Mongo is unable to start - mongodb

I'm trying to start mongo uin windows10 by type: mongo in cmd.
I am getting this error:
C:\Users\Itzik>mongo
MongoDB shell version v3.4.1
connecting to: mongodb://127.0.0.1:27017

I have opened port 27017 in the firewall,
and restart mongo's services
and it still dont work.
what could it be?

Have you started the server? Mongodb follows a server-client architecture. mongo is the client, but before it is started you need to start mongod, which is the server.
If you haven't, start the server in advance in a different console:
mongod --dbpath "c:\data"
replacing c:\data by any folder where you want to store your data (you need to create the folder in advance).
If mongod is not in the path look in the installation path, it should be something like C:\mongodb\bin\mongod.exe.
When the server says something like 'waiting for connections', then you can go to another console and type mongo to start the client.

In C:\Program Files\MongoDB\ you might not have permission to create file/folder for your user. And mongo installer cannot create it because of lack of Administrative permission for your user.
So in C:\Program Files\MongoDB:
Create a folder named data
Create a folder named db inside the folder data
Now right click on the data folder and choose properties
Click security tab and select your user there
Click the Full control select box
Click ok, ok, ok ...
important! if you don't have the path "C:\Program Files\MongoDB\Server\3.4\bin" set in environment variable, please set it.
Now go to shell and type : mongod --dbpath "C:\Program Files\MongoDB\data\db"
That's it :)

First start the server.
Goto your installation path. Mine was in "Program Files/Mongodb/server/bin"
You will find a "mongod.exe" application.
However, the server will look for "C:/data" folder for all the databases.
So create the "C:/data" folder.
Now start the mongod.exe using command prompt.
>>mongod
After this you may start the client
>>mongo
This worked out for me.

Open the terminal as Administrator.
(You can simply do this by searching cmd in start and then right click and select "Run as administrator")
Go to bin directory of your MongoDB folder.
cd C:\Program Files\MongoDB\Server\3.4\bin
Type following command to start mongodb server :
mongod --dbpath "C:\Program Files\MongoDB\Server\3.4\bin\Data"
now, server will be waiting for connections.
Open a new command prompt(again as Administrator)
Go to bin directory.
cd C:\Program Files\MongoDB\Server\3.4\bin
Type following command:
mongo
This will show you a prompt of mongodb :
>
Thanks.

if u install by brew (on osx)
first run sudo mkdir /data/db
start mondoDB Daemon by typing mongod (leave it open) and then
run mongo by typing mongo in new terminal tab

I also have faced the same problem.
First i have typed mongodb in my command prompt ,It displays "waiting for connection on 27017" that means it is working.
Then i type mongo in another Command prompt Window then above error occurred.
I was having both .dll files in my xampp\php\ext folder.
(php_mongo.dll and php_mongodb.dll)
I deleted Php_mongodb.dll and also it's extension from php.ini file.
Again restart command prompt,Type mongod and then mongo
Now working correctly.

First set the path in Enviroment Variables, C:\Program Files\MongoDB\Server\3.6\bin
after that use bellow command
C:\>mkdir data
C:\>cd data
C:\data>mkdir db
C:\data\db>
Then go to bin directory and select mongod.exe or use mongod. Without closing previous cmd
open a new cmd and start the client using mongo
Now it will work.

This issue is resolved by creating a data directory
Then move to the bin folder of mongodb or setting path information in environment variables
Then you can enter the following command,
mongod --dbpath 'path of the data folder including data directory name'
Eg: mongod --dbpath c:\users\codemaker\data

getting error while connecting to mongo.exe [duplicate]

