hadoop安装包：hadoop-2.2.0.tar.gz
操作系统： CentOS6.4
jdk版本： jdk1.7.0_21
（修改主机名的命令为：hostname新名称）
1.1 master主机名称修改
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master
1.2 slaver01主机名称修改
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=slaver01
1.3 slaver02主机名称修改
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=slaver02
将上面两个文件修改完后，并不能立刻生效。如果要立刻生效的话，可以用 hostname your-hostname 作临时修改，它只是临时地修改主机名，系统重启后会恢复原样的。但修改上面两个文件是永久的，重启系统会得到新的主机名。
重启后查看主机名 uname
-n
1.4 修改hosts文件
假设有三台机器，主机名分别为master,slaver01,slaver02,IP地址为192.168.142.129,192.168.142.130,192.168.142.131，
master作为namenode，
slaver01,slaver02作为datanode，刚两者的hosts文件配置是一样的，如下：
[root@slaver02~]# cat /etc/hosts
192.168.159.129 master
192.168.159.130 slaver01
192.168.159.131 slaver02
$cd ~/.ssh
$ssh-keygen -t rsa
--------------------然后一直按回车键，就会按照默认的选项将生成的密钥保存在.ssh/id_rsa文件中。
catid_rsa.pub > authorized_keys
在各个节点的authorized_keys生成
然后合并各个节点生成的密钥
cd.ssh
scproot@slaver01:/root/.ssh/authorized_keys authorized_keys_from_slaver01
scproot@slaver02:/root/.ssh/authorized_keys authorized_keys_from_slaver02
catauthorized_keys_from_slaver01 authorized_keys_from_slaver02>>authorized_keys
这个就是合并后的authorized_keys文件。
把刚刚产生的authorized_keys文件拷一份到datanode上.
scpauthorized_keys root@slaver01:/root/.ssh/
scpauthorized_keysroot@slaver02:/root/.ssh/
------
最后进入所有机器的.ssh目录，改变authorized_keys文件的许可权限。
$chmod 644 authorized_keys
这时从namenode所在机器向其他datanode所在机器发起ssh连接，只有在第一次登录时需要输入密码，以后则不需要。
$ tar–xzvfhadoop-2.2.0.tar.gz--------------解压
解压完成后，编辑配置文件，这里要涉及到的配置文件有7个：
~/hadoop-2.2.0/etc/hadoop/hadoop-env.sh
exportJAVA_HOME=/usr/java/jdk1.7.0_21
~/hadoop-2.2.0/etc/hadoop/yarn-env.sh
exportJAVA_HOME=/usr/java/jdk1.7.0_21
~/hadoop-2.2.0/etc/hadoop/slaves
[root@masterhadoop]# cat slaves
slaver01
slaver02

</property>
<property>

</property>
编辑conf/slaves,加入所有slaves／datanodes的主机名（或IP）,每个主机名占一行，此处即为
slaver01
slaver02
把namenode机器上配置好的hadoop安装包复制到其他的datanode机器上：
$scp-r /hadoop-2.2.0root@slaver01:/root
$scp-r /hadoop-2.2.0root@slaver02:/root
--------------------因为配置了环境变量，此处不需要输入hadoop命令的全路径/hadoop/bin/hadoop
执行后的结果中会提示“ dfs/namehas been successfully formatted”。否则格式化失败。
启动hadoop：
cd ~/hadoop-2.2.0/
./sbin/start-dfs.sh
./sbin/start-yarn.sh
启动成功后，分别在namenode和datanode所在机器上使用jps 命令查看，会在namenode所在机器上看到namenode,secondaryNamenode, ResourceManager
[root@masterhadoop-2.2.0]# jps
3066Jps
2672SecondaryNameNode
2532NameNode
2806ResourceManager
会在datanode1所在机器上看到datanode，tasktracker.否则启动失败，检查配置是否有问题。
[root@masterhadoop-2.2.0]# ssh slaver01
Lastlogin: Fri Jan 31 00:43:37 2014 from master
[root@slaver01~]# jps
2543Jps
2465NodeManager
2399DataNode
datanode1所在机器上看到datanode，NodeManager.
查看集群状态：

