在windows上安装elastic search

好的，以下是在 Windows 上安装 ElasticSearch 的步骤：

1. 前置条件：

- Java 运行环境，建议安装 Java 8 或以上版本。
- 下载 ElasticSearch 安装包，建议下载最新版。

2. 安装 ElasticSearch：

- 解压下载的 ElasticSearch 压缩包。
- 修改 config 目录下的 elasticsearch.yml 文件：

- 将 cluster.name 字段设置为一个唯一的集群名称。
- 将 node.name 字段设置为一个唯一的节点名称。

- 双击 bin 目录下的 elasticsearch.bat 文件启动 ElasticSearch 服务。
- 打开浏览器访问 http://localhost:9200/，如果看到以下信息，则说明 ElasticSearch 已经成功安装：

{
  "name" : "node-1",
  "cluster_name" : "my-application",
  "cluster_uuid" : "p7X5aTzVQ7C5KJpF6XvBBg",
  "version" : {
    "number" : "7.8.1",
    "build_flavor" : "default",
    "build_type" : "zip",
    "build_hash" : "b5ca9c58fb664ca8bf9e4057fc229b3396bf3a89",
    "build_date" : "2020-07-21T16:36:48.322471Z",
    "build_snapshot" : false,
    "lucene_version" : "8.5.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

3. 配置 ElasticSearch：

- 修改 elasticsearch.yml 文件以配置 ElasticSearch。例如，将 http.port 字段设置为 9200。
- 在 config 目录下创建一个新的文件 elasticsearch.bat，内容为：

@echo off
cd /d %~dp0
bin\elasticsearch.bat

- 在 config 目录下创建一个新的文件 elasticsearch-service.bat，内容为：

@echo off
setlocal
set SERVICE_NAME=Elasticsearch
set SERVICE_DESC=Elasticsearch
set SERVICE_PATH=%~dp0
set SERVICE_START=%SERVICE_PATH%elasticsearch.bat
set SERVICE_STOP=%SERVICE_PATH%bin\elasticsearch-stop.bat
set SERVICE_WRAPPER=wrapper-windows-x86-32.exe

set SERVICE_WRAPPER_LOGLEVEL=INFO
set SERVICE_WRAPPER_PIDFILE=%SERVICE_TMP_PATH%\wrapper.pid
set SERVICE_WRAPPER_CONSOLE_LOGLEVEL=INFO
set SERVICE_WRAPPER_LOGFILE_MAXSIZE=0
set SERVICE_WRAPPER_LOGFILE_MAXFILES=0

if not exist %SERVICE_TMP_PATH% (
  mkdir %SERVICE_TMP_PATH%
)
if not exist %SERVICE_LOGS_PATH% (
  mkdir %SERVICE_LOGS_PATH%
)

if not exist "%SERVICE_PATH%\bin\%SERVICE_WRAPPER%" (
  echo "Wrapper not found at %SERVICE_PATH%\bin\%SERVICE_WRAPPER%"
  goto :eof
)

set SERVICE_WRAPPER_CMD="%SERVICE_PATH%\bin\%SERVICE_WRAPPER%" -c %SERVICE_WRAPPER_CONF%
set SERVICE_WRAPPER_CMD=%SERVICE_WRAPPER_CMD% -s %SERVICE_START%
set SERVICE_WRAPPER_CMD=%SERVICE_WRAPPER_CMD% -p %SERVICE_PID_FILE%

set SERVICE_WRAPPER_CMD=%SERVICE_WRAPPER_CMD% -Dwrapper.console.loglevel=%SERVICE_WRAPPER_CONSOLE_LOGLEVEL%
set SERVICE_WRAPPER_CMD=%SERVICE_WRAPPER_CMD% -Dwrapper.logfile.loglevel=%SERVICE_WRAPPER_LOGLEVEL%

echo Installing %SERVICE_NAME% service...
%SERVICE_WRAPPER_CMD% -i
if not errorlevel 1 (
  echo Starting %SERVICE_NAME% service...
  net start %SERVICE_NAME%
) else (
  echo Failed to install %SERVICE_NAME% service.
)

endlocal

- 运行 elasticsearch-service.bat 文件以安装 ElasticSearch 服务。

以上就是在 Windows 上安装 ElasticSearch 的步骤。
