自动化运维之cobbler批量部署操作系统（一）

注：本文只介绍cobbler简单的安装和使用，进阶操作以后有时间再进行整理。
cobbler装机系统是较早前kickstart的升级版，优点比较容易配置，还自带web界面比较易于管理，不过安装cobbler-web时提示如下：
Error: Package: cobbler-web-2.6.11-1.el6.noarch (epel)
Requires: Django >= 1.4
鉴于安装Django比较麻烦，我就没有使用cobbler-web的功能。

环境：centos6.4
IP：192.168.1.105
yum源：
CentOS 5 x86_64
rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
CentOS6 x86_64:
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
CentOS6 i386:
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm

步骤：
1.

<ol style="margin:0 1px 0 0px;padding-left:40px;" start="1" class="dp-css"><li>yum install cobbler httpd rsync tftp-server xinetd dhcp python-ctypes -y </li></ol>

<ol style="margin:0 1px 0 0px;padding-left:40px;" start="1" class="dp-css"><li>cobbler check       检验cobbler，根据提示一步步解决问题 </li></ol>

[root@bogon yum.repos.d]# cobbler check
httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:
Traceback (most recent call last):
File "/usr/lib/python2.6/site-packages/cobbler/cli.py", line 252, in check_setup

ProtocolError:

由第一行得知httpd没有启动，selinux没有关闭，所以照着提示做即可。
/etc/init.d/httpd restart && setenforce 0（或者直接更改配置文件）

然后再次运行cobbler check，提示如下：

除了第9.10.12这三个不用特别关注外，其他都需要修改，根据提示很简单。

3.
修改/etc/cobbler/dhcp.template ，根据实际情况配置即可，也不难。

4.
导入镜像
cobbler import --path=/media/CentOS_5.8_Final --name=CentOS5.8 --arch=x86_64
cobbler profile edit --name=centos5.4-i686-x86_64 --kickstart=kickstart路径
导入完成后使用
cobbler report查看一下
