无法使用公共 IP 地址连接到 Linux Ubuntu Azure VM

无法使用公共 IP 地址连接到 Linux Ubuntu Azure VM。

我已经尝试了一切。

  1. 激活“ufw”并允许端口 80
username@LinuxLR:\~$ sudo ufw status

Status: active

​

To                         Action      From

\--                         ------      ----

80                         ALLOW       Anywhere

443                        ALLOW       Anywhere

Nginx HTTP                 ALLOW       Anywhere

80 (v6)                    ALLOW       Anywhere (v6)

443 (v6)                   ALLOW       Anywhere (v6)

Nginx HTTP (v6)            ALLOW       Anywhere (v6)
  1. 我发现了一些关于强制启用端口 80 上的流量的方法

sudo iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT

  1. 使用本地主机进行测试。“curl localhost”抓取页面上的 html。“curl public ip address”没有给出响应。实际上什么都没有发生。

username@LinuxLR:\~$ curl http://127.0.0.1/


<html>

<head>

<title>Welcome to nginx!</title>

<style>

body {

margin: 0 auto;

}

</style>

</head>

<body>

<p>If you see this page, the nginx web server is successfully installed and

working. Further configuration is required.</p>

<p><em>Thank you for using nginx.</em></p>

4. Similar thing with wget. "wget localhost" grabs the usual nginx html page. "wget public ip address" does:

```username@LinuxLR:\~$ wget "public ip address"

\--2022-10-19 19:40:43--  "public ip address"

Connecting to "public ip address"... failed: Connection timed out.

Retrying.
