mongodb 以管理人登录并创制 database

mongodb 以管理员登录并创办 database

在一个有了用户名的数据库集中,即便在 admin
数据库中开创了用户,登录上去后要么不可能访问其他数据库的,不过用  
登录是可以的哎,尽管可以在对应数据库中再建立用户,但其它程序都不用是怎么回事?

 

本来是要在用户名后加上 “(admin)” 标识.

例如

            //ok//MongoServer server =
MongoServer.Create(“mongodb://root:111@192.168.0.34:27017/?connect=direct;slaveOk=true”);
// connect to localhost
            MongoServer server =
MongoServer.Create(“mongodb://root(admin):111@192.168.0.34:27017/?connect=ReplicaSet;slaveOk=true”);
// connect to localhost
是在以下找到的,用的 baidu 关键字 “MongoDatabase GetDatabase Invalid
credentials for database”

重点字来源于 C# 的错误提醒:

An unhandled exception of type
‘MongoDB.Driver.MongoAuthenticationException’ occurred in
MongoDB.Driver.dll

Additional information: Invalid credentials for database ‘demoBaseaaa’.

理所当然想查找 mongodb.exe 中是怎么落实的 use,结果发现它调用 js.. 
找了半天也没找到 C# 怎么着落实如此的先 use admin 再 use 普通 database
的,看来 API 和它的 shell tool 实现如故有差别.

How do I create a database from using 10gen C# driver? I have tried
this using the GetDatabase method in MongoServer with no luck. Also,
how would 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 MongoCredentials(“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 the
replica set members.

Hi Robert,

Thanks for the reply. I have ran into some issues with the suggested
approach that I would 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 = MongoServer.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 at
    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 would in SQL Server? I am currently doing this from the mongo
    shell in PowerShell using connect(“MyNewDatabase”). I would 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 the
username in the URL, like this:

var url = “mongodb://
someAdminUser(admin):someAdminUserPassword@localhost:9001″

When you authenticate against the admin database you gain access to
all databases at once (including the new one you are about to create).

Hi Robert,

This totally worked though I could not find this connection string on
the driver docs @

里面说襄助页面上有表达的,看了弹指间真正有..就是说得太生硬了:

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 should 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.

哦,重假若自家英文太烂,又没悟出它的字符串示例没列出来完.
