//通过cobbler check 核对当前设置是否有问题

[root@localhost ~]# cobbler check

The following are potential configuration items that you may want to fix:

1: reposync is not installed, install yum-utils or dnf-plugins-core

2: yumdownloader is not installed, install yum-utils or dnf-plugins-core

3: debmirror package is not installed, it will be required to manage debian deployments and repositories

4: 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.

#以上3、4是关于debian系统的错误，请忽略

解决方法：

1、yum install fence-agents

2、yum -y install yum-utils

3、执行cobbler get-loaders命令

4、wget -P /etc/yum.repos.d/ https://copr.fedoraproject.org/coprs/jkastner/dnf-plugins-core/repo/epel-7/jkastner-dnf-plugins-core-epel-7.repo && yum install dnf-plugins-core

//再次查看

[root@localhost ~]# cobbler check

#1、2忽略

//最后一个问题

[root@php kickstarts]# yum -y install debmirror

[root@php kickstarts]# sed -i ‘s/@dists=“sid”;/#@dists=“sid”;/’ /etc/debmirror.conf

[root@php kickstarts]# sed -i ‘s/@arches=“i386”;/#@arches=“i386”;/’ /etc/debmirror.conf

//检查就没有问题了

[root@php kickstarts]# cobbler check

No configuration problems found. All systems go.

//重启服务并同步配置，改完dhcp必须要sync同步配置

[root@localhost ~]# systemctl restart cobblerd
