elasticsearch數(shù)據(jù)備份恢復(fù)-創(chuàng)新互聯(lián)

本文主要介紹elasticsearch集群數(shù)據(jù)備份及恢復(fù)，利用共享文件系統(tǒng)，通過快照方式備份。

集群的部署參考：http://hnr520.blog.51cto.com/4484939/1876467

一、配置修改

1.配置文件必須添加如下參數(shù)

path.repo: /mnt/backups/es_mybak

二、數(shù)據(jù)備份

1.創(chuàng)建備份倉庫

curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup' -d '{ "type": "fs", "settings": { "location": "/mnt/backups/es_mybak" } }' [root@node1 local]# curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup' -d '{ > "type": "fs", > "settings": { > "location": "/mnt/backups/es_mybak" > } > }' {"acknowledged":true}

給我們的倉庫取一個名字，在本例它叫 EsBackup 。

我們指定倉庫的類型應(yīng)該是一個共享文件系統(tǒng)，這里采用nfs。

最后，我們提供一個已掛載的設(shè)備(/mnt/backups/es_mybak )作為目的地址。

注意：共享文件系統(tǒng)路徑必須確保集群所有節(jié)點(diǎn)都可以訪問到。

2.查詢備份倉庫

[root@node1 local]# curl -XGET 'http://192.168.115.11:9200/_snapshot?pretty' { "EsBackup" : { "type" : "fs", "settings" : { "location" : "/mnt/backups/es_mybak" } } }

3.備份所有索引

curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_all' [root@node1 local]# curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_all' {"accepted":true}

4.查看備份快照

curl -XGET 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_all?pretty' [root@node1 elasticsearch6]# curl -XGET 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_*?pretty' { "snapshots" : [ { "snapshot" : "snapshot_all", "uuid" : "MRTYocxBT4qgwtpu_6jdpg", "version_id" : 5000199, "version" : "5.0.1", "indices" : [ "els_student_hnr05", "hnrtest", "els_student_hnr03", "els_student", "els_student_hnr02", "els_student_hnr04", "els_python01", "els_student_hnr01" ], "state" : "SUCCESS", "start_time" : "2017-05-17T10:00:46.860Z", "start_time_in_millis" : 1495015246860, "end_time" : "2017-05-17T10:00:54.209Z", "end_time_in_millis" : 1495015254209, "duration_in_millis" : 7349, "failures" : [ ], "shards" : { "total" : 40, "failed" : 0, "successful" : 40 } } ] }

5.備份部分索引

curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05' -d '{ "indices": "els_student_hnr05" }' [root@node1 elasticsearch6]# curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05' -d '{ "indices": "els_student_hnr05" }' {"accepted":true}

6.查看備份快照

curl -XGET 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05?pretty' 查看快照的詳細(xì)信息，可以看到每個shard的信息 curl -XGET 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05/_status?pretty' [root@node1 elasticsearch6]# curl -XGET 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05?pretty' { "snapshots" : [ { "snapshot" : "snapshot_els_student_hnr05", "uuid" : "hsSkWa63Ss6MJjh0Eo4arA", "version_id" : 5000199, "version" : "5.0.1", "indices" : [ "els_student_hnr05" ], "state" : "SUCCESS", "start_time" : "2017-05-18T00:58:35.699Z", "start_time_in_millis" : 1495069115699, "end_time" : "2017-05-18T00:58:36.396Z", "end_time_in_millis" : 1495069116396, "duration_in_millis" : 697, "failures" : [ ], "shards" : { "total" : 5, "failed" : 0, "successful" : 5 } } ] }

三、.部分索引數(shù)據(jù)恢復(fù)

1.查詢索引

curl -XGET '192.168.115.11:9200/_cat/indices?v' health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open els_student_hnr05 mkvmTguZS4m1wGKbB8TOEw 5 1 99 0 124.7kb 62.3kb green open hnrtest Y-bjuEPLQTGGP88EafDlyg 5 1 0 0 1.5kb 795b green open els_student_hnr03 _UHB6P-fRfucH7lEyE-C7g 5 1 99 0 146.7kb 73.3kb green open els_student JC69IBEjTji8jU6bxCDE3A 5 1 999 0 495.9kb 247.9kb green open els_student_hnr02 k-aLl7tzRUyRfwJs8O0-kA 5 1 99 0 109.8kb 54.9kb green open els_student_hnr04 zAkj7GvfQ-CqmuFMJUTSuA 5 1 99 0 162.8kb 81.4kb green open els_python01 wmdREADVQmCX773_JDL46Q 5 1 0 0 1.5kb 795b green open els_student_hnr01 BJlcIp7mS0ii9nDYj8UDyQ 5 1 100 0 109.2kb 54.6kb

