Set up the location

Decide on a location - subdirectory or subdomain. I like subdomains. For, I use

For Dreamhost, use the domains >> manage domains page on the DreamHost control panel. As a standard convention, I put the webdocs in an htdocs directory, so the web panel will look like this:


Install Media Wiki

The easiest way is to use the Dreamhost one-click install on Goodies >> Once-click installs

  • Select "Install new website software - Advanced Mode"
  • Then use the panle to install it. Not that the subdirectory needs to be blank here, since the path for the site selected in manage domains already includes it.


Create the Data Base Manually

At the bottom of this same screen, uncheck "Create a data base for me automatically" and fill in the form. By convention, I use a db name that corresponds to the website and application. Each db gets its own user with a secure password:


Make the final configuration changes

Within a few minutes, the Dreamhost installer robot will send an email like this:

Now just go to:
And use the following settings:
Site name: whatever you'd like!
Contact e-mail: whatever you'd like!
Language: whatever you'd like!
Copyright/license metadata: whatever you'd like!
Sysop account name/password: whatever you'd like!
Shared memory caching: no caching
Database host:
Database name: ahswiki
DB username  : ahswikiuser
DB password  : ********
Database table prefix: we recommend "wiki_" (no quotes!)
Superuser account: "-" (i.e. just leave unchecked)
Click "Install!".
Assuming you have no errors, the next page will say:
"Move the config/LocalSettings.php file into the parent directory"
DO THAT! Use FTP to connect to your site, and move LocalSettings.php
out of the "config" sub-directory and into your main wiki directory.
(If you want you can then remove the "config" directory entirely.)
That's it, you're done! Visit your MediaWiki installation at

Follow those instructions and you'll see a screen showing the install sequence:
