Hadoop集群搭建笔记

[日期:2016-09-07] 来源:天善智能  作者: [字体: ]

1、安装虚拟机

VMware workstation

CentOS 镜像

安装Linux虚拟机:(在Win7上)

1)安装VMwareWorkstations(可修改配置)

2)添加CentOS镜像(启动安装 ->配置网络)

网络配置:NAT模式

网络重启:service network restart

关闭系统:shutdown -h now

Hadoop

2、远程连接

Xshell5

Xftp5

3、在Linux上搭建Hadoop集群

下载软件

1. Jdk: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

2. Hadoop包: http://apache.fayea.com/hadoop/common/hadoop-2.7.2/

步骤:

1、修改/etc/hosts

2、配置JDK

安装:rpm -ivh jdk-8u101-linux-x64.rpm

vi /etc/profile

JAVA_HOME

source /etc/profile

java -version

3、配置SSH(免密码登录)

ssh-keygen -t rsa

cat xxx.pub >> authorized_keys

chmod 644 authorized_keys

ssh IP/HOSTNAME

4、安装及配置Hadoop

tar zxf hadoop-2.7.2.tar.gz

cd /opt/hadoop-2.7.2/etc/hadoop/

slaves

bigdata

JAVA_HOME

5、格式化HDFS

hdfsnamenode -format

‘16/09/0403:07:30 INFO common.Storage: Storage directory /opt/hadoop-2.7.2/current/dfs/namehas been successfully formatted.’

6、启动Hadoop集群

/opt/hadoop-2.7.2/sbin/start-all.sh

7、验证Hadoop集群

1)jps

2)

关闭防火墙 或者 在防火墙的规则中开放这些端口

hdfs  http://bigdata:50070

yarn  http://bigdata:18088
