0.查看集群是否健康
GET /_cluster/health
1.查詢所有索引
GET /_cat/indices?v
2.查詢單個索引的映射
GET /index_trans_detail/_mapping
3.刪除index
DELETE /index_trans_detail,index_two
4. 添加字段映射
PUT /index_trans_detail/_mapping/type_trans_detail
{
"properties": {
"tags":{
"type": "text"
}
}
}
5. 索引的別名
5.1 創建索引的別名
PUT /index_trans_detail/_alias/index_trans_detail_alias
5.2 查詢索引的別名
GET /index_trans_detail/_alias/*
5.3 查詢別名指向哪一個索引
GET /*/_alias/index_trans_detail_alias
5.4 刪除別名
DELETE /index_trans_detail/_alias/index_trans_detail_alias
6. 添加一個索引（通過mapping）
PUT /people
{
"settings": {
"number_of_shards": 3,
"number_of_replicas": 1
},
"mappings": {
"man": {
"dynamic": "strict",
"properties": {
"name": {
"type": "text"
},
"age": {
"type": "integer"
},
"birthday": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
},
"address":{
"dynamic": "true",
"type": "object"
}
}
}
}
}
"dynamic": "strict" 表示如果遇到陌生field會報錯
"dynamic": "true" 表示如果遇到陌生字段，就進行dynamic mapping
"dynamic": "false" 表示如果遇到陌生字段，就忽略
7.修改字段可以排序
PUT index_trans_detail/_mapping/activity_dictionary
{
"properties": {
"type_code":{
"type": "text",
"fielddata": true
}
}
}
7.1 添加字段
PUT /index_trans_detail/_mapping/type_trans_detail
{
"properties": {
"tags":{
"type": "text"
}
}
}
通過別名更換索引
==========================================================
8.創建別名
POST _aliases
{
"actions": [
{
"add": {
"index": "old_index",
"alias": "old_index_alias"
}
}
]
}
9.將老的索引中的數據復制到新的索引中：
POST _reindex
{
"source": {
"index": "old_index"（老的索引名）
},
"dest": {
"index": "new_index"（新的索引名）
}
}
10,創建映射
POST _aliases
{
"actions": [
{
"remove": {
"index": "old_index",
"alias": "old_index_alias"
}},
{
"add": {
"index": "new_index",
"alias": "old_index_alias"
}
}
]
}
11.刪除舊索引
DELETE old_index
