【Elasticsearch】Elasticsearch 6.x 探索之路-安装_elasticsearch6.5.0 wom7 安装-优快云博客

本文详细介绍了在CentOS7环境下安装Elasticsearch的过程，包括从官网下载rpm包，使用yum命令进行安装，配置自动启动，以及通过curl命令验证安装是否成功。文章最后展示了如何确认Elasticsearch版本。

安装环境为centos7

由于rpm中默认没有Elasticsearch的源，可以从官网下载对应的rpm文件

https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html

用yum执行安装

yum install elasticsearch-6.3.0.rpm

设置Elasticsearch随系统自动启动

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

启动Elasticsearch

sudo systemctl start elasticsearch.service

等待一会后，测试连接

curl -X GET "http://localhost:9200"

如果收到以下结果，则表明安装成功，可以看见版本为6.3.0
