PostgreSQL를 사용한다면, Manual:Upgrading PostgresManual:Upgrading Postgres를 읽으시오.

더 자세한 정보를 원한다면, Manual:Installation requirements/koManual:Installation requirementsCompatibilityCompatibility를 읽으시오.

배포 통지문 읽기[edit]

배포 tar파일 내에 혹은 Git를 통해 추출된 파일 내에 대문자로 쓰인 다수의 파일명들이 있습니다. 그 중에 RELEASE-NOTES(배포 통지문)(wiki)이 있습니다. 파일을 찾았다면 바로 배포 당시 어떤 부분이 바뀌었는지 확인하십시오.

보류된 작업 없애기[edit]

수행능력의 이유로 데이터 베이스의 어떤 동작들이 지연되고, 작업 대기 행렬에 의해 관리됩니다. 이 작업들은 데이터베이스에 저장되어 있고, 어떤 액션을 취해야 하는지에 대한 매개 변수를 포함하고 있습니다. 위키를 업데이트하기 전에 이 보류된 작업들을 처리하는 것을 강력히 권장합니다. 그렇지 않으면 새 버전에서 이 작업들의 매개 변수의 세목이 바뀌어, 작업을 더 이상 할 수 없게 될 수 있기 때문입니다. runJobs.phpManual:RunJobs.php를 사용하여 모든 보류된 작업을 처리하고, 대기 행렬을 소거한 후 업데이트를 시작하십시오.

이전 파일과 데이터 베이스 백업하기[edit]

지시사항 일체는 Manual:위키를 백업하는 법Manual:Backing up a wiki을 참고하시오

비록 업그레이드 스크립트는 잘 관리되고 안정적이지만, 항상 문제는 발생할 수 있습니다. 데이터베이스 스키마를 업데이트를 진행하기 앞서, 데이터 베이스를 포함하여 위키의 전체 파일을 백업하십시오.

  • 데이터 베이스를 포함한 위키의 내용 (문자 세트가 정확히 지정되었는지를 확실히 하기 위해 LocalSettings.php를 확인하십시오.). SQL 데이터베이스 덤프와 더불어 XML 덤프를 만드는 것을 추천합니다.
  • MySQL, SQL 덤프와 XML 덤프 둘 다 mysql 명령어를 위한 용도입니다.
mysqldump --user=wikidb_user --password=wikidb_userpassword wikidb > file.sql
mysqldump --user=wikidb_user --password=wikidb_userpassword wikidb --xml > file.xml
  • PostgreSQL, 데이터베이스 덤프는 pg_restore를 위한 용도입니다.
pg_dump --create -Fc wikidb > file.db.dump
  • SQLite, 미디어위키 스크립트를 백업 파일을 만드는데 사용합니다.
php wikifolder/maintenance/sqlite.php --backup-to file
  • 이미지와 다른 미디어 파일들 (images 폴더에 있는 내용물들,과 커스텀 로고 /skins/common/images/wiki.png)
  • 구성 파일들. 예를 들어 LocalSettins.php.htaccess (있다면)
  • 스킨과 확장 프로그램들을 포함한 미디어위키 프로그램 파일들. (별다른 수정을 하지 않았다면 백업하지 않아도 괜찮음).

새 파일의 압축 풀기[edit]

tarball 패키지를 사용하기[edit]

새 파일은 FTP나 명령어를 입력하여 옮길 수 있습니다. 접근 가능하다면 명령어를 입력하십시오! FTP를 이용하여 수천개의 파일을 업로드하는 것도 명령어를 이용하는 것이 훨씬 빠릅니다.

