ElasticSearch5.5.2：Windows下ElasticSearch安装配置
环境
1、Windows10企业版X64
2、JDK-1.8
3、ElasticSearch-5.5.2
4、elasticsearch-head插件
5、node-v6.11.2-x64.msi
1、下载软件
首先默认机器已经安装了java环境，JDK-1.8等。
1.1 、下载ElasticSearch
从官方下载中心 ElasticSearch Download 下载ElasticSearch安装包，ES的最新版本是5.5.2
开启ElasticSearch 服务
将zip文件解压到elasticsearch-5.5.2，进入 D:\work\ElasticSearch\elasticsearch-5.5.2\bin 目录，双击执行 elasticsearch.bat，该脚本文件执行 ElasticSearch 安装程序，稍等片刻，打开浏览器，输入 http://localhost:9200 ，
显式以下画面，说明ES安装成功。
1.2、下载下载elasticsearch-head
下载路径：https://github.com/mobz/elasticsearch-head
下载解压后，转到elasticsearch-head解压路径D:\work\ElasticSearch\elasticsearch-head-master，打开命令框，把把head插件的源码git clone下来：git clone git://github.com/mobz/elasticsearch-head.git
1.3、Node.js下载安装
安装后，检查是否安装成功
安装成功
2、安装grunt
grunt是一个很方便的构建工具，可以进行打包压缩、测试、执行等等的工作，5.0里的head插件就是通过grunt启动的。因此需要安装grunt：
注意：路径切到nodejs安装路径下。
打开命令框，输入：npm install -g grunt-cli
-g代表全局安装。安装路径为C:\Users\xxx\AppData\Roaming\npm，并且自动加入PATH变量。安装完成后检查一下：
3、修改head源码
目录：elasticsearch-head/Gruntfile.js：
增加hostname属性，设置为*
4、修改连接地址
目录：elasticsearch-head\_site/app.js
修改head的连接地址:
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
把localhost修改成你es的服务器地址，如：
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://10.10.10.10:9200";
5、启动elasticsearch.bat
效果图如下：
6、执行npm install 下载的包
在elasticsearch-head目录中，执行：npm install ，记住输入命令后然后回车
7、最后，在head源代码目录下启动nodejs：
grunt server
8、访问:target:9100
这个时候，访问http://localhost:9100就可以访问head插件了：
集群未连接：解决方案
修改elasticsearch.yml文件
# 增加如下字段
http.cors.enabled: true http.cors.allow-origin: "*"保存后重启启动elasticsearch.bat和head，然后访问在浏览器访问http://localhost:9100/，集群还是未连接
重新修改elasticsearch.yml文件，打开如下，里面所有配置都是注释，把必要的配置取消注释，并修改成自己实际的参数
# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please consult the documentation for further information on configuration options: # https://www.elastic.co/guide/en/elasticsearch/reference/index.html # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # #换个集群的名字，免得跟别人的集群混在一起 cluster.name: ictr_ElasticSearch # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # #换个节点名字 node.name: ictr_node1 node.master: true # # Add custom attributes to the node: # #node.attr.rack: r1 node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # #path.data: /path/to/data path.data: /data/elasticsearch # # Path to log files: # #path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # #修改一下ES的监听地址，这样别的机器也可以访问 network.host: 127.0.0.1 # # Set a custom port for HTTP: # #默认的就好 http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.zen.ping.unicast.hosts: ["127.0.0.1", "[::1]"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # #discovery.zen.minimum_master_nodes: 3 # # For more information, consult the zen discovery module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true http.cors.enabled: true http.cors.allow-origin: "*" action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history* xpack.security.enabled: false xpack.monitoring.enabled: true xpack.graph.enabled: false xpack.watcher.enabled: false xpack.ml.enabled: false #xpack.security.audit.enabled: true #http.cors.allow-headers: Authorization #action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*,.ml* #action.auto_create_index: * #vm.max_map_count=262144
保存后重启启动elasticsearch.bat和head，然后访问在浏览器访问http://localhost:9100/ 集群连接成功
* RED(红): 代表具体的分片还没有在集群中分配好；
* YELLOW(黄): 代表主分片已经分配好，但是副本尚未分配；
* GREEN(绿)：表示所有的分片都已分配好，群集正常运行； 如果在局域网中无法访问，需要修改 elasticsearch.yml配置文件，
增加“network.host: 0.0.0.0”。
9、将ElasticSearch 安装成Windows服务（Service）
转到ElasticSearch的bin目录打开命令框，输入：elasticsearch-service.bat install
打开服务界面：
启动服务，失败，查看目录下D:\work\ElasticSearch\elasticsearch-5.5.2\logs日志
错误信息如下：
[2017-09-02 13:52:13] [error] [14192] Failed creating java %JAVA_HOME%\jre\bin\server\jvm.dll
[2017-09-02 13:52:13] [error] [14192] 系统找不到指定的路径。
解决办法：
修改环境变量，把 JAVA_HOME 的环境变量由用户变量的位置移动到系统变量里面
重启elasticsearch-service服务，启动成功
