I am trying to run MongoDB in my Ubuntu machine using the following command but I am getting some error.
Command:
mongo
Error:

How can I resolve this issue and run MongoDB successfully?
Normally this is caused because you didn't start mongodb service before you try starting mongo shell. You can check for a system service status. If it is failing because of some error try to fix it and start the process. Below are few things that might help with it.
Check if mongodb service is up and running
sudo systemctl status mongodb
If not start mongodb service on your ubuntu machine
sudo systemctl start mongodb
Start mongo shell
mongo

I am trying to start a MERN app, I have installed mongo and any relevant things. But when I run mongo in my terminal the following appears.
I have looked across the board but the solutions do not help me. I am also running on Ubuntu 20.04.
MongoDB shell version v4.4.3
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
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 :: Connection refused :
connect#src/mongo/shell/mongo.js:374:17
#(connect):2:6
exception: connect failed
exiting with code 1
Fixed the issue by running
$ sudo rm -rf /tmp/mongodb-27017.sock
$ sudo service mongod start
Try to start the MongoDB server first running mongod command or from task manager>services> MongoDB server> right-click and start it

I have this mongo.zip installed in my win 10.
I have set the environment path with bin.
Somehow whenever I start command line,
my mongo cannot start without mongod first.
C:\Users\asus>mongo
MongoDB shell version v4.4.1
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
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:374:17
#(connect):2:6
exception: connect failed
exiting with code 1
but if I run mongod before mongo, mongo is running perfectly.
So, my question is: how do I running mongo without mongod locally.
PS. my compass is running and can connect to AWS cloud.
Please provide pictures if you can.
Thank you!
I think you, first of all, you have to know about the difference between them.
Mongod is the process of MongoDB.
Mongo is a shell. You can use it to connect and run any mongo command on any MongoDB.
So, your error means;
You are trying to connect your own MongoDB with typed mongo, because the default -host parameter is localhost. But your mongod process is not running. So you have to start it.
connecting to: mongodb://127.0.0.1:27017
127.0.0.1:27017 equals localhost.
If you have MongoDB (mongod process) on AWS. You should connect with below command
mongo --host mongodb0.example.com:28015
Failure to connect to mongodb after VM instance is reset.I get the following error
"Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused"
tried the following, but did not work
$ sudo service mongodb start
$ sudo mongod --repair
It seems like your MongoDB service is not set to to start automatically on server's reboot. You will need to either reinstall the mongodb or set the service to start on reboot by using sudo systemctl enable mongodb
I have issue with Mongo DB start up in ubuntu 14.04 64 bit,its working fine when i installed first time but suddenly from now when i type mongo in ubuntu terminal its showing error:
MongoDB shell version: 3.0.7

I tried many solution
i.e
1.deleting lock files, and restart mongo,
2.Change bind ip to 0.0.0.0 in mongod.conf
but my issue still not resolved.
Try to execute the following command to grep process id of mongod to determine if mongo service is running or not
pgrep mongod
If process id exists then please follow the steps as mentioned below
(a) Kill existing mongod process using following command
sudo kill -9 [process_id]
(b) Start mongod process using
sudo mongod --noauth --dbpath /var/lib/mongodb
I installed mongodb from this link
When i entermongo in console I got error
root#512son:~# mongo
MongoDB shell version: 2.6.9
connecting to: test

I searched this problem on internet and i tried:
sudo rm /var/lib/mongodb/mongod.lock
mongod --repair
If i enter mongod in terminal Mongodb work fine but when i close terminal mongodb is closing
I reinstall two times but my problem not fixed
You need to run MongoDB in the background. I mean start mongod as daemon using --fork
