【概述】
- 简单docker搭建Ghost
- 复杂docker-compose搭建Ghost+Nginx
核心步骤
解析域名启动docker容器- 访问网页
具体步骤
- 域名：
购买服务器VPS+解析域名 - 环境：创建帐号，并预设权限
- 环境：安装docker和docker-compose
- 环境：
创建docker网络，用于串联ghost和nginx等容器 - 博客：
配置ghost的映射目录和博客配置文件 - 博客：
创建运行ghost容器 - 代理：
配置nginx映射目录和代理配置文件 - 代理：
创建运行nginx容器 - 证书：
创建运行certbot容器，并更新证书 - 部署成果，访问成功
部署过程
购买服务器VPS+解析域名
- Linode注册充值（已弃用，改用oracle的）
官网：www.linode.com
推荐码：注册充值时，填写推荐码，可以获得20美金赠送。
推荐码：acd1469162f9392327ba6850077ea3512a521ec3 - Linode创建多个实例
- ping一番，考察下哪里的服务器快，保留快的那个实例，其它都可以删了
- 部署centos7系统，linode4669841_tokyo » Dashboard » Deploy an Image
- 在域名服务商那，修改dns记录，添加a记录指向你的服务器IP
创建帐号，并预设权限
- 创建ghost专用帐号
# 创建帐号

------------------关闭docker实例-----------------
执行：docker-compose down停掉容器
报错：docker-compose down validating /www/certbot/docker-compose.yml: (root) Additional property certbot is not allowed
解决：这是旧版yml配置写法与新版docker-compose不兼容导致，根据 docker-compose 的标准，所有服务应该放在 services 下。
报错：docker-compose down validating /www/ghost/docker-compose.yml: services.ghost Additional property net is not allowed
解决：新版不支持net属性标签，改为networks，并且值为换行的- net_name
报错：docker-compose down service "ghost" refers to undefined network ghost_net: invalid compose project
解决：如果ghost_net已经存在，则需要定义一下服务节点“networks: ghost_net: external: true”创建docker网络

在certbot里确认，并提示通过后，到宿主机重载
[ghost@instance-20210526-1514 certbot]$ docker exec nginx nginx -s reload部署完成，访问成功
- 博客地址：现在我们访问【ghost.atibm.com】
- IP解析：经过【域名 dns】解析到【服务器】
- 反向代理：由【服务器 nginx服务】做代理处理，访问内部网络【服务器 docker network:ghost_net】
- 博客服务：找到并访问【服务器 ghost服务】+【服务器 certbot服务生成的证书文件】，博客数据存储到【ghost容器映射宿主机目录】下，
- 经过一番折腾，我们实现了代理、程序、数据、证书全部分离，并一起工作，并且后续维护简单，比如升级ghost，备份数据等等。
备份：后续还要编写一键备份脚本，免费实现数据安全
扩展性：当然还可以体验别的网站程序，比如wiki、ss、leanote、trilium等
运维：有了vps挺爽的，可以随便玩，加上docker的易维护，不怕服务器搞坏
服务器：同时也可以在linode再次新增一个实例出来调试，不影响现有网站
linode已经闲置了，感谢支持
