我的服务器的所有 IP 都重定向到我的网站

我有一台服务器，它有一个主 IP（服务器的默认 IP）和两个附加 IP。

问题是我的服务器的所有 IP 都重定向到我的网站。

我只希望主 IP 重定向到 IPv6 和 IPv4 中的我的网站。

这是我的配置：

$ sudo nano /etc/netplan/50-cloud-init.yaml

network:
    version: 2
    ethernets:
        ens3:
            dhcp4: true
            dhcp6: no
            addresses:
                - 2001:41d0:666:1000::a5e/64
                - 164.532.101.48/32
                - 164.532.101.49/32
            gateway6: 2001:41d0:666:1000::1
            routes:
                - to: 2001:41d0:666:1000::a5e/64
                  via: 2001:41d0:666:1000::1
            match:
                macaddress: fa:96:9e:f0:27:b2
            set-name: ens1

答案1

您应该重新启用 Debian 版本的 nginx 附带的默认服务器，并default_server从server主机块中删除您不想实际成为默认服务器的服务器。此后，对您的 IP 地址的请求将仅获得“它有效”页面（您可以稍后根据需要进行更改）。

答案2

看起来 Nginx 正在监听你所有的接口：

了解 nginx‘listen’指令的不同值

如果您要求 Web 服务器仅监听某个特定地址，请按照此处文档中的 listen 指令指定它们：

http://nginx.org/en/docs/http/ngx_http_core_module.html#listen
