Configure remote connection to the MongoDB

Check whether you already have Mongodb process listening on the port

netstat -tulpen | grep 017

or

apt-get install procinfo

socklist - display

//Change authorization setting to disabled if you've enabled in
nano /etc/mongod.conf

sudo service mongod restart

Adding database authorisation (RoboMongo failed from Mongodb 3.0)

Creating a new user

cd /usr/bin/mongo to run mongodb shell

use admin

db.createUser( { user: "admin", pwd: "yourpassword", roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] } )

use <databasename>

db.createUser( { user: "accountUser", pwd: "password", roles: [ "readWrite", "dbAdmin" ] } ) 
db.auth("accountUser", "password")
db.getUsers()
db.dropUser(<username>)

//Now enable authorization again and restart the mongodb server

Filter IPTables to allow incoming and outgoing traffic from mongodb server

iptables -L to list the current rules
sudo iptables -L INPUT to see all the input values

iptables -A INPUT -s <ip-address> -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT 

iptables -A OUTPUT -d <ip-address> -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT

iptables-save to save the rules

then type reboot to restart your terminal and now you'll be able to acces your mongodb



The first rule allows all incoming traffic from <ip-address> on port 27017, which allows the application server to connect to the mongod instance. The second rule, allows outgoing traffic from the mongod to reach the application server.

Lastest MongoDb package on debian is bind to 127.0.0.1, this address doesn’t allow the connection by remote hosts, to change it u must set bind to 0.0.0.0 for eg

root@debian:/var/www# nano /etc/mongodb.conf


bind_ip = 0.0.0.0
port = 27017

root@debian:/var/www/lithium# /etc/init.d/mongodb restart
Done! Remember to secure the connection by password in production mode.

Binding IP
bindip=<youridaddress> and then run the following command.. make sure that /db0 folder is existed

mongod --dbpath /var/lib/mongodb/ --repairpath /var/lib/mongodb/db0

/var/log/mongodb/mongodb.log to see log file if the service can't be started

rm /var/lib/mongodb/mongod.lock to remove the lock file

mongod --repair to repair the service

sudo service mongod restart
