I'm trying to create a new collection in an already existing mongodb database on an ubuntu server. I tried running the command mongod but it says the mongod not found
Make sure your mongo server is running:
you can start using command sudo service mongod restart . Once it started just type mongo , It will take you in mongo console.
Try mongo.
mongod is the one that starts the server. mongo is the client that connects to the server.
If your environment variable is set correctly, it should work.
If it still says command not found, try /usr/bin/mongo
You can find more info here: https://docs.mongodb.com/manual/mongo/

How can I run my mongo db service on windows 10
I have downloaded mongo db. tried coping data files in required directories . Whenever I try start mongodb service from task manager->services it shows windows could not start mongo db service.
Here's the official documentation about how to install and run MonogDB in window. Link
Secondly this question is also asked before you can get help from here too.
If you already have installed MongoDB in your window OS and make sure you have set the environment variable for MongoDB.
To start MongoDB server - type 'mongod' in command prompt.
Start MongoDB server
To start client - type 'mongo' in command prompt.
Start MongoDB client
I have been trying to install MongoDB and have been following instructions on the Mongo docs, I am trying to start Mongo and I get this error
It appears as if it says that the "addr already in use"? I restarted my server and this still comes up I am unsure what to do next.
Stop the active mongod server and try it again:
sudo service mongod stop
sudo mongod
Running MongoDB Shell v-3.2.8
I've noticed that articles and tutorials always mention to run the mongod server before running the mongo shell.
However, when I skip the first step and simply type mongo into my terminal, the mongo shell works without any errors / interruptions.
MacBook:Desktop user$ mongo
MongoDB shell version: 3.2.8
connecting to: test
Why does this work? Does mongo call mongod?
The mongod is being ran as a service or daemon, which means that there is always a mongod process running listening to a port. I use ubuntu, and when I install mongodb through the package manager, it immediately starts up a mongod process and begins listening on the standard port.
Running mongo is simply a small utility that attempts to connect to the localhost at the standard ip. The data reading, writing, and querying is done by the mongod process while mongo is a small program that sends the the commands to mongod.
If mongod wasn't running, you would see an error stating "Unable to connect to mongodb server"
I noticed the same. I think mongoose is doing some smart things there, which I'm not sure how it works. But I have noticed such things before, like mongoose will automatically add an "s" to your database's name when you declare it, which is a very thoughtful act =)).
I encountered the same thing and found that in the background services if MongoDB server is running, the mongo shell will work without any error. If we stop the service, the shell will throw an error.
I'm playing with meteor, Installed it on Ubuntu 14.10 & followed the todos tutorial. The Meteor run log:
$ meteor run
[[[[[ ~/bckd/homedir/learn/meteor/mycoolapp ]]]]]
=> Started proxy.
=> Started MongoDB.
=> Started your app.
=> App running at: http://localhost:3000/
When I try to connect to mongo via another terminal, I get:
$ meteor mongo
mongo: Meteor isn't running a local MongoDB server.
This command only works while Meteor is running your application locally. Start your
application first. (This error will also occur if you asked Meteor to use a different MongoDB
server with $MONGO_URL when you ran your application.)
If you're trying to connect to the database of an app you deployed with `meteor deploy`,
specify your site's name with this command.
Trying to work around this problem I looked at the mongo command, and soon enough I figured I can connect using:
$ mongo localhost:3001
So great, that's working and it seems that I am able to use that for the time being.
But... why is the official way: meteor mongo not working in my setup, and can I do anything to fix it?
Edit 5/6/2015
After creating another account on my ubuntu, logging in and creating a new app, I run it and managed to connect to the mongo instance as intended with the meteor mongo command (without sudo). I thought it could be a result of a difference in my environment variables so I compared the two (dumping both environments with the env command. There were some extra bash variables in my primary account so one by one I've unset them until I reached two identical environments (with the exceptions of home directory values, user names, auto-generated values for gnome session tokens and such). Despite those changes, the problem consists. Another wild guess of mine was that the ~/.meteor folder has gone evil on me. So, I've removed it and reinstalled meteor. That didn't fix it either. Whatever the problem is, it's pretty stubborn.
