cobbler3使用总结

按照如下步骤进行安装配置，实现PXE+BIOS安装Centos和Ubuntu，UEFI+iPXE安装Windows2019

若想实现UEFI+iPXE安装Centos和Ubuntu，可以参考附录《更全的ipxe/default.ipxe》配置default.ipxe即可

rocky91安装配置cobbler3.3.3

准备工作

rocky91的IP地址是192.168.1.177

yum -y install vim wget epel-release

systemctl disable --now firewalld

systemctl disable --now dnf-makecache.timer

setenforce 0

sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g’ /etc/selinux/config

安装软件包

yum -y install rsync rsync-daemon httpd dnsmasq tftp tftp-server cobbler pykickstart ipxe-bootimgs-x86

yum -y install samba ipxe-roms-qemu.noarch # Windows需要使用

启动服务

systemctl enable --now httpd cobblerd rsyncd tftp

修改cobbler配置

sed -i ‘s/manage_dhcp: false/manage_dhcp: true/’ /etc/cobbler/settings.yaml

sed -i ‘s/manage_dhcp_v4: false/manage_dhcp_v4: true/’ /etc/cobbler/settings.yaml

sed -i ‘s/next_server_v4: 127.0.0.1/next_server_v4: 192.168.1.177/’ /etc/cobbler/settings.yaml

sed -i ‘s/redhat_management_permissive: false/redhat_management_permissive: true/’ /etc/cobbler/settings.yaml

sed -i ‘s/server: 127.0.0.1/server: 192.168.1.177/’ /etc/cobbler/settings.yaml

修复一些配置

cobbler check
yum -y install yum-utils
yum -y install syslinux*
cp /usr/share/syslinux/pxelinux.0 /var/lib/cobbler/loaders/
cp /usr/share/syslinux/menu.c32 /var/lib/cobbler/loaders/
cp /usr/share/syslinux/ldlinux.c32 /var/lib/cobbler/loaders/
cp /usr/share/syslinux/libutil.c32 /var/lib/cobbler/loaders/
systemctl restart cobblerd
cobbler sync

修改一些代码

根据 https://github.com/cobbler/cobbler/issues/3473

[root@localhost modules]# grep -nr wlsd sync_post_wingen_ankele.py -C2
81-    b = h.node_add_child(objs, "{65c31250-afa2-11df-8045-000c29f37d88}")
82-    d = h.node_add_child(b, "Description")
83:    # wlsd mod 2
84-    #h.node_set_value(d, {"key": "Type", "t": REG_DWORD, "value": b"\x03\x00\x20\x13"})
85-    h.node_set_value(d, {"key": "Type", "t": REG_DWORD, "value": b"\x03\x00\x20\x10"})
86-    e = h.node_add_child(b, "Elements")
87:    # wlsd add 2
88-    e1 = h.node_add_child(e, "12000002")
89-    h.node_set_value(e1, {"key": "Element", "t": REG_SZ, "value": "\\windows\\system32\\winload.exe\0".encode(encoding="utf-16le"), }, )
--

179-        if is_wimboot:

181-            #distro_path = os.path.join(settings.webdir, "distro_mirror", distro.name)
182-            #kernel_path = os.path.join(distro_path, "boot")
--

305:                # wlsd mod 2
306-                #wim_file_name = '\\Boot\\' + wim_file_name
307-                wim_file_name = '\\Boot\\' + "winpe.wim"

为Windows修改ipxe.template

sed -i ‘s/kernel $kernel_path $kernel_options initrd=initrd.magic/kernel $kernel_path $kernel_options/’ /etc/cobbler/boot_loader_conf/ipxe.template

为Windows配置ipxe

dnsmasq里边应该是指定的ipxe-x86_64.efi这个文件，所以

cp /usr/share/ipxe/ipxe-x86_64.efi /var/lib/tftpboot/ipxe-x86_64.efi

安装wim工具

不然cobbler import时会报错 no /usr/bin/wiminfo found, please install wimlib-utils 以及 No signature matched in /var/www/cobbler/distro_mirror/win2019

yum -y install wimlib-utils

开启Windows

sed -i ‘s/windows_enabled: false/windows_enabled: true/’ /etc/cobbler/settings.d/windows.settings

开启dnsmasq

而不使用dhcp-server，原因是Windows得使用dnsmasq方便指定ipxe

sed -i ‘s/module = managers.isc/module = managers.dnsmasq/’ /etc/cobbler/modules.conf

cat /etc/cobbler/dnsmasq.template

# Cobbler generated configuration file for dnsmasq
# $date
#

# resolve.conf .. ?
#no-poll
#enable-dbus
read-ethers
addn-hosts = /var/lib/cobbler/cobbler_hosts

systemctl enable --now dnsmasq

cobbler sync

cobbler3.3.3安装Windows2019

配置samba

cat >> /etc/samba/smb.conf << EOF

[DISTRO]
comment = Windows distributions
path = /var/www/cobbler/distro_mirror
guest ok = yes
browseable = yes
public = yes
writeable = no
printable = no
locking = no
EOF

systemctl enable --now smb

导入ISO镜像

scp cn_windows_server_2019_x64_dvd_4de40f33.iso 到/root下
mkdir -p /iso/win2019
mount -o ro,loop cn_windows_server_2019_x64_dvd_4de40f33.iso /iso/win2019
cobbler import --path=/iso/win2019 --name=win2019

指定应答文件

cobbler profile edit --name=win2019-x86_64 --autoinstall-meta=“kernel=http://@@http_server@@/cobbler/images/@@distro_name@@/wimboot bootmgr=bootmgr.exe bcd=bcd winpe=winpe.wim answerfile=autounattended.xml”
ln -s /var/www/cobbler/distro_mirror/win2019 /var/www/cobbler/distro_mirror/win2019-x86_64
cobbler sync

