ElasticSearch 集群的索引别名管理

一、索引别名

（一）添加索引别名

1.给单个索引添加别名

POST http://10.0.0.101:9200/_aliases

{
    "actions":[
        {
          "add":{
                "index":"yedu-linux85",
                "alias":"Linux容器运维"
           }   
        },
        {
           "add":{
                "index":"yedu-linux85",
                "alias":"DBA"
            }
        }
    ]
}

成功案例：

2.给多个索引添加别名

bash 复制代码

POST http://10.0.0.151:9200/_aliases
{
    "actions": [
        {
            "add": {
                "index": "yedu-linux85",
                "alias": "Linux2023"
            }
        },
         {
            "add": {
                "index": "yedu-linux86",
                "alias": "Linux2023"
            }
        },
         {
            "add": {
                "index": "yedu-linux87",
                "alias": "Linux2023"
            }
        }
    ]
}

（二）查看索引别名

1.查看索引别名

bash 复制代码

http://10.0.0.151:9200/_aliases
{
    "yedu-linux85": {
        "aliases": {
            "DBA": {},
            "Linux2023": {},
            "Linux容器运维": {}
        }
    },
    "yedu-linux86": {
        "aliases": {
            "Linux2023": {}
        }
    },
    "yedu-linux87": {
        "aliases": {
            "Linux2023": {}
        }
    },
    "oldboyedu-linux85": {
        "aliases": {}
    }
}

（三）删除索引别名

1.删除索引别名

bash 复制代码

POST http://10.0.0.151:9200/_aliases
{
    "actions": [
        {
            "remove": {
                "index": "yedu-linux85",
                "alias": "Linux2023"
            }
        },
         {
            "remove": {
                "index": "yedu-linux86",
                "alias": "Linux2023"
            }
        }
    ]
}

（四）修改索引别名

1.修改索引别名

先删除后添加

bash 复制代码

POST http://10.0.0.151:9200/_aliases
{
    "actions": [
        {
            "remove": {
                "index": "yedu-linux85",
                "alias": "DBA"
            }
        },
         {
            "add": {
                "index": "yedu-linux85",
                "alias": "数据库运维工程师"
            }
        }
    ]
}

二、关闭索引

bash 复制代码

POST 10.0.0.151:9200/yedu-linux85/_close

三、打开索引

bash 复制代码

POST 10.0.0.151:9200/yedu-linux85/_open

四、索引默认开发规范

bash 复制代码

    GET :
            https://www.yedu.com/stadent/view_1001
            https://www.yedu.com/stadent/get_1001
    POST:

    DELTE:
            https://www.yedu.com/stadent/del_1001
