How to Get MediaWiki
The software is a free and open source. It is developed and patched by a large number of volunteers and a small team of development staff and continues to be updated and improved.
Due to MediaWiki's popularity, almost all web providers offer it as an optional install through their control panels.
How to Install MediaWiki
There are plenty of installation guides online, including official resources.
You can also install MediaWiki using a package manager, such as apt-get on Debian/Ubuntu systems. MediaWiki works best on Unix/Linux servers.
MediaWiki Installation Requirements
You'll need several components to install MediaWiki:
Handles requests from users
Stores article data
PHP Version 5.5.9 or later
Processes user requests, displays pages
Database Size Limitations
MediaWiki should cope with small and large databases alike, but it will be limited by the type of hosting account you have, should it begin to tax the server.
You will need sufficient resources to cope with the traffic you're getting, and you may need to liaise with your host if you exceed reasonable limits.
MediaWiki Server Requirements
You'll need 5 additional components to use MediaWiki:
- A compatible web server
- PHP 5.5.9 or later
- MySQL, PostgreSQL, SQLite, or MariaDB databases
- 256 MB of RAM
- 85 MB of storage
- Optional dependencies
The purpose of the web server is to serve the requested pages to the client browser. It is one of the key requirements and necessary for the Mediawiki service to function. This is usually provided by your hosting provider.
This is the programming language in which MediaWiki is written, and is required in order to run the software.
PHP version 5.5.9 or later is required for the latest stable version of MediaWiki.
MySQL, PostgreSQL, SQLite, or MariaDB databases
MediaWiki stores all the text and data in a database, which is then shared with other web-based applications. You will need one of the following database servers to run the latest version of MediaWiki: MySQL, PostgreSQL, SQLite, or MariaDB.
RAM and Storage
It is recommended to use 256MB of RAM 85MB of storage for a single computer Media Wiki installation.
However, it should be noted that this may not be enough for a busy public site. Some users have reported running MediaWiki on as little as 48MB of RAM according to the official MediaWiki website.
Additional functionality such as image thumbnailing and email sending can be added using a range of additional optional dependencies.
These dependencies, including SendMail, ImageMagick, and Shell Access are not essential for MediaWiki installation.
Additional Requirement information
Even the cheapest shared plans will exceed the minimum system requirements, but a well-trafficked wiki will tax a server quickly. Even better is a hosting provider that will install MediaWiki for you.
This will save you a lot of time. Your host will also keep up with the latest updates, which is important for security.
Who Uses Mediawiki?
Aside from Wikipedia, MediaWiki has been used for other projects developed under the Wikimedia brand, including Wiktionary. It supports specialized content, such as mathematical formulae, hieroglyphs, and media galleries, making it suitable for practically any purpose. Thousands of other users run their own wikis on the web, on internal intranets, and in schools.
Communities Using Mediawiki
Perhaps the most fun of them all, a wiki community for gamers!
Communities have sprung up to host wikis outside of the Wikimedia network sites. There are some niche hosts that specializing in hosting wikis for specific subjects, such as Gamepedia for - you guessed it - gaming, and Biowikifarm for biology.
Permissions can be granted to users or groups, and users can automatically be added to a group when their behavior fits a particular pattern.
For example, a user that edits articles frequently could be promoted to a group with more rights than a casual editor. Admin users have ultimate permissions, including the ability to change the way the wiki software looks.
Wiki Size Suitability
Despite powering large wikis, MediaWiki is perfectly fine for wikis on smaller shared hosting accounts with a small community of users.

MediaWiki uses a particular type of markup, known as MediaWiki syntax. This is different from HTML code, yet follows similar conventions.
It's designed to be easy to use for non-technical editors and was designed specifically to be readable.
Despite this, users will almost certainly need a cheat sheet to create formatting and insert images.
There's also a toolbar that makes it much easier to quickly format text without typing the syntax by hand. A visual editor is also available for WYSIWYG editing.
