CentOS Cobbler故障排除可按以下步驟進行：
cobblerd、httpd、tftp、dhcp等服務已啟動并開機自啟。systemctl status cobblerd httpd tftp dhcp
systemctl enable cobblerd httpd tftp dhcp
cobbler check命令排查配置文件錯誤，重點關注/etc/cobbler/settings中server、next_server等字段是否正確。tail -f /var/log/cobbler/cobbler.log獲取詳細錯誤信息。/etc/cobbler/dhcp.template中IP段、網關、DNS等參數是否正確。/etc/xinetd.d/tftp中disable=no。systemctl stop firewalld
setenforce 0
cobbler-web。cobbler sync使更改生效。pxelinux.0等引導文件是否存在于/var/lib/tftpboot/。net.ifnames=0參數，或修改/etc/default/grub配置。若問題仍未解決，可參考Cobbler官方文檔或社區論壇獲取進一步支持。
