MongoDB 3.2身份验证失败

Question

我使用以下命令集创建用户.这应该在admindb和我的目标db(c2d)中创建用户:

# mongo 127.0.0.1:27017
MongoDB shell version: 3.2.6-29-g5c19788
connecting to: 127.0.0.1:27017/test
> use admin
switched to db admin
> show collections
system.users
system.version
> db.system.users.find()
> db.createUser({user:"cd2", pwd:"cd2", roles:[{role:"dbOwner", db: "c2d"}]})
Successfully added user: {
    "user" : "cd2",
    "roles" : [
        {
            "role" : "dbOwner",
            "db" : "c2d"
        }
    ]
}
> db.system.users.find()
{ "_id" : "admin.cd2", "user" : "cd2", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "4g6t9kC+godz7k6QQOfD+A==", "storedKey" : "m3tDZBQDU2Tlb1lIjLGyTHmr2QQ=", "serverKey" : "GSA4OXSod1s8mBuZBtfmXq2tlTo=" } }, "roles" : [ { "role" : "dbOwner", "db" : "c2d" } ] }
> use c2d
switched to db c2d
> db.createUser({user:"cd2", pwd:"cd2", roles:[{role:"dbOwner", db: "c2d"}]})
Successfully added user: {
    "user" : "cd2",
    "roles" : [
        {
            "role" : "dbOwner",
            "db" : "c2d"
        }
    ]
}
> use admin
switched to db admin
> db.system.users.find()
{ "_id" : "admin.cd2", "user" : "cd2", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "4g6t9kC+godz7k6QQOfD+A==", "storedKey" : "m3tDZBQDU2Tlb1lIjLGyTHmr2QQ=", "serverKey" : "GSA4OXSod1s8mBuZBtfmXq2tlTo=" } }, "roles" : [ { "role" : "dbOwner", "db" : "c2d" } ] }
{ "_id" : "c2d.cd2", "user" : "cd2", "db" : "c2d", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "vnMjnjfykVQS8ujQXeWaYw==", "storedKey" : "OYXivkmIwuTavlwTGfjrspT6j2E=", "serverKey" : "lw8xqzAaW8V4IQ9wOmQrG2VSp88=" } }, "roles" : [ { "role" : "dbOwner", "db" : "c2d" } ] }

如果我尝试登录,我会收到一条错误消息:

# mongo 127.0.0.1:27017/c2d -u c2d -p c2d
MongoDB shell version: 3.2.6-29-g5c19788

DB.prototype._authOrThrow@src/mongo/shell/db.js:1441:20
@(auth):6:1
@(auth):1:2

exception: login failed

然后我在conf文件中启用安全功能并重新启动服务器:

security:
  authorization: enabled

错误仍然是相同的:

# mongo 127.0.0.1:27017/c2d -u c2d -p c2d
MongoDB shell version: 3.2.6-29-g5c19788

好吧,您需要按顺序执行几个步骤才能成功创建用户.

首先,您需要创建一个管理员用户.我更喜欢创建超级用户.

> use admin
> db.createUser({user: "root", pwd: "123456", roles:["root"]})

重新启动MongoDB服务器并使用--authflag 启用身份验证.

> mongod --auth --port 27017 --dbpath /var/lib/mongodb

服务器启动后,以管理员身份连接到服务器

> mongo <host:port> -u "root" -p "123456" --authenticationDatabase "admin"

连接后,创建普通用户.假设您的用户数据库名称是cd2.

> use cd2
> db.createUser({user: "cd2", pwd: "cd2", roles:["dbOwner"]})

如果您看到成功消息,请从mongo shell断开连接并重新连接新用户凭据.

> mongo <host:port>/cd2 -u "cd2" -p "cd2"

Answer 2

我们在MongoDB(3.2.4)上遇到这个问题的经验是它似乎是一个bug或一个没有文档的功能.如果您尝试从远程shell(而不是localhost)创建用户和角色,则会创建用户,但是一旦您离开shell,它们就会消失(它们是该会话的瞬态)并且不会真正持久化.

解决方案:只是尝试创建您的用户(最初在MongoDB上未启用身份验证)并直接在您的数据库服务器(localhost)的控制台上执行此操作.

如果您通过 shell 登录，请确保您在数据库“ admin ”下创建用户，而不是在自定义数据库下。在您的情况下，您切换到“c2d”。

这是我尝试过的（以“管理员”身份登录）

1.这个会起作用：

$ mongo -u admin -p --authenticationDatabase "admin"
> use admin
> db.createUser(
  {
    user: "user007",
    pwd: "YourP@ssw0rd",
    roles: [
       { role: "readWrite", db: "yourdb" },
    ]
  }
)

输出 1：

root@mongo-server:/# mongo -u admin -p --authenticationDatabase "admin"
MongoDB shell version v4.0.6
Enter password:
connecting to: mongodb://127.0.0.1:27017/?authSource=admin&gssapiServiceName=mongodb
MongoDB server version: 4.0.6

> db.createUser(

...     user: "user007",
...     pwd: "YourP@ssw0rd",
...     roles: [
...        { role: "readWrite", db: "yourdb" },
...     ]
...   }
... )
Successfully added user: {
        "user" : "user007",
        "roles" : [
                {
                        "role" : "readWrite",
                        "db" : "yourdb"
                }
        ]
}

root@mongo-server:/# mongo -u user007 -p YourP@ssw0rd

2. 这个会失败：

> db.createUser(
  {

    pwd: "YourP@ssw0rd",

Answer 4

--authenticationDatabase=admin如果 admin 是身份验证数据库，请在终端 mongo 命令中尝试选项。

例如：

代替： mongo 127.0.0.1:27017/c2d -u c2d -p c2d

用： mongo 127.0.0.1:27017/c2d -u c2d -p c2d --authenticationDatabase=admin