주의 주의: You should put the decompressed tarball in a new and empty folder on your server. If you instead extract the new version directly on top of your old version, rather than in a new directory, you should follow the instructions described in Back up existing files and the database: otherwise, if you've made any customizations you may erase them in a way that leaves you with no reference to re-apply them from. Extracting a tarball over top of your live copy of MediaWiki can also leave behind files from the old version of MediaWiki which may interfere with the upgraded code. It's recommended that you unpack the new files into a new directory, and then apply customizations to the new directory (restoring LocalSettings.php, images folder, extensions, and other customizations like custom skins)

FTP or graphical[edit]

If you cannot access the command line on your server, download the MediaWiki tarball to your local computer and use 7zip to extract the tarball on your local PC.

After you extracted the files locally, use your favorite FTP client software to upload directories and files to the server.

= 명령어[edit]

You may need to run the command as sudo if you don't have full write permissions to the wiki install directories under your current user. When untarring a tarball package normally a new directory for the new wiki version will be created and you will have to copy the old configuration files and images directory from your old installation directory:

$ cd /path/to/your/new/installation/  
$ wget https://releases.wikimedia.org/mediawiki/1.29/mediawiki-1.29.0.tar.gz
$ tar -xvzf mediawiki-1.29.0.tar.gz 
$ rm mediawiki-1.29.0.tar.gz

(Open)Solaris users should use gtar, or:

$ gzip -dc mediawiki-1.29.0.tar.gz | tar xf -

기타 파일[edit]

After extracting the tarball, you should copy or move some files and folders from the old installation directory to the new one:

  • LocalSettings.php, which contains your old configuration settings.
  • The images (or uploads in older versions) directory, which contains all the uploaded files to the wiki, unless you have chosen a different upload directory, and change the ownership and permissions. find ./images -type d -exec chmod 755 {} \; and chgrp -R apache images (e.g. if your web user is apache).
  • Some extensions in the extensions directory. You should always get updated extensions, old extensions aren't guaranteed to work with a newer version of MediaWiki.
  • In case you use a custom logo this file also needs to be restored from backup. Before 1.24 usually in skins/common/images/. After 1.24 in resources/assets/ or images/ if that's what you chose to use. Then add to LocalSettings.php e.g. $wgLogo = "$wgScriptPath/images/logo.png";
  • Custom skins from within the skins directory.
  • Any modifications made to the old installation files or extensions.
  • Any .htaccess file (if you're using Apache and you've defined any rules in them).

Once done, make this new folder the published folder on the web server, or rename the old installation directory and then rename the new one to match the old name.

Git 이용하기[edit]

If using GitDownload from Git, export the files into a clean location, and then copy the old customized files into the new location as described in the previous section.

If you are upgrading to MediaWiki 1.25 or later, you will also need to install some external PHP libraries using Composer or a provided collection maintained for the Wikimedia wiki farm. More details on installing and updating external libraries can be found in the Git download documentation.

Using patch[edit]

A small patch file is usually made available for a minor version upgrade. Manually download and extract the patch file from the dumps site or follow the directions with wget below. Patches are incremental, you can not skip a version.

  1. cd to your main MediaWiki directory (the one with LocalSettings.php).
  2. Download the patch file and gunzip it.
  3. Use patch -p1 --dry-run to check what will be changed (e.g., patch -p1 --dry-run -i mediawiki-x.xx.x.patch)
  4. If all is well, run patch again without --dry-run.
  5. Check your Special:Version and you should see the new version number in place.

Files remaining that may cause errors[edit]

If you unpacked over the old installation directory, some old files can cause problems with the new version.


MediaWiki version: 1.18

If you are not using profiling, but have a StartProfiler.php file in the MediaWiki root folder, you may receive errors referring to /includes/Profiler.php. Deleting, or renaming, the StartProfiler.php file will resolve this error. The StartProfiler.sample file, also in the MediaWiki root folder, can serve as a template should you enable profiling in the future.


MediaWiki version: 1.23

MediaWiki 1.23 deprecates the skin autodiscovery mechanism of core skin files. After upgrading to this version, you should ensure that the old files Chick.php, Nostalgia.php, Simple.php and Standard.php directly in the skins/ directory as well as the according subfolders inside the skins/ directory got removed. MediaWiki will log warnings if any of them are still found to help you remember. (You will also need to adjust any custom skins to follow a similar convention.) See Manual:Skin autodiscoveryManual:Skin autodiscovery for details.


