Ubuntu 无法在nginx中配置代理\u传递

我想将请求传递给HTTP代理服务器，proxy_pass指令在一个位置内指定

在我的

/etc/nginx/nginx.conf

中，我配置：

server { location ~ ^/api/(.*)$ {

  listen 80;
  listen [::]:80;
  location ~ ^/api/(.*)$ {
    proxy_pass 127.0.0.1:8080;
}
}
}

当我执行这个命令时，

服务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状态nginx.service的输出

将配置文件更改为

server { 
  listen 80;
  listen [::]:80;
  location ~ ^/api/(.*)$ {
    proxy_pass 127.0.0.1:8080;
  }
}

您添加了两次
location~ ^/api/（.*）$
，这是不正确的
 您必须在proxy\u pass指令中使用http://前缀：

proxy_pass http://127.0.0.1:8080;

是否按照输出中的建议运行了
systemctl status nginx.service
？它将为您提供有关该问题的更多详细信息。现在您可以查看状态。谢谢，现在我没有错误。我的Nginx启动了。但我仍然没有在端口80上的UI和端口8080上用Tomcat启动的后端之间建立连接。你对此有什么建议吗？
