Hadoop 安装配置

1.创建用户组和用户

groupadd hadoops  
useradd hadoop -g hadoops
passwd hadoop

2.解压jdk和hadoop

tar -zxvf jdk1.7.0_80.tar.gz -C /usr/local
mv /usr/local/jdk1.7.0_80 /usr/local/java

tar -zxvf hadoop-2.7.3.tar.gz -C /u01
mv /u01/hadoop-2.7.3  /u01/hadoop

chown -R hadoop:hadoop /u01/hadoop/etc/hadoop/**
chown -R hadoop:hadoop /u01/hadoop/bin/**
chown -R hadoop:hadoop /u01/hadoop/sbin/**

3.配置环境变量

vi /etc/profile

export HADOOP_HOME=/u01/hadoop
export PATH=$HADOOP_HOME/bin:$PATH
export JAVA_HOME=/usr/local/java
export PATH=$JAVA_HOME/bin:$PATH

source /etc/profile

4.配置hosts

vi /etc/hosts

192.168.0.9 hadmaster
192.168.0.27 hadslave1
192.168.0.28 hadslave2

5.创建目录

mkdri /u01/hadoopData
chown hadoop:hadoop /u01/hadoopData

vi /u01/hadoop/etc/hadoop/slaves

hadslave1
hadslave2

vi /u01/hadoop/etc/hadoop/masters
hadmaster

6.配置hadoop

  • 6.1.编辑hadoop-env.sh

    vi /u01/hadoop/etc/hadoop/hadoop-env.sh

export JAVA_HOME=/usr/local/java
export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true

<property>
    <name>dfs.namenode.name.dir</name>
    <value>file:/u01/hadoopData/name,file:/u01/hadoopData/name2</value>
</property>

  • 6.4.编辑mapred-site.xml

    cp /u01/hadoop/etc/hadoop/mapred-site.xml.template  /u01/hadoop/etc/hadoop/mapred-site.xml
