1、安装docker并配置镜像加速

1.1 Ubuntu安装docker

  • 安装一步一步的步骤我就不详细介绍了，网上自己搜索吧，我这里就写个简单脚本安装 image.png
[root@jiangmin ~]#bash install_docker_ubuntu.sh
Docker已安装，退出
[root@jiangmin ~]#docker version

  GitCommit:        fec3683

1.2 centos7安装docker

  • 也写个简单脚本安装吧 image.png
[root@centos-7 ~]#bash install_docker_for_centos7.sh
[root@centos-7 ~]#docker version

1.3 centos8安装docker

这次我直接上代码，因为centos8跑docker，生产大概都不会用吧

[root@centos-8 ~]#cat install_docker_for_centos8.sh 
#!/bin/bash

}

	docker version && ${COLOR}"Docker安装成功"${END} || ${COLOR}"Docker安装失败"${END}
}
rpm -q docker &> /dev/null && action "Docker已安装" || install_docker
