Mongodb not working in windows 32bit [duplicate] - php

Question

I am coming from riak and redis where I never had an issue with this services starting, or to interact.
This is a pervasive problem with mongo and am rather clueless. Restarting does not help.I am new to mongo.

Answer 1

Normally this caused because you didn't start mongod process before you try starting mongo shell.
Start mongod server
mongod
Open another terminal window
Start mongo shell
mongo

Answer 2

Resolved.
This problem could be solved by the below mentioned 4 steps
1) Remove .lock file
sudo rm /var/lib/mongodb/mongod.lock
2) repair the mongodb
mongod -–repair
3) start the mongod server
sudo service mongod start
4) start the mongo client
mongo

Answer 3

This method only works if you want to repair your data files without preserving the original files
To find where you dbpath resides- vim /etc/mongodb.conf
check for option dbpath=
(I have dbpath=/var/lib/mongodb)
Default: /data/db/
Typical locations include: /srv/mongodb, /var/lib/mongodb or /opt/mongodb .
Replace the /var/lib/mongodb with your dbpath
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --dbpath /var/lib/mongodb/ --repair
sudo mongod --dbpath /var/lib/mongodb/ --journal
(Make sure that you leave you terminal running in which you have run above lines,
dont press 'Ctrl+c' or quit it.)
Type the command to start mongo now in another window.
Hope this works for you !
for those who want to repair your data files while preserving the original files
mongo recover

Answer 4

This error is what you would see if the mongo shell was not able to talk to the mongod server.
This could be because the address was wrong (host or IP) or that it was not running. One thing to note is the log trace provided does not cover the "Fri Nov 9 16:44:06" of your mongo timestamp.
Can you:
Provide the command line arguments (if any) used to start your
mongod process
Provide the log file activity from the mongod startup as well as
logs during the mongo shell startup attempt?
Confirm that your mongod process is being started on the same
machine as the mongo shell?

Answer 5

I am a windows user and I installed MongoDB in November 2018 and I didn't wanted to setup data/db directories. But after few days, when I open, got an error message:
MongoDB shell version v4.0.4
connecting to: mongodb://127.0.0.1:27017
2018-12-05T20:42:40.108+0530 E QUERY [js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: No connection could be made because the target machine actively refused it. :
connect#src/mongo/shell/mongo.js:257:13
#(connect):1:6
exception: connect failed
Then I tried to fix using all of above answers and didn't worked. When I tried to run mongod it said
MongoDB starting : pid=12220 port=27017 dbpath=C:\data\db\ 64-bit host=bla
I tried to change the db path(to program files) through file system and also using cmd but those didnot worked.
Solution that worked for me is:
Opened the Task Manager (ctrl + shift + esc) -> Services tab and there was a MongoDB row with the status stopped. Then I right clicked and clicked start and everything working perfectly :).

Answer 6

MAC OS
Check status
brew services list
Something like:
Name Status User Plist
mongodb stopped
start it
brew services start mongodb
Try it again
mongo or mongo --port 27017

Answer 7

Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: No connection could be made because the target machine actively refused it.
This error caused because Mongo Server been closed
Simple Follow these steps
Open Task Manager
Go to >Services
Find MongoDB
Right click and select Start

Answer 8

In my case:
First I open config file
sudo vi /etc/mongodb.conf
Comment IP and Port like this
#bind_ip = 127.0.0.1
#port = 27017
Then restart mongodb
sudo service mongodb restart
sudo service mongod restart
Finally, it's work :D
finn#Finn ~ $ mongo
MongoDB shell version: 2.4.9
connecting to: test
> exit

Answer 9

A little to late with the answer but I've encountered the same issue
Following are the steps which helped me.
Go to C:\
Create "data" folder
In "data" create "db" folder
open terminal (CMD) -> go to EX:"c:\MongoDB\Server\3.4\bin"
type in mongod => this will start mongo server (leave it opened)
Run using a GUI, EX "robomongo"
Or
open new terminal (CMD) -> go to EX:"c:\MongoDB\Server\3.4\bin"
type in "mongo" command

Answer 10

Make sure that your mongo is running.
I fixed this problem by trying to repair the mongodb, there I found that the directory required for the db to run was not created. It shows this error
Type: mongod, it will show the error
exception in initAndListen: 29 Data directory /data/db not found., terminating
Error happen because dbpath /data/db/ (default config) does not exist. You need to create data folder and set permission for it.
Then I create a folder on my system by the command
sudo mkdir -p /data/db/
and
sudo chown id -u /data/db
then I run the mongo again and it worked.

