linux实现cobbler
Cobbler 可以用来快速建立 Linux 网络安装环境，它已将 Linux 网络安装的技术门槛，从大专以上文化水平，成功降低到初中以下，连补鞋匠都能学会
网络安装服务器套件 Cobbler(补鞋匠)从前，我们一直在做装机民工这份很有前途的职业。自打若干年前 Red Hat 推出了 Kickstart，此后我们顿觉身价倍增。不再需要刻了光盘一台一台地安装 Linux，只要搞定 PXE、DHCP、TFTP，还有那满屏眼花缭乱不知所云的 Kickstart 脚本，我们就可以像哈里波特一样，轻点魔棒，瞬间安装上百台服务器。这一堆花里胡哨的东西可不是一般人都能整明白的，没有大专以上学历，通不过英语四级，根本别想玩转。总而言之，这是一份多么有前途，多么有技术含量的工作啊。很不幸，Red Hat 最新（Cobbler项目最初在2008年左右发布）发布了网络安装服务器套件 Cobbler(补鞋匠)，它已将 Linux 网络安装的技术门槛，从大专以上文化水平，成功降低到初中以下，连补鞋匠都能学会。对于我们这些在装机领域浸淫多年，经验丰富，老骥伏枥，志在千里的民工兄弟们来说，不啻为一个晴天霹雳。

cobbler check 检测cobbler运行的问题
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, orkickstarting features will not work. This should be a resolvable hostname or IP for the boot server asreachable 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 otherthan 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : some network boot-loaders are missingfrom /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to downloadthem, or, if you only want to handle x86/x86_64 netbooting, you may ensure thatyou have installed a *recent* version of the syslinux package installed and canignore this message entirely. Files inthis directory, should you want to support all architectures, should includepxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' commandis the easiest way to resolve these requirements.
4 : change 'disable' to 'no' in/etc/xinetd.d/rsync
5 : since iptables may be running, ensure69, 80/443, and 25151 are unblocked
6 : debmirror package is not installed, itwill be required to manage debian deployments and repositories
7 : ksvalidator was not found, installpykickstart
8 : The default password used by the sampletemplates 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 arerequired to use the (optional) power management features. install cman orfence-agents to use them
Restart cobblerd and then run 'cobblersync' to apply changes.
