I am trying to run this command from a remote ssh
mongodump --host mongodb1.example.net --port 27017 --username user --password pass --out /opt/backup/mongodump-2013-10-24
However, all I am getting is blank folders for each collections.
What am I doing wrong?
Info (if it matters):
Source Mongodb is on Windows Server
And SSH is of a remote Ubuntu Machine
Here is the terminal output:
connected to: ip.ip.ip.ip:27017
Thu Feb 18 00:46:01.757 all dbs
Thu Feb 18 00:46:01.809 DATABASE: admin to /opt/backup/mongodump-2013-10-24/admin
Thu Feb 18 00:46:01.903 DATABASE: anthony_data to /opt/backup/mongodump-2013-10-24/anthony_data
Thu Feb 18 00:46:02.004 DATABASE: temp_data to /opt/backup/mongodump-2013-10-24/temp_data
Thu Feb 18 00:46:02.104 DATABASE: zoomy to /opt/backup/mongodump-2013-10-24/zoomy
So it creates empty folder for all collections. But there is no bson in it
Check that your copy of mongodump and the database itself is the same version.
I had the exact same problem (complete with no terminal output or logs) when I tried to do a dump of a mongo 3.2.4 server with a 2.4.1 mongodump client. Removing the older client and installing the newer one resolved it immediately.
I was using the default mongodb-client deb package with Ubuntu. I removed those and installed the mongodb-org-tools package from mongodb.com https://docs.mongodb.com/master/tutorial/install-mongodb-on-ubuntu/?_ga=2.36209632.1945690590.1499275806-1594815486.1499275806
They have other install instructions for your specific OS if you are not on Ubuntu https://www.mongodb.com/download-center?jmp=nav#community
This fails:

You may want to try this command. This worked for me when shutting down normally.
sh shutdown.sh localhost 2424
To stop a running server, press Ctrl+C in the open shell that runs the server instance, or soft kill the process to be sure that the opened databases close softly. Soft killing on Windows can be done by closing the window. On Unix-like systems, a simple kill is enough (do not use kill -9 unless you want to force a hard shutdown).
Just upgraded to mongo 3.0, but mongoexport gives us a the following error: "Failed: read tcp 127.0.0.1:27020: i/o timeout" after outputting some documents (not always the same amount). mongoexport is connecting to a sharded cluster of 4 standalone mongod servers with 3 mongod config servers

This is an old question but I wanted to answer. Maybe this answer will help one of us. It might be caused by someone else trying to write to the collection you are writing. I had a smilar problem. After a long research I realised that a user with higher role was trying to write in the sametime and because his/her role is more important than mine ones request were done and mine are given IO exception.
Try closing the ports first: eg. killall -9 node
I do the following:
mongorestore -d connect connect
on my local machine and it works fine. On my development machine on amazon i get this output from the same command and the same database dump and the same version of mongodb (2.0.4):

The data imported is not complete. What do i do wrong?
The metadata.json files are only created in MongoDB 2.2 or newer, so you definitely have a newer version of mongodump on your local machine than your development machine (2.0.4).
The metadata.json file includes useful information like index definitions and capped collection properties. If you try to restore using an older version of mongorestore, it won't know how to handle those files and so your restore will not be complete. If you are relying on newer features of MongoDB such as the Aggregation Framework, these also won't be available in MongoDB 2.0.x.
You should upgrade your development machine on AWS to match the version on your local machine. If you are using a 2.2.x or 2.4.x that isn't the latest production point release in that series, you should also upgrade your local machine at the same time.
when i setup mongodb in my ubuntu , i try : ./mongo it show this error :
couldn't connect to server 127.0.0.1 shell/mongo.js
so what can i do ,
thanks
Manually remove the lockfile: sudo rm /var/lib/mongodb/mongod.lock
Run the repair script: sudo -u mongodb mongod -f /etc/mongodb.conf --repair
Please note the following:
You must run this command as the mongodb user. If you run it as root,
then root will own files in /var/lib/mongodb/ that are necessary to
run the mongodb daemon and therefore when the daemon trys to run
later as the mongodb user, it won't have permissions to start. In
that case you'll get this error: Unable to create / open lock file
for lockfilepath: /var/lib/mongodb/mongod.lock errno:13 Permission
denied, terminating.
On Ubuntu, you must specify the configuration file /etc/mongodb.conf
using the -f flag. Otherwise it will look for the data files in the
wrong place and you will see the following error: dbpath (/data/db/)
does not exist, terminating.
sudo rm /var/lib/mongodb/mongod.lock
sudo -u mongodb mongod -f /etc/mongodb.conf --repair
sudo service mongodb start
Here is all, sometimes, it takes a little while to start mongo after performing these operations.
Trying running $mongod
If you get en error such as

