Θα πρέπει να αφιερώσετε χρόνο για να ελέγξετε τις ρυθμίσεις σε αυτό το αρχείο.
Το αρχείο δημιουργείται συνήθως από το πρόγραμμα εγκατάστασης MediaWiki που βασίζεται στον ιστό, αλλά μπορείτε να τροποποιήσετε τις παραμέτρους, πιθανώς σε συνεννόηση με τις ρυθμίσεις του Apache.
Για εγκαταστάσεις MediaWiki που έχουν διαμορφωθεί ως [[Special:MyLanguage/Manual:Wiki family|φάρμα wiki]], μπορεί να χρησιμοποιηθεί ένα αρχείο με όνομα <code>{{ll|Manual:CommonSettings.php|CommonSettings.php}}</code>.

===Διάδρομος προσθήκης (Include path)===
</div>
<span lang="en" dir="ltr" class="mw-content-ltr">The '''{{ll|Manual:$IP|$IP}}''' (install path) variable holds the local file path to the base installation of your wiki.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Since MediaWiki 1.18, the system sets $IP automatically.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Setting {{phpi|$IP}} manually in <code>LocalSettings.php</code> is no longer needed.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">{{phpi|$IP}} will default to the current working directory and can be used without the need to manually define it.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Attempting to set {{phpi|$IP}} (or <code>MW_INSTALL_PATH</code>) in <code>LocalSettings.php</code> may produce unexpected results.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
The {{ll|Manual:DefaultSettings.php|DefaultSettings.php}} file gets loaded from the directory designated by the IP variable.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Site name===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgSitename|$wgSitename}}''' holds the name of your wiki setup. This name gets included many times throughout the system, such as via MediaWiki:Pagetitle. For instance, the Wikipedia tagline "From Wikipedia, the free encyclopedia" makes use of this setting.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Declensions of site name ===

<span lang="en" dir="ltr" class="mw-content-ltr">Some translations of interface are ready for inflection of site name.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">You can set proper forms of word in variables '''{{ll|Manual:$wgGrammarForms|$wgGrammarForms}}''' (for example please refer to the '''{{ll|Manual:$wgSitename|$wgSitename}}''' documentation page).</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Site language===
</div>
<span lang="en" dir="ltr" class="mw-content-ltr">'''{{ll|Manual:$wgLanguageCode|$wgLanguageCode}}''' controls the language of your wiki's interface.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">While users can switch the language they see in their [[Special:Preferences|preferences]], this variable sets the default language that all anonymous users and most registered users see.</span> 

<div lang="en" dir="ltr" class="mw-content-ltr">
===Script path===
</div>
<span lang="en" dir="ltr" class="mw-content-ltr">'''{{ll|Manual:$wgScriptPath|$wgScriptPath}}''' is the URL path prefix to access the main MediaWiki script that is the central acting piece of code of MediaWiki.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">This setting should correspond to the [[Special:MyLanguage/Apache configuration|Apache settings]], especially if you are using Apache's [[w:Rewrite_engine|rewrite]] rules.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Server name===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgServer|$wgServer}}''' contains the base URL of the server, including protocol but without the trailing slash and without the subdirectory if any. When the wiki is accessed from either the localhost where it runs, from an intranet or from the internet, email notifications and a few other computed messages would be usually delivered with the different URLs.
</div>

<span lang="en" dir="ltr" class="mw-content-ltr">From MediaWiki 1.34 {{phpi|$wgServer}} must be set in LocalSettings.php.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Prior to that, MediaWiki tried to autodetect the name of the server and {{phpi|$wgServer}} was optional, to override the autodetection.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
If www.example.com is the server address of your wiki as seen from the internet, add a line such as
</div>

<syntaxhighlight lang="php">
$wgServer = 'http://www.example.com';
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
The [[m:Special:MyLanguage/Help:Magic words#Page names and related info|magic word]] variable <code><nowiki>{{SERVER}}</nowiki></code> can be used on wiki pages; it equals the value of {{phpi|$wgServer}}; however, on a wiki, such as those in the Wikimedia family, where relative urls are used, it will not fully expand, for example here it displays {{SERVER}}, which can neither be clicked nor copy-pasted into the address bar as it is.
</div>

