Here's what I'm running:
MediaWiki 1.33.0
PHP 7.2.19-0ubuntu0.18.04.2 (apache2handler)
MySQL 5.7.27-0ubuntu0.18.04.1
I have followed the steps on the extension page:
- Installed Elasticsearch 6.5.4 per the instructions for MediaWiki 1.33.0.
- Installed Elastica, shows up on Special:Version
- Installed CirrusSearch, causes Special:Version to not load after inserting require_once "$IP/extensions/CirrusSearch/CirrusSearch.php"; in LocalSettings.php
The following error is displayed on Special:Version:
[6615ca91ab54427a72fcf3c5] 2019-08-20 14:52:28: Fatal exception of type "Error"
When I attempt to run the first step of the CirrusSearch instructions, this happens:
hincb@cbwiki2:/var/www/html/mediawiki$ php extensions/CirrusSearch/maintenance/updateSearchIndexConfig.php

Here's verification of my ElasticSearch version:
hincb@cbwiki2:/var/www/html/mediawiki$ curl -X GET "localhost:9200/?pretty"
{
"name" : "Og7QKNt",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "geDUNZn5Tk63F6wjWs8Smg",
"version" : {
"number" : "6.5.4",
"build_flavor" : "default",
"build_type" : "deb",
"build_hash" : "d2ef93d",
"build_date" : "2018-12-17T21:17:40.758843Z",
"build_snapshot" : false,
"lucene_version" : "7.5.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
Any ideas why this isn't working? I appear to have the correct versions of everything installed. I've previously configured ElasticSearch 5.4.3 on MediaWiki 1.30.0 and didn't have any issues at all so I generally know what I'm doing until I start getting errors like this. Thanks.
