前言
- 业务须要将 Elasticsearch 快照到 AWS S3,再将快照拷贝到 Windows 零碎,并复原到 Elasticsearch。如下图所示:
- 环境
Elasticsearch 7.10.1
Windows Server 2019
Ubuntu 20.04(ES 宿主)
ES 集群 1 装置 S3 插件
- 官网文档:https://www.elastic.co/guide/…
- 应在 ES 集群的所有节点上装置插件
- 下载 S3 插件和 SHA hash,并上传到 ES 服务器
- 查看并校验

ES 集群 1 增加 KEY
- 应在 ES 集群的所有节点上增加 key
- 查看有哪些 key
/usr/share/elasticsearch/bin/elasticsearch-keystore list
- 增加
access_key
/usr/share/elasticsearch/bin/elasticsearch-keystore add s3.client.default.access_key
- 增加
secret_key
/usr/share/elasticsearch/bin/elasticsearch-keystore add s3.client.default.secret_key
- 重载配置

代替
PUT _snapshot/my_s3_repository

"max_restore_bytes_per_sec": "200mb" # 调整快照复原的速度,默认无限度
}
}
- 查看所有注册的快照仓库
GET _snapshot/_all
- 调整集群复原分片速度和并发数
PUT _cluster/settings {
"transient": {
"indices.recovery.max_bytes_per_sec": "200mb", # 默认 40mb
"cluster.routing.allocation.node_concurrent_recoveries": "5" # 默认 2
}
