在 Mac OS 中安装 Elasticsearch 7.5.2

Elasticsearch 是一个基于 Lucene 构建的开源全文搜索引擎，同时也是一个分布式文档数据库。本文演示如何在 Mac OS中安装用于开发用的 Elasticsearch。

在 Mac OS 中安装 Elasticsearch 有两种方式，一种是使用 homebrew, 一种是直接下载 gz 包，手动安装，本文选择后者。

下载安装包

浏览官方网址, 选择 mac os 的版本，或是直接使用下载链接 下载 7.5.2 版。

下载文件大小为 268M

安装

将安装包解压到任意目录，在本文中我选择解压到 ~/devel 目录中。解压完成后，设置环境变量， 编辑 ~/.bash_profile 文件，加入以下内容:

ES_HOME=~/devel/elasticsearch-7.5.2
export ES_HOME

PATH=$PATH:~/devel//Users/jini/devel/elasticsearch-7.5.2/bin
export PATH

保存以后执行以下命令让修改立即生效。

source ~/.bash_profile

启动并验证

在终端执行:

elasticsearch

如果前面的步骤配置正确，则可以看到类似如下的输出:

说明 Elasticsearch 已经正常启动。

打开浏览器，浏览

http://localhost:9200/

看到如下内容，说明安装正常:
