所需服務
PXE服務支援
DHCP服務管理
DNS服務管理(可選bind,dnsmasq)
電源管理
Kickstart服務支援
YUM倉庫管理
TFTP(PXE啟動時需要)
Apache(提供kickstart的安裝源，並提供定製化的kickstart配置)
環境
[[email protected] ~]# cat /etc/centos-release

[ 安裝cobbler
yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django --下載一些需要的軟體
[[email protected] 解決
[[email protected] ~]# systemctl start httpd.service
[[email protected] ~]# systemctl start cobblerd.service
繼續執行cobbler check
[[email protected] ~]# cobbler check httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback: Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/cobbler/cli.py", line 251, in check_setup s.ping() 還是報了一個錯，擷取一部分
解決
發現是selinux開啟了，關閉就好
setenforce 0 --臨時關閉
vim /etc/selinux/config
修改 SELINUX=disabled --永久關閉
繼續執行cobbler
[[email protected] ~]# 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 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
https://github.com/cobbler/cobbler/wiki/Selinux
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp
5 : 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 wa to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and ya▽oot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
6 : enable and start rsyncd.service with systemctl
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
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.
一個個解決
1 2 6
vim /etc/cobbler/settings
next_server: 172.16.1.206
default_password_crypted: "$1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1"
server: 172.16.1.206
將這三項修改一下，按照自己的實際情況，密碼是通過openssl passwd -1 -salt 'oldboy' '123456' 加密得出的密文，明文為“123456”

[[email protected] ~]# vim /etc/xinetd.d/rsync
disable = no
還有兩個是不用修改的
配置dhcp
修改cobbler的dhcp模板，不要直接修改dhcp服務本身的配置檔案，cobbler會將其覆蓋掉
vim /etc/cobbler/dhcp.template
subnet 172.16.1.0 netmask 255.255.255.0 {
22 option routers 172.16.1.5;
23 option domain-name-servers 172.16.1.1;
24 option subnet-mask 255.255.255.0;
25 range dynamic-bootp 172.16.1.100 172.16.1.254;
sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings --用cobbler 管理dhcp

擷取部分，可以看出他幹了什麼

截圖來自何導，自己沒截。。。內容根據自己實際修改即可
完成之後開啟虛擬機器，等待一段時間即可。時間長短看自己電腦配置了
