安装步骤:

1、卸载已经安装的Docker

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

2、配置阿里云yum源仓库
1 sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3、查看可以安装的docker版本

1 #yum list docker-ce --showduplicates | sort -r //查看可以安装的版本并倒序排序

4、安装最新版本Docker
注意：安装Docker最新版本，无需加版本号：
1 sudo yum install -y docker-ce

5、设Docker阿里云加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF‘
{
  "registry-mirrors": ["https://xxxxx.mirror.aliyuncs.com"]
}
EOF

6、启动Docker

 sudo systemctl daemon-reload //重新加载服务配置文件

 sudo systemctl enable docker.service && systemctl restart docker.service   //设置开机启动与重启docker服务

7、查看Docker版本
