4>.安装jdk
大家可以自行去Oracle官网下载相应的jdk，我这里给出下载地址：（推荐下载tar.gz的安装包，解压后配置环境变量即可使用）。
[root@node101.yinzhengjie.org.cn ~]# tail -3 /etc/profile#ADD JAVA_PATHJAVA_HOME=/yinzhengjie/softwares/jdkPATH=$PATH:$JAVA_HOME/bin[root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# which java/yinzhengjie/softwares/jdk/bin/java[root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# java -versionjava version "1.8.0_201"Java(TM) SE Runtime Environment (build 1.8.0_201-b09)Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)[root@node101.yinzhengjie.org.cn ~]#
5>.下载Hadoop3.1.2版本

二.安装ansible软件
1>.查看yum源，我们此处默认你的服务器是可以联网

2>. 查看当前的yum支持的ansible版本
