本文介绍通过代理的方式，即使身在目标服务区域之外，提供访问LLM的入门方案。

在LLM服务区申请vps搭建代理服务器

在美西申请一台龟壳云服务器(Ubuntu 24.04.4 LTS)

安装代理服务

$sudo apt update && sudo apt upgrade -y
$bash <(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh) install
$xray --version
Xray 26.3.27 (Xray, Penetrates Everything.) d2758a0 (go1.26.1 linux/amd64)

配置

$xray uuid
f1a2b3c4-5d6e-7f8a-9b0c-1d2e3f4a5b6c
$xray x25519
Private key: yLTMMfcsJJ3Fh4t_Pjf777iDhCYx0-PSmksmKBrpRAI
Public key: IGoeCjQm24_wA9M0N3WMVV3ze8NKXb_Yv7CEU_HKMwQ
$openssl rand -hex 8
0123456789abcdef

/usr/local/etc/xray/config.json

重启服务

sudo systemctl restart xray

安全组允许TCP/UDP:443外部访问(Inbound)

配置访问客户端

验证代理服务443端口可以访问

Test-NetConnection 54.168.29.16 -Port 443

安装v2rayN-windows-64-desktop

V7.24.9

创建/增加VLESS订阅

切换代理模式并做检查

• 关掉TUN，只开”PAC mode”

检查是否可以访问GPT

• 打开TUN

检查是否可以访问GPT
