mongodb 以管理员登录并创建 database

甜思思

　　mongodb 以管理员登录并创建 database
　　在一个有了用户名的数据库集中,即使在 admin 数据库中创建了用户,登录上去后还是不能访问其他数据库的,但是用   登录是可以的呀,虽然可以在相应数据库中再建立用户,但别的程序都不用是怎么回事?
　　
　　原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"
　　关键字来源于 C# 的错误提示:
　　"
　　An unhandled exception of type 'MongoDB.Driver.MongoAuthenticationException' occurred in MongoDB.Driver.dll
Additional information: Invalid credentials for database 'demoBaseaaa'.
　　"
　　本来想查找 mongodb.exe 中是怎么实现的 use,结果发现它调用 js..  找了半天也没找到 C# 如何实现这样的先 use admin 再 use 普通 database 的,看来 API 和它的 shell tool 实现还是有差异.

ALH 查看个人资料 翻译成中文（简体） 更多选项 1月19日, 上午12时05分 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.

ALH 查看个人资料 翻译成中文（简体） 更多选项 1月27日, 下午8时22分 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. 　　Invalid credentials for database 'SomeTestDatabase'.     at MongoDB.Driver.Internal.MongoConnection.Authenticate(String databaseName, MongoCredentials credentials) in C:\work\10gen\mongodb \mongo-csharp-driver\Driver\Internal\MongoConnection.cs:line 165     at MongoDB.Driver.Internal.MongoConnection.CheckAuthentication(MongoDatabase database) in C:\work\10gen\mongodb\mongo-csharp-driver\Driver\Internal \MongoConnection.cs:line 244     at MongoDB.Driver.MongoServerInstance.AcquireConnection(MongoDatabase database) in C:\work\10gen\mongodb\mongo-csharp-driver\Driver\Core \MongoServerInstance.cs:line 260     at MongoDB.Driver.MongoServer.AcquireConnection(MongoDatabase database, Boolean slaveOk) in C:\work\10gen\mongodb\mongo-csharp-driver \Driver\Core\MongoServer.cs:line 1052     at MongoDB.Driver.MongoCursorEnumerator`1.AcquireConnection() in C: \work\10gen\mongodb\mongo-csharp-driver\Driver\Core \MongoCursorEnumerator.cs:line 184     at MongoDB.Driver.MongoCursorEnumerator`1.GetFirst() in C:\work \10gen\mongodb\mongo-csharp-driver\Driver\Core \MongoCursorEnumerator.cs:line 194     at MongoDB.Driver.MongoCursorEnumerator`1.MoveNext() in C:\work \10gen\mongodb\mongo-csharp-driver\Driver\Core \MongoCursorEnumerator.cs:line 126     at MongoDB.Driver.MongoDatabase.GetCollectionNames() in C:\work \10gen\mongodb\mongo-csharp-driver\Driver\Core\MongoDatabase.cs:line 662     at MongoDB.Driver.MongoDatabase.CollectionExists(String collectionName) in C:\work\10gen\mongodb\mongo-csharp-driver\Driver \Core\MongoDatabase.cs:line 305 　　Thanks. 　　Best Regards, RelayHealth Albert L.

Robert Stam 查看个人资料 翻译成中文（简体） 更多选项 1月27日, 下午11时07分 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). 　　On Jan 27, 7:22 am, ALH  wrote: - 显示引用的文字 -

　　里面说帮助页面上有说明的,看了一下的确有..就是说得太隐晦了:

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.
　　嗯,主要是我英文太烂,又没想到它的字符串示例没列出来完.
