Installing MediaWiki 1.18 on 8-Coral Series


This guide shows how to install MediaWiki on The Uniform Server 8-Coral Series. We will follow MediaWiki's recommendation and use 7-Zip to extract the files, since Windows cannot do this.

  • 7-Zip's download site: [1]
  • Download the latest version and install it.

Download and Extract Mediawiki

  1. Download MediaWiki 1.18.0.tar.gz (or later version) from here and save it to a known location.
  2. Open the downloaded file (mediawiki-1.18.0.tar.gz) with 7-Zip. This will show mediawiki-1.18.0.tar
  3. Extract this to the server root folder UniServer\www, creating mediawiki-1.18.0
  4. Rename the folder mediawiki-1.18.0 to wiki

Start servers

Execute UniServer\Start_as_program.exe to start the Unicontoller panel, and then choose "Start Both" from the panel.

Create the MySQL database and user

Before installing MediaWiki you must create a new MySQL database and user.

  1. From the Unicontroller, select: Server Configuration > MySQL > Create delete Database .
  2. Enter the database name to create; for example wikidb.
  3. Click the "Create Database" button. You can now close this menu.
  4. From the Server Configuration, select: MySQL > Create Restricted MySQL User .
  5. Enter the user name (example: WikiDBU).
  6. Enter password (example: Yusr0936).
  7. Enter the database wikidb (as created above).
  8. Leave all permissions marked and click the "Create User" button. Close this menu.

This last installation page triggers off a download of LocalSettings.php, which is the static, non-database portion of the configuration. This must be saved to folder *\UniServer\www\wiki.

You can now access your wiki by clicking the "enter your wiki" link on the "Complete!" page, or by typing the following into your browser address bar: http://localhost/wiki/


If you want a portable version of MediaWiki, copy the folder UniServer and all its content to your USB memory stick. Don’t expect fantastic speeds, but it is usable.

The Uniform Server uses the standard ports (Apache port 80 and MySQL port 3306). If a host PC is currently running another program on these ports, this will prevent The Uniform Server from running. To resolve this situation, either stop the other program or better yet move The Uniform Server to different ports by using the MultiServers button.

MySQL Security

This installation guide is intended to get the application up and running purely for testing. The configuration options should be reviewed if you are intending to put the application online. Be sure to read any security advice from MediaWiki and check their web site. Specifically, you may be interested in reading MediaWiki's Manual:Security articles.

More importantly, the above installation is a security risk if put online as is. It is imperative that you secure the MySQL server before putting your servers online. Please read MySQL Security and restrict the privileges for any user who has connection access to your server.

Among other things, be sure you created a restricted MySQL user limited only to the MediaWiki database. If you used "root" to do the installation, be sure to substitute the restricted user and password for "root" in the LocalSettings.php file.
