一.下载相应的jdk和Hadoop安装包
JDK：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Hadoop：http://hadoop.apache.org/releases.html
注意，Hadoop官方虽然没有windows版本，但是可用通过“visual studio”编译工具将Linux的运行伪分布式迁移到windows中，建议安装2015版本，网上的教程有很多。遗憾的是，这个工具的使用并不是本篇博客的重点。
二.安装Java环境
1>.创建软件解压目录并授权给普通用户
[yinzhengjie@yinzhengjie ~]$ ll total 390268 -rw-rw-r--. 1 yinzhengjie yinzhengjie 214092195 Aug 26 2016 hadoop-2.7.3.tar.gz -rw-rw-r--. 1 yinzhengjie yinzhengjie 185540433 May 17 2017 jdk-8u131-linux-x64.tar.gz [yinzhengjie@yinzhengjie ~]$ sudo mkdir /soft [sudo] password for yinzhengjie: [yinzhengjie@yinzhengjie ~]$ sudo chown yinzhengjie:yinzhengjie /soft/ [yinzhengjie@yinzhengjie ~]$ ll /soft/ -d drwxr-xr-x. 2 yinzhengjie yinzhengjie 6 May 24 02:30 /soft/ [yinzhengjie@yinzhengjie ~]$
2>.解压jdk并配置软连接路径
[yinzhengjie@yinzhengjie ~]$ tar zxf jdk-8u131-linux-x64.tar.gz -C /soft/ [yinzhengjie@yinzhengjie ~]$ cd /soft/ [yinzhengjie@yinzhengjie soft]$ ll total 4 drwxr-xr-x. 8 yinzhengjie yinzhengjie 4096 Mar 15 2017 jdk1.8.0_131 [yinzhengjie@yinzhengjie soft]$ ln -s jdk1.8.0_131/ jdk [yinzhengjie@yinzhengjie soft]$ ll total 4 lrwxrwxrwx. 1 yinzhengjie yinzhengjie 13 May 24 02:33 jdk -> jdk1.8.0_131/ drwxr-xr-x. 8 yinzhengjie yinzhengjie 4096 Mar 15 2017 jdk1.8.0_131 [yinzhengjie@yinzhengjie soft]$
3>.设置Java环境变量
[yinzhengjie@yinzhengjie soft]$ sudo vi /etc/profile [yinzhengjie@yinzhengjie soft]$ tail -3 /etc/profile #Add by yinzhengjie JAVA_HOME=/soft/jdk/ PATH=$PATH:$JAVA_HOME/bin [yinzhengjie@yinzhengjie soft]$ . /etc/profile [yinzhengjie@yinzhengjie soft]$ [yinzhengjie@yinzhengjie soft]$ java -version java version "1.8.0_131" Java(TM) SE Runtime Environment (build 1.8.0_131-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode) [yinzhengjie@yinzhengjie soft]$
三.安装Hadoop
1>.解压jdk并配置软连接路径
[yinzhengjie@yinzhengjie ~]$ ll total 390268 -rw-rw-r--. 1 yinzhengjie yinzhengjie 214092195 Aug 26 2016 hadoop-2.7.3.tar.gz -rw-rw-r--. 1 yinzhengjie yinzhengjie 185540433 May 17 2017 jdk-8u131-linux-x64.tar.gz [yinzhengjie@yinzhengjie ~]$ tar zxf hadoop-2.7.3.tar.gz -C /soft/ [yinzhengjie@yinzhengjie ~]$ ln -s /soft/hadoop-2.7.3/ /soft/hadoop [yinzhengjie@yinzhengjie ~]$ ll /soft/ total 8 lrwxrwxrwx. 1 yinzhengjie yinzhengjie 19 May 24 02:40 hadoop -> /soft/hadoop-2.7.3/ drwxr-xr-x. 9 yinzhengjie yinzhengjie 4096 Aug 17 2016 hadoop-2.7.3 lrwxrwxrwx. 1 yinzhengjie yinzhengjie 13 May 24 02:33 jdk -> jdk1.8.0_131/ drwxr-xr-x. 8 yinzhengjie yinzhengjie 4096 Mar 15 2017 jdk1.8.0_131 [yinzhengjie@yinzhengjie ~]$
2>.设置Hadoop的环境变量
[yinzhengjie@yinzhengjie ~]$ sudo vi /etc/profile [sudo] password for yinzhengjie: [yinzhengjie@yinzhengjie ~]$ tail -7 /etc/profile #Add by yinzhengjie JAVA_HOME=/soft/jdk/ PATH=$PATH:$JAVA_HOME/bin #Add HADOOP_HOME HADOOP_HOME=/soft/hadoop/ PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin [yinzhengjie@yinzhengjie ~]$ [yinzhengjie@yinzhengjie ~]$ source /etc/profile [yinzhengjie@yinzhengjie ~]$ grep JAVA_HOME /soft/hadoop/etc/hadoop/hadoop-env.sh | grep -v ^# export JAVA_HOME=/soft/jdk/ [yinzhengjie@yinzhengjie ~]$
