hadoop实战之分布式模式

环境

192.168.1.101 host101
192.168.1.102 host102

1.安装配置host101

[root@host101 ~]# cat /etc/hosts |grep 192
192.168.1.101   host101
192.168.1.102   host102
[root@host101 ~]# rpm -ivh jdk-8u91-linux-x64.rpm
[root@host101 ~]# tar -zxvf hadoop-2.6.4.tar.gz
[root@host101 ~]# mv hadoop-2.6.4 /usr/local/hadoop
[root@host101 ~]# cd /usr/local/hadoop/
[root@host101 hadoop]# vim etc/hadoop/hadoop-env.sh
export JAVA_HOME=/usr/java/latest
export HADOOP_PREFIX=/usr/local/hadoop
[root@host101 hadoop]# vim etc/hadoop/slaves
host101
host102
[root@host101 hadoop]# vim etc/hadoop/core-site.xml
<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://host101:9000</value>
    </property>
</configuration>
 
[root@host101 hadoop]# mkdir -p /hadoop/
[root@host101 hadoop]# vim etc/hadoop/hdfs-site.xml
<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>/hadoop/name/</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>/hadoop/data/</value>
    </property>
</configuration>
[root@host101 hadoop]# vim mapred-site.xml
<configuration>
  <property>
      <name>mapred.job.tracker</name>
      <value>host101:9001</value>
  </property>
</configuration>
[root@host101 ~]# ssh-keygen
[root@host101 ~]# ssh-copy-id host101
[root@host101 ~]# ssh-copy-id host102

2.安装配置host102

[root@host102 ~]# scp host101:/root/hadoop-2.6.4.tar.gz .
[root@host102 ~]# scp host101:/root/jdk-8u91-linux-x64.rpm .
 
[root@host102 ~]# rpm -ivh jdk-8u91-linux-x64.rpm
[root@host102 ~]# tar -zxvf hadoop-2.6.4.tar.gz
[root@host102 ~]# mv hadoop-2.6.4 /usr/local/hadoop
[root@host102 ~]# ssh-keygen
[root@host102 ~]# ssh-copy-id host101
[root@host102 ~]# ssh-copy-id host102
[root@host102 etc]# cd /usr/local/hadoop/etc/hadoop/
[root@host102 hadoop]# scp host101:/usr/local/hadoop/etc/hadoop/mapred-site.xml .
[root@host102 hadoop]# scp host101:/usr/local/hadoop/etc/hadoop/slaves .
[root@host102 hadoop]# scp host101:/usr/local/hadoop/etc/hadoop/hdfs-site.xml .
[root@host102 hadoop]# scp host101:/usr/local/hadoop/etc/hadoop/hadoop-env.sh .
[root@host102 hadoop]# scp host101:/usr/local/hadoop/etc/hadoop/core-site.xml .

3.启动hadoop集群

[root@host101 hadoop]# sbin/start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [host101]
