Mongodb 之 數據庫備份恢復步驟

1、查看test數據庫數據

2、備份當前數據庫

[root@ops-site mongodb_backup]# mongodump  -h 10.3.152.78 -u test2 -p abc123 -d test -o .
2019-07-16T23:09:17.902+0800    writing test.runoob to test/runoob.bson
2019-07-16T23:09:17.912+0800    writing test.system.indexes to test/system.indexes.bson
2019-07-16T23:09:17.917+0800    writing test.runoob metadata to test/runoob.metadata.json
2019-07-16T23:09:17.918+0800    done dumping test.runoob (1 document)

3、刪除test數據庫

4、恢復數據庫

[root@ops-site ~]# mongorestore -h 10.3.152.78 -u test2 -p "abc123" -d test /app/backup/mongodb_backup/test/
2019-07-16T23:16:09.928+0800    building a list of collections to restore from /app/backup/mongodb_backup/test/ dir
2019-07-16T23:16:09.938+0800    reading metadata file from /app/backup/mongodb_backup/test/runoob.metadata.json
2019-07-16T23:16:09.938+0800    restoring test.runoob from file /app/backup/mongodb_backup/test/runoob.bson
2019-07-16T23:16:11.055+0800    restoring indexes for collection test.runoob from metadata
2019-07-16T23:16:11.056+0800    finished restoring test.runoob (1 document)
