Cobbler自定义yum源
再次了解下Cobbler的目录结构：
在/var/www/cobbler/ks_mirror目录下存放的是所有的镜像。
存放的是仓库镜像：
在/var/lib/cobbler/kickstarts目录下是存放的所有的kickstarts文件。
再有就是/etc/cobbler这个目录：
[root@vm1 loaders]# cd /etc/cobbler
[root@vm1 cobbler]# ll

我们再看下dhcp.template这个文件：
然后我们再看下settings这个文件：

在使用cobbler安装的虚拟机下面的文件/etc/yum.repos.d/cobbler-config.repo记录一个yum包的地址。
在源主机下其实有这个文件：
[root@vm1 config]# pwd
/var/www/cobbler/ks_mirror/config
[root@vm1 config]# cat centos7.9-x86_64.repo
[core-0]
name=core-0
baseurl=http://@@http_server@@/cobbler/ks_mirror/centos7.9-x86_64
enabled=1
gpgcheck=0
priority=$yum_distro_priority
添加库：
cobbler repo add --name=CentOS-7-x86_64-epel --mirror=https://mirrors.aliyun.com/epel/7Server/x86_64/ --arch=x86_64 --breed=yum然后再执行：
cobbler reposync这部分我执行不成功。我把这个命令记录在这个地方。
然后还需要Kickstart文件。
$yum_config_stanza
%end
5、添加定时任务，定期同步repo。
echo "1 3 * * * /usr/bincobbler reposync --tries=3 --no-fail" >> /var/spool/cron/rootLinux中，一切皆文件。对这句话，我们还要再理解。
例如：
[root@vm1 config]# cat /proc/loadavg
0.01 0.02 0.05 1/150 2662
[root@vm1 config]# lscpu
