ElasticSearch - 备份和迁移

方案

离线方案

  • Snapshot
  • Reindex
  • Logstash
  • ElasticSearch-dump
  • ElasticSearch-Exporter

增量备份方案

  • logstash

使用快照进行备份

配置信息

注册前要注意配置文件加上: elasticsearch.yml

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

创建仓库

注册一个仓库,存放快照,记住,这里不是生成快照,只是注册一个仓库

    curl -XPUT 'http://10.11.60.5:9200/_snapshot/repo_backup_1' -H 'Content-Type: application/json' -d '{ "type": "fs", "settings": { "location": "/opt/elasticsearch/backup", "max_snapshot_bytes_per_sec": "20mb", "max_restore_bytes_per_sec": "20mb", "compress": true } }'

查看仓库信息:

    curl -XGET 'http://10.11.60.5:9200/_snapshot/repo_backup_1?pretty'

返回内容

    [root@STOR-ES elasticsearch]# curl -XGET 'http://10.11.60.5:9200/_snapshot/repo_backup_1?pretty'
    {
      "repo_backup_1" : {
        "type" : "fs",
        "settings" : {
          "location" : "/opt/elasticsearch/backup",
          "max_restore_bytes_per_sec" : "20mb",
          "compress" : "true",
          "max_snapshot_bytes_per_sec" : "20mb"
        }
      }
    }

创建快照

    curl -XPUT 'http://10.11.60.5:9200/_snapshot/repo_backup_1/snapshot_1?wait_for_completion=true&pretty' -H 'Content-Type: application/json' -d '{ "indices": "bro-2019-09-14,bro-2019-09-15,wmi-2019-09-14,wmi-2019-09-15,syslog-2019-09-14,sylog-2019-09-15", "rename_pattern": "bro_(.+)", "rename_replacement": "dev_bro_$1", "ignore_unavailable": true, "include_global_state": true }'

执行

    {
      "snapshot" : {
        "snapshot" : "snapshot_1",
        "version_id" : 2040399,
        "version" : "2.4.3",
        "indices" : [ "bro-2019-09-14", "bro-2019-09-15", "wmi-2019-09-15", "syslog-2019-09-14", "wmi-2019-09-14" ],
        "state" : "SUCCESS",
        "start_time" : "2019-09-18T05:58:08.860Z",
        "start_time_in_millis" : 1568786288860,
        "end_time" : "2019-09-18T06:02:18.037Z",
        "end_time_in_millis" : 1568786538037,
        "duration_in_millis" : 249177,
        "failures" : [ ],
        "shards" : {
          "total" : 25,
          "failed" : 0,
          "successful" : 25
        }
      }
    }

恢复数据

方案使用场景

迁移考虑的问题

  • 版本问题,从低版本到高版本数据的迁移

  • 多租户的适配问题

多个工厂的数据进入不同index, 原有的数据bro-2019-09-15的数据需要进入factorycode-bro-2019-09-15

  • 多次或者分批迁移数据

  • 数据在迁移时候富化

  • FieldMapping 和 数据信息 分离?
