開始安裝elasticdump:

# npm install elasticdump -g

/usr/bin/elasticdump -> /usr/lib/node_modules/elasticdump/bin/elasticdump

/usr/bin/multielasticdump -> /usr/lib/node_modules/elasticdump/bin/multielasticdump

/usr/lib

從一個索引的資料遷移到另外一個索引的資料:

# elasticdump --ignore-errors=true --scrollTime=120m --bulk=true --input=http://192.168.0.1:9200/test --output=http://192.168.0.1:9200/chenfeng --type=data

備註:

--ignore-errors=true --scrollTime=120m --bulk=true 是批次匯入引數

匯出表結構mapping:

# elasticdump --input=http://192.168.0.1:9200/test --output=test-mapping.json --type=mapping
