Ubuntu Server 12.04下cobbler + dnsmasq +tftpd-hpa的安裝配置（一）

經過Cobbler 能夠用來快速創建 Linux 網絡安裝環境。

1、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，能夠經過它來使cobbler操做形象。

# sudo apt-get install cobbler cobbler-web

建議把debmirror 和createrepo也一併安裝好了。其中debmirror是用來創建Debinan系統鏡像源的工具，而createrepo是用來創建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就說明工做正常了。

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

*** TASK COMPLETE ***

從新檢查配置

# sudo cobbler check            
No configuration problems found.  All systems go.

4.  配置cobbler web

安裝好cobbler web後，默認的訪問信息以下，

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，能夠經過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
New password:
Re-type new password:

使配置生效

之後咱們也能夠隨時經過cobbler sync來從新加載配置文件。
