es日常维护

1.查看es日志
curl -XGET http://10.26.41.60:9200/xdm-logs-2018.08.22?pretty=true

2.删除es日志
curl -XDELETE 'http://10.26.41.60:9200/xdm-logs-2018.08.22?pretty'

3.查询全部,默认返回10条
curl -XPOST '10.26.41.60:9200/xdm-logs-2018.10.22/_search?pretty' -d '
{
"query": { "match_all": {} }
}'

按照updateTime降序返回第一条
curl -H "Content-Type: application/json" -XPOST 'http://10.29.69.243:19200/inoculate/_search?pretty' -d '
{
"query": { "match_all": {} },
"sort": { "updateTime": { "order": "desc" } },
"size": 1
}'

4.查询_id为AWaZRBLvqKSJQKtyjFBL的数据
curl -XPOST '10.26.41.60:9200/xdm-logs-2018.10.22/_search?pretty' -d '
{
"query": { "match": { "_id": "AWaZRBLvqKSJQKtyjFBL" } }
}'

curl -H "Content-Type: application/json" -XPOST 'http://10.29.69.243:19200/inoculate/_search?pretty' -d '
{
"query": { "match": { "childId": "5477456" } }
}'

5.模糊查询
curl -XPOST '10.26.41.60:9200/xdm-logs-2018.10.22/_search?pretty' -d '
{
"query": { "wildcard": { "message": "*2697395*" } }
}'

6.查看所有的index
curl -X GET 'http://10.26.41.60:9200/_cat/indices?v'
kettle入库后进行查询
Select
substr(a,1,instr(a,'2018')-2),
sum(Case When d Like '%gb' Then Substr(d,1,Instr(d,'gb')-1)*1024*1024
When d Like '%mb' Then Substr(d,1,Instr(d,'mb')-1)*1024
When d Like '%kb' Then Substr(d,1,Instr(d,'kb')-1)*1
End) As "kb"
From tb_es_data
Group By
substr(a,1,instr(a,'2018')-2)

7.查看某个index的settings,或者mapping,(pretty=true是指使用易读的方式展现结果)
curl -H "Content-Type: application/json" -XGET "http://10.26.41.60:9200/nginx-logs-2018.09.05/_settings?pretty=true"
curl -H "Content-Type: application/json" -XGET "http://10.26.41.60:9200/nginx-logs-2018.09.05/_mappings?pretty=true"

这里可以查看分片数和副本数
{
"db_customer" : {
"settings" : {
"index" : {
"creation_date" : "1544423489873",
"number_of_shards" : "5",
"number_of_replicas" : "1",
"uuid" : "l77jcDHsR9miIuIKs7RBAA",
"version" : {
"created" : "6050099"
},
"provided_name" : "db_customer"
}
}
}
}

8.获取节点信息
[yeemiao@elk2 etc]$ curl 'http://10.26.41.60:9200/_cat/nodes?v'

9.查看那个是主节点
curl http://192.168.1.134:9200/_cat/master?v

10.设置副本数(这里把单节点的副本数设置为0)
curl -u elastic:elastic -H "Content-Type: application/json" -XPUT 'http://192.168.1.85:9200/db_customer/_settings' -d '{
"number_of_replicas" : 0
}'

11.创建索引并设置其中的mapping的某个字段不进行index
curl -u elastic:elastic -X PUT "192.168.1.85:9200/mytest_index02" -H 'Content-Type: application/json' -d'
{
"mappings": {
"_doc": {
"properties": {
"title": { "type": "text" },
"name": { "type": "text" ,"index": "false" },
"age": { "type": "integer" },
"created": {
"type": "date",
"format": "strict_date_optional_time||epoch_millis"
}
}
}
}
}
'
12.创建index，然后创建mapping

创建一个新的index
curl -u elastic:elastic -H 'Content-Type: application/json' -XPUT "http://192.168.1.85:9200/productindex01"

创建一个mapping
curl -u elastic:elastic -H 'Content-Type: application/json' -XPOST "http://192.168.1.85:9200/productindex01/product01/_mapping?pretty" -d '
{
"product01": {
"properties": {
"title": {
"type": "text",
"store": "true"
},
"description": {
"type": "text",
"index": "false"
},
"price": {
"type": "double"
},
"onSale": {
"type": "boolean"
},
"type": {
"type": "integer"
},
"createDate": {
"type": "date"
}
}
}
}
'
添加一个字段:
curl -u elastic:elastic -H 'Content-Type: application/json' -XPOST "http://192.168.1.85:9200/productindex01/product01/_mapping?pretty" -d '{
"product01": {
"properties": {
"amount":{
"type":"integer"
}
}
}
}'

------------------数据库、表、记录操作-----------------------

创建索引
curl -XPUT 'http://192.168.56.91:9200/db_customer'

添加文档(表)

}'

查看表记录
curl -XGET 'http://10.29.69.243:19200/vacc_update/log/_search?pretty'

红色部分是记录的id
curl -H "Content-Type: application/json" -XPOST 'http://10.29.69.243:19200/vacc_update/log/KxgYJmgBEiGK96VRX--b/_update?pretty' -d '
{
"doc":{"updateTime" : "2018-01-01 00:00:00"}
}'

批处理
curl -H "Content-Type: application/json" -XPOST 'http://192.168.56.91:9200/db_customer/tb_test/_bulk?pretty' -d '
{"index":{"_id":"2"}}
{"name":"zhangsan"}
{"index":{"_id":"3"}}
{"name":"lisi"}
'

查找数据库下的表
curl -XGET "http://192.168.1.134:9200/reservation/_mapping?pretty"

查表里的数据
curl -XGET 'http://192.168.56.91:9200/db_customer/tb_test/_search?pretty'
