CentOS : How to allow incomming outside connection to specific port?

Posted on August 12, 2017

Hello, I’m newbie and I already find the solution but not any luck.

I am trying to use MongoDB on CentOS (running on port : 27017) but I try to use mongoDB’s client such as Nosqlclient,ROBO 3T and it is not connect. It is said ‘connection refuse’ so I think it is because my CentOS server is not allow incomming outside connection on port 27017.

My question is how I can allow it?

This is the result when I use : netstat -tplun

Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 11506/mongod

Thanks for advance.
