Mongodb won't start - reason: errno:111 Connection refused - node.js

Question

All of a sudden I can't get mongodb to work.
Usually I will start with
mongo
however I get this when trying to start.
MongoDB shell version: 3.0.6
connecting to: test
2016-10-11T15:36:56.462+0100 W NETWORK Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2016-10-11T15:36:56.464+0100 E QUERY Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed
at connect (src/mongo/shell/mongo.js:179:14)
at (connect):1:6 at src/mongo/shell/mongo.js:179
exception: connect failed
I haven't updated anything on the server or even logged into it until the website broke. Any ideas why this is happening? I have tried to comment out the bind_ip but I don't get why it would just stop working and failing to start.
I have also tried
sudo service mongo start
mongod start/running, process 1529
Then when I tried -
sudo service mongod status
mongod stop/waiting.
I can't start my nodejs app because it returns
/node_modules/mongoose/node_modules/mongodb/lib/server.js:22‌​8 process.nextTick(function() { throw err; }) ^ Error: connect ECONNREFUSED at exports._errnoException (util.js:746:11) at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1010:19)
I think that is because mongodb isn't starting correctly but not sure.
The error produces this

I broswed to that dir and saw this!!! Why are those files so huge?

Answer 1

It seems that your error is similar to this
Removing the /tmp/mongodb-27017.sock file should do the trick.
Also check your disk space, as it seems the process is not starting because you are missing space for the journal files (check #dave-v comment below)

Answer 2

i open file /etc/mongodb.conf and put a # in begin of line bind_ip = 127.0.0.1 (#bind_ip = 127.0.0.1) .Then restart mongodb, it's work fine again !
Warning: If you use mongodb in online server, please don't do that. Hacker can attack for this port !

Answer 3

I faced same issue , solution is here
1) Once the mongo installation done by downloading or yum install
2) Create folder db under /home/scc-dev/data/db/
3)Goto mongo folder under bin , open terminal run the below command
sudo ./mongod dbpath /home/scc-dev/data/db
4)Check few lines command running in the console
5)open new terminal under bin run the below command
sudo ./mongo
6) type command -> show dbs (it should show default dbs like local..) then it is working fine
7) if you get error like Failed to connect to 127.0.0.1:27017, reason: errno: 61 Connection refused then
8) restart the linux m/c command - > /sbin/reboot (do the steps from 3 - issue will be resolved )
To open the any ports in linux m/c
sudo iptables -I INPUT -p tcp -m tcp --dport 27017 -j ACCEPT
sudo iptables-save
