MongoDB误操作后使用oplog恢复数据

Posted in MongoDB onApril 11, 2022

当我们对数据出现误操作的时候，可以利用oplog恢复数据。

使用前提：

  • 1、环境是副本集
  • 2、必须有全备
  • 2、全备后oplog没有被覆盖

数据全备

mongodump -h 172.16.254.133 --port 27017 -o /mongodb/backup/backup

模拟故障

写入数据

handong1:PRIMARY> for (var i = 1; i <= 100; i++) {
...    db.test.insert( { id : i , name: "handong" , name1:"handong", name2:"handong", name3:"handong"} )
... }
WriteResult({ "nInserted" : 1 })
handong1:PRIMARY> 
handong1:PRIMARY> db.test.count()
100

模拟误操作

handong1:PRIMARY> db.test.remove({})
WriteResult({ "nRemoved" : 100 })
handong1:PRIMARY> db.test.count()
0

所有文档被误删除。

恢复步骤

备份oplog

mongodump -h 172.16.254.133 --port 27017 -d local -c oplog.rs -o /mongodb/backup
2021-04-30T18:32:29.077+0800	writing local.oplog.rs to /mongodb/backup/local/oplog.rs.bson
2021-04-30T18:32:32.039+0800	local.oplog.rs  7108
2021-04-30T18:32:35.038+0800	local.oplog.rs  17912

2021-04-30T18:32:47.040+0800	local.oplog.rs  64001
2021-04-30T18:32:50.040+0800	local.oplog.rs  77265
2021-04-30T18:32:53.038+0800	local.oplog.rs  89739
2021-04-30T18:32:56.038+0800	local.oplog.rs  102449
2021-04-30T18:32:57.697+0800	local.oplog.rs  132459
2021-04-30T18:32:57.697+0800	done dumping local.oplog.rs (132459 documents)

解析oplog

bsondump /mongodb/backup/local/oplog.rs.bson  > /mongodb/backup/local/local.log
2021-04-30T18:34:27.612+0800	132459 objects found

将oplog备份和全备复制到standalone机

scp -r backup/ 172.16.254.130:/mongodb/backup/
scp -r local/ 172.16.254.130:/mongodb/backup/backup

查找误操作时间点

通过查看解析完的日志local.log发现误操作的时间点在1619778429。

进行数据恢复
