跨账号同区域云服务器搭建hadoop集群

虚拟机下需要

1.关闭防火墙、2.关闭selinux

systemctl status fifirewalld

vi /etc/selinux/config


3.创建目录

mkdir -p /opt/lagou/software

mkdir -p /opt/lagou/servers

4.下载jdk

cd /opt/lagou/software

wget https://download.java.net/openjdk/jdk8u41/ri/openjdk-8u41-b04-linux-x64-14_jan_2020.tar.gz

//wget https://archive.apache.org/dist/spark/spark-2.4.5/spark-2.4.5-bin-without-hadoop-scala-2.12.tgz

5.解压并移动

tar -zxvf openjdk-8u41-b04-linux-x64-14_jan_2020.tar.gz

mv java-se-8u41-ri/ ../servers/jdk1.8.0_231

6.配置环境变量

vim /etc/profile

JAVA_HOME export JAVA_HOME=/opt/lagou/servers/jdk1.8.0_231 export PATH=:PATH:JAVA_HOME/bin

source /etc/profile

7.验证jdk安装

java -version

8.安装rz sudo yum install lrzsz -y

9.上传hadoop安装包

wget https://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.9.2/hadoop-2.9.2.tar.gz

tar -zxvf hadoop-2.9.2.tar.gz -C ../servers/

vim /etc/profile

HADOOP_HOME export HADOOP_HOME=/opt/lagou/servers/hadoop-2.9.2 export PATH=:PATH:HADOOP_HOME/bin export PATH=:PATH:HADOOP_HOME/sbin

source /etc/profile

10.添加java

echo "export JAVA_HOME=/opt/lagou/servers/jdk1.8.0_231" >> /opt/lagou/servers/hadoop-2.9.2/etc/hadoop/yarn-env.sh

echo "export JAVA_HOME=/opt/lagou/servers/jdk1.8.0_231" >> /opt/lagou/servers/hadoop-2.9.2/etc/hadoop/hadoop-env.sh

11.修改主机名称

编辑/etc/cloud/cloud.cfg文件,将preserve_hostname配置项的值由false修改为true,保存并退出

在实例中修改

hostnamectl set-hostname *****

12.生成公钥

cd ~

ssh-keygen -t rsa -P ""

cat id_rsa.pub >> authorized_keys

scp authorized_keys master:/root/.ssh/tmp

cat tmp >> authorized_keys

13.mkdir -p /var/lib/hadoop-hdfs

14.配置core-site.xml
