我想加载一个 XML 维基百科转储，例如: http://ftp.acc.umu.se/mirror/wikimedia.org/dumps/enwiki/20171001/enwiki-20171001-pages-articles.xml.bz2 进入 Elasticsearch (5.6.4)。 但是，我找到的所有工具和教程都已过时，并且与我的 Elasticsearch 版本不兼容。 谁能解释将转储导入 Elasticsearch 的最佳方法是什么？

最佳答案

两年前，维基媒体提供了生产 Elasticsearch 索引的可用转储。

索引每周导出一次，每个 wiki 有两次导出。

The content index, which contains only article pages, called content;
The general index, containing all pages. This includes talk pages, templates, etc, called general;

你可以在这里找到它们 http://dumps.wikimedia.org/other/cirrussearch/current/

• 根据您的需要创建映射。例如:

  {
       "mappings": {
       "page": {
          "properties": {
             "auxiliary_text": {

             },
             "category": {
                "type": "text"
             },

                         }
                      }
                   },

             }
          }
       }
    }
  

创建索引后，只需键入:

zcat enwiki-current-cirrussearch-general.json.gz | parallel --pipe -L 2 -N 2000 -j3 'curl -s http://localhost:9200/enwiki/_bulk --data-binary @- > /dev/null'

尽情享受吧!