替换cobbler sync生成的winpe.wim，然后给wimpe.wim注入命令

cp /root/winpe.wim /var/www/cobbler/images/win2019-x86_64/
/usr/bin/wimupdate /var/www/cobbler/images/win2019-x86_64/winpe.wim --command=“add /root/winpe_inject /Windows/System32/startnet.cmd”

[root@localhost win2019-x86_64]# cat /root/winpe_inject
wpeinit

ping 127.0.0.1 -n 10 >nul
net use z: \\192.168.1.177\DISTRO\win2019-x86_64
set exit_code=%ERRORLEVEL%
IF %exit_code% EQU 0 GOTO INSTALL
echo "Can't mount network drive"
pause
goto EXIT

:INSTALL

z:\sources\setup.exe /unattend:Z:\autounattended.xml
:EXIT
exit

# 解释
# net use z: \\192.168.1.177\DISTRO\win2019-x86_64 表示使用smb协议挂载192.168.1.177的共享目录，可修改此IP

cp winpe.wim /var/lib/tftpboot/images/win2019-x86_64/

下载wimboot

根据https://github.com/cobbler/cobbler/issues/3473

https://github.com/ipxe/wimboot/releases/latest/download/wimboot，
并copy到几个地方
/var/lib/tftpboot
/var/lib/tftpboot/images/win2019-x86_64
/var/www/cobbler/images/win2019-x86_64/

/var/www/cobbler/images/win2019-x86_64/下边共有这几个文件
autounattended.xml bcd boot.sdi bootmgr.exe pxeboot.n12 wimboot winpe.wim

准备好 autounattended.xml，见附件

/var/lib/tftpboot/images/win2019-x86_64/autounattended.xml
/var/www/cobbler/distro_mirror/win2019/autounattended.xml
/var/www/cobbler/images/win2019-x86_64/autounattended.xml

默认从windows启动

vim /var/lib/tftpboot/ipxe/default.ipxe

set menu-timeout 2000
isset ${menu-default} || set menu-default win2019-x86_64

systemctl restart cobblerd

安装Ubuntu20.04.6-live-server

mkdir /iso/ubuntu20046
mount -o loop,ro ubuntu-20.04.6-live-server-amd64.iso /iso/ubuntu20046
cobbler import --path=/iso/ubuntu20046 --name=ubuntu20046
之后/var/lib/tftpboot/pxelinux.cfg/default中便有了ubuntu20046

修改default，添加参数

LABEL ubuntu20046-casper-x86_64
        MENU LABEL ubuntu20046-casper-x86_64
        kernel /images/ubuntu20046-casper-x86_64/vmlinuz
        append initrd=/images/ubuntu20046-casper-x86_64/initrd  hostname=ubuntu20046-casper-x8664 domain=local.lan suite=focal
        ipappend 2

改为

LABEL ubuntu20046-casper-x86_64
        MENU LABEL ubuntu20046-casper-x86_64
        kernel /images/ubuntu20046-casper-x86_64/vmlinuz
        initrd /images/ubuntu20046-casper-x86_64/initrd
        append biosdevname=0 net.ifnames=0 netcfg/choose_interface=auto ip=dhcp autoinstall ds='nocloud-net;s=http://192.168.1.177:3003/' cloud-config-url=http://192.168.1.177:3003/user-data url=http://192.168.1.177/cobbler/isos/ubuntu-20.04.6-live-server-amd64.iso
        ipappend 2
# 其中biosdevname=0 net.ifnames=0 在live阶段起作用。欲修改安装后系统的网卡名称，cloud-init的user-data中使用shell命令来配置内核参数
# netcfg/choose_interface=auto ip=dhcp 表示任意选中一张网卡，通过DHCP获取IP，用以与我们的server通信
# autoinstall 指定自动安装
# ds='nocloud-net;s=http://192.168.1.177:3003/' 指定安装方式是nocloud-net，并给出包含user-data和meta-data的http静态路径
# cloud-config-url=http://192.168.1.177:3003/user-data 给出user-data具体路径，方便获取cloud-init指令
# url=http://192.168.1.177/cobbler/isos/ubuntu-20.04.6-live-server-amd64.iso 指定网络安装时局域网内的ISO文件路径

mkdir /iso/centos7
mount -o loop,ro CentOS-7-x86_64-Everything-2009.iso /iso/centos7/
cobbler import --path=/iso/centos7 --name=centos7
准备好centos7.ks，修改里边的IP
cobbler profile edit --name centos7-x86_64 --autoinstall centos7.ks

<p>inspect的作用是在安装操作系统之前获取物理机的MAC地址，这里我在192.168.1.177上搞了一个restful接口，用于接收来自inspect的主机的MAC地址信息，然后便可以实现通过system来固定裸机要安装什么操作系统以及要给裸机什么IP了（指定IP目前仅支持Centos），这里可以跳过不看</p>

<h2><a name="t29"></a><a id="_1023"></a>注意</h2> 
<h3><a name="t30"></a><a id="_1025"></a>错误</h3> 
<p>局域网中有路由器，路由器开启了dhcp，虽然第一次获取IP地址时，需要tftp，而必须走我们的dnsmasq，但后续dhcp ack时，有可能因为路由器给了一个IP地址，用此IP作为dhcp ack会报错，然后被dnsmasq拒绝掉<br> dnsmasq报错：DHCPNAK(ens3) 192.168.1.106 f0:1f:af:f0:da:6a wrong server-ID<br> 所以，还是直接关掉路由器dhcp，保证局域网中只有一个dhcp服务器</p>
