SAP AI Core 接入Cursor

估计这是全网第一篇把SAP AI Core 接入Cursor 的教程。

教程很简单，按照下面项目README，跑一个本地AI Core LLM 代理服务器

https://github.com/pjq/sap-ai-core-llm-proxy

http://127.0.0.1:5000

接着找一台有公网IP的电脑，注册绑定好域名，在Nginx设置好反向代理

比如 https://ai-proxy

然后在Cursor 设置自定义Open AI URL

https://ai-proxy/v1

这个代理服务器是手工搓的，目前支持gpt-4,gpt-4o, Claude 3.5 sonnet 统一了OpenAI API协议，所以可以用到任何兼容OpenAI API 的客户端。

至此，Token自由。

群晖双网口OpenWRT软路由设置

家里的黑群之前用OpenWRT做软路由的时候买过一个网卡，最近把黑群升级到了最新版本，软路由虽然一直没用，但还是把它设置起来以备不时之需。

所以现在有两个网卡

LAN 1(Default)
LAN 2(新加的)

在Virtual Machine Manger里增加两个网卡

eth0 -LAN 2(新加的)
eth1 -LAN 1(Default)

在Virtual Machine-OpenWrt这个虚拟机上加入上面新增的两个网卡，这样就等于在 OpenWrt里插入了两个网卡eth0, eth1

接下来在OpenWRT里面分别设置eth0(LAN2,新加的)作为局域网， eth1(LAN1,Default)作为外网连接，设置网关为家里路由器的ip, 内部局域网段为192.168.2.xxx

eth0-lan(内网)
eth1-wan(外网)

cat /etc/config/network
/etc/init.d/network restart

Cloudflare转发公网IP非443端口

上海电信公网IP开通后，一些常用的端口如80和443不能使用。因此，必须使用其他端口，例如将443端口改为8443端口。访问时还需要在URL中加入特定的端口号：https://host:8443。

昨天搜了一下，原来Cloudflare支持转发非443端口，你需要做的就两步

DNS enable proxy
Rules-Origin Rules-Custom Filter Expression, 在这里添加一些转换规则-Then rewrite to “8443”

这样就设置好了，通过访问https://host， Cloudflare就会自动转到了源地址https://host:8443

群晖启用xiaogpt

使用Docker来开启xiaogpt, 当前Docker官文Docker源被墙了，所以可以先找一个国内的镜像，比如

https://dockerproxy.cn

docker pull dockerproxy.cn/yihong0618/xiaogpt

准备好config.yaml文件，然后命令行启动

docker run -v /volume2/hdd_4T/xiaogpt/config:/config yihong0618/xiaogpt --config=/config/myconfig_livingroom.yaml

In the syno storage management, it can’t show the disk information.
