1、创建索引

命令如下

  from elasticsearch import Elasticsearch
    es = Elasticsearch([{"host":"10.87.6.3","port":9200},])

    s = "test" + "python"
    try:
        ret = es.indices.create(index=s)
    except Exception as e:
        print(e)
    else:
        print("创建成果")
        print(ret)

 

返回的结果如下，证明创建成果

{‘acknowledged‘: True, ‘shards_acknowledged‘: True, ‘index‘: ‘testpython‘}

 

返回的结果如下，证明创建失败

RequestError(400, ‘resource_already_exists_exception‘, ‘index [testpython/yEzYUZEiTjaZWxtN0RM_Uw] already exists‘)

 

 

2、删除索引

代码如下

    try:
        ret = es.indices.delete(index=s)
    except Exception as e:
        print(e)
    else:
        print("删除成果")
        print(ret)

 

返回结果，证明删除成果

{‘acknowledged‘: True}

 

返回结果，证明删除失败

NotFoundError(404, ‘index_not_found_exception‘, ‘no such index‘)
