I have a MEAN droplet on digital ocean and I've found that when I run the mongo command I connect to test successfully and have access to my other databases, but if I try to run the mongod command I get the following message:
*********************************************************************
ERROR: dbpath (/data/db) does not exist.
Create this directory or give existing directory in --dbpath.
See http://dochub.mongodb.org/core/startingandstoppingmongo
*********************************************************************
How is this possible? I thought mongo was connecting to a specific instance of mongod.
I will create the /data/db folder, but I feel like I might just be ignoring another problem with setup configuration that has allowed this to happen.
/data/db will be the place you store your database data. After you created that folder, you can run mongod as normal.
The mongod is a command to start mongodb server. And mongo is a command line interface to make you community with mongodb server.
So you should start the server -> community with server.
I recently started the mongodb service on my windows machine, and it is running succesfully. Or at least I think it is, though I am not 100% sure and I don't know what port it is running on because all attempts to check the status have failed. When I try to run mongo.exe, I get the following error:
paul#PAUL_LAPTOP /c/program files/mongodb 2.6 standard/bin
$ mongo
MongoDB shell version: 2.6.3
connecting to: test
2014-08-11T03:36:15.802-0400 warning: Failed to connect to 127.0.0.1:27017, reas

refused it.
2014-08-11T03:36:15.808-0400 Error: couldn't connect to server 127.0.0.1:27017 (
127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed
Any ideas how I could check why this is happeing? One good first step would be checking the status of my mongo service, which I am not sure how to do.
Any help is greatly appreciated.
Thanks,
Paul
Have you gonbe through all the steps here: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/?
You need to run the mongod command to start mongodb, and you also have to define the path where mongodb shall store your database:
C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
When you typed in the mongod command, did you also give it a path? This is the step beforehand and this is usually the issue.
mongod --dbpath="put your path to where you want it to save the working area for your database here!! without these silly quotations marks I may also add!"
example: mongod --dbpath=C:/Users/Kyle-3/Desktop/DEV/dangerzonearea/test/mongodb
That is my path and don't forget if on windows to flip the slashes forward if you copied it or it won't work!
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
connection could be made because the target machine actively refused
it.
...
Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1),
connection attempt failed at src/mongo/shell/mongo.js:146 exception:

In the CMD where I running the mongod the output is:

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
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
I was running a Rails rake task overnight on my local machine in order to seed my Mongo collection. It had probably generated about 45,000 records before I received the following exception:
Operation failed with the following exception: connection closed
Failed to connect to a master node at localhost:27017
I am on a Mac OS X, so I attempted mongo and received the following:
Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84
exception: connect failed
So I ran mongod thinking that this would simply start up the process. It now appears to have indexed new collections, because all of them are empty. Did I overwrite them, or might they still exist somewhere?
I ran ls /data/db and I see myapp_development.0 and myapp_development.ns. Does that tell me anything?
Sounds like your MongoDB data directory was set to somewhere other than the default (/data/db). Restarting would likely have started mongod with the correct --dbpath.
For example, if you followed a MAMP install guide the suggestion may have been to put the data directory inside /Applications/MAMP/db/mongo.
You should be able to find the dbpath used by running the following command in the mongo JS shell:
db.adminCommand('getCmdLineOpts')
Look for a parsed setting for "dbpath".
