Rocky部署Cobbler

1、安装软件

cobbler版本3.3.3  rockyliux9.2

[root@wenzi ~]#dnf -y install cobbler dhcp-server
[root@wenzi ~]#systemctl enable --now cobblerd tftp.service httpd dhcpd

2、配置cobbler

cobbler配置检查

[root@wenzi ~]#cobbler check
The following are potential configuration items that you may want to fix:

1: The 'server' field in /etc/cobbler/settings.yaml must be set to something other than localhost, or automatic installation features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2: For PXE to be functional, the 'next_server_v4' field in /etc/cobbler/settings.yaml must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3: For PXE to be functional, the 'next_server_v6' field in /etc/cobbler/settings.yaml must be set to something other than ::1, and should match the IP of the boot server on the PXE network.
4: some network boot-loaders are missing from /var/lib/cobbler/loaders. If you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, andmenu.c32.
5: reposync is not installed, install yum-utils or dnf-plugins-core
6: yumdownloader is not installed, install yum-utils or dnf-plugins-core
7: debmirror package is not installed, it will be required to manage debian deployments and repositories
8: ksvalidator was not found, install pykickstart
9: The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings.yaml) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
10: fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.

根据check结果提示安装相关包

[root@wenzi ~]#dnf -y install syslinux dnf-plugins-core pykickstart
#使用md5加密生成密码，用于下面cobbler配置文件
[root@wenzi ~]#openssl passwd -1
Password:
Verifying - Password:
$1$L9q17zY8$VGlrtSiCN5IkRnqkpEB/o1

修改cobbler主配置文件 

[root@wenzi ~]#vim /etc/cobbler/settings.yaml
...
#新装系统的root密码
default_password_crypted: "$1$L9q17zY8$VGlrtSiCN5IkRnqkpEB/o1"
...
#使用cobbler管理dhcp
manage_dhcp: true
...
manage_dhcp_v4: true
...
#tftp地址
next_server_v4: 192.168.28.128
...
#cobbler服务器地址
server: 192.168.28.128
...
#使用cobbler管理tftp
manage_tftpd: true
...
#当bios首选启动项是pxe时，此项设置为true，可避免重启反复安装系统，否则为false
pxe_just_once: true
...

修改dhcp模版文件

[root@wenzi ~]#vim /etc/cobbler/dhcp.template
...
subnet 192.168.28.0 netmask 255.255.255.0 {
     option routers             192.168.28.2;
     option domain-name-servers 223.5.5.5,180.76.76.76;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.28.130 192.168.28.254;
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server_v4;
...

重启cobblerd、dhcpd、tftp.service、httpd；cobbler同步配置

[root@wenzi ~]#systemctl restart cobblerd httpd tftp.service dhcpd
[root@wenzi ~]#cobbler sync

修改启动菜单模版

菜单标题为：Wenzi Cobbler Menu。

[root@wenzi ~]#vim /etc/cobbler/boot_loader_conf/pxe_menu.template
DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | Wenzi Cobbler Menu

生成引导加载程序 cobbler mkloaders 此命令适用cobblerV3.3.1及之后的版本。

此命令不执行的话新建虚拟机(无cd/dvd)开机会提示pxe-T01:file not found

[root@wenzi ~]#cobbler mkloaders
[root@wenzi ~]#ls /var/lib/cobbler/loaders/
grub  ldlinux.c32  libutil.c32  memdisk  menu.c32  pxelinux.0

测试出现问题，后查询许久发现已经有人在github上反馈了该bug，暂未修复
