The following are potential configuration items that you may want to fix:
1 : 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
2 : change 'disable' to 'no' in /etc/xinetd.d/tftp
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 : 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.
# 如果有“httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:”的提示，那么就重启一下http服务器。
# 这是检查的结果，1是没有关SElinux，实际已经关了；2是需要将/etc/xinetd.d/tftp中的disable改为no。3是没有loader文件，可以运行提示的命令下载，没有必要；4是没有启动rsync服务，实际启动了，监听在873端口；5是与debian相关的，没有用；6是与fence设备相关，不需要

# 导入镜像，生成distro，生成的镜像存在/var/www/cobbler/ks_mirror下。所以/var/www/cobbler要有足够的空间。
# --path 镜像路径
# --name 为安装源定义一个名字
# --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64
# 安装源的唯一标示就是根据name参数来定义，本例导入成功后，安装源的唯一标示就是：CentOS-7_x86_64-1503，如果重复，系统会提示导入失败。

# 镜像存放目录，cobbler会将镜像中的所有安装文件拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS-7_x86_64-1503目录下。因此/var/www/cobbler目录必须具有足够容纳安装文件的空间。
