CDH5.16.1扩容步骤

1 本文博客只是介绍简单的步骤，其他详细的步骤参考之前本人的博客

 1 hostname

        hostnamectl set-hostname

  2 /etc/hosts配置

       所有机器都要同步hostname的配置

  3 ssh免密登录 或者 同步密码登录

        一定所有的机器都需要，因为有高可用 

  4 jdk配置

 

 

 

5 httpd安装

    rpm -qa|grep httpd

 

 yum install -y httpd

 

systemctl list-unit-files | grep httpd

 

 systemctl enable httpd.service

 

systemctl start httpd

 

 

 

6 cp 下载CDH-manager的文件

 

scp * root@hadoop004:/var/www/html/parcels

scp -r cm root@hadoop004:/var/www/html

 

7 cp mysql驱动

mkdir /usr/share/java

scp /usr/share/java/mysql-connector-java.jar hadoop004:/usr/share/java

 

 

8 编辑yum源

  vi /etc/yum.repos.d/cloudera-manager.repo

 

[cloudera-manager]

name = Cloudera Manager, Version 5.16.1

baseurl =http://hadoop001/cm/5/

gpgcheck = 1

 

 

9 提前安装 

    

yum provides '*/applydeltarpm'

    yum install deltarpm

 

yum install /var/www/html/cm/5.16.1/RPMS/x86_64/cloudera-manager-daemons-5.16.1-1.cm5161.p0.1.el7.x86_64.rpm

 

10 更换阿里云的yum源提高安装速度

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

yum clean all 

yum makecache

 

 

10 开始界面安装

选择的私钥方式，是所有主机接受相同私钥  

id_rsa 而不是公钥

 

待定问题，为啥会等待激活
