docker run啟動elastic服(fu)務

docker pull elasticsearch:6.7.2

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.7.2

elastic常用命令

查看集群是否健康

　　curl 'localhost:9200/_cat/health?v'

獲取集群的節點列表

　　curl 'localhost:9200/_cat/nodes?v'

列出所有索引

curl 'localhost:9200/_cat/indices?v'

建(jian)立名為customer的(de)索引(yin)

　curl -XPUT 'localhost:9200/customer?pretty'

向索引customer,類型(xing)為external,添加數據(ju)

　　curl -XPUT 'localhost:9200/customer/external/1?pretty' -d '
　　{
       　　  "name": "John Doe"
　　}'

獲取數據

獲取customer索引(yin)下類型(xing)為external，id為1的數(shu)據，pretty參數(shu)表示返回結果格式美觀。

   curl -XGET 'localhost:9200/customer/external/1?pretty'

刪除索引 DELETE

curl -XDELETE 'localhost:9200/customer?pretty'

修改數據,如(ru)果不存在，就新增

curl -XPUT 'localhost:9200/customer/external/1?pretty' -d '
　　{

 　　 "name": "John Doe"

　　}'

更新數據

　　curl -XPOST 'localhost:9200/customer/external/1/_update?pretty' -d '
　　{

 　　 "doc": { "name": "Jane Doe", "age": 20 }
　　}'

刪除一條記錄數據

curl -XDELETE 'localhost:9200/customer/external/2?pretty'
