You can kill the previous mongod instance and start the new one.
To kill the previous mongod instance, first search for a list of tasks running on your machine by typing,
sudo lsof -iTCP -sTCP:LISTEN -n -P
Search for mongod COMMAND and its PID and type,
sudo kill <mongo_command_pid>
Now start your mongod instance by typing,
mongod
You can see MongoDB running successfully.
You already have a process running in the port 27017 which is used by mongodb. So either you need to stop the process in that port or try with different port number.
Try mongod --port 27018
You can change the port number of your choice.
EDIT:
You can also just stop all the running instances of mongo server using
sudo killall mongod as mentioned by #Dassi Orleando in the comments.
And run mongod
Summary other(#Tony Roczz, #Balasubramani M) answer to here:
Root Cause
error: Failed to set up listener: SocketException: Address already in use
means:
previously have run mongodb
probably use default port 27017
Solution
(most case) kill and restart mongod
kill mongod
two method:
use killall
killall mongod
kill by PID
find mongod PID
method 1: ps aux | grep mongod
output can see like this: limao 425 ... /usr/local/opt/mongodb-community/bin/mongod --config /usr/local/etc/mongod.conf
method 2: lsof -iTCP -sTCP:LISTEN -n -P
output can see like this: mongod 425 limao .. TCP 127.0.0.1:27017 (LISTEN)
kill by PID: kill -9 425
re-start mongod
most case: mongod
some special case
brew services start mongodb-community
for install community version in Mac by: brew install mongodb-community
(for some people) run with another port
run with another port: mongod --port 27018
only for those want to run multiple mongod server same time
Additional Note
which port the running mongodb is using?
lsof -iTCP -sTCP:LISTEN -n -P
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mongod 425 limao 10u IPv4 0xab744305e75263cf 0t0 TCP 127.0.0.1:27017 (LISTEN)
can see 27017 is current running mongodb port.
how to check / make sure mongod is running
check mongod status:
ps aux | grep mongod
output can see mongod service
brew services list
if installed by brew and start by brew
if you're using mongodb version 4.*
in default settings, there should be a "db" folder "/data/db" having the necessary permission.
to check it the MongoDB service started
brew services list
if not then run
brew services start mongodb
run mongo instead of mongod
I solved it pasting the command below into the command line in order to close mongo's server.
sudo pkill -f mongod
"sudo" (Super User Do) runs the command admin permissions, so it will ask you for your user password
First, shutdown the running server using:
mongod --shutdown
Then run:
sudo mongod
After running this commands below:
sudo lsof -iTCP -sTCP:LISTEN -n -P
Search for mongod COMMAND and its PID and type,
sudo kill <mongo_command_pid>
And restarting mongod, it still fails with the same error "SocketException: Address already in use MONGODB".
Server was restarted yesterday and then this happened.
Just this single command
sudo pkill -f mongod
Make Sure the error is of the port , if using macos catalina there is a reported issue for ~/data/db which also causes this.
If your mongod process is already down, just remove the .sock file in /tmp:
My mongod is already down, so does not appears in:
lsof -iTCP -sTCP:LISTEN -n -P
The error was:
[root#ol7db19c1 ~]# mongod -f /etc/csrs_2.conf
about to fork child process, waiting until server is ready for connections.
forked process: 6721
ERROR: child process failed, exited with error number 48
To see additional information in this output, start without the "--fork" option.
In the log file (/var/mongodb/db/csrs2.log):
2020-07-05T16:03:59.354-0300 E STORAGE [initandlisten] Failed to set up listener: SocketException: Address already in use
So, find for the socket locking:
ls -ltra /tmp|grep .sock
And just remove it (do it with caution in production environment):
rm -f mongodb-26002.sock
G-luck!
This may sound obvious but you should check if mongodb is already running.
So instead of first starting the the DB by running:
sudo mongod
Try directly running:
mongo
I am trying to start MongoDB but the terminal returns the following error:

