系统环境
CentOs7 (linux)
======================
1、更新系统
# yum -y update# yum -y install iptables-services# systemctl start iptables# systemctl enable iptables# iptables -F # iptables -nl# reboot
2、新建一个docker目录，把rpm传到docker目录下
# mkdir docker # cd docker# yum -y install *
附上rpm包下载地址如下：
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpmhttps://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
3、启动并测试docker
#systemctl start docker#systemctl status docker# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
恭喜，你的docker环境已经搭建成功
如果执行docker run hello-world 之后一直没有结果，可能是网络状态不好，我下面要介绍的内容将改善这个问题。
4、docker 镜像仓库加速配置
# mkdir -p /etc/docker# tee /etc/docker/daemon.json <{ "registry-mirrors": ["https://y5oqqpjx.mirror.aliyuncs.com"]}EOF# systemctl daemon-reload# systemctl restart docker
配置加速完成，再试启动docker run hello-world，运行正常。
