yum -y install docker 提示missing signature

参考这里 https://www.8a.hk/news/content/8235.html

卸载旧的docker

sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine

安装依赖

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

切换镜像

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装docker

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

安装Docker

因为docker客户端太老了
systemctl enable docker
systemctl start docker
systemctl status docker
显示activate基本没有问题

docker pull 总是io timeout
