Getting MongoDB on Linux to listen to remote connections

Question

I've successfully installed MongoDB on Windows (on a local machine) as a service, but now I want to move MongoDb to a separate server. So I extracted the tarball to a virtual server on network (running linux).

When I connected to the server ("testmongoserver") using PuTTY from my local machine, I started the mongod server and it told me that it was listening to the default 28017 port. The mongo console is also working and allowed me to create a new database (testdb) and add users to it.

However, I could not access the server from remote. When I type testmongoserver:28017 it doesn't open the HTTP console as localhost:28017 on my local machine does. I also can't connect using official drivers and providing a connectionstring.

What are the neccesarry steps to install MongoDB on Linux, so that I could access it from a remote machine with a connectionstring and use its HTTP console via testmongoserver:28017

Thanks!

Answer 1

1. Bind IP option

Bind IP is a MongoDB option that restricts connections to specifics IPs.

Have a look at your mongod configuration file, most of the time bind_ip is set to 127.0.0.1 for obvious security reasons. You can:

1. Add your desired IP by concatenating a list of comma separated values to bind MongoDB to multiple IP addresses.
2. Remove or comment (with # character) the bind_ip line. But be aware that all remote connection will be able to connect your MongoDB server!

More about bind_ip configuration option: https://docs.mongodb.com/manual/reference/configuration-options/#net.bindIp

Bind IP can also be set as a command argument: http://docs.mongodb.org/manual/reference/program/mongod/#cmdoption--bind_ip

2. Firewall

Check that you are not running behind a firewall

Answer 2

Make sure in your /etc/mongodb.conf file you have the following line,

bind_ip = 0.0.0.0
