hadoop官网下载地址

可以利用szrz小工具，我是解压后hadoop安装目录为：

/home/tb/tbdown/hadoop-2.8.2

tar zxf  hadoop-2.8.2.tar.gz

root@ubuntu:/home/tb/tbdown# ls
dump.rdb      hadoop-2.8.2-src         hadoop-2.8.2.tar.gz  nginx-1.8.1.tar.gz
hadoop-2.8.2  hadoop-2.8.2-src.tar.gz  nginx-1.8.1          spider111

验证hadoop是否安装成功

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2# ./bin/hadoop version

修改配置

注意所有操作都在hadoop安装目录（/home/tb/tbdown/hadoop-2.8.2/）进行

如有需要改动ip配置，重启网卡 /etc/init.d/networking restart

vim /etc/hosts
添加一行
127.0.0.1 tb001

然后需要修改配置文件，在hadoop安装目录的./etc/hadoop下

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2/etc/hadoop# ls
capacity-scheduler.xml      hadoop-policy.xml        kms-log4j.properties        ssl-client.xml.example
configuration.xsl           hdfs-site.xml            kms-site.xml                ssl-server.xml.example
container-executor.cfg      httpfs-env.sh            log4j.properties            yarn-env.cmd
core-site.xml               httpfs-log4j.properties  mapred-env.cmd              yarn-env.sh
hadoop-env.cmd              httpfs-signature.secret  mapred-env.sh               yarn-site.xml
hadoop-env.sh               httpfs-site.xml          mapred-queues.xml.template
hadoop-metrics2.properties  kms-acls.xml             mapred-site.xml.template
hadoop-metrics.properties   kms-env.sh               slaves

修改配置文件前，最好先备份一下原始的配置文件

vim hadoop-env.sh

需要更改第一行的 export java home ，如果已经配置了全局java，则无需更改，否则使JAVA_HOME =/your java.jdk...*/

将simple配置文件复制一份自己定义的，yarn是用来hadoop的资源管理系统，

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2/etc/hadoop# cp mapred-site.xml.template mapred-site.xml



vim mapred-site.xml


 
  mapreduce.framework.name
  yarn
 



vim core-site.xml

如果没有设置hosts里面的对应，以下的tb001可以设置为localhost，fs.defaultFS是用来设置hadoop的文件系统，默认就是hdfs了。这样客户端可以通过8020端口来连接namenode服务，hdfs的守护进程也会通过该属性确定主机和端口


    
        fs.defaultFS
        hdfs:://tb001:8020
    


vim hdfs-site.xml

第一个参数配置为副本数，由于是单机，先为1，默认应该是3，但是我们是伪分布式，设置为3会在block做副本的时候报错，就是说无法将某块复制到3个datanode上。
另外关于副本数量，可以通过hodoop fs -ls命令看到副本的数量
第二三个参数配置为两个目录配置，配置好后启动hadoop会自动创建，默认为/tmp/,如果是虚拟机，请一定设置非/tmp路径


  dfs.replication
  1
 
 
  dfs.namenode.name.dir
  /home/tb/hadoop/dfs/name
 
 
  dfs.datanode.data.dir
  /home/tb/hadoop/dfs/data


vim yarn-site.xml
  
  yarn.nodemanager.aux-services
  mapreduce_value
 



vim slaves

如果是单机，loalhost或者修改对应hosts的值都可以
默认为localhost

启动服务

启动namenode ，启动之前先进行格式化，第一次进行时运行，如果后期再运行，将格式化所有数据

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2# ./bin/hadoop namenode -format

格式化后对应目录将会有以下变化（根据你设置的hdfs-site.xml第一个设置dfs路径的）：多了dfs目录及以下
（启动datanode会创建第二个配置文件中的目录，见下文）

root@ubuntu:/home/tb/hadoop# pwd
/home/tb/hadoop
root@ubuntu:/home/tb/hadoop# tree ./
./
└── dfs
    └── name
        └── current
            ├── fsimage_0000000000000000000
            ├── fsimage_0000000000000000000.md5
            ├── seen_txid
            └── VERSION

3 directories, 4 files

启动namenode

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2# ./sbin/hadoop-daemon.sh start namenode
starting namenode, logging to /home/tb/tbdown/hadoop-2.8.2/logs/hadoop-root-namenode-ubuntu.out
root@ubuntu:/home/tb/tbdown/hadoop-2.8.2#

如何知道namenode有没有成功呢？看下面没有对应进程，说明没有成功，下面我们调试错误

 /usr/local/java/jdk1.8.0_121/bin/jps
1533 jenkins.war
3215 Jps

调试错误

没有成功，可以查看log


root@ubuntu:/home/tb/tbdown/hadoop-2.8.2# cd logs/
root@ubuntu:/home/tb/tbdown/hadoop-2.8.2/logs# ls
hadoop-root-namenode-ubuntu.log  hadoop-root-namenode-ubuntu.out  SecurityAuth-root.audit

找到问题所在：

java.lang.IllegalArgumentException: Invalid URI for NameNode address (check fs.defaultFS): hdfs:://tb001:8020 has no authority.

看问题是没有授权，解决办法如下[可以参考文末官方文档]，ssh主要是方便主节点直接登录操作其他子节点，无需单独登录到子节点逐一管理

apt-get install ssh
sudo apt-get install pdsh
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys

再次执行启动namenode就可以了，

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2# ./sbin/hadoop-daemon.sh start namenode
starting namenode, logging to /home/tb/tbdown/hadoop-2.8.2/logs/hadoop-root-namenode-ubuntu.out

6658 NameNode
6731 Jps
1550 jenkins.war

namenode已经启动成功，继续启动其他吧

当然也可以把dfs的namenode和datanode 一起执行，执行 sbin/start-dfs.sh即可

root@ubuntu:/home/tb/tbdown/hadoop-2.8.2# sbin/start-dfs.sh
Starting namenodes on [tb001]

安装HUE

HUE GITHUB
HUE python写的，需要安装dev python包

apt-get update
apt-get install python-dev
git clone https://github.com/cloudera/hue.git
cd hue

执行 make apps

cd /home/tb/tbdown/hue/maven && mvn install
/bin/bash: mvn: command not found
Makefile:122: recipe for target 'parent-pom' failed
make: *** [parent-pom] Error 127
root@ubuntu:/home/tb/tbdown/hue#

看来是没有安装mvn

mvn -v
The program 'mvn' is currently not installed. You can install it by typing:
apt install maven
root@ubuntu:/home/tb/tbdown/hue# apt install maven

安装一下吧

apt install maven

再次 mvn -v

Apache Maven 3.3.9
Maven home: /usr/share/maven

Java home: /usr/local/java/jdk1.8.0_121/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.4.0-62-generic", arch: "amd64", family: "unix"

再次 make apps

fatal error: libxml/xmlversion.h: No such file or directory

解决办法：依次执行apt-get install libxml2-dev libxslt1-dev python-dev

然后再再次 make apps

马蛋又错了：错误部分如下：...7/src/kerberos.o sh: 1: krb5-conf..

怎么就这么难，然后又去撸了撸文档，发现人家说的清清楚楚，安装hue之前需要安装哪些东西。

You'll need these library development packages and tools installed on your system:

不好好看文档！

https://github.com/cloudera/h...

然后再再再次 make apps

10分钟后成功了

...
426 static files copied to '/home/tb/tbdown/hue/build/static', 1426 post-processed.
make[1]: Leaving directory '/home/tb/tbdown/hue/apps'
...

然后执行
build/env/bin/hue runserver
默认只能本机访问，如需外网
build/env/bin/hue runserver 0.0.0.0:8000

启动成功
