如何使用NodeJS以超级用户身份连接到另一个MongoDB数据库? [英] How to connect to another MongoDB database as superuser using NodeJS?

问题描述

此问题的解决方案效果很好:

代替:

$ mongo my_db_name -u superuser -p 1234

我愿意

$ mongo admin -u superuser -p 1234 # connecting as super user to admin db
> use anotherDb

在外壳中.

NodeJS中的解决方案是什么?

我尝试连接到mongodb://superuser:1234@localhost:27017/my_db_name，但出现此错误:

{ [MongoError: auth fails] name: 'MongoError', code: 18, ok: 0, errmsg: 'auth fails' }

我的代码是:

var Db = require('mongodb').Db,
    MongoClient = require('mongodb').MongoClient;

MongoClient.connect("mongodb://superuser:1234@localhost:27017/my_db_name",
    function(err, db) {
       if (err) { return console.log(err); }
       console.log("Successfully connected.");
    }
); 

请注意，超级用户是无所不能的用户，可以在任何数据库中写入和读取权限.

如果我执行MongoClient.connect("mongodb://superuser:1234@localhost:27017/admin(用admin替换my_db_name)，则说明连接成功.为什么?

如何使用superuser和密码(1234)连接到my_db_name?

解决方案

一种解决方案是使用从Node.js端执行的shell脚本:

mongo <<EOF
use admin
db.auth("superuser", "1234");
use another_db
db.addUser({
   user: "test",
   pwd: "12345",
   roles: ["userAdmin"]
});
exit
EOF

然后，我可以使用以下连接字符串:"mongodb://test:12345@localhost:27017/my_db_name".

此解决方案有效，但我仍在寻找Mongo本地解决方案.

The solution to this problem works fine:

Instead of doing:

$ mongo my_db_name -u superuser -p 1234

I do

$ mongo admin -u superuser -p 1234 # connecting as super user to admin db
> use anotherDb

in shell.

Which is the solution in NodeJS?

I tried to connect to mongodb://superuser:1234@localhost:27017/my_db_name but I get this error:

{ [MongoError: auth fails] name: 'MongoError', code: 18, ok: 0, errmsg: 'auth fails' }

My code is:

var Db = require('mongodb').Db,
    MongoClient = require('mongodb').MongoClient;

MongoClient.connect("mongodb://superuser:1234@localhost:27017/my_db_name",
    function(err, db) {
       if (err) { return console.log(err); }
       console.log("Successfully connected.");
    }
); 

Note that superuser is the omnipotent user that can write and read rights in any database.

If I do MongoClient.connect("mongodb://superuser:1234@localhost:27017/admin (replaced my_db_name with admin) it connects successfully. Why?

How can I connect to the my_db_name using superuser and the password (1234)?

解决方案

A solution would be to use a shell script that is executed from Nodejs side:

mongo <<EOF
use admin
db.auth("superuser", "1234");
use another_db
db.addUser({
   user: "test",
   pwd: "12345",
   roles: ["userAdmin"]
});
exit
EOF

Then I am able to use the following connection string: "mongodb://test:12345@localhost:27017/my_db_name".

This solution works, but I am still looking for the Mongo native solution.
