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}}}}}