[root@master hadoop-2.2.0]#
目录(?)[+]
hadoop安装包：hadoop-2.2.0.tar.gz
操作系统： CentOS6.4
jdk版本： jdk1.7.0_21
1. 配置namenode和datanode
配置成功的关键在于确保各机器上的主机名和IP地址之间能正确解析。修改每台机器的/etc/hosts文件，如果该台机器作namenode用，则需要在文件中添加集群中所有机器的IP地址及其对应 主机名；如果该台机器仅作为datanode用，则只需要在文件中添加本机和namenode的IP地址及其对应的主机名。（修改主机名的命令为：hostname新名称）
1.1 master主机名称修改
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master
1.2 slaver01主机名称修改
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=slaver01
1.3 slaver02主机名称修改
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=slaver02
将上面两个文件修改完后，并不能立刻生效。如果要立刻生效的话，可以用 hostname your-hostname 作临时修改，它只是临时地修改主机名，系统重启后会恢复原样的。但修改上面两个文件是永久的，重启系统会得到新的主机名。
重启后查看主机名 uname
-n
1.4 修改hosts文件
假设有三台机器，主机名分别为master,slaver01,slaver02,IP地址为192.168.142.129,192.168.142.130,192.168.142.131，
master作为namenode，
slaver01,slaver02作为datanode，刚两者的hosts文件配置是一样的，如下：
[root@slaver02~]# cat /etc/hosts
192.168.159.129 master
192.168.159.130 slaver01
192.168.159.131 slaver02
2. ssh配置
该配置主要是为了实现在机器间执行指令时不需要输入密码。在namenode上执行以下命令：$cd ~/.ssh
$ssh-keygen -t rsa
--------------------然后一直按回车键，就会按照默认的选项将生成的密钥保存在.ssh/id_rsa文件中。
catid_rsa.pub > authorized_keys
在各个节点的authorized_keys生成
然后合并各个节点生成的密钥
cd.ssh
scproot@slaver01:/root/.ssh/authorized_keys authorized_keys_from_slaver01
scproot@slaver02:/root/.ssh/authorized_keys authorized_keys_from_slaver02
catauthorized_keys_from_slaver01 authorized_keys_from_slaver02>>authorized_keys
这个就是合并后的authorized_keys文件。
把刚刚产生的authorized_keys文件拷一份到datanode上.
scpauthorized_keys root@slaver01:/root/.ssh/
scpauthorized_keysroot@slaver02:/root/.ssh/
------
最后进入所有机器的.ssh目录，改变authorized_keys文件的许可权限。
$chmod 644 authorized_keys
这时从namenode所在机器向其他datanode所在机器发起ssh连接，只有在第一次登录时需要输入密码，以后则不需要。
3. 在所有机器上配置hadoop
首先在namenode所在机器上配置,执行如下解压命令:$ tar–xzvfhadoop-2.2.0.tar.gz--------------解压
解压完成后，编辑配置文件，这里要涉及到的配置文件有7个：
~/hadoop-2.2.0/etc/hadoop/hadoop-env.sh
exportJAVA_HOME=/usr/java/jdk1.7.0_21
~/hadoop-2.2.0/etc/hadoop/yarn-env.sh
exportJAVA_HOME=/usr/java/jdk1.7.0_21
~/hadoop-2.2.0/etc/hadoop/slaves
[root@masterhadoop]# cat slaves
slaver01
slaver02
~/hadoop-2.2.0/etc/hadoop/core-site.xml
<property>
<name>fs.defaultFS</name>
<value>hdfs://master:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/usr/dfs/tmp</value>
</property>
~/hadoop-2.2.0/etc/hadoop/hdfs-site.xml
<property>
<name>dfs.replication</name>
<value>2</value>
</property>
~/hadoop-2.2.0/etc/hadoop/mapred-site.xml
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
<property>
<name>mapreduce.jobhistory.address</name>
<value>master:10020</value>
</property>
<property>
<name>mapreduce.jobhistory.webapp.address</name>
<value>master:19888</value>
</property>
~/hadoop-2.2.0/etc/hadoop/yarn-site.xml
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
<property>
<name>yarn.resourcemanager.address</name>
<value>master:8032</value>
</property>
<property>
<name>yarn.resourcemanager.scheduler.address</name>
<value>master:8030</value>
</property>
<property>
<name>yarn.resourcemanager.resource-tracker.address</name>
<value>master:8031</value>
</property>
<property>
<name>yarn.resourcemanager.admin.address</name>
<value>master:8033</value>
</property>
<property>
<name>yarn.resourcemanager.webapp.address</name>
<value>master:8088</value>
</property>
编辑conf/slaves,加入所有slaves／datanodes的主机名（或IP）,每个主机名占一行，此处即为
slaver01
slaver02
把namenode机器上配置好的hadoop安装包复制到其他的datanode机器上：
$scp-r /hadoop-2.2.0root@slaver01:/root
$scp-r /hadoop-2.2.0root@slaver02:/root
4.格式化分布式文件系统，启动守护进程的命令如下：
$hadoop namenode format--------------------因为配置了环境变量，此处不需要输入hadoop命令的全路径/hadoop/bin/hadoop
执行后的结果中会提示“ dfs/namehas been successfully formatted”。否则格式化失败。
启动hadoop：
cd ~/hadoop-2.2.0/
./sbin/start-dfs.sh
./sbin/start-yarn.sh
启动成功后，分别在namenode和datanode所在机器上使用jps 命令查看，会在namenode所在机器上看到namenode,secondaryNamenode, ResourceManager
[root@masterhadoop-2.2.0]# jps
3066Jps
2672SecondaryNameNode
2532NameNode
2806ResourceManager
会在datanode1所在机器上看到datanode，tasktracker.否则启动失败，检查配置是否有问题。
[root@masterhadoop-2.2.0]# ssh slaver01
Lastlogin: Fri Jan 31 00:43:37 2014 from master
[root@slaver01~]# jps
2543Jps
2465NodeManager
2399DataNode
datanode1所在机器上看到datanode，NodeManager.
查看集群状态：
[root@master tmp]# hdfs namenode format