3>.验证是否安装完毕（注意，提交的目录当前用户需要有权限，因为本地部署不需要启动服务，它用的就是Linux操作系统，如果普通用户把文件直接提交到根的话肯定会报异常的哟！）
[yinzhengjie@yinzhengjie ~]$ ll total 599344 -rw-rw-r--. 1 yinzhengjie yinzhengjie 214092195 Aug 26 2016 hadoop-2.7.3.tar.gz -rw-rw-r--. 1 yinzhengjie yinzhengjie 185540433 May 17 2017 jdk-8u131-linux-x64.tar.gz -rw-r--r--. 1 yinzhengjie yinzhengjie 214092195 May 24 03:24 test [yinzhengjie@yinzhengjie ~]$ rm -rf test [yinzhengjie@yinzhengjie ~]$ [yinzhengjie@yinzhengjie ~]$ [yinzhengjie@yinzhengjie ~]$ ll total 390268 -rw-rw-r--. 1 yinzhengjie yinzhengjie 214092195 Aug 26 2016 hadoop-2.7.3.tar.gz -rw-rw-r--. 1 yinzhengjie yinzhengjie 185540433 May 17 2017 jdk-8u131-linux-x64.tar.gz [yinzhengjie@yinzhengjie ~]$ [yinzhengjie@yinzhengjie ~]$ hdfs dfs -put hadoop-2.7.3.tar.gz /home/yinzhengjie/test [yinzhengjie@yinzhengjie ~]$ tar zxf test [yinzhengjie@yinzhengjie ~]$ ll total 599348 drwxr-xr-x. 9 yinzhengjie yinzhengjie 4096 Aug 17 2016 hadoop-2.7.3 -rw-rw-r--. 1 yinzhengjie yinzhengjie 214092195 Aug 26 2016 hadoop-2.7.3.tar.gz -rw-rw-r--. 1 yinzhengjie yinzhengjie 185540433 May 17 2017 jdk-8u131-linux-x64.tar.gz -rw-r--r--. 1 yinzhengjie yinzhengjie 214092195 May 24 03:24 test [yinzhengjie@yinzhengjie ~]$
四.部署hadoop伪分布式
1>.配置三种模式并存，将源文件拷贝三份
[yinzhengjie@yinzhengjie ~]$ cd /soft/hadoop/etc/ [yinzhengjie@yinzhengjie etc]$ cp -r hadoop local [yinzhengjie@yinzhengjie etc]$ cp -r hadoop pseudo [yinzhengjie@yinzhengjie etc]$ cp -r hadoop full [yinzhengjie@yinzhengjie etc]$ ll /soft/hadoop/etc/ total 16 drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 full drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 24 02:47 hadoop drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 local drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 pseudo [yinzhengjie@yinzhengjie etc]$
2>.删除hadoop目录并创建连接文件，让其指向hadoop目录
[yinzhengjie@yinzhengjie etc]$ ll /soft/hadoop/etc/ total 16 drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 full drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 24 02:47 hadoop drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 local drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 pseudo [yinzhengjie@yinzhengjie etc]$ [yinzhengjie@yinzhengjie etc]$ [yinzhengjie@yinzhengjie etc]$ rm -rf hadoop/ [yinzhengjie@yinzhengjie etc]$ ln -s pseudo/ hadoop [yinzhengjie@yinzhengjie etc]$ ll total 12 drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 full lrwxrwxrwx. 1 yinzhengjie yinzhengjie 7 May 25 00:13 hadoop -> pseudo/ drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 local drwxr-xr-x. 2 yinzhengjie yinzhengjie 4096 May 25 00:12 pseudo [yinzhengjie@yinzhengjie etc]$
3>.修改Hadoop的配置文件
