七.使用cobbler批量安装系统

一.cobbler_web页面无法访问

安装cobbler_web组件后访问web页面，URL:https://192.168.28.90/cobbler_web
页面报错信息如下：
Internal Server Error

Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

查询最新的ssl报错日志如下：

查看cobbler_web配置文件
[root@cobbler ~]# vim /usr/share/cobbler/web/settings.py
 38 if django.VERSION[0] == 1 and django.VERSION[1] < 4:
 39     ADMIN_MEDIA_PREFIX = '/media/'
 40 else:
 41     STATIC_URL = '/media/'
 89 from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS
[root@cobbler ~]# sed -n '38,41p' /usr/share/cobbler/web/settings.py
if django.VERSION[0] == 1 and django.VERSION[1] < 4:
    ADMIN_MEDIA_PREFIX = '/media/'
else:
    STATIC_URL = '/media/'

[root@cobbler ~]#  sed -n '89p' /usr/share/cobbler/web/settings.py
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS

#初步判断应该是pythone-django版本问题
解决办法：
#下载pip.py
[root@cobbler ~]# cd /home/downloads/
[root@cobbler downloads]# wget https://bootstrap.pypa.io/get-pip.py
#调用本地python运行pip.py脚本
[root@cobbler downloads]# python get-pip.py

问题解决！！！！！

设置cobbler登录用户名密码

cobbler的web操作页面初始账号密码都是cobbler
#为已存在的用户重置密码：
htdigest /etc/cobbler/users.digest "Cobbler" cobbler
#添加新用户：
htdigest /etc/cobbler/users.digest "Cobbler" yourname
[root@cobbler ~]# htdigest /etc/cobbler/users.digest "Cobbler" hexu
Adding user hexu in realm Cobbler
New password: 
Re-type new password: 

二.cobbler命令相关操作

cobbler check    核对当前设置是否有问题
cobbler list     列出所有的cobbler元素
cobbler report   列出元素的详细信息
cobbler sync     同步配置到数据目录,更改配置最好都要执行下
cobbler reposync 同步yum仓库
cobbler distro   查看导入的发行版系统信息
cobbler system   查看添加的系统信息
cobbler profile  查看配置信息

三、RPM仓库管理

相关阅读：https://fedorahosted.org/cobbler/wiki/ManageYumRepos

我们可以为cobbler添加RPM仓库：
cobbler repo add --name=CentOS-5-i386 --mirror=http://mirrors.163.com/centos/5/os/i386/
cobbler repo add --name=EPEL-5-i386 --mirror=http://download.fedoraproject.org/pub/epel/5/i386/

同步仓库到本地：
cobbler reposync

也可以通过设置--mirror-locally=0不下载到本地，而通过kickstart server去仓库下载rpm包。

添加计划任务，每天凌晨两点进行一次同步：
crontab -e
0 2 * * * cobbler reposync --tries=3 --no-fail
