ElasticSearch 6.5.4 RPM安装

最近发布的ElasticSearch版本6.5.4基本不发布tar.gz包了(被官网隐藏了)，只发布DEB、RPM、MSI和Mac上的软件包，确实比较容易安装多了。
下载rpm包：
#wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.4.rpm

## java -version
java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)

# rpm -ivh elasticsearch-6.5.4.rpm
