คำตอบที่เลือกทำให้ฟังดูซับซ้อนกว่าที่เป็นอยู่เล็กน้อยสิ่งต่อไปนี้คือสิ่งที่คุณต้องการ (ติดตั้ง npm ก่อนในระบบของคุณ)
npm install -g elasticdump
elasticdump --input=http://mysrc.com:9200/my_index --output=http://mydest.com:9200/my_index --type=mapping
elasticdump --input=http://mysrc.com:9200/my_index --output=http://mydest.com:9200/my_index --type=data
คุณสามารถข้ามคำสั่ง elasticdump แรกสำหรับสำเนาที่ตามมาได้หากการแม็ปยังคงคงที่
ฉันเพิ่งทำการย้ายข้อมูลจาก AWS ไปยัง Qbox.io โดยไม่มีปัญหาใด ๆ

หน้าช่วยเหลือ (ณ เดือนกุมภาพันธ์ 2016) รวมไว้เพื่อความสมบูรณ์:
elasticdump: Import and export tools for elasticsearch
Usage: elasticdump --input SOURCE --output DESTINATION [OPTIONS]
--input
Source location (required)
--input-index
Source index and type
(default: all, example: index/type)
--output
Destination location (required)
--output-index
Destination index and type
(default: all, example: index/type)
--limit
How many objects to move in bulk per operation
limit is approximate for file streams
(default: 100)
--debug
Display the elasticsearch commands being used
(default: false)
--type
What are we exporting?
(default: data, options: [data, mapping])
--delete
Delete documents one-by-one from the input as they are
moved. Will not delete the source index
(default: false)
--searchBody
Preform a partial extract based on search results
(when ES is the input,
(default: '{"query": { "match_all": {} } }'))
--sourceOnly
Output only the json contained within the document _source
Normal: {"_index":"","_type":"","_id":"", "_source":{SOURCE}}
sourceOnly: {SOURCE}
(default: false)
--all
Load/store documents from ALL indexes
(default: false)
--bulk
Leverage elasticsearch Bulk API when writing documents
(default: false)
--ignore-errors
Will continue the read/write loop on write error
(default: false)
--scrollTime
Time the nodes will hold the requested search in order.
(default: 10m)
--maxSockets
How many simultaneous HTTP requests can we process make?
(default:
5 [node <= v0.10.x] /
Infinity [node >= v0.11.x] )
--bulk-mode
The mode can be index, delete or update.
'index': Add or replace documents on the destination index.
'delete': Delete documents on destination index.
'update': Use 'doc_as_upsert' option with bulk update API to do partial update.
(default: index)
--bulk-use-output-index-name
Force use of destination index name (the actual output URL)
as destination while bulk writing to ES. Allows
leveraging Bulk API copying data inside the same
elasticsearch instance.
(default: false)
--timeout
Integer containing the number of milliseconds to wait for
a request to respond before aborting the request. Passed
directly to the request library. If used in bulk writing,
it will result in the entire batch not being written.
Mostly used when you don't care too much if you lose some
data when importing but rather have speed.
--skip
Integer containing the number of rows you wish to skip
ahead from the input transport. When importing a large
index, things can go wrong, be it connectivity, crashes,
someone forgetting to `screen`, etc. This allows you
to start the dump again from the last known line written
(as logged by the `offset` in the output). Please be
advised that since no sorting is specified when the
dump is initially created, there's no real way to
guarantee that the skipped rows have already been
written/parsed. This is more of an option for when
you want to get most data as possible in the index
without concern for losing some rows in the process,
similar to the `timeout` option.
--inputTransport
Provide a custom js file to us as the input transport
--outputTransport
Provide a custom js file to us as the output transport
--toLog
When using a custom outputTransport, should log lines
be appended to the output stream?
(default: true, except for `$`)
