Vagrant运行DSTK拒绝端口8080的连接

Question

I'm very new to the land of virtual machines and vagrant, so please forgive my general ignorance about all of this.

The other day, I downloaded DSTK vagrant box and followed the instructions on the documentation page to get it set up so I could run many, many thousands of requests through it on my local machine rather than bombarding the public server (and also, it should be faster; and also, DSTK is down at the moment so it was the only option).

After many hours of waiting for vagrant to add and init the box on my tired old hard drive, it worked! I used curl to make a few requests, got the expected responses, and patted myself on the back. I closed my terminal and put away my computer and drank beer.

... And then, the next morning, this happened:

$ curl -d "Joe Biden" "localhost:8080/text2people"
curl: (7) Failed to connect to localhost port 8080: Connection refused

I can't work out why. I tried vagrant suspend; vagrant up vagrant suspend; vagrant up . Same thing. vagrant halt; vagrant up vagrant halt; vagrant up . Same thing. When I've halted vagrant and run 'vagrant up' again, this appears in the readout, which makes me think it ought to be working.

==> default: Forwarding ports...
default: 80 => 8080 (adapter 1)
default: 22 => 2222 (adapter 1)

I can run vagrant ssh and get in, look around, and I see that all the files are in the right right place.

I suppose I could remove the box and re-add it, but it really did take hours to add and init and now I'm running up against a deadline where I need to it work, and I imagine there is a very simple thing of which I am not aware that is causing my problem. Google has thus far been unhelpful, probably because of how unfamiliar I am with vagrant, generally.

Answer 1

I have just encountered the same problem, in my case the solution was to ensure that the following line is not commented on the Vagrantfile:

config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

Answer 2

So it's not a problem with vagrant or virtualbox at all.

It turns out I just didn't stop to think about whether curl could be the culprit, and when I got around to this again, fixing it was as simple as curl "127.0.0.1:8080/..." . Apparently curl (or at least the native Mac OSX implementation) doesn't like localhost .

I did try to Google about it for a few minutes, though, and I came across my own un-answered question, which was sort of a bummer—so in case anybody else ever has this problem, here's your fix.

curl "localhost:8080/text2people" -d "Joe Biden"
curl: (7) Failed to connect to localhost port 8080: Connection refused

curl "127.0.0.1:8080/text2people" -d "Joe Biden"