Answer 11

I face same issue after searching a lot I solve this by following :
sudo service mongodb stop
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --repair --dbpath /var/lib/mongodb
sudo mongod --fork --logpath /var/lib/mongodb/mongodb.log --dbpath /var/lib/mongodb
sudo service mongodb start

Answer 12

If all the above solution does not work: go to service (start>search>services) and start mongodb service. Then, in a cmd prompt, after going to bin, type :/>mongo

Answer 13

To connect with mongo we have to first start 'mongod' services.
following output you can see :
$ mongod

After that open another terminal and just type 'mongo'.
Following is output you can see :

connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.2
Your issue solved :)

Answer 14

I also have the same problem then I got fixed by these two lines of code. Hope, it helps
systemctl start mongod
systemctl enable mongod

Answer 15

Start monogdb service using
sudo service mongod start
then from the new window or terminal start mongo client using
mongo

Answer 16

After exhausting lots and lots of sulotions, I did-
sudo brew services start mongodb-community rather than
sudo service mongod start and it worked.
So, first try
sudo brew services start mongodb-community
and then to start the mongo shell, do-
mongo

Answer 17

FOR MACOS
Check the status of the services:
brew services
If you have something like:
Name Status
mongodb-community error
So you can just to stop and restart the service like this:
brew services stop mongodb-community
brew services start mongodb-community

Answer 18

This was happening with me today and I resolved it in following way.
Machine: I'm using Windows 10 machine and downloaded the latest MongoDB - Community edition.
So, the problem was, I did not have C:\data\db created.
Without creating C:\data\db, I opened CMD terminal and started the database using mongod command at terminal
C:\YourInstallationPath\bin>mongod
And when I fired mongo command then I was getting the problem.
Twist, I created the necessary folders but still was getting the problem. And this is because mongo server was already running. To fix it, I fired up mongod command again, and it automatically referenced to C:\data\db.
Other users have suggested to add C:\data\db but did not talk about executing mongod again, which exactly solved my problem.

Answer 19

I had same problem to connect mongodb after install using brew on macOS.
The problem was also mongod.lock but before i had mongodb 3.6 installed and database directory was /usr/local/var/mongodb and it have old files and mongod.lock
Simple i moved my old database files to different folder and removed everything from /usr/local/var/mongodb
Then restarted :
brew services restart mongodb
And it's working fine now.

Answer 20

I was getting this error on ubuntu but you can try with the following command:
sudo service mongod start

Answer 21

You can try with following command:
sudo service mongod start

Answer 22

in my case in windows and ubuntu, i needed to create /data/db folder in root. In ubuntu, i needed one additional option; to give permissions for directory.
windows
mkdir c:/data/db
ubuntu:
sudo mkdir -p /data/db
sudo chmod 700 /data/db
then run
sudo service mongod start
check
sudo service mongod status
and then run
mongo

Answer 23

Remove mongod.lock file. And run "mongod -repair". uninstall/reinstall mongod service fixed that problem for me.
Thanks.

Answer 24

Another solution that resolved this same error for me, though this one might only be if you are accessing mongo (locally) via a SSH connection via a virtual machine (at least that's my setup), and may be a linux specific environment variable issue:
export LC_ALL=C
Also, I have had more success running mongo as a daemon service then with sudo service start, my understanding is this uses command line arguments rather then the config file so it likely is an issue with my config file:
mongod --fork --logpath /var/log/mongodb.log --auth --port 27017 --dbpath /var/lib/mongodb/admin

Answer 25

Create the folder C:data/db if it doesn't already exist on your computer. Turns out MongoDB requires the existence of this folder structure 'data/db' to run. I hope this helps someone.

Answer 26

The cause by me was the space - run this in the console:
df -h
or more specifically:
du -hs /var/lib/mongodb/
to check he disk usage. If it's ~ 99% - just clean up some space and try again!

Answer 27

First, go to c:\mongodb\bin> to turn on mongoDB, if you see in console that mongo is listening in port 27017, it is OK
If not, close console and create folder c:\data\db and start mongod again

Answer 28

if all the solution above doesn't work out perhaps then this might be one to help. Somewhere down the line you may have made connection to your local mongodb database via vagrant boxes.
vagrant up and then ssh into your vagrant machine in which you've made connection with mongodb (vagrant ssh vagrant_box_name)
comment out the bind_ip line from /etc/mongod.conf using # (sudo nano /etc/mongod.conf )
restart your mongodb daemon service (sudo service mongod restart)
voila...

Answer 29

OK, this may be strange. My error happened because my log grew exponentially and clogged up server space hence mongo didn't get enough space to store anything.
so I cleared the log
> /var/log/mongod.log

Answer 30

When we take taskbar manager, go to Service tab. There MongoDB status shows the stopped. Right click for start. Its will connect MongoDB server version.
for checking type "db".
db
test
It will work fine.
