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.############################## [hadoop@master hadoop]$ cat core-site.xml <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

9.分发到slave节点
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 节点测试
/home/hadoop/name1 /home/hadoop/name2 /home/hadoop/name3 这三个目录不要创建，如果创建会提示 重新reload cd /home/hadoop/hadoop-2.7.0 [hadoop@master hadoop-2.7.0]$ ./bin/hadoop namenode -format DEPRECATED: Use of this script to execute hdfs command is deprecated.