MediaWiki version: 1.24

MediaWiki 1.24 changes the paths of core skin files. After upgrading to this version, you should ensure that the old files CologneBlue.php, Modern.php, MonoBook.php and Vector.php directly in the skins/ directory are no longer present. See Manual:Skin autodiscoveryManual:Skin autodiscovery for details.

확장기능 업그레이드[edit]

Certain extensions have been updated in order to work with the new version of MediaWiki. Be sure to upgrade to the latest versions of such extensions. You might need to perform manual updates to custom extensions.

Different tarballs include some subsets of extensions and have versioning which helps you upgrade choosing the right one for your MediaWiki core release.

Extension Distributor works well for most people who want a snapshot of extensions that will work with their supported versions of MediaWiki.

If you want a lot of extensions then downloading from Git is probably best.

Adapt your LocalSettings.php[edit]

If you use the same LocalSettings.php from the old version, you may need to adapt it to how new versions handle it:

Skin registration[edit]

Since MediaWiki 1.24, bundled skins like Vector, Monobook, Modern and CologneBlue are no longer part of MediaWiki core, and they need to be registered explicitly in LocalSettings.php to use them, otherwise MediaWiki will warn that you don't have installed skins.

This is what you need to add to LocalSettings.php when upgrading from versions older than 1.24 and want to have available one of those skins:

wfLoadSkin( 'Vector' );
wfLoadSkin( 'MonoBook' );
wfLoadSkin( 'Modern' );
wfLoadSkin( 'CologneBlue' );

This code is for MediaWiki 1.25 and newer. For MediaWiki 1.24 you need to use the following code:

require_once "$IP/skins/Vector/Vector.php";
require_once "$IP/skins/MonoBook/MonoBook.php";
require_once "$IP/skins/Modern/Modern.php";
require_once "$IP/skins/CologneBlue/CologneBlue.php";

Other skins may still not be adapted to the new skin registration system, so refer to the documentation page about each skin to see how to register it properly in case of problems.

Extension registration[edit]

Since MediaWiki 1.25, extensions use a new extension registration system.

Previously your LocalSettings.php would include something like:

require_once "$IP/extensions/Cite/Cite.php";
require_once "$IP/extensions/Gadgets/Gadgets.php";
require_once "$IP/extensions/ImageMap/ImageMap.php";
require_once "$IP/extensions/InputBox/InputBox.php";
require_once "$IP/extensions/Nuke/Nuke.php";
require_once "$IP/extensions/ParserFunctions/ParserFunctions.php";
require_once "$IP/extensions/Poem/Poem.php";
require_once "$IP/extensions/SyntaxHighlight_GeSHi/SyntaxHighlight_GeSHi.php";
require_once "$IP/extensions/WikiEditor/WikiEditor.php";

This can be converted to:

wfLoadExtension( 'Cite' );
wfLoadExtension( 'Gadgets' );
wfLoadExtension( 'ImageMap' );
wfLoadExtension( 'InputBox' );
wfLoadExtension( 'Nuke' );
wfLoadExtension( 'ParserFunctions' );
wfLoadExtension( 'Poem' );
wfLoadExtension( 'SyntaxHighlight_GeSHi' );
wfLoadExtension( 'WikiEditor' );

Extensions are being adapted to use the new extension registration system. Extensions that are not adapted should use the old way of installing them. Refer to the installation instructions on the extension's page for more information.

Other variables[edit]

Some variables may be obsolete or even removed. Having them in LocalSettings.php usually won't have any effect. New variables may be added in newer versions, or some existing variables changed their type. We usually try to use sane defaults for them, and in case of type change, be backwards compatible. In any case, take a look to the release notes to see those changes.

