Getting MongoDB on Linux to listen for remote connections

Question

I have successfully installed MongoDB on Windows (on the local computer) as a service, but now I want to move MongoDb to a separate server. So I pulled tarball to a virtual server on the network (linux is running).

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 on port 28017 by default. The mongo console also works and allows me to create a new database (testdb) and add users to it.

However, I could not access the server from a remote server. When I type "testmongoserver: 28017", it does not open the HTTP console as "localhost: 28017" on my local machine. I also cannot connect using official drivers and provide a connection string.

What are the neccesarry steps for installing MongoDB on Linux so that I can access it from a remote machine using a connecting line and use its HTTP console through testmongoserver: 28017

Thank!

Answer 1

• Run netstat -a on the mongo server and check the port.
• Check your DNS settings and make sure your linux server supports external connections.
• Make sure mongodb can accept external / remote connections.

The default port for mongo is 27017. 28017 is the port for websites.

See http://www.mongodb.org/display/DOCS/Security+and+Authentication#SecurityandAuthentication-Ports

1. IP Binding Option

Bind IP is a MongoDB option that restricts connections to specific IP addresses.

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:

• Add the desired IP address by combining a comma-separated list of values ​​to bind MongoDB to multiple IP addresses.
• Delete or comment out (with #) bind_ip string. But keep in mind that an entire remote connection will be able to connect your MongoDB server!

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

Bind IP can also be specified as an argument to the command: http://docs.mongodb.org/manual/reference/program/mongod/#cmdoption--bind_ip

2. Firewall

Make sure you are not working behind a firewall

Answer 3

Make sure the following line is in the /etc/mongodb.conf file,

bind_ip = 0.0.0.0

Answer 4

Another problem may be that the mongodb port is not enabled. Check the ports included on your server from another host. To do this, you can use the command:

 sudo nmap -P0 your_server_ip 

You can get the answer as follows:

 Host is up (0.052s latency). Not shown: 997 filtered ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 443/tcp closed https 

If you are using a virtual server in the cloud like AWS, you need to add a new rule to add the mongodb port (default is 27017).

It is important . Please note: in this configuration, any user can have access to your database

Answer 5

Just this problem and it is fixed:

Change /etc/mongod.conf to sudo nano /etc/mongod.conf make sure the network section looks lower (binding to the local host does not allow remote access by default):

 # network interfaces net: port: 27017 bindIp: 0.0.0.0 

Be sure to restart mongod when you are done with the above (assuming systemd ubuntu 16.04+, etc.):

sudo service mongod restart