[yinzhengjie@yinzhengjie etc]$ cd /soft/hadoop/etc/hadoop/ [yinzhengjie@yinzhengjie hadoop]$ [yinzhengjie@yinzhengjie hadoop]$ more core-site.xml <?xml version="1.0"?> <configuration> <property> <name>fs.defaultFS</name> <value>hdfs://localhost/</value> </property> </configuration> <!-- core-site.xml: 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。 --> [yinzhengjie@yinzhengjie hadoop]$ more hdfs-site.xml <?xml version="1.0"?> <configuration> <property> <name>dfs.replication</name> <value>1</value> </property> </configuration> <!-- hdfs-site.xml: 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. --> [yinzhengjie@yinzhengjie hadoop]$ [yinzhengjie@yinzhengjie hadoop]$ more mapred-site.xml <?xml version="1.0"?> <configuration> <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> </configuration> <!-- mapred-site.xml： 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. --> [yinzhengjie@yinzhengjie hadoop]$ more yarn-site.xml <?xml version="1.0"?> <configuration> <property> <name>yarn.resourcemanager.hostname</name> <value>localhost</value> </property> <property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> </configuration> <!-- yarn-site.xml: 主要用于配置调度器级别的参数. --> [yinzhengjie@yinzhengjie hadoop]$
五.配置ssh免密登录
1>.在本地上生成公私秘钥对
[yinzhengjie@yinzhengjie ~]$ ssh-keygen -t rsa -P ‘’ -f ~/.ssh/id_rsa Generating public/private rsa key pair. Created directory '/home/yinzhengjie/.ssh'. Your identification has been saved in /home/yinzhengjie/.ssh/id_rsa. Your public key has been saved in /home/yinzhengjie/.ssh/id_rsa.pub. The key fingerprint is: 26:f0:d6:95:d0:67:4d:4f:9c:c2:ae:03:8b:af:cf:76 yinzhengjie@yinzhengjie The key's randomart image is: +--[ RSA 2048]----+ | .. .o..o| | ...oo.+.| | . oo. . .| | o . o . | | + S o . | | . + . o | | . . | | .o E | | .+o. | +-----------------+ [yinzhengjie@yinzhengjie ~]$
2>.使用ssh-copy-id命令分配公钥（需要输入当前用户密码）
[yinzhengjie@yinzhengjie ~]$ ssh-copy-id yinzhengjie@localhost /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys yinzhengjie@localhost's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'yinzhengjie@localhost'" and check to make sure that only the key(s) you wanted were added. [yinzhengjie@yinzhengjie ~]$
3>.测试ssh连接
[yinzhengjie@yinzhengjie ~]$ cd /soft/ [yinzhengjie@yinzhengjie soft]$ ssh yinzhengjie@localhost Last login: Fri May 25 00:50:51 2018 from localhost [yinzhengjie@yinzhengjie ~]$ who yinzhengjie pts/0 2018-05-25 00:52 (localhost) yinzhengjie pts/1 2018-05-25 00:30 (172.30.100.1) [yinzhengjie@yinzhengjie ~]$ exit logout Connection to localhost closed. [yinzhengjie@yinzhengjie soft]$ who yinzhengjie pts/1 2018-05-25 00:30 (172.30.100.1) [yinzhengjie@yinzhengjie soft]$
六.格式化hdfs文件系统
18/05/25 00:59:58 INFO namenode.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host = yinzhengjie/211.98.71.195

八.验证安装是否成功
1>.查看服务端进程是否都正常启动
[yinzhengjie@yinzhengjie ~]$ jps 10561 SecondaryNameNode 10712 ResourceManager 10377 DataNode 10811 NodeManager 10253 NameNode 11102 Jps [yinzhengjie@yinzhengjie ~]$
2>.关闭服务端防火墙
[yinzhengjie@yinzhengjie ~]$ systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2018-05-25 00:06:04 PDT; 58min ago Main PID: 761 (firewalld) CGroup: /system.slice/firewalld.service └─761 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid [yinzhengjie@yinzhengjie ~]$ systemctl stop firewalld ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units === Authentication is required to manage system services or units.
