1.安装说明
1.1: 安装参数: ubuntu: 14.04.5; hadoop: 2.9.0; jdk: 1.8.0_121
1.2: 配置集群机器：三台主机（或虚拟机）搭建分布式集群环境(Ubuntu-14.04.5)(同一局域网)(可先准备一台):
| ip | hostname | comment |
|---|---|---|
| 192.168.1.203 | hadoop-master | Master |
| 192.168.1.204 | hadoop-slave01 | Slave 01 |
| 192.168.1.205 | hadoop-slave02 | Slave 02 |
1.3. 查看ip:
$ ifconfig注：inet addr:192.168.1.203
1.4. 配置ip:
$ vim /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.203
netmask 255.255.255.0
gateway 192.168.1.1$ vim /etc/resolvconf/resolv.conf.d/base
nameserver 192.168.1.1
nameserver 8.8.8.8/etc/init.d/networking restart1.5. 查看主机名称:
$ hostname1.6. 修改主机名称:
$ vim /etc/hostname
hadoop-master
$ reboot注：主机名称，为一个自定义字符串,此处为: hadoop-master。重启生效。
1.7. 配置ip地址和对应主机名(三台主机添加同样的配置):
$ vim /etc/hosts
127.0.0.1 localhost
192.168.1.203 hadoop-master
192.168.1.204 hadoop-slave01
192.168.1.205 hadoop-slave02温馨提示：只准备一台机器192.168.1.203（此处虚拟机），以下操作先在203上完成，最后备份主机镜像导入修改ip为集群（此处以下操作都为root用户操作，也可以其他用户hadoop）！
2:下载安装软件包
2.1: hadoop安装包下载地址
http://archive.apache.org/dist/hadoop/core/
http://archive.apache.org/dist/hadoop/core/stable2/hadoop-2.9.0.tar.gz
https://dist.apache.org/repos/dist/release/hadoop/common/
http://mirror.bit.edu.cn/apache/hadoop/common/2.2: jdk安装包下载地址
http://www.oracle.com/technetwork/java/javase/archive-139210.html2.3: Hadoop 0.18文档
http://hadoop.apache.org/docs/r1.0.4/cn/2.4: 这里准备的安装包
hadoop-2.9.0.tar.gz
jdk-8u121-linux-x64.tar.gz2.5: Ubuntu14.04.5操作系统安装，Ubuntu-14.04.5 LTS trusty
3:安装hadoop所有必需依赖软件
3.1: 安装jdk（JavaTM1.5.x+），建议选择Sun公司发行的Java版本，Jdk1.8.0_121
3.1.1: Java的jdk安装包jdk-8u121-linux-x64.tar.gz解压
$ tar zxvf jdk-8u121-linux-x64.tar.gz -C /usr/local3.1.2: Java的环境变量配置 (最后加入)
$ vim /etc/profile
#Jdk
export JAVA_HOME=/usr/local/jdk1.8.0_121
export CLASSPATH=$JAVA_HOME/lib:.
export PATH=$PATH:$JAVA_HOME/bin3.1.3: 生效环境变量，注：ubuntu系统每次登录都要生效操作
$ source /etc/profile3.1.4: Java版本检查
$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)3.2: 安装ssh、rsync、openssh-server
$ sudo apt-get install ssh
$ sudo apt-get install rsync
$ sudo apt-get install openssh-server$ dpkg -l |grep ssh
ii openssh-client 1:6.6p1-2ubuntu2.8 amd64 secure shell (SSH) client, for secure access to remote machines
ii openssh-server 1:6.6p1-2ubuntu2.8 amd64 secure shell (SSH) server, for secure access from remote machines
ii openssh-sftp-server 1:6.6p1-2ubuntu2.8 amd64 secure shell (SSH) sftp server module, for SFTP access from remote machines
ii ssh 1:6.6p1-2ubuntu2.8 all secure shell client and server (metapackage)
ii ssh-import-id 3.21-0ubuntu1 all securely retrieve an SSH public key and install it locally
$ dpkg -l |grep rsync
ii rsync 3.1.0-2ubuntu0.2 amd64 fast, versatile, remote (and local) file-copying tool注：ssh目前较可靠，专为远程登录会话和其他网络服务提供安全性的协议。必须安装并且保证sshd一直运行，以便用Hadoop脚本管理远端Hadoop守护进程。
注：rsync是类unix系统下的数据镜像备份工具。使用快速增量备份（第一次同步时rsync会复制全部内容，但在下一次只传输修改过的文件。）工具Remote Sync可以远程同步，支持本地复制，或者与其他SSH、rsync主机同步。rsync可以镜像保存整个目录树和文件系统。可以很容易做到保持原来文件的权限、时间、软硬链接等等。rsync 在传输数据的过程中可以实行压缩及解压缩操作，因此可以使用更少的带宽。可以使用scp、ssh等方式来传输文件，当然也可以通过直接的socket连接。支持匿名传输，以方便进行网站镜象。
注：openssh-server生成ssh密钥（私钥、公钥）
4. 创建目录、用户、组、密码、所属 (此处三台主机均为)：
$ mkdir -p /hadoop/bin
$ mkdir -p /hadoop/tmp
$ mkdir -p /hadoop/dfs/data
$ mkdir -p /hadoop/dfs/name
$ groupadd hadoop
$ useradd hadoop -g hadoop -d /hadoop -s /bin/bash
$ grep hadoop /etc/passwd
$ chown -R hadoop:hadoop /hadoop
$ passwd hadoop注：查看用户的根目录: $ ls ~
5: 免密码ssh设置
5.1: 生成密钥和添加免密码ssh集群用户公钥/授权，配置ssh无密码登录本机和访问集群机器(注:~ = $HOME):
$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_rsa
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys5.2: 检查：确认能否不输入口令就用ssh登录localhost:
$ ssh localhost注: 第一次”Are you sure you want to continue connecting (yes/no)? “，yes就好，进入后可用: $ exit 退出。
6: 安装hadoop
$ tar zxvf hadoop-2.9.0.tar.gz -C /hadoop/bin/6: 修改Hadoop配置文件
注：Hadoop配置文件都位于此目录下：/hadoop/bin/hadoop-2.9.0/etc/hadoop/
6.1: 修改JAVA_HOME：设置为Java安装根路径（hadoop/yarn）:
6.1.1: 修改配置文件:hadoop-env.sh
$ vim /hadoop/bin/hadoop-2.9.0/etc/hadoop/hadoop-env.sh注：hadoop-env.sh文件“# The java implementation to use.”后加入:
export JAVA_HOME=/usr/local/jdk1.8.0_1216.1.1: 修改配置文件:yarn-env.sh
$ vim /hadoop/bin/hadoop-2.9.0/etc/hadoop/yarn-env.sh注：yarn-env.sh文件“# some Java parameters.”后加入:
export JAVA_HOME=/usr/local/jdk1.8.0_1216.2: 修改slaves
注：把DataNode的主机名写入该文件，每行一个。这里让hadoop-master节点主机仅作为NameNode使用。
$ vim /hadoop/bin/hadoop-2.9.0/etc/hadoop/slaves
hadoop-slave01
hadoop-slave026.3: 修改core-site.xml
$ vim /hadoop/bin/hadoop-2.9.0/etc/hadoop/core-site.xml
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>file:/hadoop/tmp</value>

