2.4. 配置网络

2.4.1. 配置hosts

配置hosts文件的作用，它主要用于确定每个结点的IP地址，方便后续master结点能快速查到并访问各个节点。在3个虚机节点上均需要配置此文件：

在master、node1、node2中分别添加
主机名	IP址址		子网	网络类型	解析方式
Eth0	10.10.36.100		255.255.255.0	公用网络
/etc/hosts
10.10.36.100 master		NameNode
10.10.36.101 node1		DataNode
10.10.36.123 node2		DataNod

2.4.2. 配置网络

通过ifdown,ifup使配置的IP生效:

[root@master /]# sudo ifconfig eth0 10.10.36.100 netmask 255.255.255.0 up

[root@master /]# ifup eth0

Active connection state: activated

Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/4

[root@master /]#

[root@node1 /]# sudo ifconfig eth0 10.10.36.101 netmask 255.255.255.0 up

[root@node1 /]# ifup eth0

Active connection state: activated

Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/4

[root@node1 /]#

[root@node2 /]# sudo ifconfig eth0 10.10.36.123 netmask 255.255.255.0 up

[root@node2 /]# ifup eth0

Active connection state: activated

Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/3

[root@node2 /]# ifconfig -a

eth0 Link encap:Ethernet HWaddr 00:0C:29:57:08:7B

[root@node2 /]#

2.5. 配置资源与参数

2.5.1. 修改主机名称

[root@master /]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=master

[root@node1 /]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=node1

[root@node2 /]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=node2

2.5.2. 配置用户,组,目录和权

　　为hadoop集群专门设置一个用户组及用户，这部分比较简单，参考示例如下：

　　sudo groupadd hadoop //设置hadoop用户组

　　sudo useradd –s /bin/bash –d /home/uhadoop –m uhadoop –g hadoop –G admin //添加一个uhadoop用户，此用户属于　　hadoop用户组，且具有admin权限。

3个虚机节点均需要进行以上步骤来完成hadoop运行帐号的建立。

[root@master /]# sudo groupadd hadoop

[root@master /]# sudo groupadd admin

[root@master /]# sudo useradd -s /bin/bash -d /home/uhadoop -m uhadoop -g hadoop -G admin [root@master /]# echo -n uhadoop|passwd --stdin uhadoop

Changing password for user uhadoop.

passwd: all authentication tokens updated successfully.

[root@node1 /]# sudo groupadd hadoop

[root@node1 /]# sudo groupadd admin

[root@node1 /]# sudo useradd -s /bin/bash -d /home/uhadoop -m uhadoop -g hadoop -G admin

[root@node1 /]# echo -n uhadoop|passwd --stdin uhadoop

Changing password for user uhadoop.

passwd: all authentication tokens updated successfully.

[root@node2 /]# sudo groupadd hadoop

[root@node2 /]# sudo groupadd admin

[root@node2 /]# sudo useradd -s /bin/bash -d /home/uhadoop -m uhadoop -g hadoop -G admin

[root@node2 /]# echo -n uhadoop|passwd --stdin uhadoop

Changing password for user uhadoop.

passwd: all authentication tokens updated successfully.

2.5.3. 修改系统内核参数/etc/sysctl.conf

[root@linuxrac1 etc]# vi sysctl.conf

# add parameter for oracle

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 1073741824

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048586

2.6. 配置等效性与连通(可选项)

2.6.1. uhadoop用户等效性

1.以下均以uhadoop用户执行: 在两个节点的grid主目录分别创建.ssh目录，并赋予权限

3.1.2. 添加hadoop环境变量

在三个节点都添加环境变量

[root@master /]# vi /etc/profile

# set environment by HondaHsu 2014

JAVA_HOME=/usr/java/jdk1.8.0_25

JRE_HOME=/usr/java/jdk1.8.0_25/jre

HADOOP_HOME=/home/uhadoop/uhadoop/hadoop-2.5.2

HADOOP_COMMON_HOME=$HADOOP_HOME

HADOOP_HDFS_HOME=$HADOOP_HOME

HADOOP_MAPRED_HOME=$HADOOP_HOME

HADOOP_YARN_HOME=$HADOOP_HOME

HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop

PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tool.jar:$JRE_HOME/lib:$HADOOP_HOME/lib

export JAVA_HOME JRE_HOME PATH CLASSPATH

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native

export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

[root@master /]# source /etc/profile

3.1.3. 修改Hadoop配置文件(所有节点相同)

