Cobbler check检查解决以下问题：
[[email protected]_1 ~]# 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 : 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 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync
6 : since iptables may be running, ensure 69, 80/443, and 25151 are unblocked
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : ksvalidator was not found, install pykickstart
9 : 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
10 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
解决：
1、 修改/etc/cobbler/settings文件中的server参数的值为提供cobbler服务的主机相应的IP地址或主机名，10.0.0.61
2、 修改/etc/cobbler/settings文件中的next_server参数的值为提供PXE服务的主机相应的IP地址 ，10.0.0.61
3、 change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
4、 如果当前节点可以访问互联网，执行“cobbler get-loaders”命令即可；否则，需要安装syslinux程序包，而后复制/usr/share/syslinux/{pxelinux.0,memu.c32}等文件至/var/lib/cobbler/loaders/目录中
5、 change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync
6、 关闭防火墙或开放端口69, 80/443, and 25151
7、 Yum installdebmirror
8、 Yum installpykickstart
9、 执行“openssl passwd -1 -salt $(openssl rand -hex 4)”生成密码，并用其替换/etc/cobbler/settings文件中default_password_crypted参数的值；
10、 yum install cman fence-agents
解决完成后重启cobblerd

解决方法：
修改hosts 文件在 127.0.0.1 localhost.localdomainlocalhost 添加本机的主机名
127.0.0.1 localhost.localdomainlocalhost wdds_1
待续。。。
后续添加cobbler_web认证等
