Centos6.5下ElasticSearch1.4.4的安装

1.下载ElasticSearch

官网地址 https://www.elastic.co/

2.安装elasticsearch-1.4.4.tar.gz

tar -zxvf elasticsearch-1.4.4.tar.gz

cd elasticsearch-1.4.4

3.启动

[root@jerry bin]# ./elasticsearch

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/elasticsearch/bootstrap/Elasticsearch : Unsupported major.minor version 51.0

        at java.lang.ClassLoader.loadClass(ClassLoader.java:)

Could not find the main class: org.elasticsearch.bootstrap.Elasticsearch.  Program will exit.

4.这是因为jdk的版本太低,需要至少jdk1.7(我本机的jdk是1.6的,升级到1.7)

5.安装ElasticSearch Head插件（elasticsearch-head是一个elasticsearch的集群管理工具，使用它可以在web页面查看ElasticSearch的集群数据）

[root@jerry bin]# ./plugin -install mobz/elasticsearch-head

-> Installing mobz/elasticsearch-head...

6.启动ElasticSearch

[root@jerry bin]# ./elasticsearch

7.通过web页面访问ElashticSearch集群

http://localhost:9200/_plugin/head/

8.效果图

9.安装ElasticSearch ik分词插件

1.下载ik分词器源码 https://github.com/medcl/elasticsearch-analysis-ik (右下脚Download ZIP:下载elasticsearch-analysis-ik-master.zip)

2.把elasticsearch-analysis-ik-master.zip\elasticsearch-analysis-ik-master\config\ik 文件夹拷贝到ElasticSearch/config目录下

3.修改ElasticSearch/config/elasticsearch.yml文件,在文件最下方添加

###############################################################################

index:

        analysis:

                analyzer:

                        ik:

                                alias: [ik_analyzer]

                                type: org.elasticsearch.index.analysis.IkAnalyzerProvider

                        ik_max_word:

                                type: ik

                                use_smart: false

                        ik_smart:

                                type: ik

                                use_smart: true

4.在ElasticSearch/plugins/目录下新建analysis-ik文件夹,把elasticsearch-analysis-ik-1.2.9.jar拷贝到该目录下(通过ik分词器源码生成的jar包,有人已经生成好了,可直接下载使用)

5.配置完成,重启启动ElasticSearch

6.elasticsearch-analysis-ik-1.2.9.jar下载地址
