MediaWikiにCirrusSearch導入

https://gyazo.com/f4a9545ef56379a650976008b24ba643

動機

全文検索で確実に結果が出るようにしたい

Wikipediaでも使われているすごい検索

ElacsticSearchを使っている

インストール

意外と手順が多いし飛ばすとハマる

日本語情報少なすぎ

# yum -y install java-1.8.0-openjdk-devel

これがないとElasticSearchが入らない

analysis-kuromojiも入れる

起動して動作確認

しばらくはサーバが重いかも

バージョンページを開いてエラーがないのを確認

5. インデックスを作成する

Only Elasticsearch 5.x is supported. Your version: 6.5.4.

おい

ElasticSearch6.x入れてしまった時の対処

# vi /etc/yum.repos.d/elasticsearch.repo

# yum downgrade elasticsearch-5.6.14-1.noarch

# /usr/share/elasticsearch/bin/elasticsearch-plugin remove analysis-kuromoji

# /usr/share/elasticsearch/bin/elasticsearch-plugin install analysis-kuromoji

# sudo systemctl restart elasticsearch

# sudo systemctl daemon-reload

Add this to LocalSettings.php:

wfLoadExtension( 'Elastica' );

require_once( "$IP/extensions/CirrusSearch/CirrusSearch.php" );

$wgDisableSearchUpdate = true;

Configure your search servers in LocalSettings.php if you aren't running Elasticsearch on localhost:

There are other $wgCirrusSearch variables that you might want to change from their defaults.

Now run this script to generate your elasticsearch index:

php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/updateSearchIndexConfig.php

Now remove $wgDisableSearchUpdate = true from LocalSettings.php. Updates should start heading to Elasticsearch.

Next bootstrap the search index by running:

php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/forceSearchIndex.php --skipLinks --indexOnSkip

php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/forceSearchIndex.php --skipParse

Note that this can take some time. For large wikis read "Bootstrapping large wikis" below.

Once that is complete add this to LocalSettings.php to funnel queries to ElasticSearch:

$wgSearchType = 'CirrusSearch';
