nodered 如何升级https 访问

您可以通过运行以下命令在Node-RED中实现https访问升级：

sudo nano /etc/nginx/sites-available/default

在配置文件中添加以下行，替换YOUR_DOMAIN_HERE和YOUR_EMAIL_HERE以更改为您自己的值：

server {
        listen 80;
        server_name YOUR_DOMAIN_HERE;

        return 301 https://$host$request_uri;
}

server {
        listen 443 ssl;
        server_name YOUR_DOMAIN_HERE;

        ssl_certificate /etc/letsencrypt/live/YOUR_DOMAIN_HERE/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/YOUR_DOMAIN_HERE/privkey.pem;

        location / {
                proxy_pass http://127.0.0.1:1880;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
        }
}

然后，运行以下命令来安装Let's Encrypt SSL证书：

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx
sudo certbot --nginx -d YOUR_DOMAIN_HERE -m YOUR_EMAIL_HERE --redirect --agree-tos --no-eff-email

这将在您的服务器上安装运行Nginx，并自动设置https访问。
