1 ,检查所有的节点是否已经加入集群

http://localhost:9200/_cat/health

http://localhost:9200/_cat/nodes

2,集群的恢复情况

http://localhost:9200/_cat/recovery

3,时间参数的URL ，URL编码问题将/转换为%2F

//shop_202004  
http://localhost:9200/<shop_{
    
    now%2FM{
    
    YYYYMM}}>/_search
//shop_2020.04.23
http://localhost:9200/<shop_{
    
    now%2Fd-2d}>/_search

4,查看索引状态

http://localhost:9200/_cat/indices?v

5，插入数据PUT请求

PUT请求
http://localhost:9200/shop_log_202003/shop_log_202003/1/

{
    
    
	"ip":"127.0.0.1",
	"action":"query"
}

6,更新数据doc

POST请求
http://localhost:9200/shop_log_202003/shop_log_202003/1/_update
{
    
    
	"doc": {
    
    
		"ip":"127.0.0.1",
	    "action":"query"
	}
	
}

7，查询文档

 GET请求
http://localhost:9200/shop_log_202003/shop_log_202003/1

结果：
{
    
    
    "_index": "shop_log_202003",
    "_type": "shop_log_202003",
    "_id": "1",
    "_version": 2,
    "found": true,
    "_source": {
    
    
        "ip": "127.0.0.1",
        "action": "query"
    }
}

8，删除文档

http://localhost:9200/shop_log_202003/shop_log_202003/2
{
    
    
    "_index": "shop_log_202003",
    "_type": "shop_log_202003",
    "_id": "2",
    "_version": 2,
    "result": "deleted",
    "_shards": {
    
    
        "total": 1,
        "successful": 1,
        "failed": 0
    },
    "_seq_no": 7,
    "_primary_term": 1
}

9，删除索引库

DELETE请求
http://localhost:9200/shop_log_202003/

10，创建索引设置分片number_of_shards主分片，number_of_replicas副本

PUT请求
http://localhost:9200/shop_log_202004/
{
    
    
		"settings":{
    
    
			"number_of_shards":1,
			"number_of_replicas":0
		}
}
或者
{
    
    
		"settings":{
    
    
			"index":{
    
    
			"number_of_shards":1,
			"number_of_replicas":0
			}
		}
}

11，修改副本数

PUT请求
http://localhost:9200/shop_log_202004/_settings/
{
    
    
	"number_of_replicas": 1
}
