## 待学内容

- MySQL最左匹配原则


## 基于go语言开发轻量级的blog sys展望

我一直有这个想法，暂时还没法动手，不过我有时间总是会把这个flag实现的，简单说说我的想法，首先一定要足够轻量但是又不轻量（很怪但是这就是我的目标），其次应该在后端做很多不影响访问性能的优化，具体可以参考inis的这里的特点：https://inis.cc/#/theme/1 。我的vanblog肯定也会一直保留的，不过保留的地方确实个问题，目前暂时考虑还是薅羊毛Azure和aliyun的服务吧，等这些弄完后都是几年后了，几年后的事情几年后再说。功能暂时想到的有友链检活、使用简约的不同颜色切换带来完全不一样的色彩blog体验、文字修改加上类似GitHub一样的红绿标志。主要都是从别人的blog那边参考过来，所以得多看大佬得blog，其他暂时待定

## 内嵌editor 和 comment 两大服务构建微服务版本的hexo

这个暂时在计划中，目前的想法还是比较多的，可以考虑改qexo的逻辑成为go代码，但是要考虑vercel能不能部署微服务，从理论上来看是可以的，暂时可以考虑通过两种小方式来测试此方案是否可行，比如两个hexo目录在同一个仓库，定义号路由的话能不能做到同时在一个项目里面部署两个网站呢？还有就是我可以写一个简单的go打印监听api的方法来看看是否能做到部署hexo的同时还能响应go api接口的请求，通过这两个方法可以很轻松的知道能不能vercel能够监听好微服务请求，根据我的经验来看应该是可以的，不过需要定义号请求转发规则就是了，实在不行可以参考下其他云服务serverless部署go项目之类的教程，比如有此类云服务商品的项目，比如aliyun，腾讯云等等。本来是想参考下其他云服务的serverless部署方法，没想到不同的云服务对于serveless的使用差距特别大，没办法还是只能自己折腾了，最后可能会魔改成headless模式。

## 安装mix-space部署过程记录

进入宝塔面板—网站，设置后端网站地址这里使用 api.miaoer.xyz

自己喜欢啥主机名就填啥，记得解析

新建完成站点到设置-反向代理-添加反向代理

代理名字这里方便管理就设置为 后端

目标URL: http://127.0.0.1:2333 发送域名: $host

保存后点击 配置文件 将下方配置文件文本复制复制进去，记得全选删掉以前的配置 ，不要去配置文件里面改nginx的配置

为什么使用mx-space？因为他足够有趣～想过一句话，如果你的blog简约充满各种高大上的技术文章，那么等你退休之后你可能甚至不愿意打开你的blog一眼
