One public and non-trivial example of wiki farm configuration is the configuration system used for the Wikimedia production and beta wiki farms [0]. The heart of this system is MWMultiVersion [1] and the configuration files [2] that populate and use a SiteConfiguration [3] object that chooses different settings based on the information provided by MWMultiVersion. Besides the public configuration data shown in the git repository [0] there are private settings [4] which are only committed locally on the deployment server and distributed from there to all of the MediaWiki servers. This system is pretty complicated and likely to be overkill the majority of wiki farms, but it does show some techniques for managing complex configuration. A much more simple solution could be just to replace LocalSettings.php's contents with an include of common settings and conditional include of environment specific settings that you keep in separate files (e.g. LocalSettings.dev.php).
