服务器信息：
192.168.91.221 （elasticsearch-node1)

192.168.91.223 （elasticsearch-node3)
1.1 安装 Java 环境（3个节点）
91221.elk.node1.com<2016-12-13 17:23:38=""> ~
root># yum install vim openssh-clients lrzsz -y
root># yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
这里 java-1.8.0-openjdk-devel 非必须安装，但以后安装插件时可能会需要 Java 的编译器（javac），因此建议提前安装好。
验证版本：
91221.elk.node1.com<2016-12-13 17:33:52=""> ~
root># java -version
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-b15)
OpenJDK 64-Bit Server VM (build 25.111-b15, mixed mode)
1.2 安装 elasticsearch 环境（3个节点）
Elasticsearch 集群：防止因Elasticsearch 服务挂掉，丢失数据
Elasticsearch 集群原理:会自动寻找同一网段cluster.name: es-cluster 名称相同的节点。

Installed head into /opt/elasticsearch-node1/plugins/head
访问
可方便查询索引数据及索引大小，如下图所示:
node2安装
91222.elk.node2.com<2016-12-13 18:15:29=""> /opt/elasticsearch-node2/bin
elasticsearch>$ /opt/elasticsearch-node2/bin/plugin install mobz/elasticsearch-head
node3安装

ES插件BigDesk安装
bigdesk支持的最新版本的ES是1.3.0 ... 1.3.x
然而想要在新版本ES上安装（2.x.x），项目中遇到过一些BUG，在ES在最新版本中有修复
1.下载bigdesk的master的zip包
2.解压到安装路径下 elasticsearch-2.4.1/plugins/目录下，会有一个bigdesk或者bigdesk-master（可以改成bigdesk）目录,然后再新建一个目录_site,压缩包里的文件放到_site目录中。
3.提示没有找到'plugin-descriptor.properties'文件，那就创建这个文件，并写入以下内容
91221.elk.node1.com<2016-12-13 20:15:42=""> /opt/elasticsearch-node1/plugins/bigdesk
elasticsearch>$ cat /opt/elasticsearch-node1/plugins/bigdesk/plugin-descriptor.properties
description=bigdesk
version=bigdesk
name=bigdesk
site=true
保存OK，大功告成。
然后在本地浏览器中输入
注：_plugin后面的bigdesk就是plugins地下目录名字，若是bigdesk-master，则需要写这个名字
本以为会正常运行，然而出现了一个js弹框，有这样的内容
**************************
Bigdesk may not work correctly!
Found ES node version:2.3.0
Require ES node version:>= 1.0.0.RC1
**************************
解决办法：
定位到plugins/bigdesk/_site/js/store目录，打开BigdeskStore.js，定位到142行
|
return (major == 1 && minor >= 0 && maintenance >= 0 && (build != 'Beta1' || build != 'Beta2'));
|
看到这么一行，把 major ==1 改成 major >=1，然后保存。
浏览器重新打开 /_plugin/bigdesk/
OK.可以看到正常运行了。
Marvel
Marvel是Elastic公司推出的商业监控方案，是用来监控Elasticsearch集群，历史状态的有力工具，便于性能优化以及故障诊断。监控主要分为六个层面，分别是集群层、节点层、索引层、分片层、事件层、Sense。
安装步骤：
1) 在Elasticsearch中安装Marvel插件。
bin/plugin install license
bin/plugin install marvel-agent
2) 在Kibana中安装Marvel插件
bin/kibana plugin --install elasticsearch/marvel/latest
3) 启动Elasticsearch和Kibana
bin/elasticsearch
bin/kibana
安装好后在浏览器中输入：即可看到界面如图9.1所示。
