二.安裝ansible軟件
1>.查看yum源，咱們此處默認你的服務器是能夠聯網
[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>. 查看當前的yum支持的ansible版本

[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>.你們也能夠去oracle官網下載相應的jdk1.8版本進行安裝
Oracle的jdk1.8官方下載地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html。
四.搭建HDFS徹底分佈式集羣
1>.解壓Hadoop軟件包
[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關於hdfs相關的配置文件
[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配置文件的做用： 用於定義系統級別的參數，如HDFS URL、Hadoop的臨時目錄以及用於rack-aware集羣中的配置文件的配置等，此中的參數定義會覆蓋core-default.xml文件中的默認配置。 fs.defaultFS 參數的做用： #聲明namenode的地址，至關於聲明hdfs文件系統。 hadoop.tmp.dir 參數的做用： #聲明hadoop工做目錄的地址。 --> [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 配置文件的做用： #HDFS的相關設定，如文件副本的個數、塊大小及是否使用強制權限等，此中的參數定義會覆蓋hdfs-default.xml文件中的默認配置. dfs.replication 參數的做用： #爲了數據可用性及冗餘的目的，HDFS會在多個節點上保存同一個數據塊的多個副本，其默認爲3個。而只有一個節點的僞分佈式環境中其僅用 保存一個副本便可，這能夠經過dfs.replication屬性進行定義。它是一個軟件級備份。 --> [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 配置文件的做用： #HDFS的相關設定，如reduce任務的默認個數、任務所可以使用內存的默認上下限等，此中的參數定義會覆蓋mapred-default.xml文件中的默認配置. mapreduce.framework.name 參數的做用： #指定MapReduce的計算框架，有三種可選，第一種：local(本地),第二種是classic(hadoop一代執行框架),第三種是yarn(二代執行框架)，咱們這裏配置用目前版本最新的計算框架yarn便可。 --> [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配置文件的做用： #主要用於配置調度器級別的參數. yarn.resourcemanager.hostname 參數的做用： #指定資源管理器(resourcemanager)的主機名 yarn.nodemanager.aux-services 參數的做用： #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 #該配置文件的做用：是NameNode用與記錄須要鏈接哪些DataNode服務器節點，用與啓動或中止服務時發送遠程命令指令的目標主機。 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相關的系統環境變量
[root@node101.yinzhengjie.org.cn ~]# echo ${JAVA_HOME} #咱們發現系統並無定義JAVA_HOME這個變量 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# grep JAVA_HOME /yinzhengjie/softwares/hadoop-2.9.2/etc/hadoop/hadoop-env.sh | grep -v ^# export JAVA_HOME=${JAVA_HOME} #上面咱們已經確認沒有該變量，所以咱們不該該使用默認的變量，而是指定咱們安裝JDK的路徑 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# which java #使用which命令就能夠輕鬆找到java的路徑 /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 #在這裏咱們將其更換便可,注意，雖然咱們配置的是/usr目錄，但它默認回去/usr/bin目錄下去找jdk相關命令工具，千萬別多此一舉寫成/usr/bin 喲！ [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將配置同步到其餘2個節點中（把配置文件拷貝到其餘節點的目的就是讓整個集羣共用同一套）
[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 ~]#

舒適提示，拷貝文件時咱們也可使用ansible進行拷貝，「[root@node101.yinzhengjie.org.cn ~]# ansible all -m copy -a 'src=/yinzhengjie/softwares dest=/yinzhengjie owner=root mode=0755'」，在服務器上使用該命令拷貝速度是至關可觀的，可是在虛擬機上使用這條命令，個人虛擬機居然卡頓了30分鐘尚未拷貝完成（我查看的虛擬機資源仍是充足的，配置都是4G，在虛擬機傳輸效率相比服務器上簡直相差太大！固然你能夠在電腦上使用上述命令，獲取是我Mac的問題，可是我從新安裝Mac系統發現依舊沒有出現這個問題），若是你們出現和我一眼的問題就直接使用scp進行拷貝吧，1～2分鐘就能夠拷貝完成。
5>.格式化HDFS文件系統（目的是生成初始的元數據信息，生成的信息會存放在咱們hdfs-core-site.xml配置文件中指定的工做目錄下）

NameNode啓動成功後，咱們能夠訪問到它到WebUI界面，默認的端口爲：50070
可是細心的小夥伴會發現，在NameNode的Web UI中找不到相應的DataNode節點，這是正常的，由於咱們尚未啓動DataNode呢！
啓動NameNode後，咱們會發現生成了編輯日誌，以下圖所示：
