1.设置新系统默认密码
[root@localhost ~]# openssl passwd -1

$1$NBSwa0Xy$VweeQYaNbeBlNNZyW5ztb/修改配置文件 /etc/cobbler/settings.yaml
default_password_crypted: "$1$NBSwa0Xy$VweeQYaNbeBlNNZyW5ztb/"2.1配置server,该配置为cobbler服务器的ip
server: 10.66.8.1112.2配置next_server，该配置为dhcp/pxe作为下载网络引导文件的tftp服务器的ip，通常和cobbler服务器设置相同的ip
next_server: 10.66.8.1113.配置dhcp管理
manage_dhcp: true修改dhcp模板文件
vim /etc/cobbler/dhcp.template修改内容如下
subnet 10.66.8.0 netmask 255.255.255.0 {
option routers 10.66.0.1;
option domain-name-servers 10.66.0.1;
option subnet-mask 255.255.255.0;

}4.启动cobbler服务
[root@localhost ~]# systemctl start cobblerd
[root@localhost ~]# systemctl status cobblerd

Aug 29 22:52:53 localhost.localdomain systemd[1]: Started Cobbler Helper Daemon.5.检查问题，并且进行同步
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1: dhcpd is not installed
2: some network boot-loaders are missing from /var/lib/cobbler/loaders. 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, and yaboot.
3: reposync is not installed, install yum-utils or dnf-plugins-core
4: yumdownloader is not installed, install yum-utils or dnf-plugins-core
5: debmirror package is not installed, it will be required to manage debian deployments and repositories
6: ksvalidator was not found, install pykickstart
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.有七个问题，需我们进行解决
# 问题1: dhcpd is not installed
dnf install dhcp-server -y
#问题2
dnf install syslinux -y
cp /usr/share/syslinux/{pxelinux.0,menu.c32} /var/lib/cobbler/loaders/
# 问题3，4: reposync is not installed, install yum-utils or dnf-plugins-core
dnf install yum-utils -y
#问题5可以忽略
# 问题6，7: ksvalidator was not found, install pykickstart
dnf install pykickstart fence-agents -y同步并再次测试
cobbler sync
cobbler check第一个已经配置过了，不知道为啥还提示，第二个可以忽略
