elasticdump数据迁移方法

 一、安装node

wget https://nodejs.org/dist/v10.13.0/node-v10.13.0-linux-x64.tar.gz
tar xf node-v10.13.0-linux-x64.tar.gz -C /usr/local/
echo 'export PATH=/usr/local/node-v10.13.0-linux-x64/bin/:$PATH' >>/etc/profile
source /etc/profile

二、安装elasticdump

# 全局安装 -g
npm install elasticdump -g

三、通过elasticdump将input中的索引导入到output中

# Copy an index from production to staging with analyzer and mapping: 
elasticdump \
  --input=http://192.168.5.101:9200/my_index \
  --output=http://192.168.5.202:9200/my_index \
  --type=analyzer
elasticdump \
  --input=http://192.168.5.101:9200/my_index \
  --output=http://192.168.5.202:9200/my_index \
  --type=mapping
elasticdump \
  --input=http://192.168.5.101:9200/my_index \
  --output=http://192.168.5.202:9200/my_index \
  --type=data
 
# Backup index data to a file: 
elasticdump \
  --input=http://192.168.5.101:9200/my_index \
  --output=/data/my_index_mapping.json \
  --type=mapping
elasticdump \
  --input=http://192.168.5.101:9200/my_index \
  --output=/data/my_index.json \
  --type=data
