Question

所以我准备好了mongodb实例，打开远程连接。

由于某些原因，我无法将其与用户连接/传递而没有--authenticationDatabase admin 添加到连接字符串。

当我尝试与用户/传递单独执行连接时（没有＆＃34; authenticationDatabase＆＃34;，我得到：

2015-02-01T16:07:24.818-0500 Error: 18 { ok: 0.0, errmsg: "auth failed", code: 18 } at src/mongo/shell/db.js:1210
exception: login failed

Answer 1

这是因为用户凭据存储在管理数据库中，不存储在mongo shell连接到的（默认）数据库中（测试）。

您可以使用连接网址进行更改：

使用admin数据库：

$ mongo localhost/admin --username user -p
MongoDB shell version: 2.6.9
Enter password:
connecting to: localhost/admin
replset:PRIMARY>

没有特定数据库（默认为test）：

$ mongo localhost --username user -p
MongoDB shell version: 2.6.9
Enter password:
connecting to: localhost
2015-04-22T15:34:28.743+0100 Error: 18 { ok: 0.0, errmsg: "auth failed", code: 18 } at src/mongo/shell/db.js:1260
exception: login failed

使用--authenticationDatabase：

$ mongo localhost --username user --authenticationDatabase admin -p
MongoDB shell version: 2.6.9
Enter password:
connecting to: localhost
replset:PRIMARY>

请注意，使用--host不会假设数据库名称是/之后的名称（斜杠：

$ mongo --host localhost/admin --username user -p
MongoDB shell version: 2.6.9
Enter password:
connecting to: localhost/admin:27017/test

Answer 2

感谢@Gianfranco P。

简要说明：如果要连接到没有authenticationDatabase选项的数据库，则应在要连接的同一数据库中创建用户。

例如

mongodb://demouser:demopass@<host>:<port>/demodb

对于此URI，您应该在demouser数据库中创建demodb用户，否则您必须提供authenticationDatabase这样的选项

mongodb://demouser:demopass@<host>:<port>/demodb?authSource=<authDatabase>

没有＆＃34;连接到mongodb实例 - authenticationDatabase admin＆＃34;