Link Usage in MediaWiki
Links are the primary method of navigation, and MediaWiki automatically detects broken links so that users are prompted to fill in blanks and expand the content.
Users can also put their topics into categories and subpages, and there's a search box to find articles fast.
MediaWiki also has sophisticated tools that make it easier to control edits in real-time. If two users go into a topic and edit it, MediaWiki recognizes the potential clash and tries to combine the edits into one.
The application audits edits and lets users review them and potentially reverse them. Users can flag particular topics as 'watched' to keep a close eye on edits performed by others.
MediaWiki Plugins Library
Like many PHP applications and scripts, MediaWiki's flexibility is enhanced by its plugin library, which currently contains more than 2,000 different extensions.
These extensions add new features or change the functionality of the core application. Users can write their own.
Installing MediaWiki via CMS
Many web hosts offer MediaWiki as one of the CMS packages that can be installed. The best option is to use their version if it's available through your host's control panel.
The initial configuration of MediaWiki is through a form that the administrator navigates to after unpacking the MediaWiki files. You just put in the information that MediaWiki needs to run, such as the database location and the username and password.
Configuration via LocalSettings.php
You also perform other configuration through a configuration file, LocalSettings.php. You can download this file via FTP, edit it on your computer, and then upload back to the server.
SSH access is useful if you're comfortable using the command line. This way, you can edit the file directly when you need to make changes, such as pointing MediaWiki at a new database or installing a custom theme.
Editing this file is straightforward. It's in PHP, but you don't have to have extensive knowledge of the language. It's just a list of variables that are mostly self-explanatory. You just change the values you want to change and save it.
MediaWiki also has hundreds of options in its settings pages and has been translated into more than 300 languages. Its appearance can be controlled with CSS and scripting. All edits to the themes are carried out within the wiki software, although the permissions should be locked down to admin users only.
Note: in MediaWiki, templates do not refer to the appearance of the page layouts. Templates are snippets of content that can be planted into pages and automatically displayed.
My Top 3 MediaWiki Hosts
It's time to take a look at my favorite hosts offering an easy way of utilizing MediaWiki.
These include easy-installs and ready to go versions of MediaWiki itself.
MediaWiki with Siteground.
You'll want a hosting provider that gives you room to grow as more users add pages to your wiki.
This company is an example of a hosting provider that doesn't specialize in MediaWiki but makes it easy to host MediaWiki sites.
SiteGround is the one we recommend.
They also have unlimited MySQL databases for MediaWiki projects.
Even better, the company offers MediaWiki pre-installed.
SiteGround can also migrate wikis from a pre-existing installation to the new server.
MediaWiki with Bluehost.
Bluehost is another MediaWiki-friendly web host.
The company offers shared, cloud, or dedicated servers. Like SiteGround, it offers SSH access, across its service tiers.
While it also offers one-click installs, MediaWiki didn't seem to be mentioned.
That's not a dealbreaker, as it's easy to install MediaWiki on your own.
MediaWiki with Hostgator.
Even cheaper is HostGator, starting at $2.43 a month.
As with SiteGround, HostGator can migrate an existing wiki hosted elsewhere.
Similar to Bluehost, the company doesn't have a dedicated MediaWiki plan.
MediaWiki is a one-click install over Bluehost's regular hosting.
The lowest tier includes a single domain and one-click install and unmetered bandwidth. HostGator is good for people new to hosting wikis.
Points to Remember
All of the major web hosting providers support these, with many of them making it easier to get started with MediaWiki by setting up the prerequisites and even installing MediaWiki for you.
Be aware that many of the cheaper plans are on shared hosting servers, where your wiki shares a server with other websites. If your wiki gets a lot of users making edits, you'll want to move to a VPS.
Pros and Cons
In the meantime, let's sum up a few ups and downs of MediaWiki, which are noteworthy.
- Popular wiki with the large user base.
- Lots of extensions available.
- Free and open source.
- Can be difficult to configure.
- Requires configuration through a text file.
- Changes in the web server, PHP, or database can break the wiki.