업데이트 스크립트 가동하기[edit]

You can upgrade the MediaWiki database in two ways: Either from the command line or from the web browser. If you have shell access to your server, upgrading from the command line is recommended, since this reduces the risk of the upgrade process being interrupted by a timeout or connection reset.

The script will also attempt to download any missing dependency which MediaWiki needs.

Command line[edit]

Access the command line of your server or an SSH shell or similar. You can access the command line by connecting to your server via SSH. If the local PC you are working on runs Microsoft Windows, you will need a tool like PuTTY to use SSH. From the command line or the Shell, change to the maintenance directory and execute the update script:

$ php update.php

On a Linux server if you get an error try performing the same command as root (sudo php maintenance/update.php). Note for simple installations on Windows (e.g. with XAMPPManual:Installing MediaWiki on XAMPP): First make sure that your web server (such as Apache) and your database (such as MySQL) are running. Then run update.php: right-click it, select Open With, and browse to PHP.exe. The resulting command prompt window will likely autoclose when the schema upgrade completes.

You might see a message that your PHP version is too old and that MediaWiki needs a newer version. After that message the update aborts. Reason for this error is that the command line can use another PHP version than that one which you have when you execute MediaWiki from the web server. When you get this message you should check, if you can execute a newer PHP version on the shell by using a different command: That might e.g. be php5 or php56. If another version is available and - if so - under which name, depends on the setup of your server. If it does not work, ask your hoster; he will surely know.

MediaWiki will inspect the existing schema and update it to work with the new code, adding tables and columns as needed.

If you use a Shared database, you should pass the --doshared parameter if you want the shared tables to be updated. Otherwise they won't be touched by the update script.

What to do in case of "ALTER command denied to user" error (or similar)[edit]

In case the scripts abort with a message similar to:

Error: 1142 ALTER command denied to user 'wiki'@'localhost' for table 'mytable' (localhost)
ERROR: must be the owner of the mytable relation 

This means that you should check that you have defined $wgDBadminuserManual:$wgDBadminuser and $wgDBadminpasswordManual:$wgDBadminpassword in your LocalSettings.phpManual:LocalSettings.php file (in the main directory). These are the user and password needed by this script in order to access to the database.

What to do in case of "unexpected T_STRING" error[edit]

Individuals running update.php from the command line may encounter the following error:

syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' \
in ~/maintenance/commandLine.inc on line 13

This error occurs when update.php is run from php4.

Individuals who have their site hosted by providers who provide both php4 and php5 should take the following steps:

  1. from the command line, enter the command 'whereis php5'
  2. once you have discerned the location of the php5 path, list the contents of php5/bin directory
  3. once you've determined the name of the php executable (either php or php5), type in the entire path to execute update.php

Below is an example:

$ whereis php5
$ ls -la /usr/local/php5/bin
$ /usr/local/php5/bin/php update.php

What to do in case of 'register_argc_argv is set to false' error[edit]

You may encounter the error:

Cannot get command line arguments, register_argc_argv is set to false
  1. Go to ~/maintenance. Either edit an existing 'php.ini' file, or create one.
  2. Add a line as follows:
register_argc_argv=true
  1. Re-run php update.php

웹 브라우저[edit]

MediaWiki version: 1.17
See also update.phpManual:update.php

If your database is already big and in high production usage, then you should not be using the Web updater, e.g. because the update process will time out when the maximum_execution_time is reached. In that case you should use update.php from the command-line interface (not from the web). What exactly is "too big" depends on your server (e.g. on its performance, the load and on how long the maximum execution time of PHP allows the script to run). If your wiki is too big for the web updater and your hosting provider does not allow command-line access, then you need to migrate your wiki to another hosting account, preferably to one that does have shell access.

  1. 항상 백업부터 하고 데이터베이스 관리에 들어가시오.
  2. Navigate your webbrowser to /mw-config/. For example, if your wiki is at http://example.org/w/index.php, then navigate to http://example.org/w/mw-config/.
  3. Select your language and click continue.
  4. The existing installation should be detected. Follow the instructions on the screen to upgrade it.
    If asked for the "upgrade key", open your LocalSettings.phpManual:LocalSettings.php file and look for the key assigned to $wgUpgradeKeyManual:$wgUpgradeKey.

