1. Choose which profile to use for the installation (standard or minimal).Most people should select the "standard" option. The standard option comes with default

content types already enabled, such asArticle and Page, and with appropriate publishing

options already set. (Of course you can later edit these default content types and their

settings, or add additional ones.) The standard profile also has a useful collection of

modules pre-enabled for you.

The "minimal" option is targeted toward more experienced Drupal site creators who wish to

set up their own content types with associated publishing options. The minimal profile has

only three modules enabled:Block,Database logging, andUpdate status.

8/30

2. Select a languageIf you want to install using a language other than the default English, click the Learn how to

install Drupal in other languages link.


9/30

3. Verify requirementsIf your installation directory is not yet configured properly, you will be informed at this step.

You can correct the settings individually and either refresh the browser screen or click 'Try

again' to see whether there are any errors left.


10/30

Possible errors include:

Missing directories and/or incorrect permissionsThe installer will attempt to automatically set up a number of directories, but this may fail

due to permission settings. In this case you will find the missing directories listed.

sites/default/files sites/default/private sites/default/private/filesThese directories should be set to the following permissions chmod o+w

sites/default/files OR chmod 777 sites/default/files

Missing settings.php or incorrect permissionsIfsettings.php is missing or not accessible, follow the instructions inStep 3: Thesettings.php file. Note that you will need both the default.settings.php and settings.php

files.

4. Set up databaseEnter the database name as well as the username and password for the database that you

created inStep 2: Create the database. This username and password information allows

Drupal to access your database, so the install script can create tables. Note that this

is notthe username and password for administering Drupal; these will be created in the

next step.

TheAdvanced options will allow you to change the database host ('localhost' is usually used

in this entry: wamp/bin/apache/Apache2.2.11/bin/php.ini as an example of the location on a

Windows box runningWAMP). You can also change the port and the table prefix. You only

need to change the port if you are using a non-standard port number. The table prefix is

useful if you are installing multiple instances of Drupal tables that share the same database.

Click Save and continue at the bottom of the page.

5. Install profileA progress bar will appear and display notes from the installer regarding the progress of the

installation. If no errors are encountered, the next page will automatically load in your

browser.
http://www.wampserver.com/en/http://www.wampserver.com/en/http://www.wampserver.com/en/http://www.wampserver.com/en/


12/30

6. Configure siteInput the information for the first user account (which will be automatically assigned full

administration permissions) and provide basic web site settings.

In the Site name field enter the name you wish to use for the site. You can also edit it laterthrough the administration interface.

In the Site e-mail address field, enter the e-mail address that will be used by Drupal when itsends out notifications such as registration information.

In the Site maintenance accountfield, enter the Username, E-mail address,andpasswordfor the main administration account.Note that there is a distinction, as of Drupal 7, between the main administration account

that you set up on this page, and the "Administrator" site administratoruser role that you

will see when you visit the "Roles" and "Permissions" pages in the administration interface.

The account you set up in the Site maintenance accountsection during installation is a

super-user who has overall control over every aspect of the management and configuration

of the site. (This will be http://www.example.com/user/1, for those of you familiar with that


13/30

account from earlier versions of Drupal.)

In the Server settings field, select your Default countryand Default time zone. In the Update notifications field leave both boxes checked if you want your Drupal server to

alert you when updates are required. Often updates relate to security issues and are

important to perform. However, if you have restricted Internet connectivity (for example if

you are behind a corporate firewall) you may want to leave these settings unchecked and


14/30

test them later.


15/30

Click "Save and continue". On success you will see the Drupal installation completescreen. If

there are any error messages, review and correct them now.

Secure your site

After the installation is complete, you will want to change the permissions on the

settings.php file back so that it is protected:

chmod u=rw,o=r,a=r sites/default/settings.php OR chmod 644 sites/default/settings.php

If you make manual changes to the settings.php file later, be sure to protect it again after

making your modifications.

Failure to remove write permissions to that file is a security risk. (Although the default

location for the settings.php file is at sites/default/settings.php, it may be in another

location if you use the multi-site setup.)

For Drupal 6To run the install script point your browser to the base URL of your website.

The base URL is defined in your Web server configuration file and is specific to the

document root where you placed your Drupal files. If you have installed Drupal on a Web


16/30

server this will likely be a domain name such ashttp://example.com. If you have installed

Drupal on your desktop machine this URL might behttp://localhost.

You will be guided through several screens to set up the database, create tables,

add the first user account and provide basic web site settings.
http://example.com/http://example.com/http://example.com/http://localhost/http://localhost/http://localhost/http://localhost/http://example.com/

Built-in Installation Profiles (Drupal 7)

Last updated March 10, 2012. Created byCarolynon April 14, 2011.

Edited byscreenack.Log in to edit this page.

