Elasticsearch installation-plugins
Elasticsearch 扩展性非常好，有很多官方和第三方开发的插件
1. Elasticsearch-Install
Install es
download elasticsearch-1.7.5.tar.gz
cd usr/local/mySoft/deploy
tar -xvf elasticsearch-1.7.5.tar.gz
ln -s /usr/local/mySoft/deploy/elasticsearch-1.7.5/ elasticsearch
------
vim ~/.zshrc
export ES_HOME=/usr/local/xSoft/elasticsearchConfig es
$ES_HOME/config/elasticsearch.yml
cluster.name: elasticsearch_x
node.name=test-node1Startup
./bin/elasticsearch
./bin/elasticsearch -d -Xms512m -Xmx512m运行之后，会产生 data 和 logs 目录

}2. Elasticsearch-Head
ElasticSearch-Head 是一个与Elastic集群（Cluster）相交互的 Web 前台。
ES-Head的主要作用
它展现ES集群的拓扑结构，并且可以通过它来进行索引（Index）和节点（Node）级别的操作
它提供一组针对集群的查询API，并将结果以json和表格形式返回
它提供一些快捷菜单，用以展现集群的各种状态
Install-Verify
elasticsearch/bin/plugin install mobz/elasticsearch-head
open ip:9200/_plugin/head/
open ip:9200/_cluster/health?pretty3. Elasticsearch-Kopf
Kopf是一个ElasticSearch的管理工具，它也提供了对ES集群操作的API。
Install-Verify
./elasticsearch/bin/plugin install lmenezes/elasticsearch-kopf/{branch|version}
open http://localhost:9200/_plugin/kopf4. Elasticsearch-bigdesk
Bigdesk为Elastic集群提供动态的图表与统计数据。
Install-Verify
bin/plugin -install lukas-vlcek/bigdesk
删除bin/plugin --remove bigdesk
open ip:9200/_plugin/bigdesk
open ip:9200/_cluster/state?pretty5. Elasticsearch-service
elasticsearch 作为一个系统service应用 ，可以安装elasticsearch-servicewrapper插件
git clone https://github.com/elasticsearch/elasticsearch-servicewrapper
下载该插件后，解压缩。将service目录拷贝到elasticsearch安装目录的bin目录下。➜ service ll

➜ service运行这个插件的好处是：elasticsearch 需要的jvm参数和其它配置都已经配置好了，非常方便。
sh elasticsearch start;
sh elasticsearch restart;
sh elasticsearch stop;在实际生产环境中，该插件基本把参数都配置好了。我们只需要修改一下jvm分配的内存空间就好了，如 :
set.default.ES_HEAP_SIZE=16384
set.default.ES_MIN_MEM=16384
set.default.ES_MAX_MEM=19660第一次运行 elaticsearch 会产生 data-dir 与 log-dir
service log 在 logs/service.log 中。

6. Http-basic-server-plugin
不要裸奔，穿一套比基尼吧。
做一个简单的HTTP认证，elasticsearch-http-basic 提供了针对 ES HTTP 连接 的 IP白名单、密码权限 和 信任代理功能。
github :
Asquera_http_basic
Install-Verify
elasticsearch-http-basic还不支持ES标准的bin/plugin install [github-name]/[repo-name]的安装方式, 所以按照如下方式安装
mkdir -p plugins/http-basic;
mv elasticsearch-http-basic-1.5.1.jar plugins/http-basicConfig http-basic param
http.basic.enabled: true
http.basic.user: "admin"
http.basic.password: "admin"
http.basic.ipwhitelist: ["localhost", "127.0.0.1"]
http.basic.trusted_proxy_chains: []
http.basic.log: true
