kibana的安装和es的使用

在官网下载完kibana（以上篇版本为主v7.3.0）

查看kibana配置

# kibana的默认端口
#server.port: 5601

# 主机地址 填入localhost
server.host: "localhost"

#服务名
server.name: "choviwu"

#es的节点，多个用逗好隔开
#elasticsearch.hosts: ["http://localhost:9200"]

# When this setting's value is true Kibana uses the hostname specified in the server.host
# setting. When the value of this setting is false, Kibana uses the hostname of the host
# that connects to this Kibana instance.
#elasticsearch.preserveHost: true

# kibana 创建默认的索引

# es 请求时间
elasticsearch.requestTimeout: 30000

# List of Kibana client-side headers to send to Elasticsearch. To send *no* client-side
# headers, set this value to [] (an empty list).
#elasticsearch.requestHeadersWhitelist: [ authorization ]

# Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten
# by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration.
#elasticsearch.customHeaders: {}

# Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.
elasticsearch.shardTimeout: 30000

# Time in milliseconds to wait for Elasticsearch at Kibana startup before retrying.
elasticsearch.startupTimeout: 5000

# Logs queries sent to Elasticsearch. Requires logging.verbose set to true.
elasticsearch.logQueries: true

# Set the value of this setting to true to log all events, including system usage information
# and all requests.
logging.verbose: true

# Set the interval in milliseconds to sample system and process performance
# metrics. Minimum is 100ms. Defaults to 5000.
#ops.interval: 5000

#  国际化支持，默认是en  可以该成zh-CN  
# Supported languages are the following: English - en , by default , Chinese - zh-CN .

启动kibana

双击执行bin目录下的kibana.bat/kibana

打开之后可以看到kibana的界面

点击左下角标红的 开发工具，然后执行相应的命令

1、创建索引(类似于创建数据库)：

PUT order

2、创建文档：

PUT order/_doc/1
{
  "orderNo": "B112943294823984T12483",
  "orderId": 19434852,
  "userId": "djsifjfvxh23hsdhuasxhsdfv0",
  "payTime": 1611065280000
}

服务端的响应：

{
  "_index" : "order",  # 索引值
  "_type" : "_doc",    # 类型 doc类型  老版本需要标识type
  "_id" : "1",         # id 文档的id
  "_version" : 1,      #版本号，从1开始，如果更新则version+1
  "result" : "created", # 创建 后面还有updated
  "_shards" : {
    "total" : 2,       
    "successful" : 1,  # 成功
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

然后再执行一遍上面的命令得到

{
  "_index" : "order",
  "_type" : "_doc",
  "_id" : "1",
  "_version" : 2,        # 可以看到版本号+1
  "result" : "updated",  #这里也是更新
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 1,
  "_primary_term" : 1
}

如果id设置为2呢？ 没错，如果是2的话，服务端查询没有这个id，则会新建一条文档，反之update。

查询

term查询

term query，就是精确匹配，执行下面的json则会查询到相应的内容，如果value值有任意一个字符不匹配则不会命中文档

GET order/_search
{
  "query": {
    "term": {
      "orderId": {
        "value": 19434852
      }
    }
  }
}

bool查询

Bool查询对应Lucene中的BooleanQuery，它由一个或者多个子句组成，每个子句都有特定的类型，就像下面那条json，我整理了一下写到了下面表格中

其实这些完全可以从单词字义上可以帮助理解每个类型的功能，must是必须匹配数组下的所有条件才可以，filter为过滤当前匹配的， should为满足其中一个
即可，must_nout是不满足这个条件

GET order/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "orderId": {
              "value": "19434852"
            }
          }
        }
      ],
      "filter": {
        "term": {
          "orderNo": "B112943294823984T12483"
        }
      },
      "should": [
        {
          "match": {
            "orderId": "19434852"
          }
        }
      ]
    }
  }
}
