运行bin文件夹下的elasticsearch.bat批处理文件：

浏览器访问 localhost:9200，如下：

代码语言：javascript复制

{
  "name" : "WIN-****",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "i1HpgzPGSwe_TJlpOT3Orw",
  "version" : {
    "number" : "7.13.2",
    "build_flavor" : "default",
    "build_type" : "zip",
    "build_hash" : "4d960a0733be83dd2543ca018aa4ddc42e956800",
    "build_date" : "2021-06-10T21:01:55.251515791Z",
    "build_snapshot" : false,
    "lucene_version" : "8.8.2",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

至此，elasticsearch启动。

4.安装`elasticsearch-head`：https://github.com/mobz/elasticsearch-head

运行方法如下：

执行命令 npm run start 如下：

启动后，用ip:9200连接服务器端部署的elasticsearch，发现连接不上

查看logs/elasticsearch.log文件，如下：

代码语言：javascript复制

修改elasticsearch配置文件，如下：

代码语言：javascript复制

network.host: 192.168.*.*
discovery.seed_hosts: ["host1"]
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, X-User"

修改hosts文件，如下：

修改host文件后，再次重新启动，又出现如下情况，提示如下内容后，中止了：

代码语言：javascript复制

recoverd indices into cluster_state

但是这并不影响运行。

接下来elasticsearch-head可能还提示“集群健康值显示 未连接”，再修改elasticsearch-head中的Gruntfile.js，如下：

到这一步elasticsearch基本的步骤就算完成。