Then you've run into a basic startup error that is pretty common.
By default mongod will try to use /data/db for its database files, which in this case, does not exist.
You can't start
mongo
until you handle
mongod.
Try creating those directories and make sure they are writable by the same user that is running the mongod process.
**See similar question-- Getting an error, "Error: couldn't connect to server 127.0.0.1 shell/mongo.js" & when trying to run mongodb on mac osx lion
This is actually not an error... What happens here is that Mongo relies on a daemon in order to run the local database server, so in order to "fire up" the mongo server in your shell, you have to start the mongo service first.
For Fedora Linux (wich is the Distro I use) You have to run these commands:
1 sudo service mongod start
2 mongo
And there you have it! the server is going to run. Now, If you want Mongo service
to Start when the system boots then you have to run:
sudo chkconfig --levels 235 mongod on
And that's all! If you do that, now in the shell you just have to type mongo in order
to start the server but that's pretty much it, the problem is you have to start the SERVICE first and then the SERVER :)
P.S. The commands I posted might work on other linux distros as well, not just in fedora... In case not maybe you have to tweak some words depending on the distro you're using ;)
I got the same problem when I tried to install mongo. I got Error as,
Error
"Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84"
Solution:
First install mongod by using:
sudo apt-get install mongodb-server
Then type
mongod --dbpath /mongo/db
Then
sudo rm /var/lib/mongodb/mongod.lock
Then
sudo -u mongodb mongod -f /etc/mongodb.conf --repair
Thank You
You need to delete the lockfile mongod.lock or /var/lib/mongodb/mongod.lock on ubuntu, then you need to run mongod.exe or service mongodb start on ubuntu first, then run mongo.exe or mongo on ubuntu.
Either your mongod is not running (check using "ps" command) or it is listening on some outside IP address and not on localhost. So first check the process list if 'mongod' is running. If yes, check with "netstat -nap" for the related port.
Of course you can start mongod on the console manually or even look into the mongod logfile
(if there is one configured...depending on how you installed mongod).
First you have to make sure that all the files and directories in your /var/lib/mongodb/ folder (or whichever folder dbpath points to) belong to the mongodb user and mongodb group.
cd /var/lib/mongodb/
sudo chown mongodb filename.*
sudo chgrp mongodb filename.*
sudo chown -R mongodb directory
sudo chgrp -R mongodb directory
(Replace filename and directory with their respective names)
Then you can remove the lock, repair the database and restart the daemon as other people already mentioned:
sudo rm /var/lib/mongodb/mongod.lock
sudo -u mongodb mongod -f /etc/mongodb.conf --repair
sudo service mongodb start
First start your mongo server by
Users-MacBook-Pro:csv1 Admin$ mongod
all output going to: /usr/local/var/log/mongodb/mongo.log
Then open another terminal window and open shell
Users-MacBook-Pro:csv1 Admin$ mongo
Also check that your root partition has enough space to start mongod.
df -h /
You'll see smth like this on mongod launch:
Mon Aug 12 17:02:59.159 [initandlisten] recover : no journal files present, no recovery needed

On Ubuntu, try this:
sudo invoke-rc.d mongodb start
It could be combination of $PATH and Permission issue.
Try following steps given below:
Update your $PATH variable to point to your MongoDB bin file. In my case brew install MongoDB to this folder:
/usr/local/Cellar/mongodb/2.4.6/
In order to update your $PATH variable, do following:
$ sudo vi /etc/paths
Then, press ‘i’ to insert text in Vi and append the your MongoDB path to the end of the ‘paths’ file and restart the terminal.
/usr/local/Cellar/mongodb/2.4.6/bin
Use ‘Esc : w q’ to save and exit from Vi editor.
Use echo to display your path variable:
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/Cellar/mongodb/2.4.6/bin
Now try to check the Mongo version, if you get following, then you are on the right track!
$ mongo --version
MongoDB shell version: 2.4.6
Now we need to create the database directory. I used the default ‘/data/db’ location suggested in MongoDB docs. I also created a log directory to avoid any permission issues while Mongo tries to create any logs. Change ownership and that will do the job.
$ sudo mkdir /data/db
$ sudo mkdir /data/log
$ whoami
username
$ chown -R username /data
Now, we will create a default config file for MongoDB to be provided for the first time we run ‘mongod’ command. Now, I will also like to point out that ‘mongod’ will start a service, which will listen for incoming data connections. This is similar having ‘$service mysqld start’ executed.Let’s go ahead and create the config file. Please keep in mind that I have created very basic config file. However, you can add many other variables to configure MongoDB. This is the first time I am playing with MongoDB, so I just know as much as I read on MongoDB docs!I created ‘mongodb.conf’.
$ sudo vi /etc/mongodb.conf
Add following:
fork = true
port = 27017
quiet = true
dbpath = /data/db
logpath = /data/log/mongod.log
logappend = true
journal = true
Please note that the default port for MongoDB server is 27017. Use your own path for dbpath and logpath you created in Step – 5. Don’t forget to close and save the conf file.
Now we are all set to start our MongoDB service. Open two instances of Terminal.In Terminal 1, type in:
$ sudo mongod -f /etc/mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 3516
all output going to: /data/log/mongod.log
child process started successfully, parent exiting
If you get above message, then know that you have successfully started your Mongod service.
Now, to connect to it, in Terminal 2 type following:
$mongo test
MongoDB shell version: 2.4.6
connecting to: test
Server has startup warnings:
Tue Sep 3 16:55:43.527 [initandlisten]
Tue Sep 3 16:55:43.527 [initandlisten] ** WARNING: soft rlimits too low. Number of files is 256, should be at least 1000
>
Ignore the warnings, but you are successfully connected to the ‘test’ database! Cool!
That's all. I applied this solution, when I tried to install copy of MongoDB on my Mac for the first time. See if this help you too.

I solved this problem on ubuntu 12.04 by following steps:
1) sudo rm /var/log/mongodb
2) sudo rm /var/lib/mongodb
3) I removed mongo and then installed it again
4) sudo service mongodb restart
and All is Well
For Ubuntu:
Just Open the terminal and enter the below command.
You just have to restart your mongoDB.
sudo service mongodb restart
