elasticsearch:curl从命令行管理索引

一，创建索引

1，简单创建索引:

[lhdop@blog ~]$ curl -X PUT "localhost:9200/my_suoyin"
{"acknowledged":true,"shards_acknowledged":true,"index":"my_suoyin"}

2, 查看创建索引后的索引列表

[lhdop@blog ~]$ curl -X GET http://localhost:9200/_cat/indices?v
health status index     uuid                   pri rep docs.count docs.deleted store.size pri.store.size dataset.size
yellow open   my_suoyin xReOkZH2RZO8K9Qd5nsZZg   1   1          0            0       249b           249b         249b
yellow open   article1  mI3XlKXZSKOc-a_OheUeWw   1   1          1            0      5.7kb          5.7kb        5.7kb

3, 创建索引时指定选项：要指定使用json格式

说明:

number_of_shards: 每个索引的主分片数，默认值是 5 

number_of_replicas: 每个主分片的副本数，默认值是 1 

[lhdop@blog ~]$ curl -X PUT "localhost:9200/my_suoyin2" -H 'Content-Type: application/json' -d'
{
  "settings": {
    "number_of_shards": 3,
    "number_of_replicas": 0
  }
}'
{"acknowledged":true,"shards_acknowledged":true,"index":"my_suoyin2"}

二，删除索引

1，删除:

[lhdop@blog ~]$ curl -X DELETE "http://localhost:9200/my_suoyin"
{"acknowledged":true}

查看删除索引后的索引列表

[lhdop@blog ~]$ curl -X GET http://localhost:9200/_cat/indices?v
health status index      uuid                   pri rep docs.count docs.deleted store.size pri.store.size dataset.size
green  open   my_suoyin2 pHb14z6RT8-rSWtF0JaMPw   3   0          0            0       747b           747b         747b
yellow open   article1   mI3XlKXZSKOc-a_OheUeWw   1   1          1            0      5.7kb          5.7kb        5.7kb

三，查看es的版本

[lhdop@blog ~]$ /usr/local/soft/elasticsearch-8.14.2/bin/elasticsearch --version
warning: ignoring JAVA_HOME=/usr/local/soft/jdk-17.0.11; using ES_JAVA_HOME
Version: 8.14.2, Build: tar/2afe7caceec8a26ff53817e5ed88235e90592a1b/2024-07-01T22:06:58.515911606Z, JVM: 17.0.11
