[root@linuxidc cobbler]# cobbler check The following are potential configuration items that you may want to fix: 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. 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. 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. 4 : change 'disable' to 'no' in /etc/xinetd.d/rsync 5 : comment out 'dists' on /etc/debmirror.conf for proper debian support 6 : comment out 'arches' on /etc/debmirror.conf for proper debian support 7 : ksvalidator was not found, install pykickstart 8 : 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 9 : 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.
第一和第二个问题：
[root@linuxidc cobbler]# vim /etc/cobbler/settings next_server: 172.16.10.10 server: 172.16.10.10
第三个问题：获取pxelinux.0和menu.c32文件(对于centos来说只需这两个文件)，可以像pxe一样从syslinux包中手动复制到/var/lib/cobbler/loaders目录下，也可以执行cobbler get-loaders自动下载，但要求联网。
[root@linuxidc cobbler]# cobbler get-loaders
第四个问题：有可能该问题不是如此的，而是说要将rsyncd.service使用给start且enable，只需systemctl enable rsyncd，systemctl start rsyncd。
[root@linuxidc cobbler]# vim /etc/xinetd.d/rsync disable=no
[root@linuxidc cobbler]# service xinetd start
第5、6个问题，注释掉/etc/debmirror.conf中相关项即可。
第7个问题：因为之前安装的时候写成了pykicstart，所以出错了这里。
[root@linuxidc cobbler]# yum -y install pykickstart
第8个问题：
