hadoop2.7.0版本搭建伪分布式环境

来源：互联网发布：jquery.ajaxqueue.js 编辑：程序博客网时间：2024/05/21 08:59

1.安装好SUSE 11系统，配置IP，

2，创建用户hadoop，属组，修改权限；

useradd命令详解（实例） 1.作用useradd命令用来建立用户帐号和创建用户的起始目录，使用权限是终极用户。2.格式useradd [－d home] [－s shell] [－c comment] [－m [－k template]] [－f inactive] [－e expire ] [－p passwd] [－r] name3.主要参数－c：加上备注文字，备注文字保存在passwd的备注栏中。　－d：指定用户登入时的启始目录。－D：变更预设值。－e：指定账号的有效期限，缺省表示永久有效。－f：指定在密码过期后多少天即关闭该账号。－g：指定用户所属的群组。－G：指定用户所属的附加群组。－m：自动建立用户的登入目录。－M：不要自动建立用户的登入目录。－n：取消建立以用户名称为名的群组。－r：建立系统账号。－s：指定用户登入后所使用的shell。－u：指定用户id号。4.说明useradd可用来建立用户账号，他和adduser命令是相同的。账号建好之后，再用passwd设定账号的密码。使用useradd命令所建立的账号，实际上是保存在/etc/passwd文本文件中。5.应用实例建立一个新用户账户，并设置id：＃useradd caojh －u 544需要说明的是，设定id值时尽量要大于500，以免冲突。因为Linux安装后会建立一些特别用户，一般0到499之间的值留给bin、mail这样的系统账号。

userad -u 501 -g users -d /home/hadoop -s /bin/bash hadoop

chown -R hadoop:users /home/hadoop

passwd hadoop

3.修改主机名

通过修改配置文件的方式并运行命令修改主机名
修改/etc/HOSTNAME文件，在此文件中保存主机名，例如：
BDmanerger

然后运行命令设置主机名
# /etc/rc.d/boot.localnet start

vi /etc/hosts

127.0.0.1 marster localhost

4.创建ssh密钥

ssh-keygen -t rsa 一路回车

cd .ssh/

cat id_rsa.pub >> authorized_keys

chmod 600 authorized_keys

chmod 700 .ssh/

5.安装JDK，

下载jdk-7u79-linux-x64.rpm

rpm -qa |grep java

rpm -e java当前版本

rpm -ivh jdk-7u79-linux-x64.rpm

配置jdk环境变量

#java env
export JAVA_HOME=/usr/java/jdk1.7.0_79/
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin/:$PATH

记得source一下哦

6.安装hadoop2.7

下载hadoop-2.7.1版本http://apache.fayea.com/hadoop/common/hadoop-2.7.1/

解压hadoop tar -zxvf hadoop-2.7.1.tar.gz

配置hadoop环境变量

#hadoop env
export HADOOP_HOME=/home/hadoop/hadoop-2.7.1/
export PATH=$HADOOP_HOME/bin/:$PATH

记得source一下哦，验证一下

hadoop@marster:~> hadoop
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
credential interact with credential providers
Hadoop jar and the required libraries
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.

接下来在/home/hadoop/hadoop-2.7.1/下创建dfs/name和dfs/data目录

marster:/home/hadoop/hadoop-2.7.1 # ls
LICENSE.txt NOTICE.txt README.txt bin dfs etc include lib libexec logs sbin share tmp
marster:/home/hadoop/hadoop-2.7.1 # cd dfs/
marster:/home/hadoop/hadoop-2.7.1/dfs # ls
data name

接下来要在hadoop-2.7.1/etc/hadoop修改配文件：

hadoop-env.sh

# The java implementation to use.
export JAVA_HOME=/usr/java/jdk1.7.0_79/

mapred-env.sh

# export JAVA_HOME=/home/y/libexec/jdk1.6.0/
export JAVA_HOME=/usr/java/jdk1.7.0_79/

yarn-env.sh

# export JAVA_HOME=/home/y/libexec/jdk1.6.0/
export JAVA_HOME=/usr/java/jdk1.7.0_79/

接下来修改hadoop-2.7.1/etc/hadoop/slaves的名字为BDmanerger

接下来要配置

core-site.xml

<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://marster:9000</value>
<description>The name of the default file system</description>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hadoop/hadoop-2.7.1/tmp</value>
<description>A base of other temporaty directorries</description>
</property>
</configuration>

hdfs-site.xml

<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>/home/hadoop/hadoop-2.7.1/dfs/data</value>
</property>
</configuration>

yarn-site.xml

<configuration>


<property>
<name>yarn.resourcemanager.hostname</name>
<value>marster</value>
</property>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
</configuration>

7，启动并验证hadoop

hadoop@marster:~/hadoop-2.7.1/etc/hadoop> hadoop namenode -format
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

接下来启动HDFS

hadoop@marster:~/hadoop-2.7.1/sbin> ./start-dfs.sh
15/07/24 13:50:02 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Starting namenodes on [marster]

Starting secondary namenodes [0.0.0.0]

接下来验证一下

hadoop@marster:~/hadoop-2.7.1/sbin> jps
25796 NameNode
26140 SecondaryNameNode
26849 NodeManager
42645 Jps
25904 DataNode

通过web控制台查看HDFS,http://BDmanager:50070/dfshealth.html#tab-overview

接下来启动YARN

hadoop@marster:~/hadoop-2.7.1/sbin> ./start-yarn.sh
hadoop@marster:~/hadoop-2.7.1/sbin> jps
25796 NameNode
26140 SecondaryNameNode
26849 NodeManager
42645 Jps
25904 DataNode
26735 ResourceManager

hadoop web控制台页面的端口整理：

50070：hdfs文件管理

8088：ResourceManager

8042：NodeManager

19888：JobHistory(使用“mr-jobhistory-daemon.sh”来启动JobHistory Server)