（1）core-site.xml

[uhadoop@master hadoop]$ cd /home/uhadoop/uhadoop/hadoop-2.5.2/etc/hadoop

[uhadoop@master hadoop]$ vi core-site.xml

<property>

<name>hadoop.tmp.dir</name>

<value>/home/uhadoop/uhadoop/hadoop-2.5.2/tmp</value>

<description>A base for other temporary directories.</description>

</property>

<property>

<value>hdfs://master:9000</value>

</property>

<property>

<name>io.file.buffer.size</name>

<value>131072</value>

</property>

<property>

<name>hadoop.proxyuser.root.hosts</name>

<value>namenode</value>

</property>

<property>

<name>hadoop.proxyuser.root.groups</name>

<value>*</value>

</property>

</configuration>

（2）hdfs-site.xml

[uhadoop@master hadoop]$ vi hdfs-site.xml

<property>

<name>dfs.namenode.secondary.http-address</name>

<value>master:50090</value>

</property>

<property>

<value>/home/uhadoop/uhadoop/hadoop-2.5.2/hdfs/name</value>

<final>true</final>

</property>

<property>

<name>dfs.datanode.data.dir</name>

<value>/home/uhadoop/uhadoop/hadoop-2.5.2/hdfs/data</value>

<final>true</final>

</property>

<property>

<name>dfs.replication</name>

<value>2</value>

</property>

<property>

<name>dfs.permissions</name>

<value>false</value>

</property>

</configuration>

（3）mapred-site.xml

[uhadoop@master hadoop]$ cp mapred-site.xml.template mapred-site.xml

[uhadoop@master hadoop]$ vi mapred-site.xml

<property>

<name>mapreduce.framework.name</name>

<value>yarn</value>

</property>

<property>

<name>mapreduce.jobtracker.http.address</name>

<value>master:50030</value>

</property>

<property>

<value>master:19888</value>

</property>

<property>

<name>mapreduce.jobhistory.intermediate-done-dir</name>

<value>/mr-history/tmp</value>

</property>

<property>

<name>mapreduce.jobhistory.done-dir</name>

<value>/mr-history/done</value>

</property>

</configuration>

--------------------------------------------------------

jobhistory是Hadoop自带了一个历史服务器，记录Mapreduce历史作业。默认情况下，jobhistory没有启动，可用以下命令启动：

sbin/mr-jobhistory-daemon.sh start historyserver

---------------------------------------------------------

（4）yarn-site.xml

<property>

<name>Yarn.nodemanager.aux-services</name>

<value>mapreduce.shuffle</value>

</property>

<property>

<name>Yarn.resourcemanager.address</name>

<value>master:18040</value>

</property>

<property>

<name>Yarn.resourcemanager.scheduler.address</name>

<value>master:18030</value>

</property>

<property>

<value>/home/uhadoop/uhadoop/hadoop-2.5.2/mynode/my</value>

</property>

<property>

<name>Yarn.nodemanager.log.retain-seconds</name>

<value>10800</value>

</property>

<property>

<name>Yarn.nodemanager.remote-app-log-dir</name>

<value>/logs</value>

</property>

<property>

<name>Yarn.nodemanager.remote-app-log-dir-suffix</name>

<value>logs</value>

</property>

<property>

<name>Yarn.log-aggregation.retain-seconds</name>

<value>-1</value>

</property>

<property>

<name>Yarn.log-aggregation.retain-check-interval-seconds</name>

<value>-1</value>

</property>

</configuration>

（5）slaves

[uhadoop@master hadoop]$ vi slaves

node1

node2

（6）修改JAVA_HOME: 分别在文件hadoop-env.sh和yarn-env.sh中添加JAVA_HOME配置

[uhadoop@master hadoop]$ vi hadoop-env.sh

export JAVA_HOME=/usr/java/jdk1.8.0_25

或export JAVA_HOME=${JAVA_HOME}

[uhadoop@master hadoop]$ vi yarn-env.sh

export JAVA_HOME=/usr/java/jdk1.8.0_25

或export JAVA_HOME=${JAVA_HOME}

3.1.4. 格式化文件系统

格式化文件系统：

[uhadoop@master ~]$ cd /home/uhadoop/uhadoop/hadoop-2.5.2/bin

[uhadoop@master bin]$ hdfs namenode -format

5.2. 常用命令

常用命令：

hadoop dfs -ls 列出HDFS下的文件
hadoop dfs -ls in 列出HDFS下某个文档中的文件
hadoop dfs -put test1.txt test 上传文件到指定目录并且重新命名，只有所有的DataNode都接收完数据才算成功
hadoop dfs -get in getin 从HDFS获取文件并且重新命名为getin，同put一样可操作文件也可操作目录
hadoop dfs -rmr out 删除指定文件从HDFS上
hadoop dfs -cat in/* 查看HDFS上in目录的内容
hadoop dfsadmin -report 查看HDFS的基本统计信息，结果如下
hadoop dfsadmin -safemode leave 退出安全模式
hadoop dfsadmin -safemode enter 进入安全模式
