第 7 章 使用 Kickstart
很显然,最好是在最初建立系统时修改其配置。对于已经有效使用 kickstart 的客户,最好使用引导程序脚本完成此过程。
完成所有配置工作后,系统仍可能使用
up2date 和 rhn_register RPM 自带的 rhnreg_ks 工具在本地 Red Hat Network 服务器进行注册。本章讨论的是如何正确使用 rhnreg_ks 注册系统。
rhnreg_ks 工具程序使用 激活码(activation keys) 来进行注册、获得权利并将系统订阅到特定的频道。要了解更多关于激活码的信息,请参阅《Red Hat Network Management 参考指南》中的Red Hat Update Agent 和 RHN 网站这两章。
以下这个带有注释的 kickstart 文件是一个如何配置一个系统使用 Red Hat Network 的示例。

# utility for rhn_register. This demonstrates the usage of the
# --activationkey flag, which describes an activation key. For example,
# this activation key could be set up in the Web interface to join this
# system to the "Laptops" group and the local Widgetco "Laptop Software"
# channel. Note that this section applies only to Proxy users, as this
# step is handled by the Satellite bootstrap script.
