$$$$$$$$$$$$$$$$$$$问题2：
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 ：you need to set some SELinux content rules to ensure cobbler works correctly in your SELinux environment, run the following:
/usr/sbin/semanage fcontext -a -t public_content_t "/tftpboot/.*" && \
/usr/sbin/semanage fcontext -a -t public_content_t "/var/www/cobbler/images/.*"
5 : change 'disable' to 'no' in /etc/xinetd.d/rsync
change 'disable' to 'no' in /etc/xinetd.d/tftp
6 : comment out 'dists' on /etc/debmirror.conf for proper debian support
comment out 'arches' on /etc/debmirror.conf for proper debian support
7 ：since iptables may be running, ensure 69, 80, and 25151 are unblocked
8 : The default pass<a href="http://www.it165.net/edu/ebg/" target="_blank" class="keylink">word</a> used by the sample templates for newly installed machines (default_pass<a href="http://www.it165.net/edu/ebg/" target="_blank" class="keylink">word</a>_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.
9，debmirror package is not installed, it will be required to manage debian deployments and repositories
$$$$$$$$$$$$$$$$$$$$$上面这段信息大意就是：
1，编辑/etc/cobbler/settings文件，找到 server：选项，修改为适当的ip地址，本实例配置ip为：192.168.10.1
2，编辑/etc/cobbler/settings文件，找到 next_server：选项，修改为适当的ip地址，本实例配置ip为：192.168.10.1
4，SELinux的设置。如果上面已经关闭了SELinux就不用管了，SELinux的设置。如果上面已经关闭了SELinux就不用管了
3，执行 cobbler get-loaders，系统将自动下载loader程序，完成提示4的修复工作。
5，编辑/etc/xinetd.d/tftp文件，将文件中的disable字段的配置由yes改为no
编辑/etc/xinetd.d/rsync文件，将文件中的disable字段的配置由yes改为no
6. 在/etc/debmirror.conf文件中注释dists和arches
7，在iptables中将69，80，25151端口打开。如果仅仅只是在内部环境中使用，建议直接将防火墙关掉
9，提示说debmirror没安装。如果不是安装 debian之类的系统，此提示可以忽略，如果需要安装，下载地址为：
http://rpmfind.net/linux/rpm2html/search.php?query=debmirror
CentOS 6使用RHEL 5的包就可以。
8，修改cobbler用户的默认密码，可以使用如下命令生成密码，并使用生成后的密码替换/etc/cobbler/settings （default_password_crypted: ）中的密码。生成密码命令：
openssl passwd -1 -salt '用户' '密码'
其中“random-phrase-here”为干扰码
