cobbler自动化安装centos8

centos8 已经发布了GA版本，迫不及待的想尝鲜了，然后现实总是那么残酷，一直安装失败，具体安装步骤如下：

假设cobbler已配置完成。

1、下载centos8 iso镜像

wget http://mirrors.aliyun.com/centos/8.0.1905/isos/x86_64/CentOS-8-x86_64-1905-dvd1.iso

2、挂载

$ mount -o loop CentOS-8-x86_64-1905-dvd1.iso /mnt/
$ cd /mnt/
$ cp -r * /iso/centos8.0/
$ cd /iso/centos8.0/
　　AppStream  BaseOS  EFI  images  isolinux  media.repo  TRANS.TBL

3、配置kickstart文件

$ cat /var/lib/cobbler/kickstarts/centos8.0.ks

# System authorization information

auth --enableshadow --passalgo=sha512

# System bootloader configuration

bootloader --location=mbr --boot-drive=sda

part swap --fstype="swap" --ondisk=sda --size=2048
part / --fstype="xfs" --ondisk=sda --size=1 --grow
part biosboot --fstype="BIOS Boot" --ondisk=sda --size=2


%pre

$SNIPPET('log_ks_pre')

$SNIPPET('kickstart_start')

$SNIPPET('pre_install_network_config')

# Enable installation monitoring

$SNIPPET('pre_anamon')

%end

%packages

@^minimal-environment
@standard

%end

4、cobbler 导入

$ cobbler import --name=centos8.0 --path=/iso/centos8.0 --kickstart=/var/lib/cobbler/kickstarts/centos8.0.ks --arch=x86_64

发现报错，报错如下：

No signature matched

$ cobbler import --name=centos8.0 --path=/iso/centos8.0 --kickstart=/var/lib/cobbler/kickstarts/centos8.0.ks
task started: 2019-10-16_074659_import
task started (id=Media import, time=Wed Oct 16 07:46:59 2019)
No signature matched in /var/www/cobbler/ks_mirror/centos8.0
!!! TASK FAILED !!!

解决：

$ cobbler signature update
task started: 2019-10-16_074829_sigupdate
task started (id=Updating Signatures, time=Wed Oct 16 07:48:29 2019)
Successfully got file from https://cobbler.github.io/signatures/2.8.x/latest.json
*** TASK COMPLETE ***

5、装机

然后装机过程中报错了，截图未报错，报错信息是：报错的界面是配置"Installation Source"，报错为:"Error setting up base repository"，反复测试依然有问题，不知道怎么设置，没办法，只能从iso那块下手了，检查iso文件内容。

6、iso配置

iso中有AppStream和BaseOS两个目录，目录中都有Packages目录和repodata目录，将BaseOS中的 BaseOS/repodata/586a8e96ad3b73414e5c6ae94a5e4f128a087fcb0ca9837674573a8d6cac4a9c-comps-BaseOS.x86_64.xml 拷贝到 BaseOS 同级目录下，并将 AppStream/Packages 下的auth*包文件全部拷贝到BaseOS/Packages 下，然后使用 createrepo -g 586a8e96ad3b73414e5c6ae94a5e4f128a087fcb0ca9837674573a8d6cac4a9c-comps-BaseOS.x86_64.xml . 创建repodata目录。

$ cd /iso/centos8.0/
$ ls
    AppStream  BaseOS  EFI  images  isolinux  media.repo  TRANS.TBL
$ cp AppStream/Packages/auth* BaseOS/Packages/
$ cp BaseOS/repodata/586a8e96ad3b73414e5c6ae94a5e4f128a087fcb0ca9837674573a8d6cac4a9c-comps-BaseOS.x86_64.xml ./

$ ls
    586a8e96ad3b73414e5c6ae94a5e4f128a087fcb0ca9837674573a8d6cac4a9c-comps-BaseOS.x86_64.xml  AppStream  BaseOS  EFI  images  isolinux  media.repo  TRANS.TBL

$ createrepo -g 586a8e96ad3b73414e5c6ae94a5e4f128a087fcb0ca9837674573a8d6cac4a9c-comps-BaseOS.x86_64.xml .

$ rm -rf AppStream/repodata BaseOS/repodata

重新使用cobbler import，再使用最小化安装。

当然我配置的可能哪里出了问题，导致出现了"Error setting up base repository"报错，如果哪位大神解决了这个问题，欢迎评论区告知一声。