<span lang="en" dir="ltr" class="mw-content-ltr">You can also use a protocol relative URL as shown below.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">When using a protocol relative URL, be sure to set {{phpi|$wgCanonicalServer}}.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">{{phpi|$wgCanonicalServer}} is needed for some places in the code where an origin with a protocol and hostname is needed.</span>

<syntaxhighlight lang="php">
$wgServer = '//www.example.com';
$wgCanonicalServer = 'https://www.example.com';
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Script name===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgScript|$wgScript}}''' is the name of the main (index) MediaWiki PHP script, named <code>index.php</code> by default. Changing the script name is probably not a good idea. However, if you feel the urge to do so, this is the place to make your changes. Make sure you know what you are doing.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Article path===
</div>
<span lang="en" dir="ltr" class="mw-content-ltr">'''{{ll|Manual:$wgArticlePath|$wgArticlePath}}''' is the path to use when accessing a page in MediaWiki.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">The path should contain the path to the main script (usually making use of {{phpi|$wgScript}}) and use the <code>$1</code> placeholder for the article name.</span>

<span lang="en" dir="ltr" class="mw-content-ltr">If you are using Apache rewrite rules to create pretty and short URLs, you probably need to adjust {{phpi|$wgArticlePath}} to address the right path.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Note that wgArticlePath is used to construct URLs from within MediaWiki.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">If you make a mistake here, internal links will show up incorrectly while you still may be able to access the main page by specifying the correct URL manually.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">See {{ll|Manual:Short URL}} for more information on URL configuration.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
Typical values are:
</div>

{| class="wikitable"
| <code>"$wgScript/$1"</code>
| <span lang="en" dir="ltr" class="mw-content-ltr">pass the article name with separator "/"</span>
|-
| <code>"$wgScript?title=$1"</code>
| <span lang="en" dir="ltr" class="mw-content-ltr">pass the article name as a parameter (old style)</span>
|-
| <code>"/mypath/$1"</code>
| <span lang="en" dir="ltr" class="mw-content-ltr">custom path. Use Apache rewrite rules to convert "mypath" to the proper path accessing the main script</span>
|}

<div lang="en" dir="ltr" class="mw-content-ltr">
===Stylesheet location===
</div>
<span lang="en" dir="ltr" class="mw-content-ltr">Use '''{{ll|Manual:$wgStylePath|$wgStylePath}}''' to set the URL path to the place where the stylesheets (CSS) for the MediaWiki installation are located.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">'''{{ll|Manual:$wgStyleDirectory|$wgStyleDirectory}}''' should point the same place, but note that this is a local file system path for use in internal scripts accessing the file system.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Upload location===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The upload directory is the place where files uploaded by the users are stored. '''{{ll|Manual:$wgUploadPath|$wgUploadPath}}''' specifies the URL path, '''{{ll|Manual:$wgUploadDirectory|$wgUploadDirectory}}''' points to the local file system path.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Logo===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgLogo|$wgLogo}}''' specifies which graphical logo is displayed in the top left corner of all MediaWiki pages. These steps replace the default logo in the /wiki/skins/common/images/ directory, replacing /wiki with the path to the directory where you installed the MediaWiki software.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
First, copy whatever logo you want into the /wiki/skins/common/images/ directory (replacing /wiki with the path to the directory where you installed the MediaWiki software).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Next, try to find the line that looks like this in <code>LocalSettings.php</code>:
</div>

<syntaxhighlight lang="php" style="overflow:auto;">
$wgLogo = "$wgStylePath/common/images/wiki.png";
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
If there's no such line, you can copy and paste the line above at the end of the file.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Then, modify that line to point to your logo. The logo must be web accessible. The value of this variable is passed to the web browser, which uses it to fetch the logo. If in doubt, a good way to pick what to put here is navigate to the logo in your web browser (for example, this wiki the url of the logo is http://upload.wikimedia.org/wikipedia/mediawiki/b/bc/Wiki.png ), and put the full URL as the value of this variable.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Some people just replace the skins/common/images/wiki.png file with their logo. This is not recommended, as the customized logo would be overwritten on upgrade.
</div>

<span lang="en" dir="ltr" class="mw-content-ltr">MediaWiki 1.35 introduced {{ll|Manual:$wgLogos|$wgLogos}}, which allows multiple versions of the same logo.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">An example of using multiple logos is shown below.</span>

