第 10 章 使用 RHUI 4 命令


Red Hat Update Infrastructure 提供了一个强大的脚本界面,用于管理 RHUI 节点、存储库和客户端配置。

10.1. 使用 RHUI 4 CLI 选项

Red Hat Update Infrastructure 4 的大多数管理任务都是其安装中。安装后,它会自行运行,定期从红帽 CDN 获取更新的软件包,并自动将那些软件包提供给客户端。

名为 Red Hat Update Infrastructure Management Tool 的命令行界面(使用 rhui-manager运行 )有助于安装。此工具提供了每个 RHUI 组件所需的配置元素的交互式提示:RHUA、CDS 和 load-balancer。该工具还提供了用来获取红帽提供的内容证书,以便在连接到 Red Hat CDN 时使用并生成内部云相关证书,以供客户端用于连接到 RHUI。Red Hat Update Infrastructure Management Tool 允许云供应商生成客户端配置捆绑包,以便在客户端 RHEL 实例中安装。此捆绑包允许客户端从 RHUI 安装中获取更新。

Red Hat Update Infrastructure Management Tool 使用互动 shell ; 一些功能也可以在 shell 提示符中运行。Red Hat Update Infrastructure Management Tool 使用七大命令。对于每个命令的 子命令,如果 子命令需要一个或多个选项 -h--help,则提供一个选项列表。
