Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
The program yum-complete-transaction is found in the yum-utils package.

配置tftp服务
[root@m01 ~]# cat /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no ######将默认的'yes'改为'no'
per_source = 11
cps = 100 2
flags = IPv4
[root@m01 ~]# systemctl restart xinetd.service
[root@m01 ~]# systemctl enable xinetd.service
[root@m01 ~]# systemctl restart httpd
[root@m01 ~]# systemctl enable httpd
[root@m01 ~]# systemctl restart cobblerd
[root@m01 ~]# systemctl enable cobblerd
[root@m01 ~]# sed -i 's#manage_dhcp: 0#manage_dhcp: 1#g' /etc/cobbler/settings
配置cobbler
运行cobbler chec得出以下提示
[root@m01 ~]# 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 : 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.
4 : enable and start rsyncd.service with systemctl
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : 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
7 : 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.
问题1
cobbler文件默认是127.0.0.1本地回环地址，需要更改为提供cobbler服务的ip地址 10.0.0.61,在384行
sed -i 's#server: 127.0.0.1#server: 10.0.0.61#g' /etc/cobbler/settings
[root@m01 ~]# sed -i 's#server: 127.0.0.1#server: 10.0.0.61#g' /etc/cobbler/settings
问题2
netx_server也是默认本地127.0.0.1回环地址，需要修改为提供cobbler服务的ip地址 192.163.182,128，在272行
sed -i 's#next_server: 127.0.0.1#next_server: 10.0.0.61#g' /etc/cobbler/settings
[root@m01 ~]# sed -i 's#next_server: 127.0.0.1#next_server: 10.0.0.61#g' /etc/cobbler/settings
问题3
提示让执行cobbler get-loaders命令，执行下就好了。（可以忽略）

修改完配置文件后一定要执行 cobbler sync
根据MAC地址设置固定IP
[root@m01 ~]# cobbler system add --name=test --mac=00:50:56:29:32:09 --profile=CentOS7.6 --ip-address=10.0.0.200 subnet=255.255.255.0 --gateway=10.0.0.254 --interface=eth0 --static=1 --hostname=nginx
设置完成后curl http://10.0.0.61/cblr/svc/op/ks/system/test 得到ks配置文件
建议内存大于3G否则可能会产生不可预知的错误
如果无法下载ks文件检查所有服务状态是否正常
httpd dhcpd xinetd tftp 等..
