自动安装(后继随机主机名+ netwrok配置)

Question

我试图配置这个网络的工作，但当我登录到操作系统，它不是。第二，如何配置随机主机名？

(谢谢:)

这还不够信息。

如何配置随机主机名？

这有很多种方法。这些是一些部分user-data吐露，展示了一些解决方案。

下面是一个early-commands解决方案，它将更新安装程序本身使用的配置。这样做的好处是主机将使用随机名称安装，以后不需要被另一个进程更改。

#cloud-config
autoinstall:
  identity:
    hostname: REPLACEHOSTNAME
    password: REDACTED
    realname: myuser
    username: myuser
  early-commands:
    - sed -i -e "s/REPLACEHOSTNAME/$(openssl rand -hex 3)/" /autoinstall.yaml

下面是一个cloud-init解决方案，它将cloud-init配置为设置主机名。好处是cloud-init还可以设置fqdn和更新像/etc/hosts这样的文件。

#cloud-config
autoinstall:
  identity:
    hostname: my-hostname
    password: REDACTED
    realname: myuser
    username: myuser
  late-commands:
    - |
      cat < /target/etc/cloud/cloud.cfg.d/80_my.cfg
      hostname: $(openssl rand -hex 3)
      manage_etc_hosts: true
      preserve_hostname: false
      EOF

以下是在已安装的系统上更改/etc/hostname的简单解决方案。

#cloud-config
autoinstall:
  identity:
    hostname: my-hostname
    password: REDACTED
    realname: myuser
    username: myuser
  late-commands:
    - echo $(openssl rand -hex 3) > /target/etc/hostname

笔记

我使用Ubuntu22.04 (subiquity 22.04.2)进行测试。
