环境
[root@cobbler ~]# cat /etc/centos-release
CentOS Linux release 7.5.1804 (Core)
[root@cobbler ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
[root@cobbler ~]# getenforce
Disabled
[root@cobbler ~]# hostname
cobbler
[root@cobbler ~]# hostname -I
10.0.0.206 172.16.1.206
PS:虚拟机的dhcp关闭
安装cobbler
yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django --下载一些需要的软件
[root@cobbler ~]# cobbler check
cobblerd does not appear to be running/accessible: error(111, 'Connection refused')
这里报了一个错，
解决
[root@cobbler ~]# systemctl start httpd.service
[root@cobbler ~]# systemctl start cobblerd.service
继续执行cobbler check
[root@cobbler ~]# 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()
还是报了一个错，截取一部分
解决
发现是selinux开启了，关闭就好
setenforce 0 --临时关闭
vim /etc/selinux/config
修改 SELINUX=disabled --永久关闭
继续执行cobbler
[root@cobbler ~]# 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.
一个个解决
1 2 6
vim /etc/cobbler/settings
next_server: 172.16.1.206
default_password_crypted: "$1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1"
server: 172.16.1.206
将这三项修改一下，按照自己的实际情况，密码是通过openssl passwd -1 -salt 'oldboy' '123456' 加密得出的密文，明文为“123456”

[root@cobbler ~]# vim /etc/xinetd.d/rsync
disable = no
还有两个是不用修改的
配置dhcp
修改cobbler的dhcp模板，不要直接修改dhcp服务本身的配置文件，cobbler会将其覆盖掉
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

完成之后开启虚拟机，等待一段时间即可。时间长短看自己电脑配置了
