The following are potential configuration items that you may want to fix: 8. 9. 1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting 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. 10. 2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network. 11. 3 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, 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, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements. 12. 4 : change 'disable' to 'no' in /etc/xinetd.d/rsync 13. 5 : debmirror package is not installed, it will be required to manage debian deployments and repositories 14. 6 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one 15. 7 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them 16. 17. Restart cobblerd and then run 'cobbler sync' to apply changes. 18. 19. # 看着上面的结果,一个一个解决。 20. # 第一、二、6个问题,顺便修改其余功能 21.
