Wikibase/Suite/en

Introduction
A Wikibase install often consists of the following elements:


 * An RDBMS (MariaDB/MySQL or SQLite) [required]
 * MediaWiki [required]
 * The Wikibase extension [required]
 * Other related extensions [optional]
 * The Wikidata query service (WDQS) [optional]
 * The WDQS proxy
 * The WDQS frontend
 * QuickStatements [optional]
 * Elasticsearch [optional]

The Docker install contains all these components and can be started with a single  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.

Network configuration
Consult the network description and diagram: https://www.mediawiki.org/wiki/Wikibase/Maintaining#Architecture_overview

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

Instructions
Working MediaWiki nginx config

Optional sidebar
If you'd like to add some Wikibase-related links to your main page sidebar, you can add these configuration stanzas to your LocalSettings.php.

OAuth
Wikibase needs the OAuth extension for the Wikidata query service, as you'll see below.

Installation
The OAuth install instructions are comprehensive. Note that you'll benefit from a working understanding of to finish this install.

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 [ https://archiva.wikimedia.org/repository/releases/org/wikidata/query/rdf/service 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.
 * To configure the query service, consult both the Wikitech WDQS guide and the WDQS user manual.
 * In particular, configure RWstore.properties as noted here:.
 * See also these WDQS Docker image configuration tips.

Overview
Elasticsearch is a Lucene-based search engine. To get it working with MediaWiki/Wikibase, you'll need the following software:


 * Elasticsearch 6.5.4
 * OpenJDK


 * Three MediaWiki extensions:
 * Two Elasticsearch plugins:
 * search-extra
 * search-highlighter
 * Two Elasticsearch plugins:
 * search-extra
 * search-highlighter

Instructions

 * Install Elasticsearch 6.5.4 (refer to its install instructions ).
 * ES's install process will prompt you to install OpenJDK.
 * Install the aforementioned extensions on your MediaWiki instance:
 * Add the following lines to :
 * Add the following lines to :
 * Add the following lines to :
 * Add the following lines to :
 * Install the aforementioned Elasticsearch plugins using these commands:
 * Modify  as needed:
 * Name your cluster with the directive.
 * Make a single-node cluster:
 * Set as needed
 * Modify as needed (above all, set   and   based on the amount of memory available to your host)
 * Note the "flood stage" settings for your disk size.
 * You can either ensure that at least 5% of the disk is available at all times, or you can alter the  setting. For more information, consult this StackOverflow article.
 * Start jobs running in the background:
 * Run  for CirrusSearch:
 * Run ForceSearchIndex (best installed as a cron job):

Instructions

 * Download and install QuickStatements from GitHub.
 * Make changes to config.json as needed. Lines to change include but are not limited to:
 * publicMwOAuthUrl and MwOAuthUrl: set to your Wikibase instance's OAuth URL
 * api:
 * pageBase:
 * toolBase:

For more information, consult the Docker image README.
