To set up a client connection:

The default installation allows only 127.0.0.1 IP connections.

The following records need to be modified/etc/mongodb.conf comments:

Open File:

$ sudo gedit/etc/mongodb.conf

Note Record:

#bind_ip = 0.0.0.0

A later version of MongoDB 2.6 Adds a user method, each library requires authorization to access:

https://docs.mongodb.org/manual/reference/method/db.createUser/

Use the Products
Db.createuser (
   {
     User: "Accountuser",
     pwd: "Password",
     roles: ["ReadWrite", " DbAdmin "]
   }
)

After installing the user in centos6.5 above the connection error, check the log mongodb.log:

AUTHENTICATIONFAILED:MONGODB-CR credentials missing in the user document

Very feeling the answer of this elder brother Vivek (Http://stackoverflow.com/users/2512718/vivek):

Http://stackoverflow.com/questions/29006887/mongodb-cr-authentication-failed

Go to MongoDB console and delete your current user & set Authschema version to 3 instead of 5, follow these commands In MONGO console-


Mongo
Use admin
Db.system.users.remove ({}) <== removing all users
Db.system.version.remove ({}) <== removing current version
Db.system.version.insert ({"_id": "Authschema", "CurrentVersion": 3})
Now restart the Mongod and create new user then it should work fine.


Note:use remove commands in test db only, if in production use Update.

Restart MongoDB and then use the following command to create a new user, as normal:

Db.createuser (
{
User: "username",
PWD: "passwd",
roles: ["ReadWrite", "DbAdmin"]
}
)

=========================

Db.createuser (
{
User: "11",
PWD: "11",
Roles: [{role: ' Useradminanydatabase ', db: ' admin '}]
}
)



Admin Library:

Db.grantrolestouser (
"Admin",
[
{role: "ReadWrite", DB: "Admin"},
{role: "Readanydatabase", DB: "Admin"},
]
)

General Library

Db.grantrolestouser (
"Admin",
[
{role: "ReadWrite", DB: "Test"},
{role: "ReadWrite", DB: "Files"},
]
)

To set up auto-start:
