Enable authentication

Mongod boot is not enabled by default, you need to specify –auth boot. or set the Security.authorization to "enabled" in the configuration file.

Create user

db.createUser(user, writeConcern)

• Document http://docs.mongodb.org/manual/reference/method/db.createUser/#db. CreateUser

User format

"<name>",  "<cleartext password="">",  customData: {  },  roles: [    "<role>""<database>""<role>",    ...  ]}

Writeconcern:

For example {w: "Majority", J:true, wtimeout:5000}

W Options: The agreed values are 1, 0, values greater than 1, "majority", "j" option: Ensure that the Mongod instance writes data to the journal (log) on the disk, which ensures that no data is lost outside of the mongd. Set true to enable.

Wtimeout: Specifies a time limit, in milliseconds. The wtimeout is only suitable for w values greater than 1.

Built-in Roles (built-in role):

• Database user role: Read, readWrite;
• Database management roles: DbAdmin, Dbowner, useradmin;
• Cluster Management role: Clusteradmin, Clustermanager, Clustermonitor, Hostmanager;
• Backup recovery role: backups, restore;
• All database roles: Readanydatabase, Readwriteanydatabase, Useradminanydatabase, dbadminanydatabase
• Super User role: Root
  There are also several roles that indirectly or directly provide access to system super users (Dbowner, Useradmin, Useradminanydatabase)
• Internal role: __system
