- 列出所有索引及存储大小
http://IP:9200/_cat/indices?v
[root@pro-3-b ~]# curl 172.31.15.172:9200/_cat/indices?v

- 创建索引
创建索引名为xx，默认会有5个分片，1个索引
[root@pro-3-b ~]# curl -XPUT 172.31.15.172:9200/hello_index?pretty
{
"acknowledged" : true,
"shards_acknowledged" : true,
"index" : "hello_index"
}
- 添加一个类型
curl -XPUT 'IP:9200/XX/external/2?pretty' -d '
{
"gwyy": "John"
}'
[root@pro-3-b ~]# curl -XPUT -H "Content-Type: application/json" '172.31.15.172:9200/hello_index/external/2?pretty' -d '
{
"gwyy": "John"
}'
{
"_index" : "hello_index",
"_type" : "external",
"_id" : "2",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 1
}
- 更新一个类型
curl -XPOST 'IP:9200/XX/external/1/_update?pretty' -d '
{
"doc": {"name": "Jaf"}
}'
[root@pro-3-b ~]# curl -XPOST -H "Content-Type: application/json" '172.31.15.172:9200/hello_index/external/5/_update?pretty' -d '
{
"doc": {"name": "Jaf"}
}'
{
"error" : {
"root_cause" : [
{
"type" : "document_missing_exception",
"reason" : "[external][5]: document missing",
"index_uuid" : "4IRpFzGITlifIBhHR2N1yw",
"shard" : "1",
"index" : "hello_index"
}
],
"type" : "document_missing_exception",
"reason" : "[external][5]: document missing",
"index_uuid" : "4IRpFzGITlifIBhHR2N1yw",
"shard" : "1",
"index" : "hello_index"
},
"status" : 404
}
报错了，404,实际应该修改已经存在的ID。如下所示
[root@pro-3-b ~]# curl -XPOST -H "Content-Type: application/json" '172.31.15.172:9200/hello_index/external/2/_update?pretty' -d '
{
"doc": {"name": "Jaf"}
}'
{
"_index" : "hello_index",
"_type" : "external",
"_id" : "2",
"_version" : 2,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 1,
"_primary_term" : 1
}
- 删除指定索引
curl -XDELETE 'IP:9200/_ index?pretty'
#删除hello_index索引
[root@pro-3-b ~]# curl -XDELETE -H "Content-Type: application/json" '172.31.15.172:9200/hello_index?pretty'
{
"acknowledged" : true
}