<syntaxhighlight lang="php" style="overflow:auto;">
$wgLogos = [
	'1x' => "$wgStylePath/common/images/1x_version.png",
	'1.5x' => "$wgStylePath/common/1.5x_version.png",
	...
	'tagline' => [
		'src' => "$wgStylePath/common/tagline_version.png",
		'width' => 135,
		'height' => 15,
	],
];
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Contact info===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgEmergencyContact|$wgEmergencyContact}}''' is the email address of the user to contact if something goes wrong. This email address is used to send internal bug reports to. As an administrator, you want to include your email address here.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgPasswordSender|$wgPasswordSender}}''' is the email address where email gets sent ''from'', when passwords are sent out to users who have forgotten their passwords. Choose an address people can reply to in case of trouble or confusion.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Database settings===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
MediaWiki needs access to the database (currently either [[w:MySQL|MySQL]] or [[w:PostgreSQL|PostgreSQL]]) to store pages, modifications, user information, and a lot more things.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgDBserver|$wgDBserver}}''' contains the hostname where the database is hosted on. In most cases this will be just "localhost" as the database is run on the same system, but for distributed installations, you need to fill in the fully qualified domain name of the computer running the database.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgDBname|$wgDBname}}''' is the ''database name'' of the database to be used by MediaWiki. A single MySQL or PostgreSQL installation can store more than one database and you can even run many MediaWiki installations on a single server. Make sure you have stated the correct database name here and use different database names for different wiki installations on the same database server.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgDBuser|$wgDBuser}}''' and '''{{ll|Manual:$wgDBpassword|$wgDBpassword}}''' contain the login name and password to be used by MediaWiki to access the database. Make sure the specified user has the proper access rights to be able to manipulate the wiki's table on the database server.
</div>

<span lang="en" dir="ltr" class="mw-content-ltr">Also see {{ll|Manual:Securing database passwords}} for a method to move the sensitive parts of <code>LocalSettings.php</code> to a different file in a different directory.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
===User rights===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''{{ll|Manual:$wgGroupPermissions|$wgGroupPermissions}}''' is an associative array, controlling permissions for creating and editing pages for your different user groups. In this array, custom permission levels can be created, and permission levels for the different user groups can be set. See {{ll|Help:User rights}} for more information about the different permissions and user groups available.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Force capital links===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
By default, no page name can start with a lowercase [[w:Latin alphabet|Roman letter]]: in an attempt to do so the first letter is converted to uppercase; if a link target, included page, image or category is specified with a name starting with a lowercase letter, the actual target etc. is the page starting with the corresponding capital.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Alternatively page names ''can'' start with a lowercase letter, in addition to the possibilities of starting with a capital, a digit, etc. For that you must adjust '''{{ll|Manual:$wgCapitalLinks|$wgCapitalLinks}}'''. Setting it to '''false''' allows lowercase characters, '''true''' chooses the default behavior.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Enabling subpages===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
In <code>LocalSettings.php</code>, [[Special:MyLanguage/Help:Subpages|subpages]] are enabled on a per-namespace basis using '''{{ll|Manual:$wgNamespacesWithSubpages|$wgNamespacesWithSubpages}}'''. For example, to enable subpages in the main namespace:
</div>

<syntaxhighlight lang="php">
$wgNamespacesWithSubpages[NS_MAIN] = 1;
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
===Image uploads===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Before users are allowed to upload files to the MediaWiki system, you have to enable that feature. Make sure the Upload Directory is properly configured and writeable by the Apache web server process. Then set '''{{ll|Manual:$wgEnableUploads|$wgEnableUploads}}''' to '''true''' to allow uploading in the web user interface.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
i.e. Here's some example code from ''includes/DefaultSettings.php'' to put in <code>LocalSettings.php</code>:
</div>

<syntaxhighlight lang="php" style="overflow:auto;">
$wgUploadPath       = "$wgScriptPath/uploads";      ## Wiki 1.5 defaults to /images, but allows more than just images
$wgUploadDirectory  = "$IP/uploads";                ## Wiki 1.5 defaults to /images, but allows more than just images

## To enable image uploads, make sure the above '$wgUploadPath' directory is writable by Apache User or group.
## ''(i.e.  chmod og+w uploads images)''  then the following should be true:
$wgEnableUploads       = true;

$wgUseImageMagick      = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";

