centos8很坑的就是要更换yum源
/etc/yum.repos.d
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.

都配置好了安装docker 会爆错，明明我的版本是CentOS 系统的内核版本高于 3.10，还报错
解决办法
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
然后
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl start docker
systemctl enable docker
在执行yum install -y docker-ce 中又出现了问题
解决办法
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
然后继续执行就行了
yum install -y docker-ce systemctl start docker systemctl enable docker