It might happen that the web-updater does not seem to work: Instead of seeing the initial language selection screen, you might see an empty wiki page, possibly with some error message. In this case it is most likely that your webserver uses Rewrite Rules (most likely for short URLs), which do not show you the updater at mw-config/, but a wiki page at Mw-config/, with capital "M". In this case, rename the .htaccess file for the time of the update. Then you should be able to access the web-updater.

경고 경고: If you use this method, make sure to change the name of the .htaccess file back after running the upgrade script! Otherwise short URLs and possibly other stuff will be broken!

자주 묻는 질문[edit]

업그레이드는 얼마나 어렵나요?[edit]

수정한 파일이 LocalSettings.phpManual:LocalSettings.php뿐이며, 현재 위키의 버전이 1.5 이상이라면, 업그레이드 과정은 매우 간단합니다. 사람이 해야 할 일은 고작 몇 번에 불과합니다. 데이터베이스 스키마 관련 업데이트는 데이터 베이스 크기에 따라 걸리는 시간이 달라집니다. 수백만 페이지가 되는 위키라면 수시간이 걸릴 수도 있습니다. 하지만 몇 천 페이지 정도의 대부분의 위키는 일 분도 안 되어서 완료됩니다.

메이저 버전 내 사소한 업데이트(예를 들어 1.13.0에서 1.13.1로 업데이트 하기) 는 스키마 변경도 필요가 없습니다. 파일만 새 버전으로 덮어쓰기 하면 됩니다. 데이터베이스가 업데이트 될 필요가 없으므로, 인스톨러 스크립트도 작동할 필요가 없습니다.

Upgrading from 1.4 or earlier is potentially complicated because support for character sets other than UTF-8 was dropped, and the schema for storing bulk text changed. Please read the relevant section in the UPGRADE file.

Upgrading becomes difficult if you have modified our source code, and you don't want your changes to be overwritten. Tools such as diff, patch, Meld or WinMerge may be useful. There is also potential for trouble if you are using unmaintained extensions. Upgrade your extensions at the same time as you upgrade MediaWiki.

If you have modified the skin or use a custom skin you very likely will have to adjust it to work again with the new version of MediaWiki.

주의 주의: Instead of patching your "global" css and js (javascript) files everytime you can simply add the code to your MediaWiki:Common.js and MediaWiki:Common.css pages. As these are part of the database which will be reused when you upgrade, you will not have to patch the MediaWiki core files any more.

How do I upgrade from a really old version? In one step, or in several steps?[edit]

It depends: If you are upgrading from MediaWiki 1.4 or older, you should upgrade to MediaWiki 1.5 first. If you are upgrading from a Latin-1 wiki, use upgrade1_5.php (found in MediaWiki 1.5) to convert the relevant parts of the database to UTF-8 ($wgUseLatin1Manual:$wgUseLatin1 needs to be set to true in your LocalSettings.phpManual:LocalSettings.php for this to work). Next, run update.php, and then set the $wgLegacyEncodingManual:$wgLegacyEncoding option in LocalSettings.php to the encoding previously used by the wiki (e.g. windows-1252). This is basically how Wikipedia and other Wikimedia Foundation sites were upgraded from MediaWiki 1.4 to 1.5 – see the relevant settings file (warning: huge page!) and some related notes at Wikitech. You may need to upgrade to MediaWiki 1.4 before running the upgrade1.5 script. If you want to make a database dump (e.g. MySQL) of your Latin-1 wiki, make sure the type of the old_text field in the textManual:Text table table is mediumblob, not mediumtext, to avoid character encoding issues.

