#查看cobbler
[root@localhost ~]# dnf module list |grep cobbler
cobbler              3               default [d]        Versatile Linux deployment server                                                                                                                                   cobbler              3.3             default            Versatile Linux deployment server

三.设置开机自启

[root@localhost ~]# systemctl enable --now httpd
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.
[root@localhost ~]# systemctl enable --now cobblerd
Created symlink /etc/systemd/system/multi-user.target.wants/cobblerd.service → /usr/lib/systemd/system/cobblerd.service.
[root@localhost ~]# systemctl enable --now rsyncd
Created symlink /etc/systemd/system/multi-user.target.wants/rsyncd.service → /usr/lib/systemd/system/rsyncd.service.

##修改/etc/cobbler/settings.yaml
[root@localhost ~]# vim /etc/cobbler/settings.yaml

#修改默认密码
default_password_crypted: "$1$random-p$VAxQnB8rJAXUWAm0cIy.D1" 

server: 192.168.192.131 #修改为本机ip
next_server: 192.168.192.131

manage_dhcp: true #开启dhcp

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

1: 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, menu.c32, and yaboot.
2: reposync is not installed, install yum-utils or dnf-plugins-core
3: yumdownloader is not installed, install yum-utils or dnf-plugins-core
4: debmirror package is not installed, it will be required to manage debian deployments and repositories
5: 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.


解决方法:
yum -y install yum-utils
yum -y install syslinux
[root@localhost ~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/cobbler/loaders/
[root@localhost ~]# cp /usr/share/syslinux/menu.c32 /var/lib/cobbler/loaders/
