elasticdump 导出 导入 elasticsearch
elasticdump是比较好用的es数据导出导入工具。
1，安装elasticdump
# npm install elasticdump -g
2，导出es数据
# elasticdump \ --input=http://localhost:9200/pinyin \ --output=/Users/zhangying/test/pinyin.json \ --type=data
3，导入es数据
# elasticdump \ --input=./pinyin.json \ --output=http://localhost:9200 \ --type=data Thu, 03 May 2018 09:52:02 GMT | starting dump Thu, 03 May 2018 09:52:02 GMT | got 4 objects from source file (offset: 0) Thu, 03 May 2018 09:52:02 GMT | sent 4 objects to destination elasticsearch, wrote 4 Thu, 03 May 2018 09:52:02 GMT | got 0 objects from source file (offset: 4) Thu, 03 May 2018 09:52:02 GMT | Total Writes: 4 Thu, 03 May 2018 09:52:02 GMT | dump complete
网上有说用curl也可以，curl -XPOST 'http://localhost:9200/_bulk?pretty' \
-H "Content-Type: application/json" \
--data-binary @pinyin.json，经尝试不成功报以下错误
Malformed action/metadata line [1], expected START_OBJECT or END_OBJECT but found [VALUE_STRING]
4，大数据拆分
# sed -n '1,2p' pinyin.json > pinyin1.json //前二行放一个文件 # sed -n '3,4p' pinyin.json > pinyin2.json //后二行放一个文件
如果数据太大，可以进行拆分，避免导入时挂掉。
