安装系统时的应答文件，其中包括在典型安装过程中可能会问的所有问题的答案。
Kickstart Configurator 允许使用图形用户界面创建和修改 kickstart 文件，这样就需要记住文件的正确语法。
默认情况下，不会在 Red Hat Enterprise Linux 6 中安装 Kickstart Configurator。运行yum install system-config-kickstart，或使用图形化软件包管理器安装这个软件。
要启动 Kickstart Configurator，请将系统引导至图形环境，然后运行 system-config-kickstart，或在 GNOME 桌面上点击 应用程序 → 系统工具 → Kickstart，或者在 KDE 桌面上点击 开始应用程序启动器+应用程序 → 系统 → Kickstart。
创建 kickstart 文件时，可以在任何时候选择 File → Preview 查看当前的选择。
要修改现有的 kickstart 文件，选择 File → Open File，并选择文件。

[root@CentOS7-01 ~]#yum install cobbler dhcp tftp httpd -y
[root@CentOS7-01 ~]#systemctl enable --now cobblerd httpd tftp dhcpd
这里报dhcpd服务错误，是因为还没有配置相关文件，先不用管，继续往下做[root@CentOS7-01 ~]#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 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : ksvalidator was not found, install pykickstart
8 : 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
9 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
Restart cobblerd and then run 'cobbler sync' to apply changes.server: 192.168.7.71next_server: 192.168.7.71disable = nomanage_dhcp: 1[root@CentOS7-01 ~]#cobbler get-loaderssubnet 192.168.7.0 netmask 255.255.255.0 {
