> Elasticsearch5.x的安装：在ELK升级到5.0之后，有些特性发生了变化，例如全部使用JDK8，插件变化和环境校验等。

#### 一、安装Elasticsearch ####

*  在官网下载tar包，[下载地址][Link 1]
 *  下载之后解压
 *  进入bin目录下启动

> 备注：如果是root用户启动会出现异常，因为es出去安全性考虑，禁止以root用户启动，解决办法是新建一个用户，详情请看这篇博客：[CENTOS安装ElasticSearch][CENTOS_ElasticSearch]。

*  进入es的conf目录修改配置文件

cluster.name: es-cluster
    node.name: node-1
    network.host: 0.0.0.0
    http.port: 9200

*  启动ES，命令如下
    
     *  ./elasticsearch
     *  ./elasticsearch -d (这是后台启动）
 *  看到如下日志信息：

*  通过IP访问，例如我的IP是192.168.31.110，那么访问地址就是192.168.31.110:9200，可以看到如下信息

{
    name: "n1HFjO-",
    cluster_name: "elasticsearch",
    cluster_uuid: "njH6T6eMS-mDf3tloN5THg",
    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"
    }

#### 二、安装Head插件 ####

> Head插件是我们常用的插件，但是在ELK5.0以后按照之前的插件安装方式不能使用了，看了head官网之后，要单独启动一个服务才可以。

*  [Head-GitHub官网][Head-GitHub]
 *  官网简易教程

git clone git://github.com/mobz/elasticsearch-head.git
    cd elasticsearch-head
    npm install
    grunt server

**这里依赖Node环境，我们需要做一下工作：**

*  Git
 *  [Node官网][Node]

##### 1、Head插件安装 #####

*  下载并安装对应的Node安装包
 *  安装Git环境
 *  下载Head项目
 *  cd elasticsearch-head
 *  修改服务器监听地址，地址目录：head/Gruntfile.js

connect: {
        server: {
            options: {
                port: 9100,
                hostname: '*',
                base: '.',
                keepalive: true
            }
        }
    }

*  修改连接地址，目录：head/\_site/app.js

*  npm install

> 备注：如果npm源特别慢的话，可以参考这篇文档：[npm install 无响应解决方案  
> ][npm install _]

*  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。因此需要安装一下grunt：`npm install grunt-cli`
 *  grunt server：保证es服务已经启动

*  打开浏览器输入：IP:9100

*  正常的话可以看到已经连接了ES，但是ES社区中很多人反映都配置好了，但是看不到连接信息，这时候需要在在 es 的 elasticsearch.ym 里添加如下配置：

http.cors.enabled: true
    http.cors.allow-origin: "*"
