I've recently installed mongodb on my CentOS 6 VM running on Vagrant.
I added port forwarding to Vagrantfile to forward the mongo port
config.vm.forward_port 27017, 127017
I configured mongod to start automatically when the server starts and have confirmed that the service starts as intended.
however when i run mongo localhost:127017 from my host machine (not vagrant) i get the following error
MongoDB shell version: 1.8.2
connecting to: localhost:127017/test
Fri Jan 20 13:58:28 getaddrinfo("127.0.0.1") failed: nodename nor servname provided, or not known
Fri Jan 20 13:58:28 Error shell/mongo.js:81
exception: connect failed
any ideas?
TCP port numbers are 16-bit unsigned, which mean the max value is 65535 (2^16), and you're trying with 127017.
You will need to set the mongod bind_ip to 0.0.0.0 instead of 127.0.0.1 (which is the loopback address) so that all interfaces can access it.
Can you connect to the mongo server from vagrant ssh? If not, you might want to make sure that mongod is running.
Do you have an ip_bind set up in your mongodb.conf or mongod startup script? (If you do, you might want to unset it--not exactly sure how vagrant's port forwarding works, but this might be what's causing the problem.)
bind_ip to 0.0.0.0 does not work. Try bind_ip=127.0.0.1,10.0.0.25, that worked for me.