I'm trying to run Mongo from the Command-Line:
What's wrong? (I've IIS on localhost:80). And Apache on port 8080. Are there any issues
with this?
C:\MONGO\Project1\mongo\bin>mongo --port 27017
MongoDB shell version: 2.0.3
connecting to: 127.0.0.1:27017/test
Sat Mar 10 16:16:45 Error: couldn't connect to server 127.0.0.1:27017 shell/mong
o.js:86
exception: connect failed
I found that when I got this error it wasn't because I didn't have my default db path set up. It was because I was trying to run mongo.exe before running mongod.exe.
Did you create the default db path?
It defaults to "/data/db directory (or c:\data\db on Windows)"
Source: http://www.mongodb.org/display/DOCS/Starting+and+Stopping+Mongo
As Admin, create directory:
mkdir c:\mongo\data\db
As Admin, install service:
.\mongod.exe --install --logpath c:\mongo\logs --logappend --bind_ip 127.0.0.1 --dbpath c:\mongo\data\db --directoryperdb
Start MongoDB:
net start MongoDB
Start Mongo Shell:
c:\mongo\bin\mongo.exe
Follow
Create default db folder.
c:\data\db
and also log folder
c:\data\log\mongo.log
or use following commands in command-prompt
mkdir c:\data\log
mkdir c:\data\db
Create config file in bin folder of mongo (or you may in save your desired destination).
Add following in text file named "mongod" and save it as
mongod.cfg
dbpath=c:\data\db
logpath=c:\data\log\mongo.log
or use following commands in command-prompt
echo dbpath=c:\data\db>> "mongod.cfg"
echo logpath=c:\data\log\mongo.log>> "mongod.cfg"
Now open command-prompt (administrator) and run the following command to start mongo server
mongod
Open another command-prompt (don't close 1st prompt) and run client command:
mongo
Hope this will help or you have done this already.
The error occurs when trying to run mongo.exe WITHOUT having executed mongod.exe.
The following batch script solved the problem:
#echo off
cd C:\mongodb\bin\
start mongod.exe
start mongo.exe
exit
If you are getting these type of errors when running mongod from command line or running mongodb server,
then follow these steps,
Create db and log directories in C: drive
C:/data/db and C:data/log
Create an empty log file in log dir named mongo.log
Run mongod from command line to run the mongodb server or create a batch file on desktop which can run the mongod.exe file from your mongodb installation direction. That way you just have to click the batch file from your desktop and mongodb will start.
If you have 32-bit system, try using --journal with mongod command.
Create default db folder.
c:\data\db
and also log folder
c:\data\log\mongo.log
or use following commands in command-prompt
mkdir c:\data\log
mkdir c:\data\db
you can use below command,
mongod --dbpath=D:\home\mongodata
where D:\home\mongodata is the data storage path
Go to C:\Program Files\MongoDB\Server\3.4\bin using cmd and
write mongod.
Open another cmd by right click and run as admin point to your
monogodb installed directory as mentioned above and then just like
write this mongo.exe
After that, write db.test.save({Field:'Hello mongodb'}) this command
will insert a field having name Field and value is Hello
mongodb.
After, check the record db.test.find() and press enter you will find
the record that you have recently entered.
Steps to start a certain local MongoDB instance and to connect to in from NodeJS app:
Create mongod.cfg for a new database using the path C:\Program Files\MongoDB\Server\4.0\mongod.cfg with the content
systemLog:
destination: file
path: C:\Program Files\MongoDB\Server\4.0\log\mongod.log
storage:
dbPath: C:\Program Files\MongoDB\Server\4.0\data\db
Install mongoDB database by running
mongod.exe --config "C:\Program Files\MongoDB\Server\4.0\mongod.cfg" --install
Run a particular mongoDB database
mongod.exe --config "C:\Program Files\MongoDB\Server\4.0\mongod.cfg"
Run mongoDB service
mongo 127.0.0.1:27017/db
and !see mongoDB actual connection string to coonect to the service from NodeJS app

Unable to connect MongoDb on Windows

I have installed mongodb.msi(installed in C:\Program Files\MongoDB\Server\3.0\bin) and C:\data\db is created. But whenever I try to connect to mongodb it results in connection fail. From command promt, first I run mongod.exe and then mongo.exe and it results in this error:
/bin directory need to be added in system variable PATH

MongoDB on a Windows 7 machine: No connection could be made

After I have started Mongo using mongod.exe on a Windows 7 machine, I tried to start the mongo shell that failed with the error:
Failed to connect to 127.0.0.1:27017, reason: errno:10061 No

