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

问题4

启动rsyncd服务

[root@m01 ~]# systemctl start rsyncd
[root@m01 ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

问题5

提示没有安装debmirror包，需要管理debian部署和存储库（可以忽略）

问题6

提示更改密码

[root@m01 ~]# openssl passwd -1 -salt "123" "123456"
$1$123$7mft0jKnzzvAdU4t0unTG1
并把把新生成的密码写入到/etc/cobbler/settings中，所处101行
default_password_crypted: "$1$123$7mft0jKnzzvAdU4t0unTG1"

问题7

可以忽略

distro : 发行版, 就是我们安装什么版本的linux操作系统的名称 一会我们会导入一个 distro.
profile : 类似于一个 配置文件，类似于你的 bash_profile， 里面包含你可以添加 kernel 参数，对应的kickstart 文件 以及 此profile 对应的 distro 等等.

准备kickstart文件

在root目录下找到ks文件，并移动到/var/lib/cobbler/kickstarts/到目录下改名为ks.cfg或者使用下面的

主机名默认是localhost
修改方式，在配置文件中添加
network --hostname=test
修改网卡名称从eth0开始技术 ######CentOS7默认是ens33开始计数，

选择相应操作系统回车执行下一步

等待自动安装结束

装机页面自定义

[root@m01 ~]# cat /etc/cobbler/pxe/pxedefault.template
DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | http://cobbler.github.io/
TIMEOUT 200
TOTALTIMEOUT 6000

        MENU LABEL (local)
        MENU DEFAULT
        LOCALBOOT -1

$pxe_menu_items

MENU end

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..
