======Multisite deployment====== >>Requires 1.1.6.6 (or backport of ""BuildFullpathFromMultipath()"" feature) Still under development, this modification is mostly untested. Please report any bugs you observe. ---- To-do: ~-Take care of any file access being redirected to local config tree if neccessary ====Demonstration==== Those three sites share the same code: ~-http://wikka.larp-bb.de ~-http://www.larp-bb.de ~-http://gionew.larp-bb.de (extended by a lot of custom actions and stuff, it's basically the same as http://gio.larp-bb.de, even working on the same database) >> =====Specifications===== Multisite deployment shall enable a single installation of Wikka to provide service to multiple sites. By doing this, each site should keep its own configurability, e.g. own plugins folders, stylesheet and local wikka.config.php.::c:: =====Installation===== In wikka.php right after %%(php) $wakkaConfig = array_merge($wakkaDefaultConfig, $wakkaConfig); // merge defaults with config from file %% insert %%(php) // multi site configuration $multiDefaultConfig = array( 'local_config' => 'wikka.config' # path to local configs ); $multiConfig = array(); /** * To activate multisite deployment capabilities, just create an empty file multi.config.php in * your Wikkawiki installation directory.

Corresponding to this for it to work without multisite stuff, in ##wikka.php## change %%(php) 'stylesheet' => 'wikka.css', %% to %%(php) 'stylesheet' => 'css/wikka.css', %% =====Usage===== To activate multisite deployment capabilities, just create an empty file ##multi.config.php## in your Wikkawiki installation directory. This file can contain an array definition for $multiConfig. Relevant keys in the array are a global directory for local settings 'local_config' and designated directories for different host requests, e.g. you may want http://example.com and http://www.example.com using the same local config tree: %%(php) 'http_www_example_com' => 'http.example.com' 'http_example_com' => 'http.example.com' %% An admin can decide to put a specific local config in a more readable and shorter directory. The $configkey is created as 'protocol_thirdleveldomain_secondleveldomain_topleveldomain'. Subdirectories are not supported at the moment, but should be easy to implement. If no designated directory is found in multi.config.php, the script uses the $configkey value and replaces all underscore by dots: ~-protocol.thirdleveldomain.secondleveldomain.topleveldomain ~-http.www.example.com As each site may differ in its configuration and capabilities, we should consider using plugin directories below the $configpath. Effectively, this replaces the 1.1.6.6 plugins folder. It goes even a little bit further by providing a site specific upload directory. This is accomplished by adding the local config path to some $wakkaConfig array elements: action_path, handler_path, wikka_formatter_path, wikka_highlighters_path, wikka_template_path, upload_path. No need to change 3rdparty stuff as anything in there would need support by an action, handler or formatter. Currently, the ##.htaccess## of the Wikkawiki installation directory is valid for all sites served by this setup. That means it isn't possible to disable mod_rewrite for just some of the sites while having it enabled for others. ::c::---- CategoryUserContributions
