之前的答案解释得很好，我添加了我的答案，以帮助您处理远程密码保护数据库

mongodump --host xx.xxx.xx.xx --port 27017 --db your_db_name --username your_user_name --password your_password --out /target/folder/path

如果你愿意，你可以将所有的集合导出到csv，而不需要指定——fields(将导出所有字段)。

从http://drzon.net/export-mongodb-collections-to-csv-without-specifying-fields/运行这个bash脚本

OIFS=$IFS;
IFS=",";

# fill in your details here
dbname=DBNAME
user=USERNAME
pass=PASSWORD
host=HOSTNAME:PORT

# first get all collections in the database
collections=`mongo "$host/$dbname" -u $user -p $pass --eval "rs.slaveOk();db.getCollectionNames();"`;
collections=`mongo $dbname --eval "rs.slaveOk();db.getCollectionNames();"`;
collectionArray=($collections);

# for each collection
for ((i=0; i<${#collectionArray[@]}; ++i));
do
    echo 'exporting collection' ${collectionArray[$i]}
    # get comma separated list of keys. do this by peeking into the first document in the collection and get his set of keys
    keys=`mongo "$host/$dbname" -u $user -p $pass --eval "rs.slaveOk();var keys = []; for(var key in db.${collectionArray[$i]}.find().sort({_id: -1}).limit(1)[0]) { keys.push(key); }; keys;" --quiet`;
    # now use mongoexport with the set of keys to export the collection to csv
    mongoexport --host $host -u $user -p $pass -d $dbname -c ${collectionArray[$i]} --fields "$keys" --csv --out $dbname.${collectionArray[$i]}.csv;
done

IFS=$OIFS;

可以使用mongodb命令进行修改

步骤1:打开命令提示符 第二步:打开mongoDB安装的bin文件夹(C:\Program Files\ mongoDB \Server\4.0\bin) 步骤3:然后执行以下命令 mongodb -d your_db_name -o destination_path Your_db_name = test destination_path = C:\Users\HP\Desktop

导出的文件将创建在destination_path\your_db_name文件夹中(在本例中是C:\Users\HP\Desktop\test)

以下是恢复导出数据库时对我有效的方法:

Mongorestore -d 0 ./0——drop

其中。/包含导出的bson文件。注意——drop将覆盖现有数据。

这是我用来实现该结果的bash脚本。该脚本被概括为4个输入(主机url、数据库、用户名和密码)，因此可以在任何mongo数据库上使用。

dburl=$1
username=$3
password=$4
db=$2

mongoAccess=mongodb+srv://$username:$password@$dburl/$db

Collections=$(mongo $mongoAccess --quiet --eval "db.getCollectionNames()" | sed 's/,/ /g' | tail +6)

#echo $Collections

for col in $Collections
do
    if [ "$col" = "[" ] || [ "$col" = "]" ]
    then
        continue
    else
        echo "Exporting $col"
        mongoexport --uri $mongoAccess --collection=$col --type json --out output-$col.json
    fi
    
done

如果你想使用mongoexport和mongoimport从数据库中导出/导入每个集合，我认为这个实用程序会对你有帮助。 我用过几次类似的效用;

LOADING=false

usage()
{
    cat << EOF
    usage: $0 [options] dbname

    OPTIONS:
        -h      Show this help.
        -l      Load instead of export
        -u      Mongo username
        -p      Mongo password
        -H      Mongo host string (ex. localhost:27017)
EOF
}

while getopts "hlu:p:H:" opt; do
    MAXOPTIND=$OPTIND

    case $opt in 
        h)
            usage
            exit
            ;;
        l)
            LOADING=true
            ;;
        u)
            USERNAME="$OPTARG"
            ;;
        p) 
            PASSWORD="$OPTARG"
            ;;
        H)
            HOST="$OPTARG"
            ;;
        \?)
            echo "Invalid option $opt"
            exit 1
            ;;
    esac
done

shift $(($MAXOPTIND-1))

if [ -z "$1" ]; then
    echo "Usage: export-mongo [opts] <dbname>"
    exit 1
fi

DB="$1"
if [ -z "$HOST" ]; then
    CONN="localhost:27017/$DB"
else
    CONN="$HOST/$DB"

ARGS=""

    ARGS="-u $USERNAME"
