 Data Recovery

On 2017-04-04 we had a rather major disk malfunction that caused data loss. The data on this site was originally restored from a 2016-11-05 backup, but with wiki pages changes since then recreated from the search index.

Note that files and images uploaded since November are still missing and will need to be re-uploaded and reattached to the pages by hand.

Please let us know if you find anything else missing or broken due to this outage. We thank you for your patience.

Multiple Tikis on a Single Server

MultiTiki



Or how to set up multiple Tikis on the same server with a single Tiki file set installation. For managing different Tiki installations (several copies of the same installation files) in the same or different servers, see TRIM instead.

It is possible to have multiple Tikis on a single server and using a single copy of the installation file set. This can be done through:
  1. Multitiki using domains: using different domain names (i.e. http://site1.org/, http://site2.org/, ...). or
  2. Multitiki using subdirectories: having your several tikis in subdirectories of the same domain (i.e. http://yourhost/site1/, http://yourhost/site2/, ...) .

There are some differences depending on the previous option, but there are three major requirements that must be satisfied in both cases:
  • 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.

1. 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.

See an example of edited local.php file for multikis (either 'multitiki using domains' or 'multitiki using subdirectories') at Manual Installation.

2. Configure the server to host multiple Tikis

2.1. Multitiki using domains

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.

2.2. Multitiki using subdirectories

Add symlinks. See the instructions in Manual installation AND in MultiTiki Manual Installation for the time being (and/or improve this page).

3. 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:


Run setup.sh from the console, and follow instructions. You'll need to grant execution permission on that file the first time, as user with root privileges:
% chmod +x ./setup.sh


Then, just run it with no parameters in the command line, and it will start in interactive mode:
% ./setup.sh


From there follow instructions. Some of the options are explained below:
  • Group: Defaults to nobody or www-data or others (depending on the system, whatever the script will suggesst you as default) but may also be the standard group for the files as uploaded.
  • Multi: You should add here the names of your multitiki sites, separated by spaces (i.e. "site1 site2", or "www.site1.org www.site2.org", without the quotation marks. The script will create as many subdirectories as appropriate using this name for each tiki site under this multitiki installation.


If it doesn't work for any reason, you can do its job by hand. See Manual Installation if needed.


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.

4. Optionally, add .htaccess with rewrite rules

You optionally add some Apache Clean URLs for your tikis.


5. Sys admin tasks from the Console

Since Tiki11, you can rebuild the Search Index and many other sys admin tasks from the command line also for Multitiki setups. And Since Tiki12.3, you can also handle the Mail Queue and the Daily Reports. You can use commands like:

root@server:/path/trunk# php console.php index:rebuild --site=site1.example.com  
root@server:/path/trunk# php console.php index:rebuild --site=site2.example.com  
...


See Console