The Standard profile has several core modules enabled. It has more default configuration

set up, including several default admin tools. This profile does more to show what core cando, and can save site building time by having defaults for common use cases.

The Minimal profile has only a few very basic modules installed. This profile is useful if you

only want very specific features, or if it will take more work to undo the defaults provided

with the Standard profile.

Details

This table shows what extra modules will get enabled with the Standard profile:

Step 5: Set up cron

http://drupal.org/cron

Configuring cron is an extremely important task in your Drupal website setup. Searchmodule's indexing of your website's content, Aggregator module's retrieval of feeds, Ping

module's notification of other sites of updates, and System module's routine maintenance

tasks, such as pruning of logs, all depend on a properly configured cron job.

What is a cron job?

Many Drupal modules have tasks that have to take place from time to time. Think of cron as

the tolling of a bell, letting Drupal know that it should perform the appropriate tasks.

The actual "cron job" is a time-triggered action that is usually (and most efficiently)

performed by your website's hosting server, but can also be configured by a remote service

or even from your own desktop.

For your Drupal site, what actually happens is that the cron job triggers an invisible visit to

the site's cron.php file (http://www.example.com/cron.php) which, in turn, executes tasks

on behalf of installed modules. [Note: In Drupal 7, the direct path to cron is obscured by a

key (to prevent unauthorized bots from hammering your cron). The exact path to your site's

cron file

e.g.,http://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v1

1... is displayed in your site's Status Report.]

Triggering Drupal cron without a cron job

With the inclusion of "Poor man's cron" in the Drupal 7 core, it is no longer necessary to set

up a cron job on your web server. Instead, you can configure the frequency with which cron

is run on admin/config/system/cron (Administration > Configuration > System > Cron).

Cron will then be triggered by end users visiting your site. (You can also disable this

functionality entirely for performance here, by setting the "Run cron every" value to "Never"

or setting $conf['cron_safe_threshold'] = 0 in settings.php.)

Poormanscron

Step 6: Clean URLs

Enabling Clean URLs in DrupalNote: The standard Drupal installation contains a sample .htaccess file which supports clean

URLs. It is easy to miss copying this file, because of the leading "dot". So before trying to

enable Clean URLs, make sure this file exists in your Drupal installation.
http://www.example.com/cron.phphttp://www.example.com/cron.phphttp://www.example.com/cron.phphttp://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v11i-vNeSfhttp://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v11i-vNeSfhttp://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v11i-vNeSfhttp://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v11i-vNeSfhttp://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v11i-vNeSfhttp://example.com/cron.php?cron_key=hW309d0DD2Qw4_4NXXnUW7q3SFCQfPP8v11i-vNeSfhttp://www.example.com/cron.php


23/30

Drupal 7.x

In Drupal 7, the installer tests for compatibility with Clean URLs as a part of the installation

process. If the environment is tested as compatible with Clean URLs, it will be enabled as

part of the installation process and no further action is required to enable Clean URLs.

If you need to enable Clean URLs post installation, Drupal will run the clean URL test

automatically when you navigate to the Clean URLs configuration page (Administer >Configuration > Search and metadata), show the results, and allow you to save

configuration.

You can enable or disable it at a later time by following these steps:

1. Navigate to the Clean URLs configuration page (Administer > Configuration > Searchand metadata)

2. Wait for the automated Clean URLs test to run.3. Check or uncheck the Enable clean URLs checkbox4. Click "Save configuration"

Even if Clean URLs are successfully enabled at install-time, if you have a dedicated server

you may still want to follow the steps (below) to enable the more efficient httpd.conf rewrite

method for clean URLs. If you choose to do that, you might want to turn off Clean URLs

while you are working on the server.

STEP-8

After Installation

Installing modules and themes

Last updated April 24, 2011. Created bysepeckon September 16, 2007.

Edited byogi,arianek,silverwing,bethhauck.Log in to edit this page.

Now that you've installed Drupal, you will want to customize it to your tastes by adding

modules and themes. The basics of managing modules and themes are fairly similar. If you

browse to the sites/all folder you will find a README.txt file.

This directory should be used to place downloaded and custom modules and themes which

are common to all sites. This will allow you to more easily update Drupal core files. These

modules and themes should be placed in subdirectories called modules and themes as

follows:

sites/all/modules sites/all/themes

You can find a synopsis of any contributed module or theme by visiting its project page, but

many modules and themes also include README.txt file with more detailed information.
http://drupal.org/user/5195http://drupal.org/user/5195http://drupal.org/user/5195http://drupal.org/user/71467http://drupal.org/user/71467http://drupal.org/user/71467http://drupal.org/user/158886http://drupal.org/user/158886http://drupal.org/user/158886http://drupal.org/user/13009http://drupal.org/user/13009http://drupal.org/user/13009http://drupal.org/user/412953http://drupal.org/user/412953http://drupal.org/user/412953http://drupal.org/user?destination=node%2F176043http://drupal.org/user?destination=node%2F176043http://drupal.org/user?destination=node%2F176043http://drupal.org/user?destination=node%2F176043http://drupal.org/user/412953http://drupal.org/user/13009http://drupal.org/user/158886http://drupal.org/user/71467http://drupal.org/user/5195


24/30

To view a module's README.txt file without having to download anything,

visit http://drupalcode.org/project/modulename.git/blob/HEAD:/README.txt. Be sure to first

replace the word modulename with the name of the particular module.

