### --- docker安装的三种方式（install for linux）：

~~~     script：脚本的方式；
~~~     yum：yum方式安装；
~~~     rpm：rpm包安装(推荐使用)

二、docker部署

### --- 方式一：script install

[root@localhost ~]# yum update
[root@localhost ~]# curl -sSL https://get.docker.com/ | sh
[root@localhost ~]# systemctl start docker
[root@localhost ~]# systemctl enable docker
[root@localhost ~]# docker run hello-world

### --- 方式二：yum install

[root@localhost ~]# yum update
[root@localhost ~]# cat >/etc/yum.repos.d/docker.repo <<-EOF
[dockerrepo]
name=Docker Repository
baseurl=https:///repo/main/centos/7
enabled=1
gpgcheck=1
gpgkey=https:///gpg EOF
[root@localhost ~]# yum install docker

### --- 方式三：rpm install 

https://download.docker.com/linux/centos/7/x86_64/stable/Packages

---

三、通过rpm安装docker服务

### --- rpm包下载：

~~~     # 地址：https://download.docker.com/linux/centos/7/x86_64/stable/Packages
~~~     # 下载：docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
~~~     # docker-selinux：docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm

### --- 环境检查：

[root@localhost ~]# getenforce
Disabled
[root@localhost ~]# systemctl status firewalld.service 
[root@localhost ~]# yum install -y iptables-services
[root@localhost ~]# systemctl start  iptables.service 
[root@localhost ~]# systemctl enable iptables.service 
[root@localhost ~]# iptables -F                         // 清空防火墙默认规则
[root@localhost ~]# service iptables save               // 保存防火墙规则
iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]
[root@localhost ~]# yum update                          // 更新软件包

[root@localhost docker]# ls
docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm

### --- 安装docker rpm包和selinux包

[root@localhost docker]# yum install -y *
