一.主机环境准备
1>.操作系统环境

[root@node101.yinzhengjie.org.cn ~]#
2>.关闭防火墙
[root@node101.yinzhengjie.org.cn ~]# systemctl stop firewalld
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# systemctl stop firewalld
[root@node101.yinzhengjie.org.cn ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

Disabled
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# getenforce
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.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:zViCNdoMvFre2Sury7Sxgy1ciwZx95u0KjBlOSCA5Ek root@node101.yinzhengjie.org.cn
The key's randomart image is:
+---[RSA ]----+
|=E .. o |

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
[root@node101.yinzhengjie.org.cn ~]# ssh-copy-id root@node101.yinzhengjie.org.cn
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"

/usr/bin/ssh-copy-id: INFO: key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@node101.yinzhengjie.org.cn's password: Number of key(s) added: Now try logging into the machine, with: "ssh 'root@node101.yinzhengjie.org.cn'"
and check to make sure that only the key(s) you wanted were added. [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ssh-copy-id root@node101.yinzhengjie.org.cn
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 - /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)

[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

[root@node101.yinzhengjie.org.cn ~]# wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-3.1.2/hadoop-3.1.2.tar.gz
二.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
[root@node101.yinzhengjie.org.cn ~]# tar -zxf hadoop-3.1..tar.gz -C /yinzhengjie/softwares/
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/hadoop-3.1./

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# tail -3 /etc/profile
2>.编辑hadoop相关配置文件
[root@node101.yinzhengjie.org.cn ~]# vi /yinzhengjie/softwares/hadoop-3.1./etc/hadoop/hadoop-env.sh
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# tail - /yinzhengjie/softwares/hadoop-3.1./etc/hadoop/hadoop-env.sh
#Add Hadoop Path by yinzhengjie

3>.格式化HDFS文件系统（目的是生成初始的元数据信息，生成的信息会存放在我们hdfs-core-site.xml配置文件中指定的工作目录下！温馨提示，在搭建集群的时执行一次就ok啦！千万别每次启动就执行！）