For themes, visit http://drupalcode.org/project/themename.git/blob/HEAD:/README.txt.

Option 1: Upload the module through the Drupal interface

Navigate to the install page. Navigate to Modules > List (tab),or http://example.com/admin/modules, and click the link 'Install new module.' (You must

have theUpdate managermodule enabled to see this link.) Follow the prompts. You will be prompted to provide either the URL to the download, or

to upload the .tar.gz or .zip file from your local computer. Click 'Install', and the Update

manager will copy the files into your sites/all/modules folder. (SeeUpdate managerfor

more information about what that core module can do.) The next screen gives you two

links. Click 'Enable newly added modules' and skip down to the 'Enable and configure'

section.

If your site asks for your FTP username and password, it is referring to the

username and password to access yoursite, not drupal.org

A note about FTP: If FTP is not enabled for your server, you may receive an error message.

Drupal will not be able to diagnose the problem, only tell you that there is one. It's up to

you to determine whether your server is properly configured for FTP.

Option 2: Upload the module manually

Extract the files.The downloaded module package will be in a compressed file format suchas 'tar.gz'. On Windows, use a program like7-zipto extract the files. On modern Mac

systems, double-click the .tar.gz file. For *nix systems, use the command line:
http://drupal.org/documentation/modules/updatehttp://drupal.org/documentation/modules/updatehttp://drupal.org/documentation/modules/updatehttp://drupal.org/documentation/modules/updatehttp://drupal.org/documentation/modules/updatehttp://www.7-zip.org/http://www.7-zip.org/http://www.7-zip.org/http://www.7-zip.org/http://drupal.org/documentation/modules/updatehttp://drupal.org/documentation/modules/update


25/30

tar -zxvf modulename-drupalversionnumber.tar.gz

You should see a list of files extracted into a folder.

Upload the folder. Transfer your files with SFTP orFTP to the desired modules folder in your Drupal installation (or if you are using version

control, add and commit them to your code repository). The modules folder at the top level

of your Drupal installation is reserved for Drupal core modules (the ones that come with the

original download of Drupal). Contributed modules belong in sites/all/modules. If you are

running amulti-site installationof Drupal, use sites/my.site.folder/modulesfor modules

there that are specific to a particular site in your installation. Modules that will be shared

between all sites should be placed in sites/all/modules.

Please note: Especially for sites with a lot of additional modules, many people have begun

to further divide the modules folder, to help stay organized. A typical way of doing thiswould be:

sites/all/modules/contrib for all contributed modules. sites/all/modules/custom for all custom modules. sites/all/modules/features if you have additional modules that were created

usingFeatures.

Enable and configure

Read the directions. If the module has an installation file (usually INSTALL.txt and/orREADME.txt), read it for specific instructions. There are modules that require special

treatment, and even modules that depend on other downloaded files to function properly.

Sometimes the README file has no .txt extension. If you double-click it, your computerwon't know what program to use. In that case, open a text editor first, and then open the

file using the editor's 'file open' command.

Enable the module. Navigate toAdminister >Modules or http://example.com/admin/modules. Check the 'Enabled' box next to the module

and then click the 'Save Configuration' button at the bottom. Note: If you are updating an

existing module, you'll need to click 'update script' at the top of the page or

loadhttp://www.example.com/update.php, then click 'Continue' (after making a backup of

both your database and 'sites' folder).

Set up permissions. Some modules will require that you change permissions to get themworking. Permissions information may be in the instructions that came with the module.

Navigate toAdminister > Modules and click on the 'Permissions' button for the desired

module. You can also do this on the

Permissions page (Administer > People > Permissions). Scroll down to see if the module

appears in the list and, if it does, give the appropriate permissions to desired roles.

Adjust settings. Most modules will have some type of settings page. It will vary frommodule to module but if not described in the README.txt file, it can usually be located by

navigating to (Administer > Modules) and clicking on the 'Configure' link for that module.

Not all modules have settings pages.Please note: You can only have one copy of a module with the same name in each Drupal

site. The module's name is determined by the name of the .module file, not by the name of

the directory.

Tip: If you run into problems, search the module's issue queue and theforums. If your

problem hasn't already been addressed, post a question or issue and someone will try to

help you out.

