1、首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
2、进入yum源配置文件所在的文件夹
cd /etc/yum.repos.d/
3、下载163的yum源配置文件(CentOS7)
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
清华大学镜像源地址:https://mirrors.tuna.tsinghua.edu.cn/
4、清理缓存
yum clean all
5、测试下载安装
yum install gcc
6、安装docker
yum install docker
7、启动
systemctl start docker
启动报错

根据提示查看一下详情,执行:journalctl -xe

错误原因:error initializing graphdriver: driver not supported
解决办法:在 /etc/docker 目录下创建daemon.json文件,并且加入以下配置
touch daemon.json
vi daemon.json
{
"storage-driver": "overlay2",
"storage-opts": [
"overlay2.override_kernel_check=true"
]
}
再次启动
systemctl start docker
问题解决
