Hadoop-2.7.1完全分布式集群搭建完整版

系统配置

使用的Linux系统:

CentOS 6.5

Hots

192.168.22.190 nn1

192.168.22.191 dn1

192.168.22.192 dn2

 

使用到的Hadoop为

Hadoop-2.7.1.tar.gz

 

系统配置 nn1,dn1,dn2都要配置

关闭防火墙

chkconfig iptables off

 

vim /etc/sysconfig/selinux

修改enforcing为disabled

修改ip地址

可以手动修改也可以使用命令操作

Vim   /etc/sysconfig/network-scripts/ifcfg-eth0

 

vim /etc/sysconfig/network

 

配置好网络后重启 network

service network restart

 

 

修改 hosts

vim /etc/hosts

192.168.22.130 nn1

192.168.22.131 dn1

192.168.22.132 dn2

 

新建hadoop用户

Useradd hadoop

Userpasswod 修改hadoop密码

Su hadoop 切换hadoop用户

 

配置ssh免密码登录

在nn1,dn1,dn2都要执行(登录hadoop用户执行)

刚开始 hadoop 用户根目录下没有 .ssh 这个隐藏目录,我们可以自己创建mkdir ~/.ssh

chown hadoop.hadoop -R /home/hadoop/.ssh

chmod 755 /home/hadoop/.ssh

然后执行命令 生成 ssh 密匙

ssh-keygen -t rsa

然后一路回车,如图

 

则会在.ssh这个隐藏的目录下生成连个文件

id_rsa(私钥)和id_rsa.pub(公钥)

我们需要将id_rsa.pub(公钥)的信息加入到authorized_keys(需要自己创建)文件里面

Cd ~/.ssh

注:执行完以后将 dn1 和 dn2 的id_rsa.pub(公钥) copy到nn1中

如

[hadoop@dn1 .ssh] scp id_rsa.pub [email protected]:~/.ssh/dn1

[hadoop@dn2 .ssh] scp id_rsa.pub [email protected]:~/.ssh/dn2

 

 

JDK配置HOME

注:直接在创建 /usr目录下会提示

hadoop is not in the sudoers file.  This incident will be reported

所以切换成 su root

修改sudoers

vim /etc/sudoers

在 root    ALL=(ALL)       ALL下面添加一条

hadoop    ALL=(ALL)       ALL

 

Ok

退出 root用户

Exit

使用 hadoop 用户在 /usr目录下创建 jvm文件夹存放 jdk

Sudo /usr/jvm

解压jdk,我的jdk存放在Downloads目录下

sudo tar zxvf ~/Downloads/jdk-7u67-linux-i586.tar.gz -C /usr/jvm/

设置环境变量

Vim /etc/profile

 

添加以后使用source /etc/profile更新profile

使用命令java提示出以下信息说明成功了

 

新建hadoop工作目录以及读写权限

mkdir  /home/hadoop/src (存放hadoop/Flume/hbase安装目录)

 

配置Hadoop集群

解压hadoop 2.7.1 到 hadoop/src 目录下

tar -zxvf ~/Downloads/hadoop-2.7.1.tar.gz -C /home/hadoop/src/

配置HADOOP_HOME环境变量

 

 

配置 hadoop-env.sh core-site.xml hdfs-site.xml yarn-site.xml mapred-site.xml(开始是不存在的需要将mapred-site.xml.template cp 一份为 mapred-site.xml)

 

vim hadoop-env.sh

 

vim core-site.xml

 
        

                fs.defaultFS
                hdfs://nn1:9000
        
 
 
        

                hadoop.tmp.dir
                file:/home/hadoop/src/hadoop-2.7.1/
        
 

vim hdfs-site.xml

 
        
                dfs.namenode.name.dir
                file:/home/hadoop/src/hadoop-2.7./tmp/dfs/name
        
 
        
                dfs.datanode.data.dir
                file:/home/hadoop/src/hadoop-2.7.1/tmp/dfs/date
        
        
           dfs.replication
            3
        
 
        
                dfs.replication
                3
        
 

Vim mapred-site.xml

Cp mapred-site.xml.template mapred-site.xml

Vim mapred-site.xml

  mapreduce.framwork.name
  yarn

 

Vim yarn-site.xml

 

  yarn.resourcemanager.hostname
  nn1

 

 

vim slaves

添加dn1和dn2

 

配置完成,scp到节点(dn1 da2)上接下来在nn1上格式化HDFS

hdfs namenode -format
