yum 即可
安装dockeryum 即可
下载镜像git clone https://github.com/kiwenlau/hadoop-cluster-docker获取配置文件 必备环节！
git clone https://github.com/kiwenlau/hadoop-cluster-docker修改配置文件
在-p 8088:8088 下添加一行
-p 9000:9000
cd hadoop-cluster-docker/ ./start-container.sh
这时候会话自动变成了hadoop-master权限
进入容器终端systemctl start docker 看情况是否使用
···
sudo docker attach hadoop-master
···
这里要回车下 不然显示空白，像是卡主一样
默认速度较慢，可修改国内源。
本地建gedit sources.list
内容如下：
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse复制到容器-注意本地路径和使用的终端左边是本地，右边是docker
sudo cp /etc/apt/sources.list /etc/apt/sources.list.copy生效
sudo apt-get install vim安装
sudo apt-get install vim
三分钟左右
启动回到根目录 ~
./start-hadoop.sh
一堆warning出来，不用管。
