1，環境搭建：

es（主） nfs（客戶端）	192.168.72.158
es（從） nfs（服務端）	192.168.72.152
es（從） nfs（客戶端）	192.168.72.153

關閉防火牆：systemctl stop firewalld
永久關閉防火牆：systemctl disable firewalld
關閉selinux：sentenforce 0
永久關閉selinux

　　

2，搭建、啟動es叢集

3，安裝nfs

連結: https://pan.baidu.com/s/17p1fl7FM9jMEo-yfe_U0KA密碼: ddgq

cd /nfs
rpm -ivh —nodeps —force *.rpm

啟動nfs
systemctl start rpcbind.service
systemctl start nfs-server.service
開機自啟nfs
systemctl enable rpcbind.service
systemctl enable nfs-server.service

4，建立共享目錄

NFS服務端操作
mkdir -p /data/es/backup
chown -R elasticsearch.elasticsearch /data/es/backup
chmod 755 /data/es/backup
vim /etc/exports
追加以下內容
/data/es/backup 192.168.72.158(rw,sync,all_squash) 192.168.72.152(rw,sync,all_squash) 192.168.72.153(rw,sync,all_squash)
立刻生效
exportfs -r  重新掛載
exportfs -v  顯示共享目錄
export -u  表示解除安裝某一個目錄

nfs客戶端操作，客戶端可以建立任意目錄，目的是用nfs將服務端共享目錄掛載到客戶端本地，實現檔案同步共享。下面客戶端以建立/home/tgram為例 mkdir /home/tgram

5， 掛載共享目錄（服務端客戶端都操作）

mount -t nfs -o nolock,nfsvers=3,vers=3 -o proto=tcp 192.168.72.152:/data/es/backup /home/tgram/

6，修改es配置檔案,重啟es叢集

在elasticsearchc.yml中加入一行
path.repo:    /home/tgram

./elasticsearch &

7,建立備份倉庫

curl -H "Content-Type: application/json" -XPUT 'http://192.168.72.152:9200/_snapshot/EsBackup_zip' -d '{
> "type": "fs",
> "settings": {
> "location": "/home/tgram/compress_snapshot",
> "compress": true
> }
> }'
[2021-01-04T15:36:45,126][INFO ][o.e.r.RepositoriesService] [node01.tgram.com] put repository [EsBackup_zip]
{"acknowledged":true}

8,檢視剛建立的倉庫

[root@localhost home]# curl -XGET 'http://192.168.72.152:9200/_snapshot?pretty'
{
  "EsBackup_zip" : {
    "type" : "fs",
    "settings" : {
      "compress" : "true",
      "location" : "/home/tgram/compress_snapshot"
    }
  }
}

9，備份指定索引資料

（假設要備份全部索引資料, 則可以:）
[root@localhost home]# curl -H "Content-Type: application/json" -XPUT 'http://192.168.72.152:9200/_snapshot/EsBackup_zip/snapshot_all'
[2021-01-04T15:54:14,046][INFO ][o.e.s.SnapshotsService   ] [node01.tgram.com] snapshot [EsBackup_zip:snapshot_all/8nMl1krVQvaI1VkYLg7fKw] started
{"accepted":true}[root@localhost home]# [2021-01-04T15:54:14,125][INFO ][o.e.s.SnapshotsService   ] [node01.tgram.com] snapshot [EsBackup_zip:snapshot_all/8nMl1krVQvaI1VkYLg7fKw] completed with state [SUCCESS]

10,恢復整個快照索引

root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XPOST 'http://192.168.72.158:9200/_snapshot/EsBackup_zip/snapshot_all/_restore'
{"snapshot":{"snapshot":"snapshot_all","indices":[],"shards":{"total":0,"failed":0,"successful":0}}}

11,檢視恢復狀態

[root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XGET  'http://192.168.72.158:9200/_snapshot/EsBackup_zip/snapshot_all/_status'
{"snapshots":[{"snapshot":"snapshot_all","repository":"EsBackup_zip","uuid":"8nMl1krVQvaI1VkYLg7fKw","state":"SUCCESS","include_global_state":true,"shards_stats":{"initializing":0,"started":0,"finalizing":0,"done":0,"failed":0,"total":0},"stats":{"incremental":{"file_count":0,"size_in_bytes":0},"total":{"file_count":0,"size_in_bytes":0},"start_time_i

　　

12，檢視索引、刪除索引

[root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XGET 'http://192.168.72.158:9200/_cat/indices?v'
health status index       uuid                   pri rep docs.count docs.deleted store.size pri.store.size
green  open   commodity   4sUZXNX0SvO3ZbpwlILQ3A   5   1          0            0      2.5kb          1.2kb
green  open   label_11009 0oX0nZU_RK-iflF6filOeg   5   1          1            0      7.7kb          3.8kb


[root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XDELETE 'http://192.168.72.158:9200/commodity'
[2021-01-04T19:20:43,236][INFO ][o.e.c.m.MetaDataDeleteIndexService] [node01.tgram.com] [commodity/4sUZXNX0SvO3ZbpwlILQ3A] deleting index
{"acknowledged":true}


[root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XDELETE 'http://192.168.72.158:9200/label_11009'
[2021-01-04T19:21:00,756][INFO ][o.e.c.m.MetaDataDeleteIndexService] [node01.tgram.com] [label_11009/0oX0nZU_RK-iflF6filOeg] deleting index
{"acknowledged":true}


###再次檢視發現所以已刪除
[root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XGET 'http://192.168.72.158:9200/_cat/indices?v'
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

　　

13，恢復單個索引

[root@localhost compress_snapshot]# curl -H "Content-Type: application/json" -XPOST 'http://192.168.72.158:9200/_snapshot/EsBackup_zip/snapshot2_all/_restore' -d '{ 
> "indices": "label_11009",
> "rename_replacement": "label_22009"
> }'

　　

【注】 本文共設計兩個索引commodity、label_11009 兩個快照snapshot_all、snapshot2_all 一個倉庫compress_snapshot snapshot2_all 快照名稱 commodity 原有索引名稱 label_11009原有索引名稱 label_22009恢復單個索引要替換的名稱 偷襲！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！ https://blog.moguang.me/2017/10/31/bigdata/es-backup-restore-md/#5-%E6%81%A2%E5%A4%8D%E5%A4%87%E4%BB%BD%E7%B4%A2%E5%BC%95
