yum list

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

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

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

二.换源

1.通过 vi/vim 进入<font style="color:rgb(25, 27, 31);background-color:rgb(248, 248, 250);">/etc/docker/daemon.json</font>,如果没有这个文件,需要在<font style="color:rgb(25, 27, 31);background-color:rgb(248, 248, 250);">/etc/docker</font>目录下手动进行创建这个目录,然后写入一下的内容. 
  1. {
  2.     "registry-mirrors":[
  3.         "https://9cpn8tt6.mirror.aliyuncs.com",
  4.         "https://registry.docker-cn.com"
  5.     ]
  6. }
  1. # 重新加载 systemd 的配置
  2. sudo systemctl daemon-reload
  4. # 重启 Docker 服务
  5. sudo systemctl restart docker