Any suggestion how to fix this issue?
I got the same error and fixed it with:
1) mkdir c:\data
2) cd data
3) mongod -dbpath .
4) Now in another command window I was able to connect from my client using the mongo command.
I got this problem. What fixed mine is:
Suppose you have a dir: "C:\mongo_databse"
Open Command Prompt and type (suppose you haved added the Mongo bin directory to PATH): mongod --dbpath=C:/mongo_database.
There will be some log to the command prompt.
Now open ANOTHER command prompt then type in mongo then it works.
What solved my issue was creating a file startmongo.conf that sets the bind_ip to 127.0.0.1 . After that, I just created a *.bat to start the mongo using something like:
mongod --config c:\mongodb\bin\startmongo.conf
More details could be seem at this post .
I assume your mongo.config file to be located inside the mongodb folder in the same level to the bin directory.The contents of the mongo.config file are:
dbpath=C:\mongodb\data
logpath=C:\mongodb\log\mongo.log
diaglog=3
don't forget to create the data folder and log folder in the same level of bin directory inside log folder create the mongo.log empty file.
Point your command prompt to C:\mongodb\bin wherever your mongo db bin folder is located.
create the mongo db service in windows typing
mongod.exe --storageEngine=mmapv1 --config=../mongo.config
from now unwards you can start the mongo db service as
net start mongodb
finally you can connect to the mongo db server from the mongo db client typing
mongo.exe
once you have gone successfully from step 1 to step 3 from the next time on wards you only need the step 4 and 5.to start the service and to connect.
it prompted me like this
1)So, i created a path
C:\data\db
2)Now run
mongod in your terminal
it solved me issue!
I got this error beacuse of not sufficient space in the disk.
Check your mongo log.
I was getting a similar error when I was trying to start my mongo db via cmd. However the difference was I had a config file which has the path to the db and log folders and wanted to use the same. I was using mongo few days back and it was running fine but when I started using it again today it was giving me the error :
2015-05-27T10:33:22.820-0400 I CONTROL Hotfix KB2731284 or later update is installed, no need to zero-out data files

Here's how I fixed it :
Open cmd as admin and navigate to the bin folder of your MongoDB and type : mongod --config <path to your config file> --install
Now start your mongo db service : net start mongodb
you should get a message which says : The MongoDB service was started successfully.
close this command prompt and open another one as admin, navigate to the bin folder once again and type mongo
This will connect you to the mongodb test.
Press ctrl+c anytime to exit.
Hope this helps.
In Windows 10:
Executing below command restarts mongodb service (as administrator), required if there is a system restart after mongodb installation.
net start mongodb
Also make sure to check, if there is a MongoDBInstallation folder/data and /data/db folder created, same can be obtained at MongoDBInstallation\bin\mongod.cfg
mongod --dbpath=c:\MongoDBInstallation\data\db
Open task manager, click on the services tabs on the top. From the list right click on mongoDB then click start.
I had a very similar experience to #user1501382, but tweaked everything slightly in accordance with the documentation
1) cd c: //changes to C drive
2) mkdir data //creates directory data
3) cd data
4) mkdir db //creates directory db
5) cd db //changes directory so that you are in c:/data/db
6) run mongod -dbpath
7) close this terminal, open a new one and run mongod
for mongodb 3.0 versions use "--smallfiles".
e.g:-
mongod --dbpath="C:\Program Files\MongoDB\Server\3.0" --logpath="C:\Program Files\MongoDB\Server\3.0\data\log.txt" --smallfiles --install
I am not sure if there is a better way to run it.
For me, I use these settings to create a directory and to a determinate new path for the MongoDB.
The important thing for me is that I miss to run it as a server (mongod) and after that into another terminal I type mongo which provide me an option to use the database.
I hope this could help someone.
I found my answer on this page. https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-mongo-app?view=aspnetcore-3.1&tabs=visual-studio
So, first, make a folder for your data; then, open one command shell
mongod --dbpath <data_directory_path>
then, open another shell, do whatever you want to do. You can see in MongoDB Compass, there are collections if you had one before.
I tried the above answer
, and it worked, but had a very important problem: My previous collections were lost in another mongoDB data folder which I didn't know where they are and how to get them back.
Before I run in to this mongo error, I was running mongo with no problem. When my windows10 boot files got corrupted and My computer went into blue screen, mongo ran into this error. So I just tried to retrieve the previous condition which I just was running mongo in one terminal and not mongod in another, so
I repaired mongoDB with it's installation exe file, and now everything is ok.
This is my mongoDB specs: mongodb-win32-x86_64-2012plus-4.2.1
Hope this help you too.
Just type mongod in one command prompt and then run mongo in another.
Simply follow the following steps mostly your problem will be solved(Windows 10)
services->mongodb->change auto to run
you can go to services>>Mongo DB server .. right click and press start . This worked for me
By simple step ,I was resolve this problem
first step - make a New folder in C-drive in PC with name - "data"
second step- now open this "data" folder
Third step - Inside the "data" folder, again make a new "db" folder
Note - Just leave it this both folder empty, no need to add any content inside this,
and run "mongo" and "mongod" in PowerShell of your PC.
I got the same error, and this is how I resolved it,
follow the below steps:-
Open mongod.cfg file
Add the bindIpAll: true tag in the
net (Network Interfaces) section
restart the mongoDB services.
# network interfaces
net:
port: 27017
bindIpAll: true
#bindIp: 127.0.0.1

