测试环境单节点启动ElasticSearch

1	nohup docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:5.4.1 &

创建索引(默认情况下，创建的索引分片数量是 5 个，副本数量是 1 个。)

测试环境：PUT http://192.168.130.19:9200/seqbank/

正式环境：PUT http://192.168.130.21:9200/nucbank/

{
    "settings": {
		"number_of_shards": 30,
		"number_of_replicas": 1
	}
}

更新索引字段（以create_date举例）

{
  "properties": {
    "create_date": {
      "type": "date",
      "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
    }
  }
}

创建mapping

测试环境：

PUT http://192.168.130.19:9200/seqbank/_mapping/nucleotide

正式环境：

PUT http://192.168.130.21:9200/nucbank/_mapping/nucleotide
