### 概述 ###

ElasticSearch与JDK之间的兼容关系可以参考\[1\]

<table style="width:263px;"> 
 <tbody> 
  <tr> 
   <td style="width:140px;"><strong>&nbsp;版本</strong></td> 
   <td style="width:120px;"><strong>组件</strong></td> 
  </tr> 
  <tr> 
   <td style="width:140px;"><strong>Ubuntu</strong></td> 
   <td style="width:120px;">20.04</td> 
  </tr> 
  <tr> 
   <td style="width:140px;"><strong>ElasticSearch</strong></td> 
   <td style="width:120px;">7.10.1</td> 
  </tr> 
  <tr> 
   <td style="width:140px;"><strong>JDK</strong></td> 
   <td style="width:120px;">1.8.0_131</td> 
  </tr> 
 </tbody> 
</table>

下载地点见\[2\],用迅雷下载\[3\],否则浏览器下不动的

我下载的是elasticsearch-7.10.1-linux-x86\_64.tar.gz

**注意对于节点少的人,例如只有两台机子的,尽量下载tar.gz版本,不推荐下载deb版**

### 节点与端口设置 ###

<table style="width:199px;"> 
 <tbody> 
  <tr> 
   <td style="width:93px;"><strong>节点域名</strong></td> 
   <td style="width:103px;"><strong>http.port</strong></td> 
  </tr> 
  <tr> 
   <td style="width:93px;">Desktop</td> 
   <td style="width:103px;">9001</td> 
  </tr> 
  <tr> 
   <td style="width:93px;">Laptop</td> 
   <td style="width:103px;">9002</td> 
  </tr> 
  <tr> 
   <td style="width:93px;">Laptop</td> 
   <td style="width:103px;">9003</td> 
  </tr> 
 </tbody> 
</table>

根据\[6\]单播和多播问题,目前线上主要是单播,

那么我们线下也就单播就好了.

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

Java选项设置有三处(目前暂时不需要修改)

<table style="width:500px;"> 
 <tbody> 
  <tr> 
   <td><strong>进程</strong></td> 
   <td><strong>作用</strong></td> 
  </tr> 
  <tr> 
   <td>$ES/bin/elasticsearch</td> 
   <td>ElasticSearch的服务端</td> 
  </tr> 
  <tr> 
   <td>$ES/bin/elasticsearch-cli</td> 
   <td>ElasticSearch的客户端</td> 
  </tr> 
  <tr> 
   <td>$ES/config/jvm.options</td> 
   <td>设置堆内存[9]</td> 
  </tr> 
 </tbody> 
</table>

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#  
mkdir -p /home/appleyuchi/bigdata/elasticsearch-7.10.1-1/yml\_data  
mkdir -p /home/appleyuchi/bigdata/elasticsearch-7.10.1-1/yml\_logs

mkdir -p /home/appleyuchi/bigdata/elasticsearch-7.10.1-2/yml\_data  
mkdir -p /home/appleyuchi/bigdata/elasticsearch-7.10.1-2/yml\_logs

mkdir -p /home/appleyuchi/bigdata/elasticsearch-7.10.1-3/yml\_data  
mkdir -p /home/appleyuchi/bigdata/elasticsearch-7.10.1-3/yml\_logs

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

**安装插件:**

$ES/bin/elasticsearch-plugin install x-pack

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

\[8\]中提到以守护进程进行运行的方式

./bin/elasticsearch -d -p pid

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

目前配置参考过\[11\]

### 测试用小实验 ###

此时浏览器应该要能打开

[http://desktop:9201/][http_desktop_9201]

 <tbody> 
  <tr> 
   <td style="width:340px;"><strong>命令</strong></td> 
   <td style="width:406px;"><strong>作用</strong></td> 
  </tr> 
  <tr> 
   <td style="width:340px;">curl -XGET 'Desktop:9201'</td> 
   <td style="width:406px;">查看集群状态</td> 
  </tr> 
  <tr> 
   <td style="width:340px;"> <p>浏览器打开</p> <p><a href="http://desktop:9201/_cat/nodes?pretty" rel="nofollow">http://desktop:9201/_cat/nodes?pretty</a></p> </td>

  </tr> 
  <tr> 
   <td style="width:340px;">curl -XPUT 'Desktop:9201/blog?pretty'</td> 
   <td style="width:406px;">增加索引</td> 
  </tr> 
  <tr> 
   <td style="width:340px;">curl -XGET 'http://Desktop:9201/blog?pretty'</td> 
   <td style="width:406px;">查询索引</td> 
  </tr> 
  <tr> 
   <td style="width:340px;">curl -XDELETE 'http://Desktop:9201/blog?pretty'</td> 
   <td style="width:406px;">删除索引</td> 
  </tr> 
 </tbody> 
</table>

### **注意事项** ###

**从一个节点拷贝elasticseach 的文件夹到 其他节点时，**

**一定要把data文件夹清空。**
