第2章 Cobbler工具介绍
2.1 简介
Cobbler是一个Linux服务器安装的服务，可以通过网络启动(PXE)的方式来快速安装、重装物理服务器和虚拟机，同时还可以管理DHCP，DNS等。
Cobbler可以使用命令行方式管理，也提供了基于Web的界面管理工具(cobbler-web)，还提供了API接口，可以方便二次开发使用。Cobbler是较早前的kickstart的升级版，优点是比较容易配置，还自带web界面比较易于管理。
Cobbler内置了一个轻量级配置管理系统，但它也支持和其它配置管理系统集成，如Puppet，暂时不支持SaltStack。
2.2 支持的服务
PXE服务支持
DHCP服务管理
DNS服务管理(可选bind,dnsmasq)
电源管理
Kickstart服务支持
YUM仓库管理
TFTP(PXE启动时需要)
Apache(提供kickstart的安装源，并提供定制化的kickstart配置

4.1 解决上面的报错
[root@cobbler ~]# /etc/init.d/cobblerd restart
Stopping cobbler daemon: [确定]
Starting cobbler daemon: [确定]
[root@cobbler ~]# cobbler check
The following are potential configurationitems 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 : change 'disable' to 'no' in/etc/xinetd.d/tftp
4 : 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.
5 : change 'disable' to 'no' in/etc/xinetd.d/rsync
6 : file /etc/xinetd.d/rsync does not exist
7 : debmirror package is not installed,itwill be required to manage debian deployments and repositories
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.
4.2 配置rsync
sed -i -e 's/\=\ yes/\=\ no/g'/etc/xinetd.d/rsync
service xinetd restart
4.2.1 执行结果
[root@cobbler ~]# sed -i -e 's/\=\ yes/\=\ no/g' /etc/xinetd.d/rsync
[root@cobbler ~]# service xinetd restart
停止 xinetd： [确定]

镜像存放目录，cobbler会将镜像中的所有安装文件拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS-6.7-x86_64目录下。因此/var/www/cobbler目录必须具有足够容纳安装文件的空间。

第9章 开机自启动
因后边会把他写入到内核里，所以，小心开启选择顺序
9.1 修改grub，更改启动项
9.1.1 备份grub配置文件
因etc目录下面的grub.conf是一个链接文件，需要备份原始文件.修改链接文件无效！！！
[root@cobbler ~]# ls -l /etc/grub.conf
lrwxrwxrwx. 1 root root 22 5月 22 13:44 /etc/grub.conf -> ../boot/grub/grub.conf
[root@cobbler ~]# cp -a /boot/grub/grub.conf /boot/grub/grub.conf.bak
[root@cobbler ~]# ls -l /boot/grub/grub*
-rw------- 1 root root 1463 6月 10 02:22 /boot/grub/grub.conf
-rw------- 1 root root 1463 6月 10 02:22 /boot/grub/grub.conf.bak
9.1.2 编辑grub配置文件
以“title”为首的项目，每一个这样的项目，就是我们安装的操作系统，如果我们想让哪个为默认启动操作系统，那么我们需要修改“default”的值，这个值按照数组方式来设置，设置的值为我们系统中实际操作系统数量-1，例如我们现在有两个操作系统，我们想设置第一个为默认操作系统，那么我们应该把这个值设置为0；如果想第二个为默认操作系统，那么应该设置这个值为1
9.1.2.1查看grub配置文件
[root@cobbler ~]# cat /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grubafter making changes to this file
# NOTICE:You have a /boot partition. Thismeans that

9.1.3 重启测试
9.2 开机手动执行脚本（启动服务）
这样做的目的是为了避免在同一网段的机器被错误装系统！
cat >/server/scripts/cobbler_service.sh<<EOF
#!/bin/sh
/etc/init.d/httpd restart
/etc/init.d/cobblerd restart
/etc/init.d/xinetd restart
/etc/init.d/dhcpd restart
EOF
chmod +x /server/scripts/cobbler_server.sh
ls -l /server/scripts/cobbler_service.sh
9.3 执行结果
[root@cobbler ~]# cat >/server/scripts/cobbler_service.sh<<EOF
> #!/bin/sh
> /etc/init.d/httpd restart
> /etc/init.d/cobblerd restart
> /etc/init.d/xinetd restart

[root@cobbler ~]# ls -l /server/scripts/cobbler_service.sh
