首先要了解下 Linux 中的 tty 的概念,具体可以看下面这个解释。简单来说(可能不严谨),你可以类比 macOS 或者 Windows 下的虚拟桌面。

那么启动安装镜像,进入安装界面,就像这样

默认应该是 tty1可以尝试发送 Ctrl+Alt+F1看看有没有反应没有的话说明当前就是 tty1。

要登录公司网络,需要使用 curl 命令发送请求,所以切换到另一个 tty 以输入命令。这边发送 Ctrl+Alt+F2 组合键以切换到 tty2
然后输入命令登录网络即可。我这边用的是深信服的网络登录窗,如何写出这个命令的可以参考这篇文章获取思路。[使用 cli 登陆公司上网验证系统](https://blog.mitsea.com/ddfb7e62396b40c59f74432c862dea69)

最后,回到 tty1 正常安装系统即可。
