Simple private wiki
For the common use case of "a private wiki, for oneself and approved others", you need to:


 * Restrict viewing
 * Restrict editing
 * Restrict account creation

Depending on what extensions you have installed, you may want to whitelist more pages. For example if you are using the extension, you probably want Special:RequestAccount whitelisted. If the content language of your wiki is not English, you may have to use the translated name of the special pages in question.

Restrict account creation
To restrict account creation, you need to edit LocalSettings.php in the root path of your MediaWiki installation.

Note you need or else the sysop must pick a password and send it to the user. The user will be requested to change password at first login; when they do this, the email address will also be marked as confirmed.
 * 1) Go to, when logged in as a sysop.
 * 1) Click on "Create an account" link to get to the account creation form.
 * 1) Enter a username and an email address, and click the "by email" button.
 * 1) The account will be created with a random password which is then emailed to the given address (as with the "forgot password" feature).
 * When you click the "create account" button instead, you have to manually send the user their password. If you've set (default configuration up to version 1.15) and you've left the password field blank, the user will be emailed an email address confirmation request but will be unable to access  to perform the confirmation. Instead, the user will get an error (unless you've added it to ); the user will be able to login with a blank password and then confirm email, but their password will not have been reset (it will have to be reset manually).

It may be appropriate to edit the text displayed when a non-user attempts to log in. This can be done at MediaWiki:Nosuchuser, when logged in as a sysop. Use plain text without any special formatting, as the formatting is ignored and the text is literally rendered. (Might have changed, see bug 12952).

You may also modify the contents of the email sent to new users by editing the page MediaWiki:Createaccount-text.

To prevent even sysops from creating accounts:

To add a message on top of the login form, modify MediaWiki:Loginprompt.

Restrict editing of all pages
Users will still be able to read pages with these modifications, and they can view the source by using Special:Export/Article name or other methods. bug 1859 も参照してください.

および を参照してください. If you use, any wiki admin can also put various restrictions in place.

Some examples of how to protect all pages from editing (not reading) by certain classes of users:

Restrict anonymous editing
Requires that a user be registered before they can edit.

Restrict editing by all non-sysop users
Requires that a user be a member of the administrators (sysop) usergroup.

Restrict editing of an entire namespace
Starting from MediaWiki version 1.10, it is possible to protect entire namespaces using the variable. 例:

Note that in the last case it's assumed that a custom namespace exists and that  is a defined constant equal to the namespace number. See Manual:Using custom namespaces and Manual:Namespace_constants for a list of MediaWiki's core namespaces.

Restrict editing of certain specific pages
Use the feature. By default, any sysop can protect pages so only other sysops can edit them. In 1.9 and higher, by default they can also protect pages so only "autoconfirmed" users (with accounts older than a configured period) can edit them. This does not require editing configuration files.

If you want to restrict editing to groups with specific permissions, edit. To prevent actions other than edit and move, use.

Restrict editing of all but a few pages
To impose a blanket restriction on editing for all pages, but allow a few (such as sandboxes, join request pages, etc.) to be more generously editable, you can use the extension. This may not fit too often, but you could also use the Restrict editing of certain specific pages method mentioned above, with all name spaces protected, and only a special one editable by everyone which has all the pages you want editable.

Restrict editing for certain IP address ranges
Schools and other institutions may want to block all edits not from a few specified IP address ranges. To do so, see. The only way to do this at present without modifying the code is to go to Special:Blockip and systematically  every one of the address ranges that you don't want to be able to edit. This will work for all future versions of MediaWiki. It will not work on a per-namespace basis.

Restrict editing by a particular user
Use the user functionality to deprive a user of all edit access. MediaWiki does not include a possibility to give rights to separate users directly; instead rights are always given to a user group. There is no way in the core software to change permissions of particular users in order to restrict or allow editing particular pages, except by changing their usergroup.

Restrict creating pages in certain namespaces
There are separate rights for creating talk pages (createtalk) and creating non-talk pages (createpage). If you need per-namespace control finer than that, it is not possible in core MediaWiki, and requires an extension such as.

Restrict access to uploaded files

 * &rarr;, , 

If you have enabled the ability to upload files, these will be served directly by the underlying web server. As a result, .

Example for access restriction to uploaded files in the server configuration
If sensitive files are uploaded to an internet-accessible wiki, you may wish to add restrictions on where these can be accessed from. On Apache, if your local network were 10.1.2.*, you could restrict serving files to local addresses with:

 Order deny,allow Allow from 10.1.2.3 Deny from all 

Restrict viewing of all pages
Add this line to your LocalSettings.php file:

The  setting allows users to view the main page. If page names have more than one word, use a space " " between them, not an underscore "_".

