**安装：**

1、Docker要求CentOS系统的内核版本高于 3.10 ，通过 **uname -r **命令查看你当前的内核版本是否支持安账docker

2、更新yum包：sudo yum update

3、安装需要的软件包，yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

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

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

5、可以查看所有仓库中所有docker版本，并选择特定版本安装：yum list docker-ce --showduplicates | sort -r

6、安装docker：sudo yum install docker-ce-17.12.0.ce

7、启动、设置开启开机启动

sudo systemctl start docker

sudo systemctl enable docker

8、验证安装是否成功(有client和service两部分表示docker安装启动都成功了)：docker version

9、查看docker启动状态：systemctl status docker（如下图即启动成功）