I am using Laravel Valet if that matters.
It seems like you have already a process running on the port where you want to start mongodb:
listen(): bind() failed Address already in use for socket: 0.0.0.0:27017
2017-02-06T16:26:27.038+0000 E NETWORK [initandlisten] addr already in use
you could try to kill the process that runs on that port with this command:
sudo kill sudo lsof -t -i:27017
or define another port for mongodb if you have another program using that port.
to run mongodb on a port other than its default port (27017) use the --port 27018 argument when starting mongodb from the terminal
If you are using mac then you can simply kill the process running on port 27017 which is mongodb process in most cases.
Simply run the command.
npx kill-port 27017
After that you can run the mongod command as you normally do.
Or if you are using windows follow these steps
Run command line as Admin
netstat -ano | findstr :27017
you will get pid in the end that is the process id to kill
taskkill /PID <typeyourPIDhere> /F
after successful termination of process you can run mongod as you usually do!
Enjoy!
This has worked for me
Initially i was facing various issues, like when i tried to start the server by using:
sudo mongod
then i changed port for mongodb
sudo mongod --port 27018
Now mongod server is running tentatively
sudo mongod
Basically you just need to force quit the mongo, you can do this just by typing
sudo pkill -f mongod
and now you can start the server again with
mongod
For me the kill process did not work. Probably because my mongo instance was running on AWS. So, what I did was log onto a mongo shell. (This was possible as mongo instance is running) And switched to the admin DB thru 'use admin' and did 'db.shutdownServer()'. And that shut down the server cleanly
use admin
db.shutdownServer()
I had the same issue (MongoDB failed to start with exit code 48) after a reboot, as it could not bind to the given IP.
It turned out, that the mongod systemctl unit file was configured to launch the mongod service after the network.target. I changed this to network-online.target and it seems to work.
1.And if the mongod show error (shutting down with code 48) that
means the port is being already use so you can do two things
1.a Either you change the port of mongod by specifying port
number
mongod --dbpath /System/Volumes/Data/data/db (path of db) —port 27018
1.b Or You can kill the process at that port by finding
the process by
sudo lsof -i :27017
and then kill by command
kill -9 <PID>
2.Starting mongo db using brew services run mongodb-community
3.Type mongod or mongod --dbpath /System/Volumes/Data/data/db(path)
How I solved my issue?
I don't know the actual reason for this error and its solution but I deleted mongodb database folders C:\data\db and restarted my PC.
2017-02-06T16:26:27.038+0000 E NETWORK [initandlisten] listen(): bind() failed Address already in use for socket: 0.0.0.0:27017.
It means the server 27017 is already in use.
You can try mongod --dbpath /System/Volumes/Data/data/db --port 27018.
Or
You can first stop the mongod by sudo pkill -f mongod.
Then restart the server by mongod --dbpath /System/Volumes/Data/data/db
In some cases we may be unaware of the process id where we have initiated mongodb , and we are not able to track it, as we might have forgot to shut it down in such cases:
step 1: first of all try to know the process id where it is being established, and
to know that, type below code in terminal:
lsof -i | grep 27017
Once you type the above code, you will be able to see process id's using your mongodb server:
enter image description here
As you can see in the above picture, there you can find that "9663" is the process id where your mongodb server is active.
Step 2: Now we need to kill this process, by typing the command:
kill <pid>
In the above code pid stands for process id, as shown in the above image the process id looks similar to that of "9336".
Step 3: Now we have successfully killed the process and then we are good to start
the server of mongodb using the command:
mongod
Now you are good to go!
I've installed MongoDB and I've found some unlogical things and I hope someone will answer me:
When I execute "mongo" I get logged into shell
When I execute "mongodb" I get the following errors:

What is the difference between two terminal commands: mongo as a first, and mongodb as a second?
MongoDB is great because my project is schema-less but it's always a horrible experience to configure it, create roles, authorization etc.
Thanks.
mongod is the server, to which requests to connect database are passed for example.
In above error, it shows that port address 27017 is in use. It means your mongod is already runnning. You just need to run command 'mongo' to access the Mongodb shell.
There is another possibility that some other process is running on port 27017
netstat -n | grep 27017 to check if process is running and kill -9 $(lsof -ti:27017)'
To use any database service, you have to start the database Server and same is the case with mongodb, the command mongod is used to start the MongoDB Server on your local machine or server.
In your question you have asked for the command mongodb that's not correct you need to run command mongod, 'b' is not the part of this command.
When you run the mongod, it starts your mongodb server on default
port 27017.
Then you open another terminal and use the command mongo to enter
into the mongo shell and perform your database operations.
The difference between the both commands is that mongod starts the
mongodb server and mongo allows you to enter into mongo shell to
perform further database operations.
Also, when you install mongodb, you have an option to install it as a service. Installing mongodb as a service starts the mongodb server in background when you boot your system.
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.

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
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

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
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?
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

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 :).
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

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

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

Your issue solved :)
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
Start monogdb service using
sudo service mongod start
then from the new window or terminal start mongo client using
mongo
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
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
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.
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.
I was getting this error on ubuntu but you can try with the following command:
sudo service mongod start
You can try with following command:
sudo service mongod start
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
Remove mongod.lock file. And run "mongod -repair". uninstall/reinstall mongod service fixed that problem for me.
Thanks.
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
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.
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!
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
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...
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
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.
