[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1: SELinux is enabled. Please review the following wiki page for details on ensuring Cobbler works correctly in your SELinux environment:
https://github.com/cobbler/cobbler/wiki/Selinux
2: 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.
3: reposync is not installed, install yum-utils or dnf-plugins-core
4: yumdownloader is not installed, install yum-utils or dnf-plugins-core
5: debmirror package is not installed, it will be required to manage debian deployments and repositories
6: 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.
#问题1解决办法：
[root@localhost ~]# 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/
[root@localhost ~]# ls /var/lib/cobbler/loaders/
menu.c32 pxelinux.0
#问题2和问题三的解决办法：
[root@localhost ~]# yum -y install yum-utils
#问题4和问题5可以忽略，
因为是debian系统才需要解决，显示使用的是centos8
Debian系统解决办法安装fence-agents
#配置DHCP模板文件
[root@localhost ~]# vim /etc/cobbler/dhcp.template

进行测试
安装一个空壳centos8的虚拟机，不需要给镜像
进来后就发现可以自动获取ip选择我们刚才上传的镜像
正在安装包
安装完成，登录查看ip
