如何绑定别名

创建索引

kibana 里执行

PUT goods-2020-01-01
{"settings": {"analysis": {"analyzer": {"ik_syno_max": {"type": "custom","tokenizer": "ik_max_word","filter": ["local_synonym_filter","jt_tfr"],"char_filter": ["jt_cfr"]},"ik_syno_smart": {"type": "custom","tokenizer": "ik_smart","filter": ["local_synonym_filter"]},"english": {"tokenizer": "standard","filter": ["english_possessive_stemmer","lowercase","english_stop","english_keywords","english_stemmer"]}},"filter": {"jt_tfr": {"type": "stop","stopwords": [" "]},"local_synonym_filter": {"type": "synonym","synonyms_path": "analysis/synonyms.txt"},"english_stop": {"type": "stop","stopwords": "_english_"},"english_keywords": {"type": "keyword_marker","keywords": ["example"]},"english_stemmer": {"type": "stemmer","language": "english"},"english_possessive_stemmer": {"type": "stemmer","language": "possessive_english"}},"char_filter": {"jt_cfr": {"type": "mapping","mappings": ["| => \\|"]}},"normalizer": {"my_normalizer": {"type": "custom","char_filter": [],"filter": ["lowercase", "asciifolding"]}}}},"mappings": {"dynamic": true,"properties": {"sku": {"type": "keyword","normalizer": "my_normalizer"},"name": {"type": "text"},"gmtCreate":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true},"gmtModified":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true},"makeTime":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true}}}
}

关联别名（创建别名）

kibana 里执行

POST /_aliases
{"actions": [{"add": {"alias": "goods","index": "goods-2020-01-01"}}]
}

删除别名

kibana 里执行

POST /_aliases
{"actions" : [{ "remove" : { "index" : "goods-2020-01-01", "alias" : "goods" } }]
}

查看别名下所有索引

kibana 里执行

GET goods/_alias

查看索引是否有别名

kibana 里执行

GET goods-2020-01-01/_alias

查看词库分词情况

kibana 里执行

POST goods-2020-01-01/_analyze
{"analyzer": "ik_syno_smart","text": "牛栏"
}

查看原索引

kibana 里执行

GET goods-2020-01-01/_mapping
结果
{"goods-2020-01-01" : {"mappings" : {"properties" : {"sku" : {"type": "keyword","normalizer": "my_normalizer"},"title" : {"type" : "text"},"gmtCreate":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true},"gmtModified":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true},"makeTime":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true}}}}
}

更改步骤

1.创建新索引

kibana 里执行

PUT goods-2020-12-21
{"settings": {"analysis": {"analyzer": {"ik_syno_max": {"type": "custom","tokenizer": "ik_max_word","filter": ["local_synonym_filter","jt_tfr"],"char_filter": ["jt_cfr"]},"ik_syno_smart": {"type": "custom","tokenizer": "ik_smart","filter": ["local_synonym_filter"]},"english": {"tokenizer": "standard","filter": ["english_possessive_stemmer","lowercase","english_stop","english_keywords","english_stemmer"]}},"filter": {"jt_tfr": {"type": "stop","stopwords": [" "]},"local_synonym_filter": {"type": "synonym","synonyms_path": "analysis/synonyms.txt"},"english_stop": {"type": "stop","stopwords": "_english_"},"english_keywords": {"type": "keyword_marker","keywords": ["example"]},"english_stemmer": {"type": "stemmer","language": "english"},"english_possessive_stemmer": {"type": "stemmer","language": "possessive_english"}},"char_filter": {"jt_cfr": {"type": "mapping","mappings": ["| => \\|"]}},"normalizer": {"my_normalizer": {"type": "custom","char_filter": [],"filter": ["lowercase", "asciifolding"]}}}},"mappings": {"dynamic": true,"properties": {"sku": {"type": "keyword","normalizer": "my_normalizer"},"name": {"type": "text","analyzer": "ik_syno_max","search_analyzer": "ik_syno_smart","fields": {"cn": {"type": "text","analyzer": "ik_syno_smart"},"en": {"type": "text","analyzer": "english"}}},"gmtCreate":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true},"gmtModified":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true},"makeTime":{"type":"date","format":"yyyy-MM-dd HH:mm:ss","ignore_malformed":true}}}
}

2.复制数据

kibana 里执行

POST _reindex?wait_for_completion=false
{"source": {"index": "goods-2020-01-01"},"dest": {"index": "goods-2020-12-21"}
}

3. 查看复制进度

kibana 里执行

GET _tasks?detailed=true&actions=goods-2020-12-21

如果数据量很少，那么结果是如下，表示复制完成

{"nodes" : { }
}

4. 把别名与新索引关联

先删除原别名与就索引的关系，然后建立新索引和别名的关系

kibana 里执行

POST /_aliases
{"actions" : [{ "remove" : { "index" : "goods-2020-01-01", "alias" : "goods" } },{ "add" : { "index" : "goods-2020-12-21", "alias" : "goods" } }]
}
