Did you complete steps in terms of setting up and securing MongoDB as per the documentation ?

You mean I need type:

sudo vim /etc/mongod.conf

Then

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: true
#  engine:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1


# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

#security:
  authorization: enabled
#operationProfiling:

#replication:

#sharding:

## Enterprise-Only Options:

#auditLog:

#snmp:

Is these right?

@napishtim yes. Did you restart MongoDB after making those changes?

It causes Connection refused. How can I do for these?

Have you checked if mongo is running?

sudo systemctl status mongod

I had repaired securing MongoDB. But I can not verify the administrative user created earlier can connect

napishtim@napishtim-M14xR1:~$ mongo -u admin -p （myadminpassword） --authenticationDatabase=admin

@napishtim did you create the administrator account under the admin database or nodebb ? If under nodebb but not admin, then this won't work.

napishtim

@phenomlab
Of course I had created it.

phenomlab

@napishtim Ok - have you tried the password you believe you set in uppercase, or with variations ?

napishtim

@phenomlab My password consists of upper case letters, numbers and lower case letters.
