Windows下安装ElasticSearch及工具

前言
什么是ElasticSearch
官网如是介绍:Elasticsearch 是一个分布式、可扩展、实时的搜索与数据分析引擎。 它能从项目一开始就赋予你的数据以搜索、分析和探索的能力,这是通常没有预料到的。 Elasticsearch 不仅仅只是全文搜索,我们还将介绍结构化搜索、数据分析、复杂的语言处理、地理位置和对象间关联关系等。
目的
由于ElasticSearch更新的很快,所以安装它及其插件时,遇到一些坑,在国内并未找到答案,所以在此记录一下,为了以后给再遇到的这些问题的人(也包括自己)。
安装ElasticSearch
- 版本:6.4.2
- 下载地址
- 解压到本地目录
- 运行bin目录下的elasticsearch.bat文件(此文件是批处理文件,在Windows下双击也可以,但是双击之后,如果出现错误,我们是看不见的,所以此处不建议双击)
#进入cmd控制台,进入elasticsearch.bat文件所在目录,然后运行如下命令
elasticsearch.bat
- 浏览器访问http://localhost:9200/,如果出现如下则服务启动成功,否则按照错误信息,去查找
{
"name" : "node-1",
"cluster_name" : "my-application",
"cluster_uuid" : "tE18H2eXSimOzKKgAyZMtw",
"version" : {

"build_flavor" : "default",

}
安装ElasticSearch问题集锦
- 运行elasticsearch.bat 出现如下问题
此时不应有 \Java\jdk1.8.0_181\bin\java.exe" -cp "!ES_CLASSPATH!" "org.elasticsearch.tools.launchers.JvmOptionsParser" "!ES_JVM_OPTIONS!" || echo jvm_options_parser_failed"`)
解决方案:将elasticsearch.bat文件中的,解决方案来源
set "ES_JVM_OPTIONS=%ES_PATH_CONF%\jvm.options"
@setlocal
for /F "usebackq delims=" %%a in (`"%JAVA% -cp "!ES_CLASSPATH!" "org.elasticsearch.tools.launchers.JvmOptionsParser" "!ES_JVM_OPTIONS!" || echo jvm_options_parser_failed"`) do set JVM_OPTIONS=%%a
@endlocal & set "MAYBE_JVM_OPTIONS_PARSER_FAILED=%JVM_OPTIONS%" & set ES_JAVA_OPTS=%JVM_OPTIONS:${ES_TMPDIR}=!ES_TMPDIR!% %ES_JAVA_OPTS%
替换成
set ES_JVM_OPTIONS=%ES_PATH_CONF%\jvm.options
@setlocal
for /F "usebackq delims=" %%a in (`CALL %JAVA% -cp "!ES_CLASSPATH!" "org.elasticsearch.tools.launchers.JvmOptionsParser" "!ES_JVM_OPTIONS!" ^|^| echo jvm_options_parser_failed`) do set JVM_OPTIONS=%%a
@endlocal & set "MAYBE_JVM_OPTIONS_PARSER_FAILED=%JVM_OPTIONS%" & set ES_JAVA_OPTS=%JVM_OPTIONS:${ES_TMPDIR}=!ES_TMPDIR!% %ES_JAVA_OPTS%
- 出现如下错误

解决方案:将jdk与jre安装成64位,解决来源
安装Kibana
什么是Kibana
Kibana 是通向 Elastic 产品集的窗口。 它可以在 Elasticsearch 中对数据进行视觉探索和实时分析。此处简单介绍,稍后会专门写一篇博客介绍Kibana及其用法
- 版本:6.4.2
- 下载地址
- 下载下来之后,解压到相关目录下
- 打开 config/kibana.yml,并修改其中elasticsearch.url的值,此处的URL要修改成ElasticSearch启动的URL,此处是默认值,如果ElasticSearch的URL没有更改,此处也不用改。
elasticsearch.url: "http://localhost:9200"
- 使用cmd进入Kibana的bin目录,然后运行kibana.bat文件。
kibana.bat
- 打开浏览器,访问http://localhost:5601即可。如果该端口被占用了,在启动的cmd控制台有显示访问的地址,复制访问即可。
我在安装Kibana的时候没有遇到问题。
插件们
下面是ElasticSearch 5.X 版本才有的插件,6.X的这些插件都集成到Kibana与x-pack中了
X-Pack
在安装插件的时候发现,该插件已经集成到ElasticSearch中了,所以不需要单独安装。

小结
安装总结起来还是比较简单的,接下来就是开始进行搜索了。