connecting to test mongoDB is failed

I am new in mongoDB
I have tried to install mongoDB on win 8 - 32 bit
I followed "The Definitive Guide To MongoDB 2010" by Apress.
I pasted the file in C drive root "mongodb-win32-i386-2.4.6"
Then I created nested folder in C
data/db ,
As the book was mentioned.
After that I opened cmd :
cd C:\ mongodb-win32-i386-2.4.6
cd bin\
up to here everything went well
then I tried to connect to mongo
but :
mongo
couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145
exception: connect failed
occured.
Where is problem?
Thanks in advance
First Thing is
MongoDB is almost always run as a network server that clients can connect to and
perform operations on so
create a folder data and in that db folder i.e., c:\data\db
First we need to start the server with the command mongod.exe avial in your bin folder
like C:\mongodb-win32-i386-2.4.6\bin\mongod.exe
Run the mongo.exe avail in the bin folder like C:\mongodb-win32-i386-2.4.6\bin\mongo.exe
Know How to stop the mongod.exe
from the client we need to issue these commands
use admin
db.shutdownServer()
then automatically mongod will shut and you need to quit from client with exit command
HAVE A NICE DAY WITH MONGO
The database itself is an executable called mongod.exe (mongoDB daemon). First you need to start this one. When it is running, you can use mongo.exe (mongoDB shell) to connect to it and issue commands.
For more information, read the article "Install MongoDB on Windows" from the official manual.
i have tried the binary files from https://www.mongodb.org/dl/win32/i386
After installing above binary file please go to bin directory (C:\Program Files\MongoDB\Server\3.2\bin -> default installation directory) and run following command
mongod.exe --journal --storageEngine=mmapv1 --dbpath c:\data\db
Note:make sure that you have already created the c:\data\db directory
Also if you need a GUI interface for mongodb, you can use Mongobooster

Unable to start mongodb

I'm trying to install mongodb on my window 7 machine. When trying to start it by using the mongod command I get this error. dbpath (\data\db) does not exist. I followed the steps ath the tutorial. All the folders exist C:\mongodb\log, C:\mongodb\data and C:\mongodb\data\db .
The default path is c:\data\db. You are trying to use c:\mongodb\data\db.
This means you have to use the option --dbpath c:\mongodb\data\db for mongod command.
By default, when we start the mongodb, it looks for the folder /data/db (on Mac/Linux) or C:\data\db (on windows)...however, during the installation it doesn't create this folder, so when when we run mongodb for the first time, it fails with the error that it can't find C:\data\db folder. The solution is to manually create C:\data\db folder and then start mongodb. This error can be totally avoided if the mongodb installer can just give an option to choose this folder path and then create it as part of mongodb installation itself.
In windows you might not have permission for your user. And mongo installer could not create it because of lack of Administrative permission for your user.
So in C:\Program Files\MongoDB:
Create a folder named data
Create a folder named db inside the folder data
Now right click on the data folder and choose properties
Click security tab and select your user there
Click the Full control select box
Click ok, ok, ok ...
important! if you don't have the path "C:\Program Files\MongoDB\Server\3.4\bin" set in environment variable, please set it.
Now go to shell and type : mongod --dbpath "C:\Program Files\MongoDB\data\db"
That's it :)
Try to use 2 command Prompts (CMD) at the same time.
First CMD, use the command:
mongod (or mongod --dbpath C:\mongodb\data)
Second CMD, use the command:
mongo
The second will connect in the database. Do not close the first.
