通過Cobbler 可以用來快速建立 Linux 網絡安裝環境。
一、安裝cobbler軟件
網絡環境及安裝計劃
網關服務器：硬件路由，192.168.88.2
域名服務器：dnsmasq程序，192.168.88.253
DHCP服務器：dnsmasq 程序，192.168.88.253 動態地址範圍192.168.88.100-254
tFTP服務器：tfpd-hpa程序，192.168.88.253
cobbler服務器：192.168.88.253
1. 安裝cobbler和cobbler-web
其中cobbler-web，是cobbler的web接口，可以通過它來使cobbler操作形象。
# sudo apt-get install cobbler cobbler-web
建議把debmirror 和createrepo也一併安裝好了。其中debmirror是用來建立Debinan系統鏡像源的工具，而createrepo是用來建立RedHat系列鏡像源的工具。
安裝完成後，cobbler和apache的服務都會啓動。
2. 檢查安裝cobbler結果
在這裏我用curl小工具來測試
# curl -I 192.168.88.253/cobbler/
HTTP/1.1 200 OK
Date: Fri, 01 Nov 2013 19:24:07 GMT
Server: Apache/2.2.22 (Ubuntu)
Vary: Accept-Encoding
Content-Type: text/html;charset=UTF-8
返回200OK就說明工作正常了。
3. 初步配置cobbler
3.1 檢查配置是否正確
運行cobbler check檢查配置
# sudo cobbler check
The following are potential configuration items that you may want to fix:
1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
Restart cobblerd and then run 'cobbler sync' to apply changes.
根據上面的提示修復錯誤。
# sudo apt-get install debmirror
同時配置debmirror
生成/etc/debmirror.conf配置文件
# cp /usr/share/doc/debmirror/examples/debmirror.conf /etc/
修改/etc/debmirror.conf配置文件
註釋掉@dists和@arches兩行
# vi /etc/debmirror.conf
...
#@dists="sid";
@sections="main,main/debian-installer,contrib,non-free";
#@arches="i386";
...
使配置生效
# sudo cobbler sync

重新檢查配置
# sudo cobbler check
No configuration problems found. All systems go.
4. 配置cobbler web
安裝好cobbler web後，默認的訪問信息如下，
URL：http://<Chostname>/cobbler_web
用戶名：cobbler
密碼：cobbler
apache配置文件：/etc/apache2/conf.d/cobbler_web.conf
出於安全考慮，可以通過htdigest命令來修改用戶cobbler的密碼。
# htdigest /etc/cobbler/users.digest "Cobbler" cobbler
Changing password for user cobbler in realm Cobbler

使配置生效
以後我們也可以隨時通過cobbler sync來重新加載配置文件。
