#环境检查后发现又少了一条，下面接这来...
1 : change 'disable' to 'no' in /etc/xinetd.d/tftp
2 : 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.
3 : enable and start rsyncd.service with systemctl
4 : debmirror package is not installed, it will be required to manage debian deployments and repositories
5 : 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
6 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
如上第一条：提示更改/etc/xinetd.d/tftp配置文件中'disable'状态改为‘no’说白了也就是开启tftp服务
因为我们用的是centos7不需要xinetd.d了，前面已经开启了tftp服务，这步忽略，看下一个提示
第二条：在/var/lib/cobbler/loaders目录下少了一些必要的文件，用'cobbler get-loaders' 命令来获取，这时候需要主机联网下载
cobbler get-loaders
我们先来看看这个目录
①生成必要文件
我们知道出现的这些文件是要放在/var/lib/tftpboot/这里的，我们看下这个目录的信息
用如上环境检查中给出的提示进行同步
cobbler sync
#数据同步
再次查看下/var/lib/tftpboot目录结构
②重复步骤一中的②命令
#又少了，继续
1 : enable and start rsyncd.service with systemctl
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
3 : 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
4 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
步骤四
第一条：开启rsyncd.service 服务，我们没有用这个服务，忽略
第二条：是针对debian发行版的系统配置，忽略
第三条：修改kickstart文件的默认口令
①编辑配置文件
vim /etc/cobbler/settings
#
②重复步骤一中的②命令
