Elasticsearch 安装和使用

环境

  • Windows 10
  • Java 8 +
  • Elasticsearch 5.2.2

下载安装 Elasticsearch

下载地址：https://www.elastic.co/downloads/elasticsearch 解压之后，有一个名为elasticsearch-5.2.2的文件夹，我们将其称为％ES_HOME％ 变量。 在终端窗口中，切换到％ES_HOME％目录，例如：

cd c:\elasticsearch-5.2.2

运行

命令行执行：

.\bin\elasticsearch

正常启动后，如下：

c:\elasticsearch-5.2.2>.\bin\elasticsearch

执行Ctrl-C 用来停止。

配置

默认情况下，Elasticsearch从%ES_HOME%/config/elasticsearch.ym文件加载其配置。 此配置文件的格式在配置 Elasticsearch 中进行了说明。

还可以在命令行上使用-E语法指定可以在配置文件中指定的任何设置，如下所示：

./bin/elasticsearch -Ecluster.name=my_cluster -Enode.name=node_1

注意:包含空格的值必须加上双引号， 例如-Epath.logs="C:\My Logs\logs"。

提示：通常，任何集群范围的设置（如cluster.name）都应该添加到 elasticsearch.yml 配置文件中，而任何特定于节点的设置（如node.name）都可以在命令行中指定。

确认运行情况

您可以通过向 localhost 上的端口 9200 发送 HTTP 请求来测试 Elasticsearch 节点是否正在运行：

GET /

控制台应能做出如下的响应：

{
  "name" : "OUewx-7",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "MQckjh1_To69KDvMKXbRRQ",
  "version" : {
    "number" : "5.2.2",
    "build_hash" : "f9d9b74",
    "build_date" : "2017-02-24T17:26:45.835Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}

下面是从浏览器来访问 Elasticsearch 的效果：

作为 Windows 服务

执行 bin 目录下 elasticsearch-service.bat 即可，允许用户从命令行来安装、删除、管理或配置服务，并能启动和停止服务。。

c:\elasticsearch-5.2.2\bin>elasticsearch-service

Usage: elasticsearch-service.bat install|remove|start|stop|manager [SERVICE_ID]

安装后，应能看到如下信息：

c:\elasticsearch-5.2.2\bin>elasticsearch-service install
Installing service      :  "elasticsearch-service-x64"
Using JAVA_HOME (64-bit):  "c:\jvm\jdk1.8"
The service 'elasticsearch-service-x64' has been installed.
