1、使yum的CentOS-Extras配置生效

文件CentOS-Base.repo中enabled的値从0变成1

vim /etc/yum.repos.d/CentOS-Base.repo

[extras]

name=CentOS-$releasever - Extras

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

enabled=1 ★ 値从0变成1

※Docker is included by default in the CentOS-Extras repository

2、执行yum　安装

# yum install docker

3、Docker启动

# systemctl start docker
