Hadoop3.3.6安装和配置hbase-2.5.5-hadoop3x,zookeeper-3.8.3_apache hadoop3.3.6

apache hadoop3.3.6

文章目录

前置配置

vm设置

image-20231121132727711

image-20231121132942277

虚拟机创建(hadoop1,hadoop2,hadoop3)

image-20231121133408764

在安装过程中推荐设置root用户密码为1234方面后续操作

image-20231121134710174

image-20231121135614905

linux前置配置(三个机器都要设置)

1.设置主机名

以hadoop3为例

hostnamectl set-hostname hadoop3

2.设置固定ip

vim  /etc/sysconfig/network-scripts/ifcfg-ens33

image-20231121142121714

image-20231121142345471

hadoop1 192.168.88.201

hadoop2 192.168.88.202

hadoop3 192.168.88.203

最后执行
service network restart
刷新网卡

3.工具连接(三个机器都要设置)

image-20231121143155954

4.主机映射

windows:

C:\Windows\System32\drivers\etc

修改这个路径下的hosts文件

image-20231121142801076

在这里插入图片描述

推荐使用vscode打开可以修改成功

linux:(三个机器都要设置)
vim /etc/hosts

image-20231121143328804

5.配置SSH免密登录(三个机器都要设置)

root免密
1.在每一台机器都执行:ssh-keygen -trsa -b 4096 ,一路回车到底即可

image-20231121144137560

2.在每一台机器都执行:
ssh-copy-id hadoop1
ssh-copy-id hadoop2
ssh-copy-id hadoop3

image-20231121144811918

hadoop免密

创建hadoop用户并配置免密登录

1.在每一台机器执行:useradd hadoop,创建hadoop用户
2.在每一台机器执行:passwd hadoop,设置hadoop用户密码为1234

image-20231121145056481

3.在每一台机器均切换到hadoop用户:su - hadoop,并执行ssh-keygen -trsa -b 4096,创建ssh密钥

image-20231121145136894

4.在每一台机器均执行
ssh-copy-id hadoop1
ssh-copy-id hadoop2
ssh-copy-id hadoop3

6.关闭防火墙和SELinux(三个机器都要设置)

1:
systemctl stop firewalld

systemctl disable firewalld

image-20231121145843188

2.
vim /etc/sysconfig/selinux 

image-20231121145940957

设置好输入 init 6 重启

image-20231121150154985

3.

以下操作在三台Linux均执行

  1. 安装ntp软件
yum install -y ntp
  1. 更新时区
rm -f /etc/localtime;sudo ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
  1. 同步时间
ntpdate -u ntp.aliyun.com
  1. 开启ntp服务并设置开机自启
systemctl start ntpd

systemctl enable ntpd

image-20231121150445744

三台创建快照1

image-20231121150549502

环境配置

1、jdk1.8 Java Downloads | Oracle

2、hadoop-3.3.6 Apache Hadoop

3、hbase-2.5.5.hadoop3x Index of /dist/hbase/2.5.5 (apache.org)

4、zookeeper-3.8.3 Apache ZooKeeper

重点:以下配置都是在root用户下进行配置后续会给对应的hadoop用户权限

推荐一口气配置完在进行给予权限和进行配置文件的刷新,以及最后的分发

jdk

创建文件夹,用来部署JDK,将JDK和Tomcat都安装部署到:/export/server 内

cd /

mkdir export

cd export

mkdir server

image-20231121151245852

image-20231121151302727

解压缩JDK安装文件

tar -zxvf jdk-8u321-linux-x64.tar.gz -C /export/server

配置JDK的软链接

image-20231121151429701

配置JAVA_HOME环境变量,以及将$JAVA_HOME/bin文件夹加入PATH环境变量中

vim /etc/profile

export JAVA_HOME=/export/server/jdk
export PATH=$PATH: $JAVA_HOME/bin

image-20231121151605561

生效环境变量

source /etc/profile

删除系统自带的java程序

rm -f /usr/bin/java

软链接我们自己的java

ln -s /export/server/jdk/bin/java /usr/bin/java

执行验证

image-20231121152203013

分发

hadoop2,3先创建文件夹

image-20231121152551441

hadoop分发

cd /export/server/

scp -r jdk1.8.0_321/ hadoop2:`pwd`

scp -r jdk1.8.0_321/ hadoop3:`pwd`

cd /etc

scp -r profile hadoop2:`pwd`

scp -r profile hadoop3:`pwd`
hadoop2,3
source /etc/profile

rm -f /usr/bin/java

ln -s /export/server/jdk/bin/java /usr/bin/java

image-20231121153044737

hadoop

上传和解压

image-20231121153212312

cd /export/server

 tar -zxvf hadoop-3.3.6.tar.gz 

ln -s hadoop-3.3.6 hadoop

image-20231121153407521
