Hadoop详细安装配置过程

1.下载并安装ubuntukylin-15.10-desktop-amd64.iso

2.安装ssh

sudo apt-get install openssh-server openssh-client

3.搭建vsftpd

#sudo apt-get update

#sudo apt-get install vsftpd

配置参考 .linuxidc./Linux/2015-01/111970.htm

vsftpd的开始、关闭和重启

$sudo /etc/init.d/vsftpd start #开始

$sudo /etc/init.d/vsftpd stop #关闭

$sudo /etc/init.d/vsftpd restart #重启

4.安装jdk1.7

sudo chown -R hadoop:hadoop /opt

cp /soft/jdk-7u79-linux-x64.gz /opt

sudo vi /etc/profile

alias untar='tar -zxvf'

sudo source /etc/profile

source /etc/profile

untar jdk*

环境变量配置

# vi /etc/profile

●在profile文件最后加上

# set java environment

export JAVA_HOME=/opt/jdk1.7.0_79

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$JAVA_HOME/bin:$PATH

配置完成后，保存退出。

●不重启，更新命令

#source /etc/profile

●测试是否安装成功

# Java –version

--------------------------------------------

克隆master虚拟机至node1 、node2

分别修改master的主机名为master、node1的主机名为node1、node2的主机名为node2 (启动node1、node2系统默认分配递增ip，无需手动修改)

分别修改/etc/hosts中的ip和主机名(包含其他节点ip和主机名)

---------

配置ssh免密码连入

hadoopnode1:~$ ssh-keygen -t dsa -P ''-f ~/.ssh/id_dsa Generating public/private dsa key pair.

Created directory '/home/hadoop/.ssh'.

Your identification has been saved in/home/hadoop/.ssh/id_dsa. Your public key has been saved in/home/hadoop/.ssh/id_dsa.pub. The key fingerprint is:

SHA256:B8vBju/uc3kl/v9lrMqtltttttCcXgRkQPbVoU hadoopnode1

The key's randomart image is:
