无法从主机操作系统访问Vagrant VM中的Elasticsearch 2.0

Question

我正在努力让Elasticsearch 2.0在Vagrant虚拟机中运行。我用于1.7的方法不再有效，所以我正在尝试更新我的方法。我可以在VM中安装ES 2.0，它似乎可以在VM中正常工作，但我无法从VM外部访问它。由于某些原因，它就像VM不是端口转发端口9200，即使我告诉它。所以我想弄清楚我做错了什么。

鉴于此Vagrantfile：

Vagrant.configure(2) do |config|

  config.vm.box = "hashicorp/precise64"
  config.vm.hostname = "ES-2.0.0"
  config.vm.provision :shell, path: "bootstrap.sh"
  config.vm.network :forwarded_port, host: 9200, guest: 9200
  config.vm.synced_folder "/Users/sloan/code", "/srv/code"

  config.vm.provider "virtualbox" do |v|
    v.memory = 2048
    v.cpus = 1
    v.name = config.vm.hostname.to_s
  end

end

我的旧bootstrap.sh工作正常：

#!/usr/bin/env bash

sudo apt-get update
sudo apt-get upgrade

# install openjdk-7 
sudo apt-get purge openjdk*
sudo apt-get -y install openjdk-7-jdk

# install curl
sudo apt-get -y install curl

# install Elasticsearch 1.7.3
wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.3.tar.gz -O elasticsearch.tar.gz
tar -xf elasticsearch.tar.gz
rm elasticsearch.tar.gz
sudo mv elasticsearch-* elasticsearch
sudo mv elasticsearch /usr/local/share

# set up ES as service
curl -L http://github.com/elasticsearch/elasticsearch-servicewrapper/tarball/master | tar -xz
sudo mv *servicewrapper*/service /usr/local/share/elasticsearch/bin/
rm -Rf *servicewrapper*
sudo /usr/local/share/elasticsearch/bin/service/elasticsearch install
sudo ln -s 'readlink -f /usr/local/share/elasticsearch/bin/service/elasticsearch' /usr/local/bin/rcelasticsearch

# start ES service
sudo service elasticsearch start

# enable cors (to be able to use Sense)
sudo echo "http.cors.enabled: true" >> /usr/local/share/elasticsearch/config/elasticsearch.yml
# enable dynamic scripting
sudo echo "script.disable_dynamic: false" >> /usr/local/share/elasticsearch/config/elasticsearch.yml

sudo service elasticsearch restart

我的意思是它的工作原理是，从主机操作系统（OS X 10.9.5）我可以很好地卷曲ES：

es173 > curl localhost:9200
{
  "status" : 200,
  "name" : "Gibbon",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "1.7.3",
    "build_hash" : "05d4530971ef0ea46d0f4fa6ee64dbc8df659682",
    "build_timestamp" : "2015-10-15T09:14:17Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

但是当我使用这个新版本的bootstrap.sh时，我试图遵循Elasticsearch文档（总是一项艰巨的任务）来制作它：

#!/usr/bin/env bash

sudo apt-get update
sudo apt-get upgrade

# install curl
sudo apt-get -y install curl

# install openjdk-7 
sudo apt-get purge openjdk*
sudo apt-get -y install openjdk-7-jdk

wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
echo "deb http://packages.elastic.co/elasticsearch/2.x/debian stable main" | sudo tee -a /etc/apt/sources.list.d/elasticsearch-2.x.list
sudo apt-get update && sudo apt-get install elasticsearch

sudo update-rc.d elasticsearch defaults 95 10
sudo /etc/init.d/elasticsearch start

# enable cors (to be able to use Sense)
sudo echo "http.cors.enabled: true" >> /etc/elasticsearch/elasticsearch.yml
# enable dynamic scripting
sudo echo "script.disable_dynamic: false" >> /etc/elasticsearch/elasticsearch.yml

sudo /etc/init.d/elasticsearch restart

不起作用。从VM内部，curl localhost:9200按预期工作，但是从主机操作系统我得到：

es200 > curl localhost:9200
curl: (52) Empty reply from server

我在这里缺少什么？任何人都可以告诉我为什么不是新版本的端口转发？

Answer 1

在/etc/elasticsearch/elasticsearch.yml配置文件集network.host: 0.0.0.0中，以便elasticsearch之外可以访问localhost。记得做service elasticsearch restart。

Answer 2

在检查ES日志文件（cat /var/log/elasticsearch/elasticsearch.log）后，我发现script.disable_dynamic: false正在破坏：

我在遇到问题之后添加了该设置，但在我最初尝试评论中的建议之前，因此ES失败了。修复此设置并没有解决我原来的问题，但它掩盖了解决方案。

无论如何，这是适用于我的bootstrap.sh文件：

#!/usr/bin/env bash

sudo apt-get update
sudo apt-get upgrade

# install curl
sudo apt-get -y install curl

# install openjdk-7 
sudo apt-get purge openjdk*
sudo apt-get -y install openjdk-7-jdk

# install ES
wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
echo "deb http://packages.elastic.co/elasticsearch/2.x/debian stable main" | sudo tee -a /etc/apt/sources.list.d/elasticsearch-2.x.list
sudo apt-get update && sudo apt-get install elasticsearch
sudo update-rc.d elasticsearch defaults 95 10

# either of the next two lines is needed to be able to access "localhost:9200" from the host os
sudo echo "network.bind_host: 0" >> /etc/elasticsearch/elasticsearch.yml
sudo echo "network.host: 0.0.0.0" >> /etc/elasticsearch/elasticsearch.yml

# enable cors (to be able to use Sense)
sudo echo "http.cors.enabled: true" >> /etc/elasticsearch/elasticsearch.yml
sudo echo "http.cors.allow-origin: /https?:\/\/localhost(:[0-9]+)?/" >> /etc/elasticsearch/elasticsearch.yml

# enable dynamic scripting
sudo echo "script.inline: on" >> /etc/elasticsearch/elasticsearch.yml
sudo echo "script.indexed: on" >> /etc/elasticsearch/elasticsearch.yml

sudo /etc/init.d/elasticsearch start
