无法在 EC2 上打开 8080 端口

我使用 AWS Ubuntu 实例并尝试打开端口 8080。这是我的“安全组”设置：

ec2 映像

我已将端口 8080 添加到 iptables：

sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http-alt

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

防火墙已禁用：

sudo ufw status verbose
Status: inactive

nmap：

nmap localhost

Starting Nmap 7.60 ( https://nmap.org ) at 2020-05-04 20:27 UTC

但是当我使用服务器IP时端口似乎仍然被关闭：

nmap ec2-18-184-30-11.eu-central-1.compute.amazonaws.com

Starting Nmap 7.60 ( https://nmap.org ) at 2020-05-04 20:29 UTC

我应该怎么做才能打开8080端口？

答案1

根据 netstat 输出：

netstat -anltp | grep "LISTEN" 
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      2446/node           
tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN      -                   
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -                   
tcp6       0      0 :::22                   :::*                    LISTEN      -

该服务将仅响应来自本地主机 (127.0.0.1) 的请求。将其更改为主机上可从调用者网络访问的地址（或 0.0.0.0 用于公共访问）将使该服务可访问。此更改通常在服务配置文档或界面中进行。
