mac elk5.0.1- Elasticsearch、Kibana、x-pack安装、数据库同步

ELK 包括以下几个产品 Elasticsearch  、Logstash、Kibana、三个产品组合简称,网官介绍:

https://www.elastic.co/

Elasticsearch也使用Java开发并使用Lucene作为其核心来实现所有索引和搜索的功能,但是它的目的是通过简单的RESTful API来隐藏Lucene的复杂性,从而让全文搜索变得简单。

基于restful api,其它任何语言都可以支持。这是非java开发人员最大的好处,都可以用到Lucene。

一、安装Elasticsearch

官网下载最新版本,目前是5.0.1,下载产品几个版本保持一致,要不然会启动不了。

解压包,放到/usr/local, 或者其它目录都可以。

    elasticsearch-5.0.1/bin/elasticsearch 
运行
curl -X GET http://localhost:9200/
返回类似数据就成功
{
  "name" : "qvFM1BQ",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "BWJZsv4RQtKkCTAr4tDABQ",
  "version" : {
    "number" : "5.0.1",
    "build_hash" : "080bb47",
    "build_date" : "2016-11-11T22:08:49.812Z",
    "build_snapshot" : false,
    "lucene_version" : "6.2.1"
  },
  "tagline" : "You Know, for Search"
}

二、安装Kibana可视化管理Elasticsearch,类似于phpmyadmin管理mysql

官网下载  解压到本地目录,

kibana-5.0.1/bin/kibana 

运行成功

MacBook-Pro:local lifei$ kibana-5.0.1/bin/kibana
  log   [01:43:34.722] [info][status][plugin:kibana@5.0.1] Status changed from uninitialized to green - Ready
  log   [01:43:34.781] [info][status][plugin:elasticsearch@5.0.1] Status changed from uninitialized to yellow - Waiting for Elasticsearch
  log   [01:43:34.805] [info][status][plugin:console@5.0.1] Status changed from uninitialized to green - Ready
  log   [01:43:35.140] [info][status][plugin:timelion@5.0.1] Status changed from uninitialized to green - Ready
  log   [01:43:35.147] [info][listening] Server running at http://localhost:5601
  log   [01:43:35.149] [info][status][ui settings] Status changed from uninitialized to yellow - Elasticsearch plugin is yellow
  log   [01:43:35.168] [info][status][plugin:elasticsearch@5.0.1] Status changed from yellow to green - Kibana index ready
  log   [01:43:35.169] [info][status][ui settings] Status changed from yellow to green - Ready

浏览器访问:http://localhost:5601/

 三、安装数据库同步工具:

https://github.com/siddontang/go-mysql-elasticsearch

目前除了go-mysql-elasticsearch插件,还有一个插件 https://github.com/jprante/elasticsearch-jdbc 但不支持最新5.0版本。

使用go-mysql-elasticsearch 发现效率并不高,还待再测试。


四、ik中文分词

https://github.com/medcl/elasticsearch-analysis-ik

es自带的分词对中文支持不够好。

安装ik分词需要重新编译java包,所以 mvn package, 会非常耗时。推荐加一个阿里的源。

MacBook-Pro:~ lifei$ mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/local/Cellar/maven/3.3.9/libexec
Java version: 1.8.0_111, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.11.1", arch: "x86_64", family: "mac"

 查看下maven安装位置,然后更改下maven源

vi /usr/local/Cellar/maven/3.3.9/libexec/conf/settings.xml

添加:http://maven.aliyun.com/nexus/content/groups/public/

五、安装x-pack

最好先把包下载在服务器,然后通过命令安装

bin/elasticsearch-plugin install file:///path/to/file/x-pack-5.0.1.zip

bin/kibana-plugin install file:///path/to/file/x-pack-5.0.1.zip

安装好后,通过kibana访问,默认账号/密码:elastic/changeme

x-pack提供一个月的实用期,可以去申请一个basic license,下载license,

在es服务器上面执行:

1提交license

curl -XPUT -u elastic 'http://127.0.0.1:9200/_xpack/license' -d @license.json

2、第二次同意

curl -XPUT -u elastic 'http://127.0.0.1:9200/_xpack/license?acknowledge=true' -d @license.json
