从无业游民访问elasticsearch

Question

Hi I've been trying almost everything to access my elasticsearch database from my vagrant VM. In this forum there are plenty of threads but none of them seems to work, that's why I'm posting.

The thing is that if I type: curl -X GET http://127.0.0.1:9200 outside of vagrant I'll get the content of my elastisearch localhost.

Inside of vagrant I connect to my mongodb databases through:

mongo 10.0.2.2:27017 

Therefore, and following one of these answers:

Vagrant reverse port forwarding?

I expected that by changing this:

vagrant ssh -- -R 12345:localhost:80

into this:

vagrant ssh -- -R 12345:10.0.2.2:9200

I would be able to access my elasticsearch from vagrant if I typed:

curl -X GET http://10.0.2.2:9200

but I'm not getting anything...

This is the content of my vagrant file:

Vagrant.configure(2) do |config|
  # config.vm.box = "https://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box"
  config.vm.box = "xenial-amd64"
  config.vm.box_url = "https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-vagrant.box"
  config.vm.hostname = "proxy"


  config.vm.network "private_network", ip: "192.168.90.103"



  config.vm.provision :shell, :path => "provisions/shell/bootstrap.sh"
end

You need to make sure your vagrant-elasticsearch is listening on all network interfaces (not only localhost)

Edit the file /etc/elasticsearch/elasticsearch.yml and change a few things

network.bind_host: 0
network.host: 0.0.0.0

# I do that for cors
http.cors.enabled: true
http.cors.allow-origin: /https?:\/\/.*/

Make sure to restart elasticsearch after the changes. This will allow you to access your vagrant-elasticsearch from your host machine.

I think the easiest to work with is to set a static IP to your VM, you can edit your Vagrantfile and have (just an example of IP address)

Vagrant.configure("2") do |config|
  ...
  config.vm.network "private_network", ip: "192.168.90.103"
  ...
end

then you can easily access elasticsearch using http://192.168.90.103:9200
