本文方法已失效，因为ChatGPT接口API更新，@yuezk不再更新项目。新项目地址https://github.com/mckaywrigley/chatbot-ui
同时ChatGPT官网似乎已经不再屏蔽特定地区的IP地址，所以本文也不再更新。
近来智能AI-chatGPT的热度可谓是引爆互联网，因为前段时间一直在写一个小程序，所有没能在第一时间体验chatGPT，就在上周，算是历经千难万险，终于是在体验上了，效果十分炸裂！码代码算是我的业余爱好，相比我花了三天设计实现的一个简单的共享数据容器，chatGPT只花了1秒，几十行代码就已经浮现在眼前。不得不佩服，当即我就喜欢上了这个东西。简直就是神器，我觉得它是一个划时代的AI，IronMan的贾维斯可能真的会在未来十几年出现。
但是在国内因为种种不肯抗力的因素，直接访问chatGPT官网似乎是一件不太现实的事情，事实也确实如此，首先chatGPT就已经屏蔽了来自中国的IP地址，即使设置代理也会出现Access denied Error reference number: 1020之类的报错。
我尝试了多个代理节点，基本上都是Access denied，后来查询google才知道，原来这个错误是因为CDN节点的问题，只有使用cloudflare公司的CDN节点才能正常访问chatGPT，一番操作下来，又是用美国手机卡接收短信，又是使用google账号登录，最后都是报unsupported_country这个错。好事多磨没办法。一筹莫展之际还是想起了刚开始体验站点fastgpt.app，干脆自己搭建一个镜像站，调用OpenAI的API接口来使用chatGPT吧。Github项目地址chatgpt-mirror。感谢@yuezk
自己搭建一个镜像站需要准备的东西有：
| 一台国外vps | OS：Centos8.2 需要 Node.js 18.x 环境 |
| 一个OpenAI的Key | 用来调用API |
| 一条可靠的访问链路 | 八仙过海 各显神通 |
首先在CentOS8上配置Node.js 18.x的环境，这里需要安装Node.js环境和一个pnpm模块。
[root@localhost ~]#yum install -y epel-release
//安装epel源
[root@localhost ~]# curl -fsSL https://rpm.nodesource.com/setup_18.x | sudo bash -
//安装Node.js18源
## Installing the NodeSource Node.js 18.x repo...
## Inspecting system...
+ rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release || rpm -q --whatprovides fedora-release
+ uname -m
## Confirming "el8-x86_64" is supported...
+ curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_18.x/el/8/x86_64/nodesource-release-el8-1.noarch.rpm'
## As yum will try to install Node.js from the AppStream repository
instead of the NodeSource repository, the AppStream's version of Node.js has to be disabled.
## Run `sudo yum module enable -y nodejs` to reactivate the AppStream's Node.js repository.
+ yum module disable -y nodejs

...接下来需要申请一个OpenAI的key，每个账号会送一个5刀的体验key，大概可以调用1000次接口。这里需要提一下，注册账号确实是需要用非国内的手机接收一个验证码，我这里使用的是这个平台sms-activate.org，反正方法有很多，只要能注册上并且拿到key就行，这里贴一个网易的教程。网上有很多类似的教程。
接下来就是安装和配置项目了，还是很简单的，这里再次感谢@yuezk。

再此之前，我从来没有接触过Node.js，之所以能部署成功，也有chatGPT的帮助，我尝试让它指导我安装这个环境，经过几次尝试以后，我发现如果提的问题描述的够清晰，它还是能给到你很大帮助的。就在我写完这篇文章，我发现chatGPT已经迭代到4.0了，嗨，接着折腾呗~
