Installing MediaWiki on 8-Coral
| Installing MediaWiki 1.17 or 1.18 on 8-Coral Series |
Introduction
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.
Preparation
Download and Extract Mediawiki
- Download MediaWiki 1.17.0.tar.gz (or later version) from here and save it to a known location.
- Open the downloaded file (mediawiki-1.17.0.tar.gz) with 7-Zip. This will show mediawiki-1.17.0.tar
- Extract this to the server root folder UniServer\www, creating mediawiki-1.17.0
- Rename the folder mediawiki-1.17.0 to wiki
Start servers
Run The Uniform Server control menu and start both servers if not already running. Execute "Start_as_program.exe" to start the Unicontoller panel, and then choose "Start Both" from the panel.
Change PHP accelerator to APC
The installation script for MediWiki does not detect eAccelerator, which is The Uniform Server's default PHP acelerator. We will change to APC instead.
- Choose Server Configuration from the Unicontroller panel, and then select PHP.
- From the drop-down panel, select PHP Accelerators APC and eAccelerator.
- Uncheck Enable eAccelerator
- Dismiss the popup notice about the PHP Configuration update.
- Check Enable APC
- Dismiss the popup notice about the PHP Configuration update.
- Close the Server Configuration panel.
- From the Unicontroller panel, choose Stop Apache and wait for the button to change indication.
- Start Apache.
Enable InnoDB for MySQL
MediWiki exhorts installers to enable InnoDB due to some known problems with MyISAM. On the other hand, MyISAM is more portable in the situation that there are multiple applications using the same MySQL server. This is because all of the InnoDB transactions are stored in the same ibdata1 file, whereas each MyISAM db has its own folder.
- Choose Server Configuration from the Unicontroller panel, and then select MySQL.
- From the drop-down panel, select InnoDB Enable/Disable.
- Check Enable InnoDB
- Close the Server Configuration panel.
- From the Unicontroller panel, choose Stop MySQL and wait for the button to change indication.
- Start MySQL.
Create the MySQL database
Before installing MediaWiki you must create a new MySQL database and user.
- From the control menu select: Server configuration > MySQL > Create delete Database
- Enter the database name to create; for example "wikidb" (without the quotes)
- Click the "Create Database" button. You can now close this menu.

Complete!
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/
Portability
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, it will prevent The Uniform Server from running. To resolve this situation, either stop the other program or preferably move The Uniform Server to different ports by moving the servers 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.
More importantly, the above installation is an extreme 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.
