〇、所需资料
一、配置
1、基础配置
(1)系统安装
(2)hostname主机名配置
(3)ip地址、dns、hosts映射文件配置
(4)关闭防火墙与selinux
(5)开启ntpd时钟同步
(6)jdk安装与环境变量配置
(7)机器克隆、配置
(8)ssh免密设置
2、部署配置
(1)包含内容
(2)hadoop环境变量配置
vi /etc/profile
(3)etc/hadoop下配置-core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://hadoop01:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/var/bigdata/tmp/hadoop/full</value>
</property>
</configuration>
(4)etc/hadoop下配置-hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>2</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>/var/bigdata/hadoop/full/dfs/name</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>/var/bigdata/hadoop/full/dfs/data</value>
</property>
<property>
<name>dfs.namenode.secondary.http-address</name>
<value>hadoop02:50090</value>
</property>
<property>
<name>dfs.namenode.checkpoint.dir</name>
<value>/var/bigdata/hadoop/full/dfs/secondary</value>
</property>
</configuration>
(3)etc/hadoop下配置-slave配置dn
hadoop02
hadoop03
(4)目录分发到其他节点
scp -r ./hadoop/ hadoop02:pwd
二、启动
1、nn格式化
bin/hdfs namenode -format
2、启动dfs
sbin/start-dfs.sh
三、验证
1、nn验证
2、dn验证
3、页面验证
