Docker笔记

1.快速入门

要想让 Docker 帮我们安装和部署软件，肯定要保证你的机器上有 Docker. 由于大家的操作系统各不相同，安装方式也不同。为了便于大家学习，我们统一在 CentOS 的虚拟机中安装 Docker，统一学习环境。

1.1.部署 MySQL

首先，我们利用 Docker 来安装一个 MySQL 软件，大家可以对比一下之前传统的安装方式，看看哪个效率更高一些。

如果是利用传统方式部署 MySQL，大概的步骤有：

  • 搜索并下载 MySQL 安装包
  • 上传至 Linux 环境
  • 编译和配置环境
  • 安装

免费申请SSL证书

Certbot 简介

Github 地址：https://github.com/certbot/certbot 本质上来说，certbot 就是一个 ACME client，这也是 Let’s Encrypt 官网推荐的签发证书的方式，适用于对自己的 domain 具有 shell 访问能力的情况，使用所谓的 ACME 协议来自动化的签发证书，很大程度上简化了证书签发的步骤