$ cp /hadoop/bin/hadoop-2.9.0/etc/hadoop/mapred-site.xml.template /hadoop/bin/hadoop-2.9.0/etc/hadoop/mapred-site.xml
$ vim /hadoop/bin/hadoop-2.9.0/etc/hadoop/mapred-site.xml
<configuration>
<property>

This command was run using /hadoop/bin/hadoop-2.9.0/share/hadoop/common/hadoop-common-2.9.0.jar温馨提示：此处192.168.1.203（此处虚拟机），配置已全部完成，现在备份主机（192.168.1.203）镜像导入204和205其他两台主机（此处虚拟机：VirtualBox-5.1.30）！
8: 主机备份的镜像导入其他两台从主机（203为主）
8.1: 修改204和205的ip和hostname：192.168.1.204 (hadoop-slave01), 192.168.1.205 (hadoop-slave02)，重启！
8.2: ping双方的ip测试网络连通性(例: 192.168.1.203 (hadoop-master)):
$ ping 192.168.1.204
$ ping 192.168.1.205
$ ping hadoop-slave01
$ ping hadoop-slave028.3: 添加免密码ssh集群用户公钥/授权:
8.3.1: 保证了三台主机电脑ssh都能连接到本地localhost，还需要让master主机免密码登录slave01和slave02主机。在master执行如下命令，将master的id_rsa.pub传送给两台slave主机。
$ scp ~/.ssh/id_rsa.pub hadoop@hadoop-slave01:/hadoop/
$ scp ~/.ssh/id_rsa.pub hadoop@hadoop-slave02:/hadoop/8.3.2:接着在hadoop-slave01、hadoop-slave02主机上将hadoop-master的公钥加入各自authorized_keys(用户公钥):
$ cat /hadoop/id_rsa.pub >> ~/.ssh/authorized_keys
$ rm /hadoop/id_rsa.pub8.3.3: 集群Master免密码ssh登录Slave测试（hadoop-master上执行）:
$ ssh hadoop-slave01
$ ssh hadoop-slave02注: 如果Master主机和Slave主机的用户名不一样，还需要在Master修改~/.ssh/config文件，如果没有此文件，自己创建文件（此处无）。
Host hadoop-master
user hadoop1
Host hadoop-slave01
user hadoop29: 格式化分布式文件系统，启动Hadoop集群 (hadoop-master上执行):、
$ /hadoop/bin/hadoop-2.9.0/bin/hdfs namenode -format
$ /hadoop/bin/hadoop-2.9.0/sbin/start-all.sh10: 关闭Hadoop集群
$ /hadoop/bin/hadoop-2.9.0/sbin/stop-all.sh11: 运行后，测试

Usage: hadoop [--config confdir] [COMMAND | CLASSNAME]
CLASSNAME run the class named CLASSNAME
or
where COMMAND is one of:
fs run a generic filesystem user client
version print the version
jar <jar> run a jar file
note: please use "yarn jar" to launch
YARN applications, not this command.
checknative [-a|-h] check native hadoop and compression libraries availability
distcp <srcurl> <desturl> copy file or directories recursively
archive -archiveName NAME -p <parent path> <src>* <dest> create a hadoop archive
classpath prints the class path needed to get the
Hadoop jar and the required libraries
credential interact with credential providers
daemonlog get/set the log level for each daemon
trace view and modify Hadoop tracing settings
Most commands print help when invoked w/o parameters.附录6：帮助文档2: $ hadoop fs –help
