elasticsearch 通过curl的操作_elasticsearch的curl操作-优快云博客

1：curl

curl -h来查看请求参数的含义
-v 显示请求的信息
-X 选项指定其它协议

get:
   curl -v 127.0.0.1:8080/users/age/18

post:
   curl -v 127.0.0.1:8080/users -d 'age=14&cupSize=C'
   curl -v -X POST 127.0.0.1:8080/users -d 'age=14&cupSize=C'

put:
   curl -v -X PUT -d "age=19&cupSize=C" 127.0.0.1:8080/users/3

delete:
curl -v -X DELETE 127.0.0.1:8080/users/3

2:elasticsearch

检查运行

root@micro-node3:/opt/application# curl http://localhost:9200/
{
  "name" : "micro-node3",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "B6DsBJbGSp6UMc-uxKC1zg",
  "version" : {
    "number" : "7.3.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "de777fa",
    "build_date" : "2019-07-24T18:30:11.767338Z",
    "build_snapshot" : false,
    "lucene_version" : "8.1.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

集群健康

root@micro-node3:/opt/application# curl -X GET localhost:9200/_cat/health?v
epoch      timestamp cluster       status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1634371100 07:58:20  elasticsearch yellow          1         1      1   1    0    0        1             0                  -                 50.0%

请求集群健康时，会得到green, yellow, 或者 red 这三种状态。

Green ： everything is good（一切都很好）（所有功能正常）
Yellow ：所有数据都是可用的，但有些副本还没有分配（所有功能正常）
Red ：有些数据不可用（部分功能正常）
