一.主机环境准备
1>.操作系统环境

3>.配置本机的免密登录（如果不做这步的话，在启动hdfs集群时会报权限被拒绝的错误）
[root@node101.yinzhengjie.org.cn ~]# ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa Generating public/private rsa key pair. Your identification has been saved in /root/.ssh/id_rsa.

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：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html（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_PATH JAVA_HOME=/yinzhengjie/softwares/jdk PATH=$PATH:$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 -version java 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
[root@node101.yinzhengjie.org.cn ~]# wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-3.1.2/hadoop-3.1.2.tar.gz --2019-04-11 08:06:10-- http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-3.1.2/hadoop-3.1.2.tar.gz Resolving mirror.bit.edu.cn (mirror.bit.edu.cn)... 114.247.56.117, 114.247.56.117 Connecting to mirror.bit.edu.cn (mirror.bit.edu.cn)|114.247.56.117|:80... connected.

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
[root@node101.yinzhengjie.org.cn ~]# yum repolist Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com repo id repo name status base/7/x86_64 CentOS-7 - Base - mirrors.aliyun.com 10,019 extras/7/x86_64 CentOS-7 - Extras - mirrors.aliyun.com 385 updates/7/x86_64 CentOS-7 - Updates - mirrors.aliyun.com 1,511 repolist: 11,915 [root@node101.yinzhengjie.org.cn ~]#
2>. 查看当前的yum支持的ansible版本
[root@node101.yinzhengjie.org.cn ~/Downloads]# yum info ansible Loaded plugins: fastestmirror, langpacks Repodata is over 2 weeks old. Install yum-cron?

4>.编辑ansible的主机配置文件
[root@node101.yinzhengjie.org.cn ~]# tail -5 /etc/ansible/hosts [namenode] node101.yinzhengjie.org.cn [datanode] node[101:103].yinzhengjie.org.cn [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]#
5>.测试是否ansible是否可用

三.编辑hadoop 3.1.2相关配置文件
1>.解压配置文件到指定目录并配置环境变量