In addition to the main page of such a private site, you could give access to the Recentchanges page (if you think that its content isn't private) for feed readers by adding "Special:Recentchanges" to.

If you need to protect even the sidebar, main page, or login screen for any reason, it's recommended that you use higher-level authentication such as .htpasswd or equivalent.

いくつかの特定のページの閲覧制限
管理者以外に閲覧をさせないためには、単にページをします. 管理者にも閲覧させない場合は、さらに永久的に削除するためを使います. 特定ページの記述内容を完全に破壊するには、データベースから手動で削除できます. いずれの場合も、この状態のページは編集ができず、ほとんどの目的に使おうにも、ページが存在していません.

To have a page act normally for some users but be invisible to others, as is possible for instance in most forum software, is a very different matter. MediaWiki is designed for two basic access modes:

This is the mode used by Wikipedia and its sister projects. This is basically the same as the above, in terms of technical implementation (just an extra check for every page view), which is why it exists. This is the mode of operation used by certain private wikis such as those used by various Wikimedia committees.
 * 1) Everyone can view every single page on the wiki (with the possible exception of a few special pages).
 * 1) Anonymous users can only view the Main Page and login page, and cannot edit any page.

''' If you intend to have different view permissions than that, MediaWiki is not designed for your usage. ''' (T3924 を参照してください. ) Data is not necessarily clearly delineated by namespace, page name, or other criteria, and there are a lot of leaks you'll have to plug if you want to make it so (see  for a sample). Other wiki software may be more suitable for your purpose. You have been warned. If you must use MediaWiki, there are three basic possibilities:

See the section above. You will have to reapply it every time you upgrade the software, and it may not be updated immediately when new security fixes or upgrades of MediaWiki are released. Third-party hacks are, of course, not supported by MediaWiki developers, and if you're having problems you shouldn't ask on MediaWiki-l, #mediawiki, or other official support channels. A number of hacks are listed in. Read about if you plan to use one of those.
 * 1) Set your wiki up private and whitelist specific pages that will be public with   in the LocalSetting.php file.
 * 1) Set up separate wikis with a, configure one as viewable and one as unviewable (see above), and  between them.
 * 1) Install a third-party hack or extension.

書き出しの制限
関連項目: 

It is not possible to export the contents of a page that cannot be read since.

ログインのリンクをすべてのページから除去
One can remove the login/create account link from the upper right corner of all pages, as users can still go to Special:SpecialPages>Special:UserLogin to login. In LocalSettings.php use (tested with MediaWiki 1.16)

アカウントの削除
If you want to completely remove access to a user, e.g. on a simple private wiki, it's not possible to simply delete the account ; you can it, but the user will still  to read pages. However, using extension you can merge the account in another one and delete the former; the original account will then "disappear". If you want to preserve history readability (i.e., to have edits from the user to be still shown under their name), you can create a new account e.g. with username "OriginalUserName (deactivated)" and then merge "OriginalUserName" into the former, or even use extension to rename "OriginalUserName" into "AnotherUserName", then create an account under "OriginalUserName" and merge "AnotherUserName" into it: in this manner, "OriginalUserName" will be completely "usurped" (if you've set a non-null password).

MediaWiki 1.16.0 以降は を true に設定してブロック済み利用者のアクセスと表示を予防できるようになりました.

その他の制限事項
ページ編集をそのページの作者にのみ認める場合、あるいは編集履歴の秘匿ほか、その他の制限をかけたい場合があるとします. MediaWiki の標準版では、これらを実現する機能はありません. さらにきめ細かい権限設定が必要な場合は、#関連項目節にあるリンク先から、他のウィキパッケージでこの機能を備えたもの、あるいは MediaWiki を本来の設計趣旨とは外れるけれども、使える形に変えるハッキングを参照できます.

他のウィキソフトウェアのほうがMediaWikiよりもきめの細かいアクセス制限を支援する場合があります.


 * MoinMoin
 * TWiki
 * TikiWiki - 機能や権限レベルでアクセス制限の設定が完全にできます.

もっとアクセス制限を向上させたいけれど MediaWiki で実現したい場合、この拡張機能一覧とハッキングでソフトウェアの標準ではできない制限が可能です. ただしハッキングが古すぎる可能性もあります(バージョン情報を要確認. ) 第三者のハッキングでなにか障害が出ても、MediaWiki の公式サポートで質問はできません.
