09_docker-ce安装启动：80分钟一口气学完docker+k8s！带你掌握docker+k8s所有核心知识点，全程干货，无废话！
使用docker首要就是获取镜像文件，默认下载是从Docker Hub下载，网速较慢，国内很多云服务商都提供了加速器服务，阿里云加速器，Daocloud加速器，灵雀云加速器。清除防火墙策略，并将getenforce改为Disabled;1、docker必须安装在Centos7平台，内核版本不低于3.10。更新两个epel和CentOS-Base.repo仓库。禁止开机自启防火墙，关闭防火墙服务。2
·
机器环境初始化：
1、防火墙
2、yum源
3、安装基础软件
更新两个epel和CentOS-Base.repo仓库

配置docker加速器
使用docker首要就是获取镜像文件，默认下载是从Docker Hub下载，网速较慢，国内很多云服务商都提供了加速器服务，阿里云加速器，Daocloud加速器，灵雀云加速器。

Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.
