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 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.
6 : enable and start rsyncd.service with systemctl
7 : comment out ‘dists‘ on /etc/debmirror.conf for proper debian support
8 : comment out ‘arches‘ on /etc/debmirror.conf for proper debian support
9 : 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

Restart cobblerd and then run ‘cobbler sync‘ to apply changes.

修改server的ip地址为本机ip
sed -i ‘s/server: 127.0.0.1/server: 192.168.2.254/g‘ /etc/cobbler/settings

修改TFTP Server 的IP地址
sed -i ‘s/^next_server: 127.0.0.1/next_server: 192.168.2.254/‘ /etc/cobbler/settings
sed ‘14s/yes/no/g‘ /etc/xinetd.d/tftp -i
systemctl restart xinetd

启动rsyncd服务并设置为开机启动
[root@localhost ~]# systemctl enable rsyncd
[root@localhost ~]# systemctl start rsyncd

下载缺失的文件
[root@localhost ~]# cobbler get-loaders

生成密码
openssl passwd -1 -salt $(openssl rand -hex 4) 123456
$1$3a96551b$ma1wWqgi0lHpKLugVhUC31

修改settings配置文件中下面位置，把新生成的密码加进去
grep -n \_password /etc/cobbler/settings 
101:default_password_crypted: "$1$3a96551b$ma1wWqgi0lHpKLugVhUC31"

注释28，30行
grep -En "sid|i386" /etc/debmirror.conf
28:#@dists="sid";
30:#@arches="i386";

重启COBBLER服务
[root@localhost ~]# systemctl restart cobblerd

在用COBBLER检测一次，以下SELINUX可忽略

1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
