使用 nginx 将域名与 Linux VPS 服务器 ip 连接起来

我有一台 VPS Linux（Ubuntu）服务器，我想通过 nginx 将域名与我的服务器 IP 连接起来，但 nginx 不起作用。我已检查以下内容：

$ sudo systemctl reload nginx

nginx.service is not active, cannot reload

$ sudo service nginx start
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

$ systemctl status nginx.service
● nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Sun 2022-05-15 18:53:40 CEST; 11s ago

$ sudo nginx -t
nginx: [emerg] unknown "connection_upgrade" variable
nginx: configuration file /etc/nginx/nginx.conf test failed

关于在我自己的域上运行应用程序，我有一个 nginx 配置文件：

$ sudo cat /etc/nginx/sites-available/shiny

server {

        server_name my_domain.com;

        location / {
                proxy_pass http://localhost:80;
                proxy_redirect / $scheme://$http_host/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection $connection_upgrade;
                proxy_read_timeout 20d;
                proxy_buffering off;
        }

}

如果有人能帮助我解决这个问题我将不胜感激。

只需用这个proxy_set_header Upgrade $http_upgrade;替换/etc/nginx/sites-available/shiny：

proxy_set_header Connection "upgrade";

然后运行nginx -t测试配置文件，如果一切正常的话，输出应该是这样的：

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

然后运行nginx -s reload，这样 nginx 将动态更新配置。

并且不要忘记删除它proxy_redirect / $scheme://$http_host/;并 listen 4444在服务器块末尾添加一个来指定监听端口。
