I'm using homebrew to initialize mongodb as it follows:
brew services start mongodb-community#5.0
It starts successfully
==> Successfully started mongodb-community (label: homebrew.mxcl.mongodb-community)
However, when I type mongoto run mongodb, I keep getting connection refused:
MongoDB shell version v5.0.2
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:372:17
#(connect):2:6
exception: connect failed
exiting with code 1
So I typed brew services list to check if the mongoDB is up, and it seems it started with an error status:
Name

Plist
mongodb-community

/opt/homebrew/opt/mongodb-community/...
check the following.
if you are using M1 based MacOS then install mongo db (and brew) with Rosetta.
check the IP binding on mongo config
(/usr/local/etc/mongod.conf or /opt/homebrew/etc/mongod.conf)
verify the connection string URI format - Mongo docs - connection-string-uri-format

I have Robo 3T-1.3 installed on my ubuntu 16.4 LTS.
It is showing me the following error:
`Cannot connect to the MongoDB at localhost:27017.
Error:
Network is unreachable. Reason: couldn't connect to server localhost:27017, connection attempt failed: SocketException: Error connecting to localhost:27017 (127.0.0.1:27017) :: caused by :: Connection refused`
How to solve it?
Firstly check your mongo status via this command.
sudo systemctl status mongod
OR
You can follow this link.

Your using mongodb as command to start MongoDB but it should be mongod
To start MongoDB Server, run mongod.exe. Using below command,
mongod --dbpath="<DATABASE DIRECTORY>"
Then you can connect with MongoDB, Using command mongo
Default path MongoDB on Windows at C:\Program Files\MongoDB\Server\4.0\bin\mongod.exe
I have been trying to install Mongodb but it keeps failing midway. When the download is complete, installation fails with a connection error:
MongoDB shell version v3.6.3

What I've tried:
1. Changing the port:
mongo --port 4332
but it doesn't connect still:
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:4332/

Reinstalling the DB shows up as complete but I still can't start it. Check out the screenshot
Checking for any config files in /etc/mongo* or /var/lib/: there is none.
Note: There's no mongod service available too.
the installation seem to have worked, but the mongod was not started.
MongoDB need two element :
the "mongo" shell utility, who is used to connect to the database direcly
the "mongod" service, who is the true database programs.
to start the mongod, simply use a cmd and use the "mongod" command. this command may fail if :
the port is already used (default is 27017)
the dbpath directory was not created (default is /data/db)
Fedora repository do not install both at the same time.
the shell is in the repository under the "mongodb" name
the server is under the name "mongodb-server"
so to install both, you need to do
dnf install mongodb mongodb-server
and you can then start the mongod service with
sudo service mongod start

I am running a mean app, but when I go to run 'mongo', I get the following error:
MongoDB shell version v4.0.0
connecting to: mongodb://127.0.0.1:27017

I am sure I am missing something simple here.
mongo is the Mongo shell. It connects to the Mongo daemon, mongod, which isn't running - hence the error.
At the command-line: sudo mongod
Enter your password, and the daemon should start. Now, when you run mongo it should start up ok.
I have facing issues while running mongo commend after successful installation of mongoDB version 3.6.3.
I have run mongo commend and got the following error

Run into the same problem, my error was that I was this command:
sudo mongo service mongod start
Instead of this:
sudo service mongod start
Make sure you run the second one, hopefully that is your error source as well.
