Configuration file
From MoodleDocs
The name for Moodle's configuration file is config.php. The file is located in the moodle directory. It is not included in the Moodle download packages and is created by the installation process from the template file config-dist.php (which is included in Moodle packages).
Sample config.php file
Although the installation process creates the config.php file for you, there may be times when you want to do this yourself. Here is a sample config.php file to work from.
WARNING: You may want to edit the config.php file directly if, for example, you change you database password or change servers completely. If you do so, be very careful that there are no spaces or line breaks after the final "?>" in the file. If there are such spaces, you may get blank pages.

The config-dist.php file
The config-dist.php file is the template file. It contains the usual settings of a config.php file, with some additional settings that don't have a UI for them. To use these settings you have to add them to the configuration file.
Here is the contents of the config-dist.php:

//=========================================================================
// 1. DATABASE SETUP
//=========================================================================
// First, you need to configure the database where all Moodle data //
// will be stored. This database must already have been created //
// and a username/password created to access it. //
// //
// mysql - the prefix is optional, but useful when installing //
// into databases that already contain tables. //
//
// postgres7 - the prefix is REQUIRED, regardless of whether the //
// database already contains tables. //
// //
// A special case exists when using PostgreSQL databases via sockets. //
// Define dbhost as follows, leaving dbname, dbuser, dbpass BLANK!: //
// $CFG->dbhost = " user='muser' password='mpass' dbname='mdata'"; //
//
$CFG->dbtype = 'mysql'; // mysql or postgres7 (for now)
$CFG->dbhost = 'localhost'; // eg localhost or db.isp.com
$CFG->dbname = 'moodle'; // database name, eg moodle
$CFG->dbuser = 'username'; // your database username
$CFG->dbpass = 'password'; // your database password
$CFG->prefix = 'mdl_'; // Prefix to use for all table names
$CFG->dbpersist = false; // Should database connections be reused?
// "false" is the most stable setting
// "true" can improve performance sometimes
//=========================================================================
// 2. WEB SITE LOCATION
//=========================================================================
// Now you need to tell Moodle where it is located. Specify the full
// web address to where moodle has been installed. If your web site
// is accessible via multiple URLs then choose the most natural one
// that your students would use. Do not include a trailing slash
$CFG->wwwroot = 'http://example.com/moodle';
//=========================================================================
// 3. SERVER FILES LOCATION
//=========================================================================
// Next, specify the full OS directory path to this same location
// Make sure the upper/lower case is correct. Some examples:
//
// $CFG->dirroot = 'c:\program files\easyphp\www\moodle'; // Windows
// $CFG->dirroot = '/var/www/html/moodle'; // Redhat Linux
// $CFG->dirroot = '/home/example/public_html/moodle'; // Cpanel host
$CFG->dirroot = '/home/example/public_html/moodle';
//=========================================================================
// 4. DATA FILES LOCATION
//=========================================================================
// Now you need a place where Moodle can save uploaded files. This
// directory should be readable AND WRITEABLE by the web server user
// (usually 'nobody' or 'apache'), but it should not be accessible
// directly via the web.
//
// - On hosting systems you might need to make sure that your "group" has
// no permissions at all, but that "others" have full permissions.
//
// - On Windows systems you might specify something like 'c:\moodledata'
$CFG->dataroot = '/home/example/moodledata';
//=========================================================================
// 5. DATA FILES PERMISSIONS
//=========================================================================
// The following parameter sets the permissions of new directories
// created by Moodle within the data directory. The format is in
// octal format (as used by the Unix utility chmod, for example).
// The default is usually OK, but you may want to change it to 0750
// if you are concerned about world-access to the files (you will need
// to make sure the web server process (eg Apache) can access the files.
// NOTE: the prefixed 0 is important, and don't use quotes.
$CFG->directorypermissions = 02777;
//=========================================================================
// 6. DIRECTORY LOCATION (most people can just ignore this setting)
//=========================================================================
// A very few webhosts use /admin as a special URL for you to access a
// control panel or something. Unfortunately this conflicts with the
// standard location for the Moodle admin pages. You can fix this by
// renaming the admin directory in your installation, and putting that
// new name here. eg "moodleadmin". This will fix admin links in Moodle.
$CFG->admin = 'admin';
//=========================================================================
// 7. OTHER MISCELLANEOUS SETTINGS (ignore these for new installations)
//=========================================================================
//
// These are additional tweaks for which no GUI exists in Moodle yet.
//
//
// Prevent users from updating their profile images
// $CFG->disableuserimages = true;
//
// Prevent scheduled backups from operating (and hide the GUI for them)
// Useful for webhost operators who have alternate methods of backups
// $CFG->disablescheduledbackups = true;
//
// Prevent stats processing and hide the GUI
// $CFG->disablestatsprocessing = true;
//
// Set global password for "Login as", teacher is prompted only once in each session.
// Set your own password and tell it only to teachers that should have access to this feature.
// $CFG->loginaspassword = 'yoursharedpassword';
//
// Setting this to true will enable admins to edit any post at any time
// $CFG->admineditalways = true;
//
// These variables define DEFAULT block variables for new courses
// If this one is set it overrides all others and is the only one used.
// $CFG->defaultblocks_override = 'participants,activity_modules,search_forums,admin,
course_list:news_items,calendar_upcoming,recent_activity';
