es创建索引和mapping
索引和type分开创建
1、创建index
http://127.0.0.1:9200/
negative/ put
{
"settings": {
"index": {
"search": {
"slowlog": {
"threshold": {
"fetch": {
"debug": "5s"
},
"query": {
"warn": "20s"
}
}
}
},
"indexing": {
"slowlog": {
"threshold": {
"index": {
"info": "20s"
}
}
}
},
"number_of_shards": "1",
"number_of_replicas": "0"
}
}
}
2、创建mapping
http://127.0.0.1:9200/
negative/negative/_mapping post
{"properties":{
"id": {
"type": "long"
},
"yjlb": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"ejlb": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"sjlb": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"detail": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"ssyj": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}}
索引和type一次创建
(注意:mapping下面一层的key值 是type名称)
http://192.168.0.213:9200/
announcement/ put
{
"settings": {
"index": {
"search": {
"slowlog": {
"threshold": {
"fetch": {
"debug": "5s"
},
"query": {
"warn": "20s"
}
}
}
},
"indexing": {
"slowlog": {
"threshold": {
"index": {
"info": "20s"
}
}
}
},
"number_of_shards": "1",
"number_of_replicas": "0"
}
},
"mappings": {
"announcement": {
"properties": {
"id": {
"type": "keyword"
},
"createtime": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
},
"creatby": {
"type": "keyword"
},
"updatetime": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
},
"type": {
"type": "keyword"
},
"status": {
"type": "keyword"
},
"title": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"cont": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"files": {
"type": "nested",
"properties": {
"id": {
"type": "keyword"
},
"filename": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
}
}
}
更改elasticsearch中索引的mapping
昨天研发说在kibana中统计userid字段不出图,后来查到该字段显示冲突了,然后再查看了GET test/_mapping下该索引的mapping,发现userid是long类型的,而userid.keyword是string类型的,出现这种情况的根本原因是日志中这个字段存的是数值类型的值,改成字符串类型即可,由于急着用,我司上线一般是下午6点30上线,所以临时修改了下该字段的类型,步骤如下:
查看旧索引的mapping
GET test
/_mapping
找到userid这个字段,修改类型为keyword,如下:
{
"mappings": {
"doc": {
"properties": {
"@timestamp": {
"type": "date"
},
"@version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"beat": {
"properties": {
"hostname": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"code": {
"type": "long"
},
"dip": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"fields": {
"properties": {
"log_topic": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"host": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"message": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"method": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"offset": {
"type": "long"
},
"referer": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"sip": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"source": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"tags": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"time": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"url": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"userid": {
"type": "keyword" #修改此处
}
}
}
}
}
创建一个自定义mapping的新索引
PUT test-new
{
"mappings": {
"doc": {
"properties": {
"@timestamp": {
"type": "date"
},
"@version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"beat": {
"properties": {
"hostname": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"code": {
"type": "long"
},
"dip": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"fields": {
"properties": {
"log_topic": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"host": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"message": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"method": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"offset": {
"type": "long"
},
"referer": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"sip": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"source": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"tags": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"time": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"url": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"userid": {
"type": "keyword"
}
}
}
}
}
把旧索引的数据reindex到新索引上
注意,旧索引先停止新数据的写入
POST _reindex
{
"source": {
"index": "test"
},
"dest": {
"index": "test-new"
}
}
删除旧索引
DELETE test
按照步骤2创建test索引
PUT test
{
"mappings": {
"doc": {
"properties": {
"@timestamp": {
"type": "date"
},
"@version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"beat": {
"properties": {
"hostname": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"code": {
"type": "long"
},
"dip": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"fields": {
"properties": {
"log_topic": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"host": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"message": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"method": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"offset": {
"type": "long"
},
"referer": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"sip": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"source": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"tags": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"time": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"url": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"userid": {
"type": "keyword"
}
}
}
}
}
把test-new索引的数据reindex到test索引上
POST _reindex
{
"source": {
"index": "test-new"
},
"dest": {
"index": "test"
}
}
查看test索引的mapping
GET test/_mapping,执行命令后,可以看到userid的字段类型为keyword类型了
然后再打开该索引接收新数据的开关
