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

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?

[root@node101.yinzhengjie.org.cn ~]# yum -y install java-1.8.0-openjdk-devel Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies --> Running transaction check ---> Package java-1.8.0-openjdk-devel.x86_64 1:1.8.0.201.b09-2.el7_6 will be installed --> Processing Dependency: java-1.8.0-openjdk(x86-64) = 1:1.8.0.201.b09-2.el7_6 for package: 1:java-1.8.0-openjdk-devel-1.8.0.201.b09-2.el7_6.x86_64 --> Running transaction check ---> Package java-1.8.0-openjdk.x86_64 1:1.8.0.201.b09-2.el7_6 will be installed --> Processing Dependency: java-1.8.0-openjdk-headless(x86-64) = 1:1.8.0.201.b09-2.el7_6 for package: 1:java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 --> Running transaction check ---> Package java-1.8.0-openjdk-headless.x86_64 1:1.8.0.201.b09-2.el7_6 will be installed --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================================================================================================================== Package Arch Version Repository Size ========================================================================================================================================================================================================================================== Installing: java-1.8.0-openjdk-devel x86_64 1:1.8.0.201.b09-2.el7_6 updates 9.8 M Installing for dependencies: java-1.8.0-openjdk x86_64 1:1.8.0.201.b09-2.el7_6 updates 260 k java-1.8.0-openjdk-headless x86_64 1:1.8.0.201.b09-2.el7_6 updates 32 M Transaction Summary ========================================================================================================================================================================================================================================== Install 1 Package (+2 Dependent packages) Total download size: 42 M Installed size: 144 M Downloading packages: (1/3): java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64.rpm | 260 kB 00:00:00 (2/3): java-1.8.0-openjdk-devel-1.8.0.201.b09-2.el7_6.x86_64.rpm | 9.8 MB 00:00:11 (3/3): java-1.8.0-openjdk-headless-1.8.0.201.b09-2.el7_6.x86_64.rpm | 32 MB 00:00:18 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Total 2.3 MB/s | 42 MB 00:00:18 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : 1:java-1.8.0-openjdk-headless-1.8.0.201.b09-2.el7_6.x86_64 1/3 Installing : 1:java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 2/3 Installing : 1:java-1.8.0-openjdk-devel-1.8.0.201.b09-2.el7_6.x86_64 3/3 Verifying : 1:java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 1/3 Verifying : 1:java-1.8.0-openjdk-headless-1.8.0.201.b09-2.el7_6.x86_64 2/3 Verifying : 1:java-1.8.0-openjdk-devel-1.8.0.201.b09-2.el7_6.x86_64 3/3 Installed: java-1.8.0-openjdk-devel.x86_64 1:1.8.0.201.b09-2.el7_6 Dependency Installed: java-1.8.0-openjdk.x86_64 1:1.8.0.201.b09-2.el7_6 java-1.8.0-openjdk-headless.x86_64 1:1.8.0.201.b09-2.el7_6 Complete! [root@node101.yinzhengjie.org.cn ~]#
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) OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode) [root@node101.yinzhengjie.org.cn ~]#
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’ mkdir: created directory ‘/data/hadoop/yarn’ mkdir: created directory ‘/data/hadoop/mapreduce’ [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# mkdir /yinzhengjie/{softwares,download} -pv mkdir: created directory ‘/yinzhengjie’ mkdir: created directory ‘/yinzhengjie/softwares’ mkdir: created directory ‘/yinzhengjie/download’ [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# mv ~/Downloads/hadoop-2.9.2.tar.gz /yinzhengjie/download/
[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-2.9.2/etc/hadoop/core-site.xml [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/core-site.xml <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>fs.defaultFS</name> <value>hdfs://node101.yinzhengjie.org.cn:8020</value> </property> <property> <name>hadoop.tmp.dir</name> <value>/data/hadoop/hdfs</value> </property> </configuration> <!-- core-site.xml配置文件的作用： 用于定义系统级别的参数，如HDFS URL、Hadoop的临时目录以及用于rack-aware集群中的配置文件的配置等，此中的参数定义会覆盖core-default.xml文件中的默认配置。 fs.defaultFS 参数的作用： #声明namenode的地址，相当于声明hdfs文件系统。 hadoop.tmp.dir 参数的作用： #声明hadoop工作目录的地址。 --> [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# vi /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/hdfs-site.xml [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/hdfs-site.xml <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>dfs.replication</name> <value>2</value> </property> </configuration> <!-- hdfs-site.xml 配置文件的作用： #HDFS的相关设定，如文件副本的个数、块大小及是否使用强制权限等，此中的参数定义会覆盖hdfs-default.xml文件中的默认配置. dfs.replication 参数的作用： #为了数据可用性及冗余的目的，HDFS会在多个节点上保存同一个数据块的多个副本，其默认为3个。而只有一个节点的伪分布式环境中其仅用 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 ~]#
[root@node101.yinzhengjie.org.cn ~]# vi /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/mapred-site.xml [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/mapred-site.xml <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> </configuration> <!-- mapred-site.xml 配置文件的作用： #HDFS的相关设定，如reduce任务的默认个数、任务所能够使用内存的默认上下限等，此中的参数定义会覆盖mapred-default.xml文件中的默认配置. mapreduce.framework.name 参数的作用： #指定MapReduce的计算框架，有三种可选，第一种：local(本地),第二种是classic(hadoop一代执行框架),第三种是yarn(二代执行框架)，我们这里配置用目前版本最新的计算框架yarn即可。 --> [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# vi /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/yarn-site.xml [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/yarn-site.xml <?xml version="1.0"?> <configuration> <property> <name>yarn.resourcemanager.hostname</name> <value>node101.yinzhengjie.org.cn</value> </property> <property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> </configuration> <!-- yarn-site.xml配置文件的作用： #主要用于配置调度器级别的参数. yarn.resourcemanager.hostname 参数的作用： #指定资源管理器(resourcemanager)的主机名 yarn.nodemanager.aux-services 参数的作用： #指定nodemanager使用shuffle --> [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# vi /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/slaves [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/slaves #该配置文件的作用：是NameNode用与记录需要连接哪些DataNode服务器节点，用与启动或停止服务时发送远程命令指令的目标主机。 node101.yinzhengjie.org.cn node102.yinzhengjie.org.cn node103.yinzhengjie.org.cn [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]#
3>. 添加Hadoop相关的系统环境变量
[root@node101.yinzhengjie.org.cn ~]# echo ${JAVA_HOME} #我们发现系统并没有定义JAVA_HOME这个变量 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# grep JAVA_HOME /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/hadoop-env.sh | grep -v ^# export JAVA_HOME=${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-2.9.2/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 64-Bit Server VM (build 25.201-b09, mixed mode) [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# tail -3 /etc/profile #Add HADOOP_HOME PATH HADOOP_HOME=/yinzhengjie/softwares/hadoop-2.9.2 PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin [root@node101.yinzhengjie.org.cn ~]#
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=0 >> mkdir: created directory ‘/yinzhengjie’ node103.yinzhengjie.org.cn | SUCCESS | rc=0 >> mkdir: created directory ‘/yinzhengjie’ node101.yinzhengjie.org.cn | SUCCESS | rc=0 >> [root@node101.yinzhengjie.org.cn ~]#

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）

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：
