给指定端口的网页应用绑定域名并强制SSL（申请证书+nginx配置）

给指定端口的网页应用绑定域名并强制SSL（申请证书+nginx配置）

背景

刚刚注册了一个新的chatgpt账号，有5美金余额，又可以用API了，在甲骨文云的Ubuntu22服务器上使用docker部署了一下，之前也写过一篇相关的文章centos7使用docker部署chatgpt - xinhaojin’s blog，默认部署在3002端口，只能使用http访问。

使用的是Chanzhaoyu/chatgpt-web: 用 Express 和 Vue3 搭建的 ChatGPT 演示网页 (github.com)这个项目，可以使用railway一键部署，绑定域名、使用HTTPS都很方便，但是不清楚railway使用会不会超过免费额度，还是决定用自己的服务器小小折腾一下，因为经常搞这套流程，所以还是记录一下。

解析域名到服务器

给域名添加A记录绑定服务器公网IP

申请SSL证书

1
2
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d chat.xinhaojin.top

输出：证书申请成功，但没法自动安装，因为没有在nginx配置中找到域名相关配置

Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/chat.xinhaojin.top/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/chat.xinhaojin.top/privkey.pem
This certificate expires on 2023-10-02.
These files will be updated when the certificate renews.
Certbot has set up a scheduled task to automatically renew this certificate in the background.

Deploying certificate
Could not install certificate

NEXT STEPS:
- The certificate was saved, but could not be installed (installer: nginx). After fixing the error shown below, try installing it again by running:
  certbot install --cert-name chat.xinhaojin.top

Could not automatically find a matching server block for chat.xinhaojin.top. Set the `server_name` directive to use the Nginx installer.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

1.重定向80端口的HTTP请求到443端口HTTPS

server {
    listen       80;
    server_name  chat.xinhaojin.top; 
    return 301 https://$host$request_uri;
}

2.配置443端口使用SSL证书，配置SSL参数
