Chapter 1 : Lab - Configuration File : Cannot assign requested address

MongoDB University M103: Basic Cluster Administration
#1

Hey, I have created a mongodb config file named as my_mongo.conf and here are the contents :

storage:
dbPath: “/data/db”

net:
bindIp : “127.0.0.1,192.168.0.101”
port : “27000”

security:
authorization: “enabled”

However, I am trying to execute the mongod command with the config file : mongod -f my_monog.conf

I am getting the following error :

vagrant@m103:~$ mongod -f “my_mongo.conf”

I tried to change the port and ip addresses but no help.

Any suggestions?

Best,

Hey @nihal9ns

This maybe stupid question but have you tried with localhost instead of 127.0.0.1?

#3

Tried now, doesn’t help!

#4

OK what do you get from

ps -ef | grep monogd

Im wondering if you already have a mongod process running on that port, However I do remember you saying that you tried different ports.

Maybe try without the quotes around the numbers

#5

Fixed, was a problem with the port that I had entered, instead of 192.168.0.101 it should be 192.168.103.100
