Bootstrap i686

默认情况下，Koji 不会将软件包构建为多架构，它期望一个 i686 存储库/构建根，因为这是 **mock** 所期望的。看起来它需要一个 32 位引导程序来启动。但是，Enterprise Linux 8 **没有** 32 位存储库。为了解决这个问题，必须使用至少 Fedora 28（以及在某些情况下使用 Fedora 29）来引导软件包。

设置¶

安装 Mock 和配置¶

安装 mock...

% yum install epel-release
% yum install mock createrepo_c httpd -y
% useradd rpmbuild
% usermod -aG mock rpmbuild

添加正确的 mock 配置...

% cat >> /etc/mock/rocky-8-i686.cfg << "EOF"

# with koji's mock settings

设置递归存储库¶

因此，我们可以创建一个空存储库，以便 mock/dnf 可以正常使用它。但是，这并不能解决所有问题。我们首先需要几个 RPM。我们可以拉取 centos 目前拥有的 noarch 软件包来开始。

% mkdir -p /var/www/html/src/{reqs,logs,mirror,hidden}

# Pull required RPM's
% wget http://mirror.centos.org/centos/8.3.2011/AppStream/x86_64/os/Packages/redhat-rpm-config-123-1.el8.noarch.rpm

# Generate repo data
% createrepo /var/www/html/src/reqs

拉取所需的隐藏依赖项¶

我们仍然需要一些隐藏的依赖项。并且其中许多可以在上述设置完成后毫无问题地构建。下面列出了一个列表，可以在我们的临时 copr 上找到。您应该下载源 RPM 并构建它们。

您不会在 copr 中找到 rocky-logos 或 rocky-release。但是您可以在我们的 koji 中找到它们。强烈建议从 koji 下载并构建它们。

可选：从存储库中拉取所有源代码¶

您可能需要从存储库中拉取所有源代码。我使用 httrack 来完成此操作。请注意，此链接可能会失效，您可能需要自己构建它。

另一件事是，在下载完源代码后，我删除了所有旧内容并将所有模块软件包移到了其他位置。

% cd /var/www/html/src/mirror
# -sN 0 helps ignore robots
% httrack https://vault.centos.org/8.3.2011/BaseOS/Source/SPackages/ -sN 0

# Now we need to move some things
% mv vault.centos.org/8.3.2011/BaseOS/Source/SPackages/ BaseOS

% mv vault.centos.org/8.3.2011/PowerTools/Source/SPackages/ PowerTools
% rm -rf vault.centos.org index.html

# I don't want to build modules. I'm doing that in koji, so instead, I'm moving them away.
% mkdir modules
% find . -type f -regextype sed -regex '.*module.*\.rpm' -exec mv {} modules/ \;

# Now I need to remove all the old stuff
# You can use repomanage on directories that are not actual repos and it will operate properly.
% for x in AppStream BaseOS HighAvailability PowerTools ; do rm $(repomanage --keep=1 ${x}) ; done

实际构建¶

我有一个有点 hacky 的脚本可以帮我处理这个问题。您可以一次为它提供一个。

# ~/bin/build-a-rpm
#!/bin/bash
PACKAGE=$1
LOGDIR=/var/www/html/src/logs/${NAME//.src.rpm/}
MOCKDIR=/var/lib/mock/rocky-8-i686
mock -r rocky-8-i386 $1

if [ $? -eq 0 ]; then
  rm ${MOCKDIR}/result/*.src.rpm
  cp ${MOCKDIR}/result/*.rpm /var/www/html/src/reqs
  createrepo /var/www/html/src/reqs
  echo $1 >> /tmp/DONE
else
  mkdir ${LOGDIR}
  cp ${MOCKDIR}/result/*.log ${LOGDIR}
  echo $1 >> /tmp/FAIL
fi
