Am new to mongodb. I have installed it on my pc with wamp server and it is working fine. Now am trying to connect with EC2 remotely.
I have gone through this . But still am not getting to connect.
Here is the code

How to solve this ?
By installing all these from This was solved my problem.
The error says that the address is already in use. Are you sure it's not already running?

According to your log something is already running in mongod default port that is 27017. Just stop it and give a try.
use the following command to get the PID of the process
sudo netstat -tulnp | grep 27017
copy the PID and execute the following
sudo kill -9 <PID>
Version 2.67 of MongoDB is installed. When I run MongoD in Terminal (mac os x 10.95), here is the message I get. (BTW, I have tried Sudo)![Error][1]

If it is the first time you are running MongoDB, make sure you have you have owner permission to create mongod.lock file to create in /data/db path.
sudo chown -R `id -u` /data/db
first try:
mongo localhost
to see if there already a mongod instance running. if not, you should delete the mongod.lock
sudo rm /data/db/mongod.lock
if means you had an unclear shutdown of mongod.
Important: this assumes you don't have anything important in the DB because it seems it's running on your macbook air.
I have installed MongoDB on Mac OSX. When I do mongod it does not start any connections; instead it displays the output below. Can someone please help me to resolve this

Remove any old or corrupted .ns files in /data/db and then restart mongodb
I had this problem. I solved it by increasing the memory size for the replica using Virtual Box.
This question already has answers here:
unable to start mongodb local server

Closed 8 years ago.
I recently installed mongodb on a Centos Dedicated Server. When i try to start mongodb as a service it is give me the following error.
Starting mongod: [FAILED]
When i just execute mongod this is what i receive.

I have already tried to re-install it twice still nothing. I also have cPanel installed on this server.
Appears it is already running:
ERROR: listen(): bind() failed errno:98 Address already in use for socket: 0.0.0.0:27017

Another process is already using that port which is most likely another Mongo instance. Try running
mongo
from your command line prompt to see if you can connect using the MongoDB shell utility. Alternatively try
sudo netstat -tlnp | grep 27017
and see which process is using port 27017. On my system it's mongo:
tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 25480/mongod
Because of the size of the mongodb database I'm trying to build and because I needed a filesystem that can handle parallel writes, I moved it on a cluster that has lustreFS, which fulfills these needs.
The problem is that I can't start mongod, so I can't connect anything to the database, because mongod can't get a lock on mongod.lock. I don't have root or sudo permissions but this does not seem to be the problem here because permissions are not mentioned, as you can see:
[user#host mongo]$ ./mongod --dbpath=path-to-db

Could you please tell me if there's any way around that lock? And no, there weren't any other mongod instances running.
Solution: File locking was being disabled by cluster admins. After file locking was enabled, mongod started and accepted connections as it should.
