AppStream/PowerTools源，ARM上名字形如*module_el8.0.0+*的软件无法直接通过yum安装，需要手动下载到本地建立local repo。

1. 创建本地源目录。

   1 2 3 4 5 6

   mkdir -p /opt/ovirt/centos/8.1.1911/ cd /opt/ovirt/centos/8.1.1911/ mkdir -p AppStream/kickstart/ mkdir -p AppStream/os/ mkdir -p PowerTools/kickstart/ mkdir -p PowerTools/os/

2. 创建CentOS 8.1 AppStream OS本地源。

   1 2 3 4 5 6

   cd /opt/ovirt/centos/8.1.1911/AppStream/os/ wget http://mirrors.huaweicloud.com/centos-vault/8.1.1911/AppStream/aarch64/os/Packages/ cat index.html | grep href | awk -F"\"" '{print $4}' | grep module_el8 | xargs -I {} wget http://mirrors.huaweicloud.com/centos-vault/8.1.1911/AppStream/aarch64/os/Packages/{} createrepo_c . repo2module -s stable -d . modules.yaml modifyrepo_c --mdtype=modules modules.yaml repodata/

3. 创建CentOS 8.1 PowerTools OS本地源。

   1 2 3 4 5 6

   cd /opt/ovirt/centos/8.1.1911/PowerTools/os/ wget http://mirrors.huaweicloud.com/centos-vault/8.1.1911/PowerTools/aarch64/os/Packages/ cat index.html | grep href | awk -F"\"" '{print $4}' | grep module_el8 | xargs -I {} wget http://mirrors.huaweicloud.com/centos-vault/8.1.1911/PowerTools/aarch64/os/Packages/{} createrepo_c . repo2module -s stable -d . modules.yaml modifyrepo_c --mdtype=modules modules.yaml repodata/

4. 新建local repo文件。

   1	touch /etc/yum.repos.d/CentOS-AppStream-PowerTools-local.repo

5. 将以下配置写入“/etc/yum.repos.d/CentOS-AppStream-PowerTools-local.repo”文件。
