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

官网 : https://www.elastic.co/

Install es

download elasticsearch-1.7.5.tar.gzcd usr/local/mySoft/deploytar -xvf elasticsearch-1.7.5.tar.gzln -s /usr/local/mySoft/deploy/elasticsearch-1.7.5/ elasticsearch------vim ~/.zshrcexport ES_HOME=/usr/local/xSoft/elasticsearch

Config es

$ES_HOME/config/elasticsearch.yml

cluster.name: elasticsearch_xnode.name=test-node1

Startup

./bin/elasticsearch./bin/elasticsearch -d -Xms512m -Xmx512m

运行之后，会产生 data 和 logs 目录

{  "status" : 200,  "name" : "node01",  "cluster_name" : "elasticsearch_x",  "version" : {    "number" : "1.7.5",    "build_hash" : "00f95f4ffca6de89d68b7ccaf80d148f1f70e4d4",    "build_timestamp" : "2016-02-02T09:55:30Z",    "build_snapshot" : false,    "lucene_version" : "4.10.4"  },  "tagline" : "You Know, for Search"}

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

1. 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

2. 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

3. 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-headopen ip:9200/_plugin/head/open ip:9200/_cluster/health?pretty

3. 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/kopf

4. 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 bigdeskopen ip:9200/_plugin/bigdeskopen ip:9200/_cluster/state?pretty

5. Elasticsearch-service

elasticsearch 作为一个系统service应用 ，可以安装elasticsearch-servicewrapper插件

github-es-service

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 lltotal 76-rwxr-xr-x  1 hp staff 55710 May 26 15:42 elasticsearch*-rw-r--r--  1 hp staff  2610 May 26 15:42 elasticsearch.bat-rw-r--r--  1 hp staff  4754 May 26 15:42 elasticsearch.conf-rwxr-xr-x  1 hp staff    64 May 26 15:42 elasticsearch32*-rwxr-xr-x  1 hp staff    64 May 26 15:42 elasticsearch64*drwxr-xr-x 16 hp staff   544 May 26 15:42 exec/drwxr-xr-x 17 hp staff   578 May 26 15:42 lib/➜  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=16384set.default.ES_MIN_MEM=16384set.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-basic

Config http-basic param

http.basic.enabled: truehttp.basic.user: "admin"http.basic.password: "admin"http.basic.ipwhitelist: ["localhost", "127.0.0.1"]http.basic.trusted_proxy_chains: []http.basic.log: true...

7. Elasticsearch-sql
