4.3. 自定义默认配置

您可以创建您自己的配置文件，并使用它来自定义安装程序的配置。

4.3.1. 配置默认配置文件
复制链接

您可以以 .ini 文件格式编写 Anaconda 配置文件。Anaconda 配置文件由section、options 和 comments 组成。每个 section 都由一个 [section] 标头定义，注释以 # 字符开头，键用来定义 options 。生成的配置文件使用 configparser 配置文件解析器进行处理。

默认配置文件位于 /etc/anaconda/anaconda.conf 中，包含记录的部分和支持的选项。该文件提供了安装程序的完整默认配置。您可以修改 /etc/anaconda/product.d/ 中的产品配置文件，以及 /etc/anaconda/conf.d/ 中的自定义配置文件。

以下配置文件描述了 RHEL 9 的默认配置：

4.3.2. 配置产品配置文件
复制链接

产品配置文件有一个或者两个额外的部分来识别这个产品。[Product] 部分指定产品的产品名称。[Base Product] 部分指定基础产品的产品名称（如果有的话）。例如：Red Hat Enterprise Linux 是 Red Hat Virtualization 的基本产品。

安装程序在加载指定产品的配置文件之前加载基础产品的配置文件。例如：它会首先载入 Red Hat Enterprise Linux 配置，然后载入 Red Hat Virtualization 的配置。

请参阅 Red Hat Enterprise Linux 的产品配置文件示例： 

# Anaconda configuration file for Red Hat Enterprise Linux.

[Product]
product_name = Red Hat Enterprise Linux

[Installation System]

# Show a warning if SMT is enabled.
can_detect_enabled_smt = True

[Network]
default_on_boot = DEFAULT_ROUTE_DEVICE

请参阅 Red Hat Virtualization 产品配置文件示例： 

# Anaconda configuration file for Red Hat Virtualization.

[Product]
product_name = Red Hat Virtualization (RHVH)

[Base Product]
product_name = Red Hat Enterprise Linux

[Storage]
default_scheme = LVM_THINP
default_partitioning =
    /              (min 6 GiB)
    /home          (size 1 GiB)
    /tmp           (size 1 GiB)
    /var           (size 15 GiB)
    /var/crash     (size 10 GiB)
    /var/log       (size 8 GiB)
    /var/log/audit (size 2 GiB)

要为您的产品自定义安装程序配置，您必须创建一个产品配置文件。创建名为 my-distribution.conf 的新文件，其内容与上例类似。将 [Product] 部分中的 product_name 更改为产品的名称，如 My Distribution。产品名称应当与 .buildstamp 文件中使用的名称相同。

创建自定义配置文件后，请按照创建 product.img 文件 部分的步骤来创建包含自定义的新 product.img 文件，以及 创建自定义引导镜像以使用包含您的更改创建新的可引导 ISO 文件。

4.3.3. 配置自定义配置文件
复制链接

要自定义与产品名称无关的安装程序配置，您必须创建一个自定义配置文件。要做到这一点，创建一个名为 100-my-configuration.conf 的新文件，其内容类似于 配置默认配置文件中的示例，省略 [Product] 和 [Base Product] 部分。

创建自定义配置文件后，请按照创建 product.img 文件 部分的步骤来创建包含自定义的新 product.img 文件，以及 创建自定义引导镜像以使用包含您的更改创建新的可引导 ISO 文件。
