一,搭建大数据集群环境
(由于内容过多分为了4个博客,后面有链接分享,也可去我的主页查看)
1.1安装准备
1.1.1虚拟机安装与克隆
1.虚拟机的安装和设置以及启动虚拟机并安装操作系统
安装一台虚拟机主机名为:hadoop01的虚拟机备用(以下仅供参考)

2.克隆虚拟机
克隆两台虚拟机主机名分别为:hadoop02、hadoop03备用。(以下仅供参考)

1.1.2虚拟机网络配置
1.主机名与ip映射配置
开启三台虚拟机
分别在hadoop01、hadoop02、hadoop03中输入root 和自己设置的root用户密码进入root用户
(1)修改主机名(三台分别改为hadoop01、hadoop02、hadoop03)
vi /etc/sysconfig/network
(2)配置ip
查看当前虚拟机的ip(编辑--->虚拟网络编辑器)
每个人的ip可能都不一样,我的是192.168.80.0,自己做的时候需要修改为自己的ip
修改ip:vi /etc/sysconfig/network-scripts/ifcfg-ens33
hadoop01的IPADDR=192.168.80.131
hadoop02的IPADDR=192.168.80.132
hadoop03的IPADDR=192.168.80.133
其他的都一样
(3)ip 映射
vi /etc/hosts
三台都是一样的
192.168.80.131 hadoop01
192.168.80.132 hadoop02
192.168.80.133 hadoop03
(4)配置效果检验
1.1.3 SSH服务配置
1 SSH 远程登录功能配置
为了方便操作和更美观,我使用finalshell远程操作虚拟机(以下仅供参考)

2 SSH免密登录功能配置
(1)在三台虚拟机中分别执行以下命令:
ssh-keygen -t rsa 一直输入回车即可
(2)在三台虚拟机中分别执行以下命令:
ssh-copy-id hadoop01 输入yes和密码即可
(3)在Hadoop01上将文件/root/.ssh/authorized_keys发送给Hadoop02和Hadoop03
scp /root/.ssh/authorized_keys hadoop02:/root/.ssh
scp /root/.ssh/authorized_keys hadoop03:/root/.ssh
