使用节点驱动程序在主机之间在Mongodb中克隆数据库 [英] Clone database in Mongodb between hosts using node driver

问题描述

有克隆和 mongodb )?

There are clone and copydb commands available in mongo shell, how to reach them in mongo node native driver(mongodb)?

这就是我尝试过的:

我发现节点本机mongodb驱动程序中可用的db.command.阅读文档时，我尝试了这段代码(db是名为"newdb"的目标数据库)

I discovered the db.command available in node native mongodb driver. Reading documentation I tried this piece of code (db is the destination db named 'newdb')

db = db.db('newdb');
db.addUser('newdbuser', 'newdbpass', {}, function (err) {
    err && console.log(err);
    console.log(authUrlForDb(config.MONGO_HOSTS));
    db.command({
        copydb: 1,
        fromhost: config.MONGO_HOSTS,
        fromdb: config.MOTHER_DB, // some database name
        todb: 'newdb',
        username: config.ADMIN_USERNAME,  //
        key: {
            username: config.ADMIN_USERNAME,
            password: config.ADMIN_PASSWORD
        }
    }, function (err, res) {
        console.log(config.MONGO_HOSTS);
        console.log(err, res);
        db.close();
    });
});

哪个失败并记录以下内容:

Which fails and logs this:

hostname1.host.io,hostname2.host.io
null { ok: 0, errmsg: 'access denied; use admin db' }

推荐答案

您是否尝试过使用 db.admin().command ?

Have you tried using db.admin().command?
