es 快照方式同步数据

一、备份

1、配置备份目录

修改elasticsearch.yml文件，新增path.repo

path.repo: ["/home/hgzh/my_repo_flode"]
2、创建仓库
put http://192.168.2.177:9200/_snapshot/data_backup

{

    "type": "fs",

    "settings":{

        "location": "/home/base/elasticsearch/backup"

    }

}
{"acknowledged":true}

3、备份索引

put   http://192.168.2.177:9200/_snapshot/data_backup/snapshot_20250409?wait_for_completion=true

{

"indices": "resource_thing_all_*,resource_thing_his_*"

}

4、查看备份状态

get  http://192.168.2.177:9200/_snapshot/data_backup/snapshot_20250409/_status

 

4、打包(多次备份只打包最新生成的文件)

cd /home/base/elasticsearch/backup

tar -czvf backup.tar.gz *

二、恢复

1、将tar包上传到目标服务器

cd /opt/elasticsearch/data/backup

tar -xvf backup.tar.gz

2、配置备份目录

修改elasticsearch.yml文件，新增path.repo

path.repo: ["/opt/elasticsearch/data"]

3、创建仓库
put  http://192.168.2.113:9200/_snapshot/data_backup

{

    "type": "fs",

    "settings":{

        "location": "/opt/elasticsearch/data/backup"

    }

}

4、恢复
post  http://192.168.2.113:9200/_snapshot/data_backup/snapshot_20250409/_restore?wait_for_completion=true

{

"indices": "resource_thing_all_*,resource_thing_his_*"

}

5、通过可视化工具看数据

 

如果是用docker安装，path.repo: ["/home/hgzh/my_repo_flode"] 配置未docker内部路径 /usr/share/elasticsearch/backup
