es之索引的別名操作

1：增加別名

為索引school添加一個別名alias1：

1.1：創建索引

PUT student
{
  "settings": {"number_of_shards": 3 , "number_of_replicas": 1}
}
​
PUT school
{
  "settings": {"number_of_shards": 3 , "number_of_replicas": 1}
}

1.2：添加別名

POST _aliases
{
  "actions" : [{"add" : {"index" : "school" , "alias" : "in1"}}]
}
​
POST _aliases
{
  "actions" : [{"add" : {"index" : "student" , "alias" : "in1"}}]
}

2：查詢別名

查詢某個index下的別名：

GET school/_alias/*

3：刪除別名

POST /_aliases
{
    "actions": [
        {"remove": {"index": "school", "alias": "in1"}}
    ]
}

4：修改別名

es沒有修改別名的操作，只能先刪除后添加

POST _aliases
{
  "actions" : [{"remove" : {"index" : "student" , "alias" : "in1"}}],
  "actions" : [{"add" : {"index" : "student" , "alias" : "in2"}}]
}