## If you want to use image uploads under safe mode, create the directories images/archive, images/thumb and
## images/temp, and make them all writable. Then uncomment this, if it's not already uncommented:
$wgHashedUploadDirectory = false;
</syntaxhighlight>

<span lang="en" dir="ltr" class="mw-content-ltr">If you want to be able to resize images on the fly to support thumbnails, MediaWiki needs a working [[w:ImageMagick|ImageMagick]] installation.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Set '''{{ll|Manual:$wgUseImageMagick|$wgUseImageMagick}}''' to '''true''' once you have installed and tested ImageMagick on your system.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">Make sure '''{{ll|Manual:$wgImageMagickConvertCommand|$wgImageMagickConvertCommand}}''' points to the proper location of the <code>convert</code> command of your installation, that the command is executable by the web server process, and '''{{ll|Manual:$wgMaxShellMemory|$wgMaxShellMemory}}''' is large enough.</span>
<span lang="en" dir="ltr" class="mw-content-ltr">See {{ll|Manual:Image administration#Image thumbnailing|Manual:Image administration#Image thumbnailing}} for detailed information and troubleshooting.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
Also, you may want to modify the list of accepted extensions, which is stored within '''{{ll|Manual:$wgFileExtensions|$wgFileExtensions}}''':
</div>

<syntaxhighlight lang="php">
$wgFileExtensions = [ 'png', 'jpg', 'jpeg', 'ogg', 'doc', 'xls', 'ppt', 'mp3', 'sxc', 'pdf' ];
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
In case ImageMagick outputs an error message similar to the following:
</div>

<blockquote>
<span lang="en" dir="ltr" class="mw-content-ltr">Fatal error: mime_magic could not be initialized, magic file is not available in includes/MimeMagic.php on line 506</span>
</blockquote>

<div lang="en" dir="ltr" class="mw-content-ltr">
then try adding the following line to <code>LocalSettings.php</code>:

===Language of user interface===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
MediaWiki allows for a variety of localized user interfaces languages instead of the English default. If you want to run your wiki in a non-English language, set the {{wg|LanguageCode}} variable to the proper [[Special:SiteMatrix|language code]] (e.g. "de" for German, "es" for Spanish, etc.)
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
You may use any of the languages with a file in the directory {{git file |file=languages/i18n}}. E.g. if you find <code>es.json</code>, then you can use <code>"es"</code> for Spanish. Do not use <code>"Es"</code> with a capital letter. Although it seems to work, not all texts are translated.
</div>

{{note|1=<span lang="en" dir="ltr" class="mw-content-ltr">After changing the language code, you will need to run a PHP script to make it work.</span> <span lang="en" dir="ltr" class="mw-content-ltr">In a terminal window, change to your wiki directory, change to the <code>maintenance</code> folder, and enter <syntaxhighlight lang=bash inline>php rebuildMessages.php --rebuild</syntaxhighlight>.</span> <span lang="en" dir="ltr" class="mw-content-ltr">On Windows, the PHP folder might not be in your <code>PATH</code> environment variable and you'll have to prefix <kbd>php</kbd> with the path to the program.</span>}}

<span lang="en" dir="ltr" class="mw-content-ltr">See the [https://translatewiki.net/w/i.php?title=Special:MessageGroupStats&group=mediawiki translation statistics on TranslateWiki] for an up-to-date list of which languages are supported and to what extent.</span>

===Setting copyright for the site===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''{{ll|Manual:$wgRightsPage|$wgRightsPage}}''' is the page on the wiki that covers the copyrights that it falls under. Usually, this will be {{ll|Project:Copyrights}}.

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''{{ll|Manual:$wgRightsUrl|$wgRightsUrl}}''' is the page describing full details of your license. (For the GNU FDL, for example, this would be <code>http://www.gnu.org/licenses/fdl.html</code>.)
</div> 
<div lang="en" dir="ltr" class="mw-content-ltr">
* '''{{ll|Manual:$wgRightsText|$wgRightsText}}''' is the text in the footer that follows "Content is available under". It will be linked to the page specified in <code>$wgRightsPage</code>.

<div lang="en" dir="ltr" class="mw-content-ltr">
To modify the copyright statements of the site, add something like this to <code>LocalSettings.php</code>:

$wgRightsPage = "YourWiki:Copyright";
$wgRightsText = "copyright YourWiki";
</syntaxhighlight>

<div lang="en" dir="ltr" class="mw-content-ltr">
