Ubuntu Server 12.04下Cobbler + DNSmasq +tftpd-hpa的安装配置

通过Cobbler 可以用来快速建立 Linux 网络安装环境。

一、安装cobbler软件

网络环境及安装计划
网关服务器：硬件路由，192.168.88.2
域名服务器：dnsmasq程序，192.168.88.253
DHCP服务器：dnsmasq 程序，192.168.88.253 动态地址范围192.168.88.100-254
tFTP服务器：tfpd-hpa程序，192.168.88.253
cobbler服务器：192.168.88.253

1. 安装cobbler和cobbler-web
其中cobbler-web，是cobbler的web接口，可以通过它来使cobbler操作形象。
# sudo apt-get install cobbler cobbler-web
建议把debmirror 和createrepo也一并安装好了。其中debmirror是用来建立Debinan系统镜像源的工具，而createrepo是用来建立RedHat系列镜像源的工具。
安装完成后，cobbler和apache的服务都会启动。
2. 检查安装cobbler结果
在这里我用curl小工具来测试
# 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就说明工作正常了。
3. 初步配置cobbler
3.1 检查配置是否正确
运行cobbler check检查配置
# 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.
根据上面的提示修复错误。
# sudo apt-get install debmirror
同时配置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
注释掉@dists和@arches两行
# vi /etc/debmirror.conf
...
#@dists="sid";
@sections="main,main/debian-installer,contrib,non-free";
#@arches="i386";
...
使配置生效
# sudo cobbler sync

*** TASK COMPLETE ***
重新检查配置
# sudo cobbler check           
No configuration problems found.  All systems go.
4.  配置cobbler web
安装好cobbler web后，默认的访问信息如下，
URL：http://<Chostname>/cobbler_web
用户名：cobbler
密码：cobbler
apache配置文件：/etc/apache2/conf.d/cobbler_web.conf
出于安全考虑，可以通过htdigest命令来修改用户cobbler的密码。
# 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
以后我们也可以随时通过cobbler sync来重新加载配置文件。
