Summary
For experienced users, here is the quick version of the installation instructions. Most users (like if you don't know how to install or check for the prerequisite software on your computer) will want to links>#Main-installation-guide|follow the main installation guide.

  Check that your system meets the following minimum requirements. ( See installreq>Special:MyLanguage/Manual:Installation requirements|Installation requirements for more details. Make sure to also check the releasenotes>Special:MyLanguage/Release notes|RELEASE NOTES shipped with MediaWiki for requirements. ) You'll need:

 * A web server such as Apache or IIS
 * Local or command line access is needed for running maintenance scripts

If you install locally and later want to access your wiki from domain, then you will need to change LocalSettings.php from  to domain.

Alternatives to manual installation
If your head is swimming from reading the above &mdash; or you feel frustrated, stuck, or lost &mdash; this section is for you...

You can avoid manual installation by using a pre-integrated MediaWiki appliances>Special:MyLanguage/Software appliances</>|software appliance, host-serv>Special:MyLanguage/Hosting services</>|hosting services with 1-click installation, or wiki farms.

If you are installing for hacker>Special:MyLanguage/How to become a MediaWiki hacker</>|development or testing, consider using vagrant>Special:MyLanguage/MediaWiki-Vagrant</>|MediaWiki-Vagrant, a set of configuration scripts for Vagrant that automate the creation and update of a virtual machine that runs MediaWiki and your choice of extensions and services.

Official docker images are released on [<tvar|1>https://hub.docker.com/_/mediawiki</> Docker Hub].

You can also use community resources based on platforms such as [<tvar|url>https://github.com/rlewkowicz/docker-mediawiki-stack</> Docker].

This is managed by Jenkins and should be kept up-to-date for some time.

These are community based resources and should always be treated with some measure of caution. Use at your own risk.

Wiki families (multiple wikis)

 *  Main page: 

A wiki family is more than one wiki installed on the same computer.

Installing MediaWiki more than once
One approach is to install multiple instances of MediaWiki (such as with a 1>Special:MyLanguage/Software bundles#MediaWiki pre-integrated with AMP packages</>|software bundle like the Bitnami MediaWiki Stack) in different directories – one for each wiki.

For example, you want an enterprise wiki and a personal wiki, and you want to keep them totally separate.

Multiple wikis with one MediaWiki
You could use a single installation of MediaWiki for multiple wikis, by either:


 * 1) Using a different database for each wiki.  See <tvar|1></>. 


 * 1) Using a different database prefix for each wiki.  See <tvar|1></>. 

Installing an existing wiki
Some users wish to install MediaWiki with Wikipedia, Wiktionary, or some other wiki loaded. This is useful for reading offline, for conducting experiments, and for mirroring/forking.

The main (but not necessarily the easiest) method for doing this is to install MediaWiki and then import. '' See 1>Special:MyLanguage/Manual:FAQ#Wiki importing</>|Manual:FAQ#Wiki importing. ''

(Non-MediaWiki solutions, such as Xowa and Kiwix, can be found at w:Wikipedia:Database download, and are probably the best options).
