Mongodb: Failed to connect to 127.0.0.1:27017, rea

问题:

Here is my mongod.cfg file:

bind_ip = 127.0.0.1
dbpath = C:\mongodb\data\db
logpath = C:\mongodb\log\mongo-server.log
verbose=v

Here is my mongod service command:

mongod -f c:\mongodb\mongod.cfg --install

I have installed MongoDB about a week ago and it all worked fine, however today when I ran mongo command I got the following 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

How can I fix that? I use Windows 8.1

Solution:

I forgot to start mongodb service with this command:

net start mongodb

Improved solution:

1) Change directory to root drive C:\, and type the command below into an admin cmd prompt window,

C:\mongodb\bin\mongod.exe --config c:\mongodb\mongod.cfg --install

2) Then type net start MongoDB after which you should see the following message:

"The Mongo DB service was started successfully"

3) Then go to the control panel Start>Administrative Tools>Services, scroll down to MongoDB in the list of services and change start up type to automatic, if you so desire. Press OK.

4) Finally type C:\mongodb\bin\mongo.exe and you should be connected to the Mongo test DB.

This is how I solved it, You can follow step by step here:

MongoDB Steps:

• Download the latest 64-bit MSI version of MongoDB for Windows.

• Run the installer (.msi file)

• Add it to your PATH of environment variables. it Should be from:
  C:\Program Files\MongoDB\Server\3.0\bin

now Create a “\data\db” folder in C:/ which is used by mongodb to store all data. You should have this folder:

C:\data\db

Note: This is the default directory location expected by mongoDB, don’t create anywhere else

.

Finally, open command prompt and type:

>> mongod

You should see it asking for permissions (allow it) and then listen to a port. After that is done, open another command prompt, leaving the previous one running the server.

Type in the new command prompt

>> mongo

You should see it display the version and connect to a test database.

This proves successful install!=)

When you typed in the mongod command, did you also give it a path? This is usually the issue. You don't have to bother with the conf file. simply type

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/kyles2/Desktop/DEV/mongodb/data

That is my path and don't forget if on windows to flip the slashes forward if you copied it from the or it won't work!

回答3:

I was also faced the same issue with mongodb 2.6.

What solved my problem was I just run mongod --repair command

and then start mongod.exe

It's worked for me

回答4:

mongodb 2.6.8 on windows7 32bits you only need create a folder c:/data/db execute mongod, and execute mongo

回答5:

Point to your mongodb instalation e.g C:\Program Files\MongoDB\Serve\bin and run mongod.exe so you can open connection to 127.0.0.1:27017.

回答6:

Normal case, you need at least 3379 MB of disk space. If you do not have;

mongod.exe --smallfiles

This is not the only requirement. But this may be your problem.

回答7:

The problem is that I missed out 'db' folder for the dbpath in the command:

C:\mongodb\bin> mongod --directoryperdb --dbpath C:\mongodb\data\db --logpath C:\mongodb\log\mongodb.log --logappend -rest --install

回答8:

just create a folder

C:\data\db 

Run below commands in command prompt

C:\Program Files\MongoDB\Server\3.4\bin>mongod

Open another command prompt

C:\Program Files\MongoDB\Server\3.4\bin>mongo

回答9:

If it writes that you had not properly shut down or that mongod.lock is not empty , only delete mongod.lock from C:\data\db\ and it will start.

回答10:

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

回答11:

When This Error is Coming it is lack of the following

1)Setting the path to mongo db go to "C" Drive and the installation of Mongo db directory and then go to bin folder in the mongo and copy the path of it

c:/mongodb/server/3.2/bin/ and create a new environmental variable in system properties then name is path and value="c:/mongodb/server/3.2/bin/" here my version is 3.2

2)create a data directory for the data in C Drive c:/Data/twitter

3)start the server with **

c:/> mongod

check your port config if there is any error as the local port may be assigned to any other 4)start your Mongo database with

Mongo then your mongo db will start

then in your mongo database create a database

use DATABASE_NAME

for example:

use twitterdata

switched to db twitterdata

to check your current database

db

twitterdata

to get total databases

show dbs

I started mongod in cmd,It threw error like C:\data\db\ not found. Created folder then typed mongod opened another cmd typed mongo it worked.

回答13:

Here are the steps to solve this issue:

1. Just go to your MongoDB bin folder and run the mongod.exe file.
2. Navigate to your mongodb bin folder via Command prompt and start mongo by typing "mongo"

回答14:

Change file permission to 755 for the file:

/var/lib/mongodb/mongod.lock

回答15:

first you run the command mongod and check weather the port 27017 has started or not if yes then hit the command mongo....and database will start.

回答16:

The Port is not open. Thats why the machine refuses communication

回答17:

Try this, it worked for me.

mongod --storageEngine=mmpav1
