[root@centos7 cobbler]#cobbler check  #检查环境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. #修改配置文件中server参数为自己的主机IP
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. #修改配置文件中next_server指向tftp服务器，这里我也指向自己的IP
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 #将selinux关闭
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp #将tftp服务启动
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. #执行cobbler get-loaders下载启动引导的文件
6 : enable and start rsyncd.service with systemctl #启动rsync服务
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories #安装支持deb包的组件，现在安装CentOS不需要此组件
8 : 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 #修改配置文件中password的参数为自己指定的安装完系统后的root密码
9 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them #fencing设备的配置Restart cobblerd and then run 'cobbler sync' to apply changes.
