1.安装依赖包

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

2.设置阿里云镜像源

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

3.更新 yum 缓存

sudo yum makecache

4.安装 docker-ce

sudo yum install docker-ce

5.启动docker

配置开机启动
sudo systemctl enable docker 
启动docker
sudo systemctl start docker

6.配置国内镜像

阿里云提供了镜像源：https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

需要阿里云账号登录后你会获得一个专属的地址。

# 创建配置目录
mkdir -p /etc/docker

# 创建配置文件

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://xxxxxxxxxxxxx.mirror.aliyuncs.com"]
}
EOF


# 重新加载配置文件
sudo  systemctl reload  docker
sudo systemctl daemon-reload

# 重启docker
sudo  systemctl restart docker
