安裝系統(tǒng)時的應答文件,其中包括在典型安裝過程中可能會問的所有問題的答案。
Kickstart Configurator 允許使用圖形用戶界面創(chuàng)建和修改 kickstart 文件,這樣就需要記住文件的正確語法。
默認情況下,不會在 Red Hat Enterprise Linux 6 中安裝 Kickstart Configurator。運行yum install system-config-kickstart,或使用圖形化軟件包管理器安裝這個軟件。
要啟動 Kickstart Configurator,請將系統(tǒng)引導至圖形環(huán)境,然后運行 system-config-kickstart,或在 GNOME 桌面上點擊 應用程序 → 系統(tǒng)工具 → Kickstart,或者在 KDE 桌面上點擊 開始應用程序啟動器+應用程序 → 系統(tǒng) → Kickstart。
創(chuàng)建 kickstart 文件時,可以在任何時候選擇 File → Preview 查看當前的選擇。
要修改現(xiàn)有的 kickstart 文件,選擇 File → Open File,并選擇文件。

[root@CentOS7-01 ~]#systemctl enable --now cobblerd httpd tftp dhcpd
這里報dhcpd服務錯誤,是因為還沒有配置相關文件,先不用管,繼續(xù)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.
