Cannot connect to mongodb errno:61 Connection refused

Question

I recently installed mongodb-2.6.0 with Homebrew. After successfully installed, I tried to connect using the mongo command. I am receiving the following errors

Answer 1

To solve your issue you need to follow the instructions which are then given to you by brew after you use "brew install mongodb".

To have launchd start mongodb at login:

ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

Then to load mongodb now:

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

Or, if you don't want/need launchctl, you can just run:

mongod --config /usr/local/etc/mongod.conf

You may be able to just run that last command, but it didn't work for me and I needed to run the second command. To save me in the future. I just ran the first command too. Hope that helps!

EDIT Hrishi's method of using brew services mongodb start worked good for me. I think they should include this in the mongo docs.

Answer 2

I was having the same issue when calling mongod from the command line.

I resolved this by calling instead sudo mongod.

Answer 3

In another tab, you can start the mongo shell with

mongod

Then return to the previous tab and try again. If you're having trouble setting up your mongoshell, check out this link on the mongo shell: http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes/ or this link on installing mongodb: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

Answer 4

If you have already installed MongoDB then first try to run mongod as a sudo user, I was facing the issue because of not running mongod as a superuser.

I have pasted the o/p for both the commands(mongod and sudo mongod) at very bottom, you can check that too but

First try this

sudo mongod

not this

mongod

I had installed MongoDB on my MAC OS X Sierra 10.12.6 by by running the following command in sequence.

brew update
brew install mongodb --devel
brew services start mongodb

then created a directory to which mongod process will write the data, this is optional as mongod process takes it by default, see this useful guide at https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

sudo mkdir -p /data/db

Finally started mongod process as follows

sudo mongod

Oputput of mongod (failed) and sudo mongod (succeeded) commands on my terminal.

Then I opened new terminal to start querying the MongoDB, it worked.

That's it.

Answer 5

for me on osx, I had to kill old running instance, then restarting worked.

$>ps -aef | grep mongo
502  8047     1   0 11:52AM ??         0:00.23 /usr/local/opt/mongodb/bin/mongod --config /usr/local/etc/mongod.conf 

$>sudo kill 8047

$>sudo mongod

Answer 6

My similar error is resolved by deleting "sudo rm /data/db/mongod.lock" file while trying to run mongod. Now u can run mongod and then mongo.
