Log on to MongoDB as an administrator and create a database

Log on to MongoDB as an administrator and create a database

In a database with a user name, even if you create a user in the admin database, you still cannot access other databases after logging on, but you can log on to the database, although users can be created in the corresponding databaseProgramWhy?

 

It turns out that "(Admin)" must be added to the user name.

For example

// OK // Login Server = Login server. Create ("MongoDB: // root: 111@192.168.0.34: 27017 /? Connect = direct; slaveok = true "); // connect to localhost
Login Server = Login server. Create ("MongoDB: // root (Admin): 111@192.168.0.34: 27017 /? Connect = replicaset; slaveok = true "); // connect to localhost
The Baidu keyword "relational database getdatabase invalid credentials for Database" is found below"

Keyword error message from C:

"

An unhandled exception of Type 'mongodb. Driver. Your authenticationexception' occurred in MongoDB. Driver. dll

Additional information: invalid credentials for database 'demobaseaaa '.

"

I originally wanted to find out how to implement the use in mongodb.exe, and found that it calls JS .. after looking for a long time, I didn't find C # how to implement this first use admin and then use common database. It seems that the implementation of API and its shell tool is still different.

& Lt; TD width = "100%" & gt; ALH View Personal Data translate to Chinese (simplified) more options August 1, January 19, 12:05 A.M. How do I create a database from using 10gen C # driver? I have tried This using the getdatabase method in Login server with no luck. Also, How wocould I do this if running in Authentication Mode? Is it any Different then running within a replica set? Thanks.

The database will be created automatically when you insert the first Document. When running in Authentication mode you must provide the credentials to use For that database, like this: VaR credentials = New login credentials ("username", "password "); VaR database = server. getdatabase ("databasename", credentials ); The only thing different about running with a replica set is that your Connection string must have a seed list containing all or some of Replica set members. -Display referenced text-

Alh View Personal Data TranslatedChinese (simplified)  More options January 27 08:22 P.M. Hi Robert, Thanks for the reply. I have ran into some issues with the suggested Approach that I wowould like to share with you. So, just to recap: I want to create a new database and then a new collection in that Database. Here is what I am doing in code to achieve the above: // Connect to server VaR url = "MongoDB: // someadminuser: someadminuserpassword @ localhost: 9001/admin" VaR Server = Login server. Create (URL ); // Create my new database VaR DB = server. getdatabase ("somenewdatabase "); // Create my new collection VaR collection = dB. createcollection ("mynewcollection "); Observations: I am running in authenticated mode but the database has not been Create yet, therefore, has no user credentials to authenticate against Questions: 1. Given that I am running in authenticated mode what is the proper Way to connect to the server so that I can create a database that Creation will not have any credentials? (Please see the below Error Message I am getting when executing the above code sample) 2. Is there a way to create a database without writing any data like You wocould in SQL Server? I am currently doing this from the Mongo Shell in powershell using connect ("mynewdatabase"). I wocould be willing To write a createdatabase method if you can provide guidance.

If you want the default credentials supplied in the URL to be Authenticated against the admin database you put "(Admin)" after Username in the URL, like this: VaR url = "MongoDB :// Someadminuser (Admin): someadminuserpassword @ localhost: 9001" When you authenticate against the admin database you gain access All databases at once (including the new one you are about to create ).

It indicates that the Help page is illustrated, and you can see it. That is to say, it is too obscure:

Connection strings

The easiest way to connect to a MongoDB server is to use a connection string. The standard connection string format is:

 
MongoDB:// [Username: password @] hostname [: Port] [/[database] [? Options]
 

The username and password shocould only be present if you are using authentication on the MongoDB server. these credentials will be the default credentials for all databases. to authenticate against the admin database APPEND "(Admin)" to the username. if you are using different credentials with different databases pass the appropriate credentials to the getdatabase method.

Well, I was too bad at English. I didn't expect its string examples to be listed.
