Elasticsearch7.2中文教程翻译(二):Elasticsearch安装

@高效码农  July 22, 2019

开始使用Elasticsearch

准备将Elasticsearch用于测试驱动器并亲自了解如何使用REST API来存储,搜索和分析数据?

按照此入门教程进行操作:

1.启动并运行Elasticsearch实例
2.索引一些示例文档
3.使用Elasticsearch查询语言搜索文档
4.使用存储分析和指标聚合分析结果

需要的基础知识?
查看Elasticsearch简介以学习术语并理解Elasticsearch如何工作的基础知识。如果您已经熟悉Elasticsearch并希望了解它如何与堆栈的其余部分一起工作,您可能需要跳转到 Elastic Stack Tutorial,了解如何使用Elasticsearch、Kibana、Beats和Logstash设置系统监视解决方案。

安装

Linux上的安装示例
为简单起见,我们使用tar文件。

让我们下载Elasticsearch 8.0.0 Linux tar,如下所示:

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.0.0-linux-x86_64.tar.gz

然后提取如下:

tar -xvf elasticsearch-8.0.0-linux-x86_64.tar.gz

然后它会在当前目录中创建一堆文件和文件夹。然后我们进入bin目录,如下所示:

cd elasticsearch-8.0.0 / bin

现在我们准备启动我们的节点和单个集群:

./elasticsearch

使用MSI Windows Installer 编辑的安装示例
对于Windows用户,我们建议使用MSI安装程序包。该软件包包含一个图形用户界面(GUI),可指导您完成安装过程。

首先,从https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.0.0.msi下载Elasticsearch 8.0.0 MSI 。

然后双击下载的文件以启动GUI。在第一个屏幕中,选择部署目录:

msi安装程序位置
然后选择是作为服务安装还是根据需要手动启动Elasticsearch。要与Linux示例保持一致,请选择不安装为服务:

msi安装程序没有服务
对于配置,只需保留默认值:

msi安装程序配置
再次,要与tar示例对齐,请取消选中所有插件以不安装任何插件:

msi安装程序插件
单击安装按钮后,将安装Elasticsearch:

msi安装程序成功
默认情况下,Elasticsearch将安装在%PROGRAMFILES%ElasticElasticsearch。在此处导航并进入bin目录,如下所示:

使用命令提示符:

cd %PROGRAMFILES%\ Elastic \ Elasticsearch \ bin

使用PowerShell:

cd $ env:PROGRAMFILES \ Elastic \ Elasticsearch \ bin

现在我们准备启动我们的节点和单个集群:

\ elasticsearch.exe

成功运行节点
如果一切顺利安装,你应该看到一堆如下所示的消息:

我们可以看到名为“localhost.localdomain”的节点已经启动并在单个集群中选择自己作为主节点。现在不要担心没有掌握这些输出是什么。这里最重要的是我们在一个集群中启动了一个节点。

如前所述,我们可以覆盖集群或节点名称。这可以在启动Elasticsearch时从命令行完成,如下所示:

./elasticsearch -Ecluster.name = my_cluster_name -Enode.name = my_node_name

另请注意标记为http的行,其中包含有关可从中访问节点的HTTP地址(192.168.8.112)和端口(9200)的信息。默认情况下,Elasticsearch使用port 9200来提供对其REST API的访问。如有必要,可以配置此端口。
