es手动创建索引,修改索引,删除索引

1、创建索引

创建索引的语法
PUT /my_index
{
  "settings": { ... any settings ... },
  "mappings": {
    "type_one": { ... any mappings ... },
    "type_two": { ... any mappings ... },
    ...
  }
}

创建索引的示例
PUT /my_index
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  },
  "mappings": {
    "my_type": {
      "properties": {
        "my_field": {
          "type": "text"
        }
      }
    }
  }
}

2、修改索引
PUT /my_index/_settings
{
  "number_of_replicas": 1
}

3、删除索引
DELETE /my_index
DELETE /index_one,index_two
DELETE /index_*
DELETE /_all

可以设置下面的属性,使DELETE /_all 失效,必须指定索引名称,才可以删除。



elasticsearch.yml
action.destructive_requires_name: true
