[root@cobbler-server ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
2.4 检查cobbler配置
[root@cobbler-server ~]# cobbler check
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 : enable and start rsyncd.service with systemctl
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : 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
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.

2.10 检查cobbler组件服务是否启动
[root@cobbler-server ~]# systemctl list-unit-files | egrep "cobblerd|\bdhcpd\b|httpd|xinetd"
cobblerd.service enabled
dhcpd.service enabled
httpd.service enabled
xinetd.service enabled
3 cobbler命令行配置管理
3.1 导入系统镜像
#挂载光盘镜像到/mnt目录下
[root@cobbler-server ~]# mount /dev/sr0 /mnt
mount: /dev/sr0 is write-protected, mounting read-only
[root@cobbler-server ~]# cd /mnt/
[root@cobbler-server mnt]# ls
CentOS_BuildTag EULA images LiveOS repodata RPM-GPG-KEY-CentOS-Testing-7
EFI GPL isolinux Packages RPM-GPG-KEY-CentOS-7 TRANS.TBL
#运行cobbler import导入系统镜像
[root@cobbler-server mnt]# cobbler import --name=CentOS-7-x86_64 --arch=x86_64 --path=/mnt
#列出导入的发行版镜像
[root@cobbler-server mnt]# cobbler distro list
CentOS-7-x86_64
#列出导入的配置文件
[root@cobbler-server mnt]# cobbler profile list
CentOS-7-x86_64
#导入系统镜像存放目录位置
[root@cobbler-server mnt]# cd /var/www/cobbler/ks_mirror/
[root@cobbler-server ks_mirror]# ls
