Elasticsearch：Windows 7.17.7 安装

1. 下载ElasticSearch

ElasticSearch 下载地址 https://www.elastic.co/cn/downloads/past-releases#elasticsearch

根据需要，选择对应的版本下载：

2. 安装ElasticSearch

在Windows下安装需要配置与ElasticSearch的JDK，否则会出现下面的异常：

a. unable to find valid certification path to requested target
b. Future versions of Elasticsearch will require Java 11

配置环境变量ES_JAVA_HOME=%ES_HOME%\jdk，注意如果没有配置ES_HOME环境变量，那么需要指定ElasticSearch JDK的全路径。具体可以的配置信息可以在elasticsearch-env.bat中查看。

3. 启动ElasticSearch

切换到ElasticSearch目录，运行elasticsearch.bat

cd elasticsearch-7.17.7
./bin/elasticsearch.bat

启动后，可以看到终端打印使用的JDK为ElasticSearch绑定的JDK：

JVM home [F:\product\server\elasticsearch-7.17.7\jdk], using bundled JDK [true]

4. 查看ElasticSearch

启动成功后可以通过访问http://localhost:9200来查看ElasticSearch的信息：
