6、yum倉庫配置管理

6.1 首先導入系統鏡像

參考步驟4、導入系統鏡像，導入完畢後，進行下面的步驟

6.2 添加鏡像

base、updates庫使用163的repo源並增長EPEL庫

base

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

將定義的倉庫大寫名字Base修改成小寫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倉庫

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倉庫內容到本地

時間較長，注意磁盤容量是否知足。

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…………………………

*** TASK COMPLETE ***

6.4 repo添加到profle，

安裝系統時會自動添加倉庫配置

 

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 刪除倉庫配置

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

6.5 添加更新倉庫源計劃任務

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

 

加入crontab 每週日更新一次便可

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

 

注意檢查crond是否啓動

/etc/init.d/crond status

crond is stopped

/etc/init.d/crond start

Starting crond:                                            [  OK  ]

chkconfig crond on  

6.6 裝機自動配置yum

若是你想安裝系統時自動配置yum，請進行如下配置。

vim /etc/cobbler/settings

yum_post_install_mirror: 1

在裝機腳本ks文件加入如下內容

%post

# Start yum configuration

$yum_config_stanza

# End yum configuration

 

下面的參數PXE安裝系統是會引用你添加的cobbler repo配置

注意可能將系統、應用部署到較新版本，根據狀況而配置

$yum_repo_stanza

這兩個參數都來自Kickstart snippets，很值得研究https://github.com/cobbler/cobbler/wiki/Kickstart-snippets

 

系統安裝自動配置的yum

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

[core-0]

name=core-0

baseurl=http://172.17.10.14/cobbler/ks_mirror/centos5.8-x86_64
