如何在Elasticsearch 2.0中启用远程访问/请求？ [英] How do I enable remote access/request in Elasticsearch 2.0?

问题描述

从v2.0开始Elasticsearch默认仅在localhost上进行监听，但是我想在localhost之外提出请求。

Starting from v2.0 Elasticsearch is listening only on localhost by default, but I'd like to make request outside localhost.

例如，像这样的请求被允许：

For example, a request like this is allowed:

http：// localhost：9200 /

但这不是：

http：// server_name：9200 / （从服务器，例如：同一台局域网中的本地计算机）。

http://server_name:9200/ (from outside of the server, eg: a local computer in the same LAN).

感谢您的帮助。

推荐答案

将elasticsearch.yml文件重命名为configuration文件夹中的elasticsearch.json，然后添加：

Rename the elasticsearch.yml file to elasticsearch.json inside config folder and add:

{
    "network" : {
        "host" : "10.0.0.4"
    }
}

另一个选项是使用ES_JAVA_OPTS或者弹性搜索命令的参数从外部提供设置，例如：

Another option is to provide the settings externally either using the ES_JAVA_OPTS or as parameters to the elasticsearch command, for example:

$ elasticsearch -Des.network.host = 10.0.0.4

另一个选项是设置es.default。前缀而不是es。前缀，这意味着默认设置将仅在配置文件中未显式设置时使用。

Another option is to set es.default. prefix instead of es. prefix, which means the default setting will be used only if not explicitly set in the configuration file.

另一个选项是使用 $ {。 ..} 配置文件中的符号将解析为环境设置，例如：

Another option is to use the ${...} notation within the configuration file which will resolve to an environment setting, for example:

{
    "network" : {
        "host" : "${ES_NET_HOST}"
    }
}

可以使用系统属性从外部设置配置文件的位置：

The location of the configuration file can be set externally using a system property:

$弹性搜索-Des.config = / path / to / config / file
