创建 mongodb 备份并上传到 amazon s3

Question

我试图创建 MongoDB 备份并将其上传到 amazon s3。这是我的脚本。

#!/bin/bash  
#Force file syncronization and lock writes

mongo admin --eval "printjson(db.fsyncLock())"

MONGODUMP_PATH="/home/ubuntu/backup/mongodb"
MONGO_HOST="122.248.238.32"
MONGO_PORT="27017"
MONGO_DATABASE="eb"

TIMESTAMP=`date +%F-%H%M`
S3_BUCKET_NAME="MongodbBackup"
S3_BUCKET_PATH="mongodb-backups"


# Create backup
$MONGODUMP_PATH -h $MONGO_HOST:$MONGO_PORT -d $MONGO_DATABASE

# Add timestamp to backup
mv dump mongodb-$HOSTNAME-$TIMESTAMP
tar cf mongodb-$HOSTNAME-$TIMESTAMP.tar mongodb-$HOSTNAME-$TIMESTAMP

# Upload to S3
s3cmd put mongodb-$HOSTNAME-$TIMESTAMP.tar s3://$S3_BUCKET_NAME/$S3_BUCKET_PATH/mongodb-$HOSTNAME-$TIMESTAMP.tar


#Unlock databases writes
mongo admin --eval "printjson(db.fsyncUnlock())"

当我运行这个脚本时，我得到了这样的响应

MongoDB shell version: 2.4.6
connecting to: admin
{
    "info" : "now locked against writes, use db.fsyncUnlock() to unlock",
    "seeAlso" : "http://dochub.mongodb.org/core/fsynccommand",
    "ok" : 1
}
mv: cannot stat `dump': No such file or directory
tar: mongodb-ip-10-145-167-183-2014-06-02-1055: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

如何正确创建备份并上传到 s3？

Answer 1

替换

$MONGODUMP_PATH -h $MONGO_HOST:$MONGO_PORT -d $MONGO_DATABASE

与

cd $MONGODUMP_PATH
mongodump -h $MONGO_HOST:$MONGO_PORT -d $MONGO_DATABASE
