Question

I\'m new in nodeJS, started learning by following a trailer on youtube, everything goes well until I added the connect function if mongodb,

mongo.connect(\"m         


        

Answer 1

If the mongoDB server is already installed and if you are unable to connect from a remote host then follow the below steps,

Login to your machine, open mongodb configuration file located at /etc/mongod.conf and change the bindIp field to specific ip / 0.0.0.0 , after that restart mongodb server.

    sudo vi /etc/mongod.conf

• The file should contain the following kind of content:

    systemLog:
        destination: file
        path: "/var/log/mongodb/mongod.log"
        logAppend: true
    storage:
        journal:
            enabled: true
    processManagement:
        fork: true
    net:
        bindIp: 127.0.0.1  // change here to 0.0.0.0
        port: 27017
    setParameter:
        enableLocalhostAuthBypass: false
  

• Once you change the bindIp, then you have to restart the mongodb, using the following command

    sudo service mongod restart
  

• Now you'll be able to connect to the mongodb server, from remote server.