Tip: To keep up-to-date on any issues and fixes related to your newly installed module(s),

you cancreate a user accounton Drupal.org (if you haven't done so all ready) and then

subscribe to the feed of each module you are using.

Installing themes

Last updated June 20, 2012. Created bysepeckon September 16, 2007.Edited byGreenSkunk,aspilicious,WorldFallz,heather.Log in to edit this page.

1. Download the theme.You can find themes onhttp://drupal.org/project/themes, as well as some external sites.

Make sure the version of the theme matches your version of Drupal. Note that themes

labeled "DEV" are in a development stage. They may be written for a

previous/current/future version of Drupal, and they are considered unstable and should be

handled with care.

2. Extract the files.When you first get the theme, it will appear in a compressed file format such as 'tar.gz'.

On Windows, use a program like 7-Zip to extract it. On the Mac, you can use Stuffit

Expander. To extract the file using the Unix command line:tar -zxvf themename-drupalversionnumber.tar.gz

You should see a list of files extracted into a folder.

3. Upload the folder.FTP/Copy/SCP your files to the desired themes folder in your Drupal installation. Since

the themes folder at the top level of Drupal is typically reserved for Drupal core themes,

you should create a sites/all/themes/ directory for contributed(non-core) themes and

put uploaded themes there. If you are running amulti-site installationof Drupal, you can

create a themes folder under sites/my.site.folder and put themes there that are specific to

a particular site in your installation. Themes that will be shared between all sites should be

placed in sites/all/themes.

4. Read the directions.If the theme has an installation file (usually INSTALL.txt and/or README.txt), read it for

specific instructions. There are themes that require special treatment to function properly.5. Enable the theme.

Go to administer > site building > themes. Check the 'Enabled' box next to the theme.

6. Optional: Make it the active, default theme.Check the 'default' box to make this the chosen theme for your site. Enabled alone will

allow users to select the theme, if you have allowed that permission.

7. Click the 'Save Configuration' button at the bottom.If you run into problems, check the themes issue queue and search the forums. If your

problem hasn't already been addressed, post a question and someone will try to help you

out.

Theme settingsDrupal 7You can locate these settings at "Administer > Appearance > Settings > themeName". For

example, the site's slogan can be suppressed by unchecking the "Site slogan" check box on

that page.

These checkboxes show themselves depending on the features enabled inside the.info file.

It must be specified with the key of 'features' followed by empty brackets then the feature

itself, e.g., features[] = the_feature. If none are defined, the following values are

assumed.

features[] = logo

features[] = name

features[] = slogan

features[] = node_user_picture

features[] = comment_user_picture

features[] = comment_user_verification

28/30

features[] = favicon

features[] = main_menu

features[] = secondary_menu

Drupal 7 removes the previously available mission and search as theme features (they can

be created and controlled as blocks instead) and adds a toggle for "User verification status

in comments".

To disable any features, only add the ones you want into the .info file. Defining only the

features needed for the theme will omit the rest. Some of the features will also enable

related form fields. For example, 'logo' will enable an upload field for the image along with

the checkbox.

A few notes:

The contents of the .info file are cached in the database so altering it will not be noticed byDrupal. (Do not confuse this with thetheme registry.) To learn how to clear it, check out the

options inClearing the theme cache.

hook_features() is no longer supported.

IIS (Windows)

On a Windows system using IIS:

1. Right-click on sites\default\settings.php and grant Write permissions toIUSR_MachineName (IIS6) or IUSR (IIS7).

Server 2008: You can also do this from the command line from within your sites\defaultdirectory:

icacls settings.php /grant IUSR:W

The installer will change the file back to Read Only after installation, but you should verify

this after installation.

What is PDO?

Last updated August 10, 2012. Created bybekasuon August 14, 2009.

Edited byklauq,authentictech,Carolyn,Damien Tournoud.Log in to edit this page.

PDO is an acronym for PHP Data Objects. PDO is a lean, consistent way to access

databases. This means developers can write portable code much easier. PDO is not an

abstraction layer like PearDB. PDO is a more like a data access layer which uses a unified

API (Application Programming Interface).

How to enable PDO

To enable PDO, configure --enable-pdo and --with-pdo-sqlite --with-pdo-mysql or whatever

database needs supporting by PDO (see thePHP manualfor more information).

Windows users

For Apache, you will need to make sure php_pdo.dll and php_pdo_mysql.dll exist in thephp/ext directory, un-comment or add the appropriate lines in php.ini, and restart the web

server.

For IIS, PDO DLLs are not enabled by default. The preferred method for enabling them isto go to the Control Panel | Add/Remove Programs, highlight your PHP installation and click

"Change" (Change/Remove - XP). Specify "FastCGI", then modify the installed extensions to

include these two, then restart your server.
