Answer 1

I just removed mongo following the instructions here: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/ And then I installed again following the instructions in the given link. Everything worked smoothly!

Answer 2

I had the same problem on my Mac, and I installed mongodb via homebrew. I solve this problem by the homebrew services command.

First start mongodb service:

$ brew services start mongodb

Start mongodb terminal

$ mongo

Stop mongodb service:

$ brew services stop mongodb

Answer 3

I faced the same problem, so please check is there mongodb folder, firstly try to remove that folder

rm -rf /var/lib/mongodb/*

Now try to start mongo and if same problem then its mongodb lock file which prevent to start mongo, so please delete the mongo lock file

rm /var/lib/mongodb/mongod.lock

For forcefully rm -rf /var/lib/mongodb/mongod.lock

service mongodb restart if already in sudo mode otherwise you need to use like sudo service mongod start

or you can start the server using fork method

mongod --fork --config /etc/mongod.conf

and for watching the same is it forked please check using the below command

ps aux | grep mongo

Answer 4

Mongo 3.*.* - OSX - 2017

From README

RUNNING

Change directory to mongodb-osx-x86_64-3.*.*/bin

To run a single server database:

$ mkdir /data/db
$ ./mongod

Go to new Terminal

$ # The mongo javascript shell connects to localhost and test database 
$ # by default -Run the following command in new terminal
$ ./mongo 
> help

Answer 5

Run the following command :

sudo rm /var/lib/mongodb/mongod.lock
sudo service mongod restart

Connection refused to MongoDB errno 111

MacOS:

rm /usr/local/var/mongodb/mongod.lock  
sudo service mongod restart

Answer 6

Make sure you have run the MongoDB's Service before you want to connect the console.

run and start the server:

$ sudo mongod

then:

$ mongo
