hadoop的部署以及應用

1.基礎環境

[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以及對應節點

[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用戶，所有節點

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用戶可以ssh所有slave節點的hadoop用戶下

6.設置hadoop安裝路徑 以及環境變量（所有節點）

su  -  hadoop
tar xf  hadoop-2.7.0tar.gz
/home/hadoop/hadoop-2.7.0
vi /etc/profile  添加hadoop環境變量
export HADOOP_HOME=/home/hadoop/hadoop-2.7.0
export PATH=$PATH:$HADOOP_HOME/bin
source /etc/profile

7.修改hadoop的環境的Java環境變量

/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

9.分發到slave節點

scp   -r  /home/hadoop/hadoop-2.7.0  slave1:/home/hadoop/
scp   -r  /home/hadoop/hadoop-2.7.0  slave2:/home/hadoop/
scp   -r  /home/hadoop/hadoop-2.7.0  slave3:/home/hadoop/

10.master 節點測試

/home/hadoop/name1 /home/hadoop/name2  /home/hadoop/name3  這三個目錄不要創建，如果創建會提示
重新reload

cd  /home/hadoop/hadoop-2.7.0
[hadoop@master hadoop-2.7.0]$ ./bin/hadoop namenode -format