//
// These variables define the specific settings for defined course formats.
// They override any settings defined in the formats own config file.
// $CFG->defaultblocks_site = 'site_main_menu,admin,
course_list:course_summary,calendar_month';
// $CFG->defaultblocks_social = 'participants,search_forums,calendar_month,calendar_upcoming,
social_activities,recent_activity,admin,course_list';
// $CFG->defaultblocks_topics = 'participants,activity_modules,search_forums,admin,
course_list:news_items,calendar_upcoming,recent_activity';
// $CFG->defaultblocks_weeks = 'participants,activity_modules,search_forums,admin,
course_list:news_items,calendar_upcoming,recent_activity';
//
// These blocks are used when no other default setting is found.
// $CFG->defaultblocks = 'participants,activity_modules,search_forums,admin,
course_list:news_items,calendar_upcoming,recent_activity';
//
//
// This setting will put Moodle in Unicode mode. Please note that database must support it.
// Do not enable this if your database in not converted to UTF-8!
// $CFG->unicodedb = true;
//
// Allow unicode characters in uploaded files, generated reports, etc.
// This setting is new and not much tested, there are known problems
// with backup/restore that will not be solved, because native infozip
// binaries are doing some weird conversions - use internal PHP zipping instead.
// NOT RECOMMENDED FOR PRODUCTION SITES
// $CFG->unicodecleanfilename = true;
//
// Seconds for files to remain in caches. Decrease this if you are worried
// about students being served outdated versions of uploaded files.
// $CFG->filelifetime = 86400;
//
// This setting will prevent the 'My Courses' page being displayed when a student
// logs in. The site front page will always show the same (logged-out) view.
// $CFG->disablemycourses = true;
//
// If this setting is set to true, then Moodle will track the IP of the
// current user to make sure it hasn't changed during a session. This
// will prevent the possibility of sessions being hijacked via XSS, but it
// may break things for users coming using proxies that change all the time,
// like AOL.
// $CFG->tracksessionip = true;
//
//
// The following lines are for handling email bounces.
// $CFG->handlebounces = true;
// $CFG->minbounces = 10;
// $CFG->bounceratio = .20;
// The next lines are needed both for bounce handling and any other email to module processing.
// mailprefix must be EXACTLY four characters.
// Uncomment and customise this block for Postfix
// $CFG->mailprefix = 'mdl+'; // + is the separator for Exim and Postfix.
// $CFG->mailprefix = 'mdl-'; // - is the separator for qmail
// $CFG->maildomain = 'youremaildomain.com';
//
// The following setting will tell Moodle to respect your PHP session
// settings. Use this if you want to control session configuration
// from php.ini, httpd.conf or .htaccess files.
// $CFG->respectsessionsettings = true;
//
// This setting will cause the userdate() function not to fix %d in
// date strings, and just let them show with a zero prefix.
// $CFG->nofixday = true;
//
// This setting will make some graphs (eg user logs) use lines instead of bars
// $CFG->preferlinegraphs = true;
//
// Enabling this will allow custom scripts to replace existing moodle scripts.
// For example: if $CFG->customscripts/course/view.php exists then
// it will be used instead of $CFG->wwwroot/course/view.php
// At present this will only work for files that include config.php and are called
// as part of the url (index.php is implied).
// Some examples are:
// http://my.moodle.site/course/view.php
// http://my.moodle.site/index.php
// http://my.moodle.site/admin (index.php implied)
// Custom scripts should not include config.php
// Warning: Replacing standard moodle scripts may pose security risks and/or may not
// be compatible with upgrades. Use this option only if you are aware of the risks
// involved.
// Specify the full directory path to the custom scripts
// $CFG->customscripts = '/home/example/customscripts';
//
// Performance profiling
//
// If you set Debug to "Yes" in the Configuration->Variables page some
// performance profiling data will show up on your footer (in default theme).
// With these settings you get more granular control over the capture
// and printout of the data
//
// Capture performance profiling data
// define('MDL_PERF' , true);
//
// Capture additional data from DB
// define('MDL_PERFDB' , true);
//
// Print to log (for passive profiling of production servers)
// define('MDL_PERFTOLOG' , true);
//
// Print to footer (works with the default theme)
// define('MDL_PERFTOFOOT', true);
//
// Force displayed usernames
// A little hack to anonymise user names for all students. If you set these
// then all non-teachers will always see these for every person.
// $CFG->forcefirstname = 'Bruce';
// $CFG->forcelastname = 'Simpson';
//
// The following setting will turn SQL Error logging on. This will output an
// entry in apache error log indicating the position of the error and the statement
// called. This option will action disregarding error_reporting setting.
// $CFG->dblogerror = true;
//
// The following setting will turn on username logging into Apache log. For full details regarding setting
// up of this function please refer to the install section of the document.
// $CFG->apacheloguser = 0; // Turn this feature off. Default value.
// $CFG->apacheloguser = 1; // Log user id.
// $CFG->apacheloguser = 2; // Log full name in cleaned format. ie, Darth Vader will be displayed as darth_vader.
// $CFG->apacheloguser = 3; // Log username.
// To get the values logged in Apache's log, add to your httpd.conf
// the following statements. In the General part put:
// LogFormat "%h %l %{MOODLEUSER}n %t \"%r\" %s %b \"%{Referer}i\" \"%{User-Agent}i\"" moodleformat
// And in the part specific to your Moodle install / virtualhost:
// CustomLog "/your/path/to/log" moodleformat
// CAUTION: Use of this option will expose usernames in the Apache log,
// If you are going to publish your log, or the output of your web stats analyzer
// this will weaken the security of your website.
//
// Email database connection errors to someone. If Moodle cannot connect to the
// database, then email this address with a notice.
//
// $CFG->emailconnectionerrorsto = 'your@emailaddress.com';
//
// Restore pre-1.6 behaviour where courses could still be available
// even if the category they were in was hidden
// $CFG->allowvisiblecoursesinhiddencategories = true;
//
// NOTE: if you are using custompix in your theme, see /fixpix.php.

// ALL DONE! To continue installation, visit your main page with a browser
