配色\n用户有很多配色方案可以选择，默认是 `OpenAI-Partial`。参考了 [OpenAI Developer Forum](https://community.openai.com/)。OpenAI 的配色十分好看，我们想要模仿，即是可以用 console 调出 `:root` 的 `color_definitions.css`，可惜没法完全一样。\n\n[details=\"OpenAI-Partial-Dark Palette\"]\n```json\n\"OpenAI-Partial-Dark\": {\n \"primary\": \"ffffff\",\n \"secondary\": \"262727\",\n \"tertiary\":

我相信透明带来的安全，所以在这里把技术架构通通告诉大家，方便新功能的开发、发现现有的问题，如果你也想建一个这样的网站也可以作为参考。

可以通过功能更新 CHANGE LOG 页面看到，我们在 Discourse 的基础上添加了许多功能。下面将事无巨细地交代：

单一源站：Discourse

在一台安全稳定的服务器上:

pacman -S docker git\nsystemctl enable --now docker\ncd /var/\ngit clone https://github.com/discourse/discourse_docker.git discourse\ncd discourse\n./launcher rebuild app\n

多个反向代理服务器

源站位于高可靠性机器上，但是网络对于中国不是最优的，所以配置反向代理，采用多台优质回国线路、但是配置普通的机器加速：

\n

配色

用户有很多配色方案可以选择，默认是 OpenAI-Partial。参考了 OpenAI Developer Forum。OpenAI 的配色十分好看，我们想要模仿，即是可以用 console 调出 :root 的 color_definitions.css，可惜没法完全一样。

OpenAI-Partial-Dark Palette

\"OpenAI-Partial-Dark\": {\n  \"primary\": \"ffffff\",\n  \"secondary\": \"262727\",\n  \"tertiary\": \"2ec27e\",\n  \"quaternary\": \"b9b4ec\",\n  \"header_background\": \"111111\",\n  \"header_primary\": \"dddddd\",\n  \"highlight\": \"b496ff\",\n  \"danger\": \"f17173\",\n  \"success\": \"09cf09\",\n  \"love\": \"fa6c8d\",\n  \"selected\": \"183d31\",\n  \"hover\": \"2d2e31\"\n}\n

OpenAI-Partial Palette

\"OpenAI-Partial\": {\n  \"primary\": \"202123\",\n  \"secondary\": \"ffffff\",\n  \"tertiary\": \"10a37f\",\n  \"quaternary\": \"715fde\",\n  \"header_background\": \"ffffff\",\n  \"header_primary\": \"333333\",\n  \"highlight\": \"482da8\",\n  \"danger\": \"ef4146\",\n  \"success\": \"009900\",\n  \"love\": \"fa6c8d\",\n  \"selected\": \"e6f3f3\",\n  \"hover\": \"f7f7f8\"\n}\n

在线配置

网页端可以改不少配置选项，比较重要的有：

base font 以及针对 code blocks 使用 Intel One Mono
固定左边栏类别的顺序，调整移动设备上顶栏按钮的顺序和桌面/移动端可见性
调整“提醒注册”的 banner 对已登录用户不可见
中文帖名和内容的长度，用户名长度限制，保留的用户名及 regex
不同 Trust Level 实现的条件、允许的功能和 rate limit (incl. API key)
max image size kb, max attachment size kb, 需要./launcher enter app 改 nginx 的配置
AI 模型选择和服务网址

存在的问题

Discourse docker 容器里面使用 nginx 做服务器，监听到 unix socket，再用宿主机 caddy 反代，存在~~性能损失~~（unix socket 很高效，可以忽略）和不必要的内存占用
nftables 和 docker 冲突，~~没有配置防火墙~~ 已采用云服务商防火墙
