导读：Cobbler介绍 Cobbler 是一个系统启动服务（boot server），可以通过网络启动（PXE）的方式用来快速安装、重装物理服务器和虚拟机，支持安装不同的 Linux 发行版和 Windows。该工具使用python开发，小巧轻便（才15k行代码），使用简单的命令即可完成PXE网络安

如果上述两个命令执行过显示的结果出入较大,则可能文件没有正常导入 在重新导入之前最好先把之前的内容删除再导入 cobbler [distro] remove –name=[CentOS-6.5-x86_64] 方括号中的内容根据自己的情况来填写,更多命令通过cobbler –help 来查看 剩下其它系统导入方法类似，只是名字和路径更改下即可。重复上面的操作，把其他的系统镜像文件导入到Cobbler导入完成之后，可通过 cobbler list 来查看导入的结果。 创建kickstarts自动安装脚本（For Centos/RHEL) 注意：这是关键步骤之一 由于需要安装的操作系统发行厂商不同，因此KS文件的写法要求，也不一而足。 本文只讨论 CentOs/RHEL 系列的 KS配置 另外：操作系统 版本不同，KS也存在一定的差异，比如CentOS5,和CentOS6下就有不同，切记！ 官网的文档在此: CentOS5 的 (网上大多是这个系列的) : http://www.centos.org/docs/5/html/Installation_Guide-en-US/s1-kickstart2-options.html CentOS6 的 (能看到的配置案例很少) : https://access.redhat.com/kNowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/s1-kickstart2-options.html 默认kickstart文件是/var/lib/cobbler/kickstarts/sample.ks，需要手动为每个发行版单独指定，或单独修改。 自定义ks文件，下面是我自己定义的一个centos6.5模板

注意：kickstarts自动安装脚本中不允许有中文（注释有中文也不行），否则会报错 修改profile指定新的KS启动文件 按照操作系统版本分别关联系统镜像文件和kickstart自动安装文件 在第一次导入系统镜像时，cobbler会给安装镜像指定一个默认的kickstart自动安装文件 例如：CentOS-6.5-x86_64版本的kickstart自动安装文件为：/var/lib/cobbler/kickstarts/sample.ks （编辑：十堰站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
