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 : change 'disable' to 'no' in /etc/xinetd.d/tftp
4 : 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.
5 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : 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
8 : 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.
一步步解决上述需求，部分需求可忽略。个体差异不同 每个人需求数量也不同，基本上大同小异
解决需求1、2、7
# openssl passwd -1 -salt 'werwqerwqr' '123456' --123456为密码(这是自动安装客户端系统成功后的root登录密码）,werwqerwqr为随机字节干扰码（随便写）
$1$werwqerw$.prcfrYFbwuvkD8XspayN.
# vim /etc/cobbler/settings
384 server: 192.168.100.221 --换成cobbler服务器端的IP
272 next_server: 192.168.100.221 --同上
101 default_password_crypted: "$1$werwqerw$.prcfrYFbwuvkD8XspayN." --把密码字符串换成你上面产生的字符串(此密码为客户机安装后的root登录密码)
解决需求3
# vim /etc/xinetd.d/tftp
disable = no --yes改为no
解决需求5
#systemctl restart rsyncd.service
#systemctl enable rsyncd.service
解决需求8
# yum install fence-agents
OK,剩下的需求像
4 : 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.
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
（问题4可以使用cobbler get-loaders解决，但需要有外网和外网的yum源 跳过，现在是NAT模式；问题6 是关于debian系统的，我们这里可以忽略）
最后# systemctl restart cobblerd.service 重起下cobbler补鞋匠服务！
三.导入centos7.3的iso镜像
我的环境iso镜像挂载在/yum目录，此拷贝步骤时间较长
# cobbler import --path=/yum/ --name=centos7.3
# cobbler distro list --导入成功后，确认导入的镜像名
centos7.3-x86_64
# cobbler profile list --导入成功后，确认默认的profile名
centos7.3-x86_64
