ELK学习笔记之使用curl命令操作elasticsearch

0x00 _cat系列

_cat系列提供了一系列查询elasticsearch集群状态的接口。你可以通过执行
curl -XGET localhost:9200/_cat

1. 获取所有_cat系列的操作

/_cat/allocation
/_cat/shards
/_cat/shards/{index}
/_cat/master
/_cat/nodes
/_cat/indices
/_cat/indices/{index}
/_cat/segments
/_cat/segments/{index}
/_cat/count
/_cat/count/{index}
/_cat/recovery
/_cat/recovery/{index}
/_cat/health
/_cat/pending_tasks
/_cat/aliases
/_cat/aliases/{alias}
/_cat/thread_pool
/_cat/plugins
/_cat/fielddata
/_cat/fielddata/{fields}

你也可以后面加一个v，让输出内容表格显示表头，举例

Onyxx      analysis-pinyin  NA      j
Onyxx      head             NA      s    /_plugin/head/
Onyxx      bigdesk          NA      s    /_plugin/bigdesk/

0x01 _cluster系列

1、查询设置集群状态

curl -XGET localhost:9200/_cluster/health?pretty=true

pretty=true表示格式化输出
level=indices 表示显示索引状态
level=shards 表示显示分片信息

2、显示集群系统信息，包括CPU JVM等等

curl -XGET localhost:9200/_cluster/stats?pretty=true

3、 集群的详细信息。包括节点、分片等。

curl -XGET localhost:9200/_cluster/state?pretty=true

3、获取集群堆积的任务

curl -XGET localhost:9200/_cluster/pending_tasks?pretty=true 

4、修改集群配置

curl -XPUT localhost:9200/_cluster/settings -d '{
    "persistent" : {
        "discovery.zen.minimum_master_nodes" : 2
    }
}'

transient 表示临时的，persistent表示永久的

5、对shard的手动控制

curl -XPOST ‘localhost:9200/_cluster/reroute’ -d ‘xxxxxx’

对shard的手动控制，参考http://zhaoyanblog.com/archives/687.html

6、关闭节点

关闭指定192.168.1.1节点

curl -XPOST ‘http://192.168.1.1:9200/_cluster/nodes/_local/_shutdown’
curl -XPOST ‘http://localhost:9200/_cluster/nodes/192.168.1.1/_shutdown’

7、关闭主节点

curl -XPOST ‘http://localhost:9200/_cluster/nodes/_master/_shutdown’

8、关闭整个集群

$ curl -XPOST ‘http://localhost:9200/_shutdown?delay=10s’
$ curl -XPOST ‘http://localhost:9200/_cluster/nodes/_shutdown’
$ curl -XPOST ‘http://localhost:9200/_cluster/nodes/_all/_shutdown’

delay=10s表示延迟10秒关闭

0x02 _nodes系列

1、查询节点的状态
curl -XGET ‘http://localhost:9200/_nodes/stats?pretty=true’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2/stats?pretty=true’
curl -XGET ‘http://localhost:9200/_nodes/process’
curl -XGET ‘http://localhost:9200/_nodes/_all/process’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/jvm,process’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/info/jvm,process’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/_all
curl -XGET ‘http://localhost:9200/_nodes/hot_threads

0x03 索引操作

1、获取索引

curl -XGET ‘http://localhost:9200/{index}/{type}/{id}’

2、索引数据

curl -XPOST ‘http://localhost:9200/{index}/{type}/{id}’ -d'{“a”:”avalue”,”b”:”bvalue”}’

3、删除索引

curl -XDELETE ‘http://localhost:9200/{index}/{type}/{id}’

4、设置mapping

curl -XPUT http://localhost:9200/{index}/{type}/_mapping -d '{
  "{type}" : {
    "properties" : {
      "date" : {
        "type" : "long"
      },
      "name" : {
        "type" : "string",
        "index" : "not_analyzed"
      },
      "status" : {
        "type" : "integer"
      },
      "type" : {
        "type" : "integer"
      }
    }
  }
}'

5、获取mapping

curl -XGET http://localhost:9200/{index}/{type}/_mapping

6、搜索

curl -XGET 'http://localhost:9200/{index}/{type}/_search' -d '{
    "query" : {
        "term" : { "user" : "kimchy" } //查所有 "match_all": {}
    },
    "sort" : [{ "age" : {"order" : "asc"}},{ "name" : "desc" } ],
    "from":0,
    "size":100
}
curl -XGET 'http://localhost:9200/{index}/{type}/_search' -d '{
    "filter": {"and":{"filters":[{"term":{"age":""}},{"term":{"name":"张三"}}]},
    "sort" : [{ "age" : {"order" : "asc"}},{ "name" : "desc" } ],
    "from":0,
    "size":100
}
