**docker安装要求**

centOs内核版本需要大于3.10

查看方式：**uname -r**

如果未达到要求，自行百度升级内核。

### 安装前骤 ###

如果安装过docker，现在先卸载干净

>     yum remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine
>     
>     rm -rf /etc/systemd/system/docker.service.d
>     
>     rm -rf /var/lib/docker
>     
>     rm -rf /var/run/docker

## centOs6/7在线安装 ##

**一键安装**

yum update -y && yum install -y yum-utils device-mapper-persistent-data lvm2 && yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo && yum install -y docker-ce && systemctl start docker && systemctl enable docker && docker version

1.更新yum源

yum update -y

2.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

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

3.设置yum源

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

4.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

5.安装docker

yum install -y docker-ce

6.启动并加入开机启动

systemctl start docker

systemctl enable docker

7.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
