Elasticsearch 至少需要Java 8。在撰写本文时，建议你使用Oracle JDK版本1.8.0_131。Java安装因平台而异，所以在这里不再赘述。Oracle的推荐安装文档可以在Oracle的网站上找到。在安装 Elasticsearch 之前，请先检查您的Java版本，然后再运行（如果需要，请相应地进行安装/升级）：
java -version echo $JAVA_HOME
安装了Java之后，下载并运行 Elasticsearch 。这些二进制文件可以在下载，与过去所有的所有版本一起提供。对于每个版本，您可以选择一个zip、tar、DEB或RPM包。
为了简单起见，下载Elasticsearch 5.4.1 tar，方式如下（window用户下载Elasticsearch 5.4.1 zip）
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.4.1.tar.gz
然后解压缩如下
tar -xvf elasticsearch-5.4.1.tar.gz
然后进入bin目录
cd elasticsearch-5.4.1 / bin
现在准备启动我们的节点和单个集群（Windows用户应该运行 Elasticsearch.bat文件）
./elasticsearch
如果一切顺利，您应该会看到一堆如下所示的消息：
