yes I just started to understand MongoDB. Therefore I have installed MongoDB in the folder "Program files" yesterday and tryed to figure out, how to work with it.
Today I simply tryed to start it again. But something went wrong. To understand the beginning better I deinstalled MongoDB, deleted the MongoDB, data, log folders and have installed MongoDB again direct on c:/.
Started the server:
mongod --directoryperdb --dbpath c:\mongodb\data\db --logpath c:\mongodb\log\mongo.log --logappend --auth --rest --install
Started the service:
net start MongoDB
And the Mongo shell:
mongo
Now I try "show dbs" with the following result:
>show dbs

More I haven't done already. What can I do to show the dbs?
Of cource, I have tryed the learnings of the following post to, without success:
show dbs gives "Not Authorized to execute command" error
Looks like you are starting the db with --auth but not connecting with username/password. If you have not created any user then remove --auth and restart db. Then you will be able to connect.

I am trying to run some shell commands in mongo which is inside docker container.
docker exec -it mongodb_mock bash
It opens the mongo shell. but when I run any command in this it gives authentication error:

Please help.
EDIT: This db is created through mongoose/express, from another container.
first you need to authorize db with user, below is example command
use admin;
db.auth('admin','password');
then your able to run all querys. or start mongod without --auth parameter so you no need user authentication.
I am new to mongo db.
I just installed mongo DB on my MAC,
After watching this Youtube Video
https://www.youtube.com/watch?v=pWbMrx5rVBE&t=369s
In mongo shell, I entered show dbs and I get wired output.
Kindly help me to understand and solve this

After a couple of research, I found the solution and sharing all I learned so no new learner struggles like me.
My mistake :
I was staring mongodb using :
mongod --config "c:\MongoDB\Mongod.cfg"
and start mongo shell by just running
mongo
Starting Mongo DB and Shell
Then understood, what each command does :
|*| Start Mongo DB with default config :
mongod
|*| Start Mongo DB with config file :
mongod -f "c:\MongoDB\Mongods.cfg"
|Or|
mongod --config "c:\MongoDB\Mongod.cfg"
|O| Start Mongo DB with config flags :
mongod --dbpath "c:\mongodb\data\nameMdb" --logpath "c:\mongodb\log\nameMdbLog.log" --directoryperdb --logappend
So correspondingly we should use mongo also to start shell :
|*| Start Mongo shell with default config :
mongo
|*| Start Mongo shell with localhost config flags :
mongo --host localhost --port 28888
|*| Start Mongo shell with public config flags and user details :
mongo --username <user> --password <pass> --host <Host.IP.Adrs> --port 28888
|*| Creating Config File is explained here with example :
https://github.com/mongodb/mongo/blob/master/rpm/mongod.conf
I had a similar issue when configuring MongoDB for replication.
When I run the command below:
mongo
show dbs
I get the error:
> show dbs

Here's how I fixed it:
The issue was that I had enabled the replication feature in the /etc/mongod.conf file without initializing the replication, so MongoDB could not tell which replica was the primary replica or secondary replica.
All I had to do was to comment out the replication feature in the /etc/mongod.conf file since I was not yet ready to set up replication:
#replication
# replSetName: my-replica-set-name
After which I restarted the MongoDB server:
sudo systemctl restart mongod
This time the command ran fine.
I experienced this issue today, installing the latest version of MongoDB with Homebrew and then launching the mongo shell and entering the command "show dbs". I tested this multiple times and spent some time researching it. The symptoms match an issue that was reported here: https://jira.mongodb.org/browse/SERVER-20753 where the issue was described as building WiredTiger separately from MongoDB and using an out of date version of WiredTiger.
While this is not the case for what you and I have experienced (note that Homebrew is currently installing 3.4.9 and WiredTiger 2.9.2), I guessed that it could be a similar mismatch between WiredTiger and MongoDB, so I decided to try installing a different version.
I ended up installing the latest "dev" version using this Homebrew command:
brew install mongodb --devel
This installs MongoDB 3.5.13 and WiredTiger 3.0.0 which do not have the issue. Note that 3.4.9 was released the day you reported this issue and 3.5.13 was released the next day, although 3.4.9 is still the current community edition listed here: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/
In my case, the problem was replSet name.
I was changed my hostname at the Sharing preference and it was different with the previous installed replSet config's host name.
You can see the rs.config() in mongo shell like this.
"members" : [
{
"_id" : 0,
"host" : "MBA.local:27777",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}
],
See the host: section and change it by rs.config({object}) command in mongo shell,
or just add the line below at the /etc/hosts file.
127.0.0.1 MBA.local
I've got multiple issues with an application which I suspect are related to permissions on the database.
Everything seems locked down however and I can't complete basic commands such as show dbs in order to troubleshoot the problems further and "see" what I'm working with. I've been stuck on this for two days now and it's really frustrating.
I've tried this both from the online console and on local terminal, both with and without user credentials supplied at login:
Online Console

} at src/mongo/shell/mongo.js:47
Troubleshooting envars are correct:
me#my-computer:~$ oc env pods mongodb-1-vs19d --list
# pods mongodb-1-vs19d, container mongodb
MONGODB_USER=admin
MONGODB_PASSWORD=secret
MONGODB_DATABASE=users
MONGODB_ADMIN_PASSWORD=very-secret
The database was created from local terminal with:
oc new-app mongodb-persistent -p MONGODB_USER=admin,MONGODB_PASSWORD=secret,MONGODB_ADMIN_PASSWORD=very-secret
As per official docs:
https://docs.openshift.com/online/getting_started/beyond_the_basics.html#btb-provisioning-a-database
https://docs.openshift.com/online/using_images/db_images/mongodb.html#running-mongodb-commands-in-containers
It looks like you're trying to show dbs as user who has not been granted the needed role. You can try authenticating yourself as admin as follows:
mongo -u admin -p $MONGODB_ADMIN_PASSWORD admin
Then you should be able to show dbs, show users, use other databases and show users there, etc...
It's a bit confusing that your $MONGODB_USER is named admin - this regular user will have access to the $MONGODB_DATABASE. Another admin has been created by the used image most likely as well.
I know this is a very common question for MongoDB, but I really tried most of the answers, but could not solve this issue.
So I feel I'm missing something Somewhere
Here are the steps:
Downloaded latest version 3.03 of MongoDB.
Custom installed to f:\MEAN\MongoDB.
F:\MEAN>sc.exe create MongoDBSvc binPath= "\"F:\mean\mongodb

I have a problem removing records from a capped collection. DB is complaining that command doesn't exists.
There is a collection that is capped. I have verified by issuing isCapped().
I switch to a db that contains the collection.
Then I run
db.runCommand({ emptycapped: 'events'})
as a result I get :
{
"ok" : 0,
"errmsg" : "no such cmd: emptycapped",
"bad cmd" : {
"emptycapped" : "events"
}
}
Environment details :
MongoDB shell version: 2.2.0
Mongod Server version: 2.4.1 on Ubuntu 12.04
Any ideas what could be the possible cause ?
As Enrique Fueyo's commented:
In the docs (http://docs.mongodb.org/manual/reference/command/emptycapped) you can read that "...is not enabled by default. emptycapped must be enabled by using --setParameter enableTestCommands=1 on the mongod command line."
You need to start mongo with a command such this:
$ mongod --config /usr/local/etc/mongod.conf --setParameter enableTestCommands=1
