我有一个 DigitalOcean 液滴，我试图在其中托管多个服务器。准确地说，我有以下设置： 1. 我的个人站点（使用serve
托管的 React 前端）位于 localhost:5000 2. 我的 Jekyll 博客使用Bundler托管（命令：） ，位于 localhost:4000/blog/ 3. 一个 nodejs 项目在 localhost:3031使用pm2托管
bundle exec jeykll serve

当我使用上面带有 localhost 的 URL 从服务器测试它们中的每一个时curl，我得到了正确的响应。

我有一个用 namecheap 注册的域，比如abcd.me，用 cloudflare 来管理我的 DNS 设置。按照他们的说明，我更新了我在 namecheap 上的设置以使用 Cloudflare 的名称服务器。

目前对我有用的是：
- 我可以在https://abcd.me
访问我的个人网站 - 我可以在 http://{droplet-ip}:3031 访问我的 nodejs 项目

我无法实现的目标： - 在https://blog.abcd.me
访问我的博客

目前，访问https://blog.abcd.me会再次返回我的个人站点，只是 URL 以“blog.”为前缀。我的 nginx 配置如下所示：

server {

    listen 3030 default_server;
    listen [::]:3030 default_server;

    server_name {server-ip};

    index index.html index.htm index.nginx-debian.html;

        location / {
                proxy_pass http://localhost:3031;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
        }

}

server {
    listen 80;
    listen [::]:80;

        root /var/www/html;
        index index.html index.htm index.nginx-debian.html;

        server_name blog.abcd.me www.blog.abcd.me;

        location / {
                proxy_pass http://localhost:4000/blog/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
        }
}

server {
    listen 80;
    listen [::]:80;

    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot




}

我无法弄清楚我哪里出错了。有人可以帮助我吗？
