When mongo3.03 enables auth authentication, there will be some problems that did not exist in previous versions, such as the addition of SCRAM-SHA-1 verification method to mongodb after 3.03.

The day before yesterday, I found that the newly built mongo development was not connected. I used the software to test if it was due to ip restrictions, and then it wasn't, but I noticed that there was an authentication option, one is SCRAM-SHA-1 and the other is mongodb-cr. I found out if it was due to authentication, so I looked at the new version of mongo3.03 and found that it was.

> db.system.users.find ()

{"_ id": "xxx.xxx", "user": "xxx", "db": "xxx", "credentials": {"SCRAM-SHA-1": {"iterationCount": 10000, "salt": "Ixxxxxxxxxxxx", "storedKey": "xxxxxxxxxxxxx", "serverKey": "xxxxxxxxxxxxxxxx"}}, "roles": [{"role": "userAdminAnyDatabase" "db": "xxxxxx"}]}

Close mongo

Cancel authentication and enable mongodb

> use admin

Switched to db admin

> var schema = db.system.version.findOne ({"_ id": "authSchema"})

> schema.currentVersion = 3

three

> db.system.version.save (schema)

WriteResult ({"nMatched": 1, "nUpserted": 0, "nModified": 1})

Then delete the previously created user

> use userdb

Switched to db userdb

> db.dropUser ("xxxxx")

True

Then create a user and then view that the user will display

{"_ id": "xxx.xxx", "user": "xxx", "db": "xxx", "credentials": {"MONGODB-CR": {"iterationCount": 10000, "salt": "Ixxxxxxxxxxxx", "storedKey": "xxxxxxxxxxxxx", "serverKey": "xxxxxxxxxxxxxxxx"}}, "roles": [{"role": "userAdminAnyDatabase" "db": "xxxxxx"}]}

Restart mongodb and you can use it.
