在安装docker时failure: repodata/repomd.xml from mirrors.aliyun.com_dockece_linux_centos_docker-ce.repor

在安装docker时报错

failure: repodata/repomd.xml from mirrors.aliyun.com_dockece_linux_centos_docker-ce.repor: [Errno 256] No more mirrors to try.
http://mirrors.aliyun.com/dockece/linux/centos/docker-ce.repor/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

解决

进入目录

cd /etc/yum.repos.d

执行rm -rf删除所有

rm -rf *

然后

yum update

之后
重新设置yum源

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

yum clean all && yum update && yum makecache

最后
安装docker

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum install docker-ce docker-ce-cli containerd.io

运行查看docker

systemctl start docker

docker version
