ElasticSearch最佳入门实践（六十）创建、修改以及删除索引

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 ... },
        ...
    }
}

示例

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
需要修改配置文件
elasticsearch.yml
action.destructive_requires_name: true
