Note: This documentation is for Tiki, version 1.8. It probably works for earlier versions, but I haven't tested it. For Tiki version 1.9 and later there is a different approach that requires editing db/tiki-db.php and using some new features in tiki-install.php. The newer variant is scantily documented in the following pages (at MultiTiki 1.9).

Multiple Tikis on a Single Server

It is possible to have multiple Tikis on a single server. There are three major requirements that must be satisfied:

• Tiki must have an access to a separate database for each URL.
• Apache must know how to associate multiple URLs with the Tiki.
• You must create the necessary directories with the Tiki's main directory.

Create a separate database for each url.

• Each database will have a different name. In mysql, creating the databases is normally accomplished with the mysqladmin command. You may have permission to create the database, or you may have to ask a system administrator. To actually tell Tiki which database goes with which URL you have to edit one of Tiki's PHP files. The file db/local.php is designed for this purpose.

Configure Apache for multiple Tikis.

• Typically, each Tiki will be accessed by a separate URL through Apache. Generally, the URLs are specified as virtual hosts — often in VirtualHost stanzas within Apache's configuration file. Remember to restart Apache after you have changed the configuration files. On Linux this is usually best done with the "apachectl" graceful command.
• On shared hosting, you can use "parked a domain" to have extra domains pointing to the same TikiWiki installation.

Create the necessary directories within Tiki's main directory.

• On a Unix system, the easiest way to create the new directories and set permissions is by specifing more than one tikidomain when you run setup.sh. You would run setup.sh with a command like:

./setup.sh apache apache 02755 domain1 domain2 domain3

Create the directories manually for Windows hosting.

It is possible to add additional tikis after you have installed a single Tiki. However, with the execption of the case in the following paragraph, you will have to manually create the needed directories. If you are hosting on a Unix system, you will also need to manually set the ownership and permissions.

http://tikiwiki.org/tiki-index.php?page=RecipeMultiTiki has a detailed recipe tested under ))RedHat((, version 8 and version 9 and Yellow Dog Linux, version 3.0. Root access to the Linux machine is required for this approach. If you follow the instructions exactly, there is a Python script you can use to add additional Tikis later.

There are a few minor problems that crop up with this approach. The admins for the various tikis have the ability to overwrite each others changes to the css. Ordinary. users with the same login names on different tikis would also be able to overwrite each other's changes to css files. Finally, you must use Apache's mod_rewrite if you want the different Tikis to have their own favicons.
