可以从www.elastic.co下载Elasticsearch，包括以前的老版本。每个版本都支持Windows、Linux和MacOS。
Linux上安装
为了简单起见，我们使用tar包安装。
先下载Elasticsearch 7.1.0 Linux tar，如下所示:
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.0-linux-x86_64.tar.gz
然后提取:
tar -xvf elasticsearch-7.1.0-linux-x86_64.tar.gz
提取完成后，将在当前目录中生成解压后的文件夹，进入bin目录:
cd elasticsearch-7.1.0/bin
启动节点(默认集群elasticsearch):
./elasticsearch
Windows上安装
对于Windows用户，我们建议使用MSI安装程序包。该包包含一个图形用户界面(GUI)，指导您完成安装过程。
可以从https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.0.msi下载Elasticsearch 7.1.0 MSI。
双击下载的文件来完成安装。安装过程中，通常选择默认选项即可。
默认情况下，Elasticsearch将安装在%PROGRAMFILES%ElasticElasticsearch。切换到这个目录下的bin目录:
cd %PROGRAMFILES%ElasticElasticsearchin
启动节点(默认集群elasticsearch):
.elasticsearch.exe
如果一切顺利，应该会看到如下所示的消息:

可以看到名为“6-bjhwl”的节点(你的示例中名称不同)已经启动。现在还不用担心master是什么意思。这里最重要的是，我们已经在一个集群中启动了一个节点。
启动时，可以指定集群名称、节点名称：
./elasticsearch -Ecluster.name=my_cluster_name -Enode.name=my_node_name
还要注意标记为http的行，其中包含了http地址(192.168.8.112)和端口(9200)的信息。默认情况下，Elasticsearch使用端口9200提供REST API，这个端口是可配置的。
Docker 安装 (推荐学习时安装)
1. 创建Docker内部网络
创建自定义网络，同一个网络中的服务(例如Kibana)可以互相连接:
docker network create my_network
2. 下载并运行Elasticsearch
docker run -d --name elasticsearch --net my_network -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.1.0
