Wikibase/Suite

Introduction
A Wikibase install often consists of the following elements:


 * MediaWiki
 * An RDBMS such as MariaDB
 * The Wikibase extension (and other related extensions)
 * The Wikidata query service (WDQS)
 * The WDQS proxy
 * The WDQS frontend
 * QuickStatements
 * Elasticsearch

The Docker install contains all these components and can be started with a single docker-compose command. This install meets the needs of many Wikibase users, especially those just starting out.

However, for those not wanting to run Docker (because of additional administrative overhead, scaling issues in production, or a desire to understand the components better), here's how to install each component manually.

Before you dive in
There's a large amount of technical documentation to be read and enjoyed at the Wikibase technical doc site.

To successfully navigate this process, you should probably have:


 * Familiarity with Linux and web server software
 * One or more servers on which you have permissions to install software

Instructions
The Mediawiki install linked in the next step relies on a running RDBMS with a database and user already created.

We recommend using MariaDB, and though a full installation guide is outside of the scope of this document, start with this excellent collection of documentation and this tutorial.
 * Create a database
 * User account management

Wikidata Query Service
The Wikidata Query Service (WDQS), which consists of the Blazegraph SPARQL query backend and its updater, can be and often is used in conjunction with Wikibase.

Instructions
While intrepid users may wish to compile their own instance of WDQS, we recommend using the precompiled version.


 * Download the desired version from Archiva.
 * 0.3.42 is the recommended version as of this writing, September 2020. However, expect this information to be updated with the impending Mediawiki release.
 * Consult the WDQS user manual.
 * In particular, configure RWstore.properties as noted here.
 * See also these WDQS Docker image configuration tips.

Instructions

 * Install Elasticsearch 6.5.4 using these install instructions.
 * This will prompt you to install OpenJDK.
 * Install the extensions CirrusSearch and Elastica on your MediaWiki instance.
 * Modify elasticsearch.yml as needed
 * Name your cluster with the cluster.name directive
 * Make a single-node cluster: "discovery.zen.minimum_master_nodes: 1"
 * Set network.host as needed
 * Modify jvm.options as needed (above all set "-Xms" and "-Xmx" based on the amount of memory available to your host)
