Elasticsearch elasticdump的数据导入导出

1、所有备份和导入

安装：

git clone https://github.com/taskrabbit/elasticsearch-dump.git

cd elasticsearch-dump

npm install elasticdump -g

sudo yum install npm

1 2 3 4 5 6 7 8 9 10

(1)建立备份路径 mkdir /data/es_data_backup (2)迁移原机器上的全部索引到目标机器 #把原始索引的mapping结构和数据导出 elasticdump --input=http: //10.200.57.118:9200/ --output=/data/es_data_backup/cmdb_dump-mapping.json --all=true --type=mapping elasticdump --input=http: //10.200.57.118:9200/ --output=/data/es_data_backup/cmdb_dump.json --all=true --type=data   #mapping结构和数据导入新的cluster节点 elasticdump --input=/data/es_data_backup/cmdb_dump-mapping.json --output=http: //10.200.57.118:9200/ --bulk=true elasticdump --input=/data/es_data_backup/cmdb_dump.json --output=http: //10.200.57.118:9200/ --bulk=true

2、指定库备份和导入

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

curl -XGET '192.168.11.10:9200/_cat/indices?v&pretty' .  #查看都有哪些索引 health status index pri rep docs.count docs.deleted store.size pri.store.size green open jyall-test 5 1 18908740 2077368 25gb 12.5gb     # Backup index data to a file: elasticdump --input=http: //10.200.57.118:9200/ele_nginx_clusters --output=/data/es_data_backup/ele_nginx_clusters_mapping.json --type=mapping   elasticdump --input=http: //10.200.57.118:9200/ele_nginx_clusters --output=/data/es_data_backup/ele_nginx_clusters.json --type=data #或者采用gzip的方式,这种方式亲测节省10多倍的空间,导入时gunzip ele_nginx_clusters.json.gz后再进行导入 #Backup and index to a gzip using stdout: elasticdump --input=http: //10.200.57.118:9200/ele_nginx_clusters --output=$ | gzip > /data/es_data_backup/ele_nginx_clusters.json.gz     导入: elasticdump --input=/data/es_data_backup/ele_nginx_clusters_mapping.json --output=http: //10.200.57.118:9200/ --bulk=true elasticdump --input=/data/es_data_backup/ele_nginx_clusters.json --output=http: //10.200.57.118:9200/ --bulk=true

3、导出遇到的报错及问题

1 2 3 4 5 6 7 8 9 10 11 12

(1)报错以下: Thu, 26 Apr 2018 09:14:49 GMT | Error Emitted => read ECONNRESET Thu, 26 Apr 2018 09:14:49 GMT | Total Writes: 19800 Thu, 26 Apr 2018 09:14:49 GMT | dump ended with error ( get phase) => Error: read ECONNRESET (2) <1> It sounds like your issue is being caused by the elasticdump opening too many sockets to your elasticsearch cluster. You can use the --maxSockets option to limit the number of sockets opened. elasticdump --input http: //192.168.2.222:9200/index1 --output http://192.168.2.222:9200/index2 --type=data --maxSockets=5   Reference: https: //stackoverflow.com/questions/33248267/dump-ended-with-error-set-phase-error-read-econnreset https: //github.com/nodejs/node/issues/10563

Elasticsearch6.0数据导入elasticsearch6.7方法：

bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.7.0/elasticsearch-analysis-ik-6.7.0.zip

curl http://192.168.150.116:9210/_cat/plugins

elasticdump --input=http://192.168.150.166:9200/ --output=http://192.168.150.114:9210 --all=true --type=data
