如果你想禁止自动创建索引，你可以通过在 config/elasticsearch.yml 的每个节点下添加下面的配置：

2.0版本

action.auto_create_index: false

创建索引

curl -X PUT "localhost:9200/dev_employee_20181221"

WKQ@WKQ-PC MINGW64 /d/WorkSpaces
$ curl -X PUT "localhost:9200/dev_employee_20181219"
{"acknowledged":true,"shards_acknowledged":true,"index":"dev_employee_20181219"}

删除索引

// 删除一个

curl -X DELETE "localhost:9200/dev_employee_20181221"

// 删除多个

curl -X DELETE "localhost:9200/dev_employee_20181220,dev_employee_20181221"

curl -X DELETE "localhost:9200/dev_employee_*"

// 删除所有

curl -X DELETE "localhost:9200/_all"

curl -X DELETE "localhost:9200/*"

WKQ@WKQ-PC MINGW64 /d/WorkSpaces
$ curl -X DELETE "localhost:9200/dev_employee_20181219"
{"acknowledged":true}

索引设置

number_of_shards

每个索引的主分片数，默认值是 5 。这个配置在索引创建后不能修改。

number_of_replicas

每个主分片的副本数，默认值是 1 。对于活动的索引库，这个配置可以随时修改。

curl -X PUT "localhost:9200/my_temp_index" -H 'Content-Type: application/json' -d'
{
    "settings": {
        "number_of_shards" :   1,
        "number_of_replicas" : 0
    }
}
'

curl -X PUT "localhost:9200/my_temp_index/_settings" -H 'Content-Type: application/json' -d'
{
    "number_of_replicas": 1
}
'

配置分词器

curl -X PUT "localhost:9200/spanish_docs" -H 'Content-Type: application/json' -d'
{
    "settings": {
        "analysis": {
            "analyzer": {

                }
            }
        }
    }
}
'

curl -X GET "localhost:9200/spanish_docs/_analyze?analyzer=es_std" -H 'Content-Type: application/json' -d'

// 创建索引

curl -X PUT "localhost:9200/dev_employee_20181221"

// 给别名添加索引

curl -X PUT "localhost:9200/dev_employee_20181221/_alias/dev_employee"

// 检测这个别名指向哪些索引同一别名多个索引

curl -X GET "localhost:9200/*/_alias/dev_employee"

// 哪些别名指向这个索引一个索引多个别名

curl -X GET "localhost:9200/dev_employee_20181221/_alias/*"

// 切别名

curl -X POST "localhost:9200/_aliases" -H 'Content-Type: application/json' -d'
{
  "actions": [
	  { "remove": { "index": "dev_employee_20181220", "alias": "dev_employee" }},