2.刪除索引els_student_hnr05

[root@node1 elasticsearch6]# curl -XDELETE 'http://192.168.115.11:9200/els_student_hnr05' {"acknowledged":true}

3.根據(jù)snapshot_els_student_hnr05快照恢復(fù)索引

curl -XPOST 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05/_restore' [root@node1 elasticsearch6]# curl -XPOST 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05/_restore' {"accepted":true}

4.再次查看索引

被刪除的索引els_student_hnr05已經(jīng)恢復(fù)回來

四、數(shù)據(jù)完全恢復(fù)

1.關(guān)閉所有節(jié)點(diǎn)，刪除數(shù)據(jù)目錄下的所有數(shù)據(jù)，重新啟動集群

kill -9 $(ps -ef | grep -v grep | grep elasticsearch | awk '{print $2}')

2.重新啟動集群

elasticsearch數(shù)據(jù)備份恢復(fù)

3.創(chuàng)建備份倉庫

curl -XPUT 'http://192.168.115.11:9200/_snapshot/EsBackup' -d '{ "type": "fs", "settings": { "location": "/mnt/backups/es_mybak" } }'

4.查看備份快照

curl -XGET 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_*?pretty' { "snapshots" : [ { "snapshot" : "snapshot_all", "uuid" : "MRTYocxBT4qgwtpu_6jdpg", "version_id" : 5000199, "version" : "5.0.1", "indices" : [ "els_student_hnr05", "hnrtest", "els_student_hnr03", "els_student", "els_student_hnr02", "els_student_hnr04", "els_python01", "els_student_hnr01" ], "state" : "SUCCESS", "start_time" : "2017-05-17T10:00:46.860Z", "start_time_in_millis" : 1495015246860, "end_time" : "2017-05-17T10:00:54.209Z", "end_time_in_millis" : 1495015254209, "duration_in_millis" : 7349, "failures" : [ ], "shards" : { "total" : 40, "failed" : 0, "successful" : 40 } }, { "snapshot" : "snapshot_els_student_hnr05", "uuid" : "hsSkWa63Ss6MJjh0Eo4arA", "version_id" : 5000199, "version" : "5.0.1", "indices" : [ "els_student_hnr05" ], "state" : "SUCCESS", "start_time" : "2017-05-18T00:58:35.699Z", "start_time_in_millis" : 1495069115699, "end_time" : "2017-05-18T00:58:36.396Z", "end_time_in_millis" : 1495069116396, "duration_in_millis" : 697, "failures" : [ ], "shards" : { "total" : 5, "failed" : 0, "successful" : 5 } } ] }

5.恢復(fù)數(shù)據(jù)

curl -XPOST 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_all/_restore'

6.查詢索引

[root@node1 elasticsearch6]# curl -XGET '192.168.115.11:9200/_cat/indices?v' health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open hnrtest LNkwevA2Sr2Jgue1oLRIGA 5 1 0 0 1.5kb 795b green open els_student 6aE8M7KMRN2EdievhDBXcw 5 1 999 0 495.9kb 247.9kb green open els_student_hnr04 8hXeVjXYRhS5POdy3hnMuQ 5 1 99 0 162.8kb 81.4kb green open els_student_hnr01 afVLqgxpTqii6pNObLC2sA 5 1 100 0 109.2kb 54.6kb green open els_student_hnr05 jzHPY_TlSEm-ZEXWz0sz4Q 5 1 99 0 124.7kb 62.3kb green open els_student_hnr02 f3hqeM1pQkWttZifnCCQDQ 5 1 99 0 109.8kb 54.9kb green open els_python01 4_vFwhn0RCi3SZbz2bORCw 5 1 0 0 1.5kb 795b green open els_student_hnr03 esFyZMwwTaeLf7YrKxyYjQ 5 1 99 0 146.7kb 73.3kb 至此所有索引已經(jīng)完全恢復(fù)

elasticsearch數(shù)據(jù)備份恢復(fù)

五、從全部索引快照中恢復(fù)單個索引

1.刪除索引els_student_hnr05

curl -XDELETE 'http://192.168.115.11:9200/els_student_hnr05'

2.恢復(fù)被刪除的索引els_student_hnr05

curl -XPOST 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_all/_restore' -d '{ "indices": "els_student_hnr05", "rename_replacement": "restored_index_$1" }'

六、刪除快照

curl -XDELETE 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_els_student_hnr05' curl -XDELETE 'http://192.168.115.11:9200/_snapshot/EsBackup/snapshot_all'
