cobbler最小化安装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
1 | wget http: //mirrors .aliyun.com /centos/8 .0.1905 /isos/x86_64/CentOS-8-x86_64-1905-dvd1 .iso |
2、挂载
1 2 3 4 | $ 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 | $ cat /var/lib/cobbler/kickstarts/centos8 .0.ks #version=RHEL8 # System authorization information auth --enableshadow --passalgo=sha512 # System bootloader configuration bootloader --location=mbr --boot-drive=sda # Partition clearing information clearpart --all --initlabel # Use text mode install #text graphical # Firewall configuration firewall --disabled # Run the Setup Agent on first boot firstboot --disable ignoredisk --only-use=sda # System keyboard keyboard --vckeymap=us --xlayouts= 'us' # System language lang en_US.UTF-8 # Use network installation url --url=$tree # If any cobbler repo definitions were referenced in the kickstart profile, include them here. $yum_repo_stanza # Network information $SNIPPET( 'network_config' ) # Reboot after installation reboot #Root password rootpw --iscrypted $default_password_crypted # SELinux configuration selinux --disabled # Do not configure the X Window System skipx # System timezone timezone --utc Asia /Shanghai # Install OS instead of upgrade install # Clear the Master Boot Record zerombr # Allow anaconda to partition the system as needed #autopart part /boot --fstype= "xfs" --ondisk=sda --size=500 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
1 | $ 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
1 2 3 4 5 | $ 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:
1 2 3 4 5 | $ 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。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | $ 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 .

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。