Try:
sudo meteor mongo
it worked for me on a Vagrant box :)
You need to be the same user as the user who started Meteor.
Also you need to connect from within the application directory.
Can you connect to the database with the native MongoDB client?
Try running sudo meteor mongo - maybe the Meteor/Node process is running as root.
Looks like it's your environment variable problem.
export MONGO_URL=''
meteor mongo
Did you create the meteor app initially :
meteor create
I was having same issue on Ubuntu and found that i missed the create part as I copied the code from windows machine.
In my case(Windows 10),I had set MONGO_URL='remote url'.
In this case when you type 'meteor mongo' meteor will try to connect to the local mongodb server,but we are pointing to remote mogodb.
To point to local mongodb:
1) befor starting the app type 'set MONOGO_URL=' command in terminal.
2) now start the meteor app
3) now open a new terminal and try 'meteor mongo'
This worked for me with the same problem.
I had two terminals open: one running with meteor command, the other terminal I tried meteor mongo and received the very same message as stated in the question.
mongo: Meteor isn't running a local MongoDB server.
This command only works while Meteor is running your application locally. Start
your application first with 'meteor' and then run this command in a new
terminal. This error will also occur if you asked Meteor to use a different
MongoDB server with $MONGO_URL when you ran your application.
If you're trying to connect to the database of an app you deployed with
'meteor deploy', specify your site's name as an argument to this command.
I tried the sudo command, which did not work as well.
Here is what worked for me.
Goto running meteor server terminal and ctrl-c (shut down server).
In meteor server terminal type: meteor mongo.
Note: In my case the command worked and the terminal entered into mongo.
Type exit to exit mongo.
Type meteor to spool back up meteor server.
Goto meteor mongo terminal and type: meteor mongo.
Note: For me, Meteor was running in the other terminal and meteor mongo command did open meteor mongo for me without error.
Perhaps the something in Meteor needs to reboot which does not occur without shutting down meteor server first?
check if there is a running mongo process, and kill it manually:
ps -aux | grep mongo
sudo kill [pid]
..then restart your meteor app.
--> I think this specific situation exists only when starting meteor on a custom port (not tested, but pretty obvious)
I want to create a new database in Mongo. However, I'm having trouble connecting:
:~$ mongo
MongoDB shell version: 1.6.5
connecting to: test
Tue Dec 21 18:16:25 Error: couldn't connect to server 127.0.0.1 (anon):1154
exception: connect failed
How can I connect to mongo in order to create a new database? Alternatively, can I create a new database from the command line?
Slightly surprisingly, the Mongo docs don't seem to cover how to create a database.
Thanks.
In order to open Mongo JavaScript shell, a Listener should be initialized first.
So, first run mongod.exe before running mongo.exe. Both are in the same location(/bin).
There is no separate commands to create a db in mongodb. Just type "use dbname;" in console. Now you have created a db of the name 'dbname'. Now, if you type 'show databases' you cannot see the db name you just created. Because, mongo will not create any db, util you create collection and insert a document into that collection.
Hope this is useful to you!
cd /var/lib/mongodb/
remove mongod.lock file from this folder
sudo start mongodb (in console)
mongo (in console)
And it runs fine.
First you'll need to run mongod on one terminal. Then fire up another terminal and type mongo. This shall open the mongo shell. You also need to create /data/db/ where mongo will store your databases.
You'll need to run mongod (the daemon) before you can use mongo (the client), it's easiest to just run it in another shell; These should be in your path if mongo is installed correctly. After that the docs should get you through creating and editing dbs and collections.
Just try following commands in given order :
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --repair
sudo service mongodb start
sudo service mongodb status
