ubuntu - 无法在 nginx 中配置 proxy_pass

Question

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

在我的/etc/nginx/nginx.conf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 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 的输出

您必须在 proxy_pass 指令中使用 http://前缀:

proxy_pass http://127.0.0.1:8080;
