2>.节点角色分配
3>.登陆Apache官方网站（http://hadoop.apache.org/）
4>.选择要下载的Hadoop版本
5>.下载Hadoop软件

6>.禁用firewalld和selinux（记住，每个节点都需要操作，否则可能访问不了web UI哟！）
[root@node101.yinzhengjie.org.cn ~]# systemctl status firewalld

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

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# yum repolist
2>. 查看当前的yum支持的ansible版本
[root@node101.yinzhengjie.org.cn ~/Downloads]# yum info ansible

Description :
: Ansible is a radically simple model-driven configuration management,
: multi-node deployment, and remote task execution system. Ansible works
: over SSH and does not require any software or daemons to be installed
: on remote nodes. Extension modules can be written in any language and
: are transferred to managed machines automatically. [root@node101.yinzhengjie.org.cn ~/Downloads]#
[root@node101.yinzhengjie.org.cn ~/Downloads]# yum info ansible
3>.安装ansible

[root@node101.yinzhengjie.org.cn ~]# yum -y install java-1.8.0-openjdk-devel
2>.查看openjdk版本
[root@node101.yinzhengjie.org.cn ~]# java -version
openjdk version "1.8.0_201"
OpenJDK Runtime Environment (build 1.8.0_201-b09)

3>.大家也可以去oracle官网下载相应的jdk1.8版本进行安装
Oracle的jdk1.8官方下载地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html。
四.搭建HDFS完全分布式集群
1>.解压Hadoop软件包
[root@node101.yinzhengjie.org.cn ~]# mkdir -pv /data/hadoop/{hdfs,yarn,mapreduce}
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/hadoop’
mkdir: created directory ‘/data/hadoop/hdfs’

[root@node101.yinzhengjie.org.cn ~]# tar -zxf /yinzhengjie/download/hadoop-2.9.2.tar.gz -C /yinzhengjie/softwares/
2>.修改Hadoop关于hdfs相关的配置文件
[root@node101.yinzhengjie.org.cn ~]# vi /yinzhengjie/softwares/hadoop-2.9./etc/hadoop/core-site.xml
[root@node101.yinzhengjie.org.cn ~]#

保存一个副本即可，这可以通过dfs.replication属性进行定义。它是一个软件级备份。 --> [root@node101.yinzhengjie.org.cn ~]#

3>. 添加Hadoop相关的系统环境变量
[root@node101.yinzhengjie.org.cn ~]# echo ${JAVA_HOME} #我们发现系统并没有定义JAVA_HOME这个变量
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# grep JAVA_HOME /yinzhengjie/softwares/hadoop-2.9./etc/hadoop/hadoop-env.sh | grep -v ^#
export JAVA_HOME=${JAVA_HOME} #上面我们已经确认没有该变量，因此我们不应该使用默认的变量，而是指定我们安装JDK的路径
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# which java #使用which命令就可以轻松找到java的路径
/usr/bin/java
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# grep JAVA_HOME /yinzhengjie/softwares/hadoop-2.9./etc/hadoop/hadoop-env.sh | grep -v ^#
export JAVA_HOME=/usr #在这里我们将其更换即可,注意，虽然我们配置的是/usr目录，但它默认回去/usr/bin目录下去找jdk相关命令工具，千万别画蛇添足写成/usr/bin 哟！
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# java -version
openjdk version "1.8.0_201"
OpenJDK Runtime Environment (build 1.8.0_201-b09)
OpenJDK -Bit Server VM (build 25.201-b09, mixed mode)
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# grep JAVA_HOME /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/hadoop-env.sh | grep -v ^#
[root@node101.yinzhengjie.org.cn ~]# tail - /etc/profile
#Add HADOOP_HOME PATH
HADOOP_HOME=/yinzhengjie/softwares/hadoop-2.9.
PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# tail -3 /etc/profile
4>.使用ansible将配置同步到其他2个节点中（把配置文件拷贝到其他节点的目的就是让整个集群共用同一套）
[root@node101.yinzhengjie.org.cn ~]# ansible all -m shell -a 'mkdir -pv /yinzhengjie'
[WARNING]: Consider using file module with state=directory rather than running mkdir node102.yinzhengjie.org.cn | SUCCESS | rc= >>

温馨提示，拷贝文件时我们也可以使用ansible进行拷贝，“[root@node101.yinzhengjie.org.cn ~]# ansible all -m copy -a 'src=/yinzhengjie/softwares dest=/yinzhengjie owner=root mode=0755'”，在服务器上使用该命令拷贝速度是相当可观的，但是在虚拟机上使用这条命令，我的虚拟机竟然卡顿了30分钟还没有拷贝完成（我查看的虚拟机资源还是充足的，配置都是4G，在虚拟机传输效率相比服务器上简直相差太大！当然你可以在电脑上使用上述命令，获取是我Mac的问题，但是我重新安装Mac系统发现依旧没有出现这个问题），如果大家出现和我一眼的问题就直接使用scp进行拷贝吧，1～2分钟就可以拷贝完成。
5>.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）
[root@node101.yinzhengjie.org.cn ~]# hdfs namenode -format

[root@node101.yinzhengjie.org.cn ~]# cat /data/hadoop/hdfs/dfs/name/current/seen_txid #该文件存放的是编辑日志的编号，由于咱们是刚刚格式化hdfs文件系统，因此只有镜像文件！等启动集群并有操作写入时改值会变动！ [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ll /data/hadoop/hdfs/dfs/name/current/ #上面的格式话操作就是为了生成镜像文件！我们在数据目录可以看到，如下所示。

[root@node101.yinzhengjie.org.cn ~]# ansible all -m shell -a 'jps'
NameNode启动成功后，我们可以访问到它到WebUI界面，默认的端口为：50070
但是细心的小伙伴会发现，在NameNode的Web UI中找不到相应的DataNode节点，这是正常的，因为我们还没有启动DataNode呢！
启动NameNode后，我们会发现生成了编辑日志，如下图所示：
