Firewalld Configuration on Centos 7.2

I have installed MongoDB on my CentOS 7.2 VPS and trying to access to the DB via Robomongo from my client. However, when I try to connect the server from the 27017 port, I get "Network is unreachable" error.

I have enabled the firewalld on the server and added an exception for 27017 port.

firewall-cmd --list-all

Result:

Result:

I got this result after I've permanently added the exception and reloaded the firewalld via --reload.

When I query the port by using:

firewall-cmd --query-port=27017/tcp

I get a "yes" from the system. However when I try to connect via Robomongo or query the port via a port checker service like http://ping.eu/port-chk/ I get a negative result.

Do you have any suggestions regarding to my case?

Thank you.

Solution

  • I was able to solve the issue with the help of the VPS support team via performing the steps below:

    Execute,

    ss -plnt

    to see the socket statistics. My output was like below:

    Socket Statistics

    As can be seen from the result mongod process is listening 27017 port only on 127.0.0.1 . In order to configure that binding edit the mongod.conf in /etc/ directory and comment out the line 

    bindIp: 127.0.0.1

    Restart the mongodb service and everything should be fine.
