2017-11-21 641

1.基础环境

 
         [hadoop@master ~]$ 
         cat  
         /etc/redhat-release 
        
         CentOS Linux release 7.2.1511 (Core) 
        
         [hadoop@master ~]$ 
        
         [hadoop@master ~]$ getenforce 
        
         Disabled
        
         [hadoop@master ~]$ systemctl  status  firewalld 
        
         ● firewalld.service - firewalld - dynamic firewall daemon
        
         Loaded: loaded (
         /usr/lib/systemd/system/firewalld
         .service; disabled; vendor preset: enabled) 
        
         Active: inactive (dead) 
        
         [hadoop@master ~]$

2.IP以及对应节点

IP	主机名	hadoop node	hadoop 进程名称
192.168.56.100	master	master	namenode,jobtracker
192.168.56.101	slave1	slave	datanode,tasktracker
192.168.56.102	slave2	slave	datanode,tasktracker
192.168.56.103	slave3	slave	datanode,tasktracker

 
         [hadoop@master ~]
         # cat  /etc/hosts 
        
         192.168.56.100  Master
        
         192.168.56.101  slave1
        
         192.168.56.102  slave2
        
         192.168.56.103  slave3
        
         [hadoop@master ~]
         #

3.增加hadoop用户，所有节点

 
         useradd  
         hadoop 
        
         echo 
         hadoop|
         passwd  
         --stdin  hadoop

4.jdk

 
         [hadoop@slave1 application]
         # ll 
        
         total 4
        
         lrwxrwxrwx 1 root root   24 Jul 10 01:35 jdk -> 
         /application/jdk1
         .8.0_60 
        
         drwxr-xr-x 8 root root 4096 Aug  5  2015 jdk1.8.0_60
        
         [hadoop@slave1 application]
         # pwd 
        
         /application
        
         [hadoop@slave1 application]
         #  
        
         [hadoop@master ~]
         # java  -version  
        
         java version 
         "1.8.0_60" 
        
         Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
        
         Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
        
         [hadoop@master ~]
         #

5.master(192.168.56.100)上的hadoop用户可以ssh所有slave节点的hadoop用户下

6.设置hadoop安装路径以及环境变量（所有节点）

 
         su  
         -  hadoop 
        
         tar 
         xf  hadoop-2.7.0tar.gz 
        
         /home/hadoop/hadoop-2
         .7.0 
        
         vi 
         /etc/profile  
         添加hadoop环境变量 
        
         export 
         HADOOP_HOME=
         /home/hadoop/hadoop-2
         .7.0 
        
         export 
         PATH=$PATH:$HADOOP_HOME
         /bin 
        
         source 
         /etc/profile

7.修改hadoop的环境的Java环境变量

 
         /home/hadoop/hadoop-2
         .7.0
         /etc/hadoop 
        
         vi 
         hadoop-
         env
         .sh 添加 
        
         ###JAVA_HOME
        
         export 
         JAVA_HOME=
         /application/jdk/

8.修改hadoop的配置文件

 
         cd  
         /home/hadoop/hadoop-2
         .7.0
         /etc/hadoop 
        
         1.

10.master 节点测试
