CentOS安装docker报错解决方法

报错一

Cannot find a valid baseurl for repo: base/7/x86_64

报错二

Error: Package: containerd.io-1.6.33-3.1.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2:2.74
Error: Package: docker-ce-rootless-extras-26.1.4-1.el7.x86_64 (docker-ce-stable)
Requires: slirp4netns >= 0.4
Error: Package: 3:docker-ce-26.1.4-1.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2:2.74
Error: Package: docker-ce-rootless-extras-26.1.4-1.el7.x86_64 (docker-ce-stable)

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

解决方法：上面两个错误通用

sudo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

sudo yum clean all
sudo yum makecache

搞定！！！
