六、yum仓库配置管理

6.1 首先导入系统镜像

参考步骤四、导入系统镜像，导入完毕后，进行下面的步骤

6.2 添加镜像

base、updates库使用163的repo源并增加EPEL库
base

cobbler repo add --name=centos5.8-x86_64-Base --mirror=http://mirrors.163.com/centos/5/os/x86_64/

将定义的仓库大写名字Base修改为小写base

cobbler repo edit --name=centos5.8-x86_64-base --mirror=http://mirrors.163.com/centos/5/os/x86_64/ --arch=x86_64 --breed=yum

updates

cobbler repo add --name=centos5.8-x86_64-updates --mirror=http://mirrors.163.com/centos/5/updates/x86_64/ --arch=x86_64 --breed=yum

添加EPEL仓库

cobbler repo add --name=centos5.8-x86_64-epel --mirror=http://mirrors.ustc.edu.cn/epel/5/x86_64/ --arch=x86_64 --breed=yum

6.3 同步yum仓库内容到本地

时间较长，注意磁盘容量是否满足。

cobbler reposync

task started: 2013-03-26_111553_reposync

task started (id=Reposync, time=Tue Mar 26 11:15:53 2013)

hello, reposync

run, reposync, run!

creating: /var/www/cobbler/repo_mirror/centos5.8-x86_64-updates/.origin/centos5.8-x86_64-updates.repo

running: /usr/bin/reposync -l -m -d --config=/var/www/cobbler/repo_mirror/centos5.8-x86_64-updates/.origin/centos5.8-x86_64-updates.repo --repoid=centos5.8-x86_64-updates --download_path=/var/www/cobbler/repo_mirror -a x86_64

………………略…………………………

received on stderr:

*** TASK COMPLETE ***

6.4 repo添加到profle，

安装系统时会自动添加仓库配置

cobbler profile edit --name=centos5.8-x86_64 --repos="centos5.8-x86_64-base centos5.8-x86_64-epel centos5.8-x86_64-updates" --distro=centos5.8-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos5u8-x64.cfg

6.4 删除仓库配置

cobbler repo remove --name=centos5.8-x86_64- updates

6.5 添加更新仓库源计划任务

cobbler reposync --tries=3 --no-fail

加入crontab 每周日更新一次即可

echo "0 2 * * 0 cobbler reposync --tries=3 --no-fail" >> /var/spool/cron/root

注意检查crond是否启动

/etc/init.d/crond status

crond is stopped

/etc/init.d/crond start

Starting crond: [ OK ]

chkconfig crond on

6.6 装机自动配置yum

如果你想安装系统时自动配置yum，请进行以下配置。

vim /etc/cobbler/settings

yum_post_install_mirror: 1

在装机脚本ks文件加入以下内容

%post

# Start yum configuration

$yum_config_stanza

# End yum configuration

下面的参数PXE安装系统是会引用你添加的cobbler repo配置
注意可能将系统、应用部署到较新版本，根据情况而配置

$yum_repo_stanza

这两个参数都来自Kickstart snippets，很值得研究https://github.com/cobbler/cobbler/wiki/Kickstart-snippets

系统安装自动配置的yum

cat /etc/yum.repos.d/cobbler-config.repo
