cobbler深入学习

Posted 2020-08-08 shhnwangjian

• cobbler重要目录和cobbler各对象的关系

/var/www/cobbler/ks_mirror 存放操作系统镜像
/var/www/cobbler/repo_mirror 存放仓库镜像
/var/lib/cobbler/kickstarts 存放kickstarts文件
/var/lib/cobbler/loaders 存放启动时需要的文件
/var/lib/cobbler/snippets 存放脚本
/etc/cobbler 存放cobbler的配置文

 

• 自定义yum源

cobbler可以管理yum源，以使用阿里云的openstack为例

http://mirrors.aliyun.com/centos/7.2.1511/cloud/x86_64/openstack-mitaka/

1) 添加openstack仓库源

cobbler repo add --name=openstack-mitaka --mirror=http://mirrors.aliyun.com/centos/7.2.1511/cloud/x86_64/openstack-mitaka/ --arch=x86_64 --breed=yum

2) 同步 cobbler reposync

3) 将openstack-mitaka在安装centos 7时，默认导入安装

cobbler profile edit --name=CentOS-7.1-x86_64 --repos="openstack-mitaka"

cobbler profile report CentOS-7.1-x86_64 查看仓库源

vim /etc/cobbler/settings  可以查看到yum_post_install_mirror默认开启

4) 修改kickstart文件

vim /var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg

%end

%packages
@ base
@ core
sysstat
iptraf

ncurses-devel
openssl-devel
zlib-devel
OpenIPMI-tools

nmap

%end

%post
systemctl disable postfix.service

$yum_config_stanza
%end

5) 添加定时任务，定期同步repo

echo "1 3 * * * /usr/bin/cobbler reposync --tries=3 --no-fail" >> /var/spool/cron/root