If you are upgrading from MediaWiki 1.5 or newer, you can upgrade in one step, from your old version to the latest stable version. The vast majority of reports, as well as automated testing, indicate that doing it in one step works just fine. If you have trouble believing this, read this mailing list post. However, please note that when you update from old versions, chances that you will encounter PHP errors are bigger than when you upgrade from the version directly previous to the new version. You would have received these errors anyway, also if you had not skipped versions, but if you had each time done each single update. Only will you - when you skipped versions - get them all at the same time. This will make the upgrade more difficult, but do not forget that you did not have the trouble updating to the intermediate versions, which you skipped!

업데이트 전에 백업을 꼭 해야 하나요?[edit]

네(우문현답).

길게 답변하자면, ㄱ)얼마나 데이터를 소중하게 여기는지, ㄴ)얼마나 백업파일을 만드는 것이 어려운지, ㄷ)얼마나 MySQL 유지 및 관리에 자신이 있는지에 달려있습니다.

An upgrade failure may leave your database in an inconsistent state, in between two versions. A PHP or MySQL error might happen during upgrade leaving your database partly upgraded. In such situations it may be possible to somehow fix this problem with much manual work. However, it will be way easier to just put a database backup from before running update.php in place and to continue with that. Otherwise you might have hours of - needless - work.

Recovery is often complex. Volunteers on the support forums are unlikely to be impressed if you neglect to make a backup and then need help to recover from upgrade-related corruption. A better outcome is if you can revert to your backup, and then report the bug against the corresponding MediaWiki project in the upgrade process which caused the corruption.

Can I keep my LocalSettings.php?[edit]

Yes, but you may have to make some minor changes. The format of LocalSettings.phpManual:LocalSettings.php is largely backwards compatible. Changes which break LocalSettings.php compatibility will be documented in the "configuration changes" section of the release notes.

업데이트 중에 위키에 접속가능 한가요?[edit]

일반적으로 가능합니다. 다만 Git이 (수초간) 임시적으로 연결을 끊을 수 있습니다.

미디어위키의 마이너 버전 상에 업그레이드를 할 경우는, 소스 파일만 새 버전으로 교체하면 됩니다.

Note: the following assumes you have command line access. If you are upgrading between major releases of MediaWiki, the preferred procedure is as follows:

  1. Unpack the new version of MediaWiki into a new directory
  2. Prepare that new directory: copy your current LocalSettings.php from the old directory, copy any installed extensions and custom skins (if any). Check $wgLogo setting in LocalSettings.php and if necessary copy logo file from the old directory to the new directory.
  3. In the release notes for the new version, see if any changes need to be made to LocalSettings.php.
  4. Place the database in read-only mode by inserting the following variable into LocalSettings.php in the old directory - users will see this message if they attempt an edit during the upgrade process:
    $wgReadOnlyManual:$wgReadOnly = 'Upgrading to MediaWiki 1.29.0';
    • This no longer works since MediaWiki 1.27, which also prevents running the update script. See task T151833.
  5. Run the update script or the web updater in the new directory.
  6. Copy the images from the images sub-directory from the old directory to the new directory.
  7. Swap the old directory and the new directory.

업그레이드는 왜 할까요?[edit]

:새 배포 소식을 받아보려면 mediawiki-announce를 구독하시오.

왜냐하면 대개 너무나 쉽고, 최신 버전으로 올리는데 한 단계만 거치며 되는데, 심지어 웹 상에서 할 수 있기 때문입니다. Because it's usually easy enough, a single step from your version to latest and also via web.

Recent releases receive security fixes to keep your wiki and your host safe from vandals, while old releases don't (see Version lifecycleVersion lifecycle). That makes dozens good reasons to upgrade!

New major releases come with new features, which you might want to use: see the release notes for details. In case you need additional arguments to convince your bosses to let you upgrade from a pretty old version, here is a summary:

See also the list of the most voted fixed issues on 버그질라Bugzilla up to 2014.

Also, in MediaWiki 1.18 we started bundling some vital extensions, like a better editor and anti-vandalism tools ConfirmEdit and Nuke; more have been added in later releases.
