Cobbler 基础配置
cobbler配置,配置生效
cobbler sync
导入安装镜像
挂载光盘
mount -t iso9660 -o loop /tmp/CentOS-7-x86_64-DVD-1611.iso /mnt/
挂载Centos 6.8光盘镜像到/mnt目录下,导入
cobbler import --name=Centos-6.8 --path=/mnt/ --arch=x86_64
挂载Centos 7.3光盘镜像到/mnt目录下,导入
cobbler import --name=Centos-7.3 --path=/mnt/ --arch=x86_64
挂载ESXI 5.5光盘镜像到/mnt目录下,导入
cobbler import --path=/mnt/ --name=ESXI-5.5.0 --arch=x86_64
查看distro配置
cobbler distro report
定义自动安装的应答文件,文件放到/var/lib/cobbler/kickstarts/目录下
Cobbler通过读取该文件,执行相关安装步骤
请查看1.5 Cobbler 配置文件
为可用镜像配置默认ks文件
Centos 6.8
cobbler profile edit --name=Centos-6.8-x86_64 --kickstart=/var/lib/cobbler/kickstarts/Centos-6.8-x86_64.cfg
Centos 7.3
cobbler profile edit --name=Centos-7.3-x86_64 --kickstart=/var/lib/cobbler/kickstarts/Centos-7.3-x86_64.cfg
ESXI 5.5
cobbler profile edit --name=ESXI-5.5.0-x86_64 --kickstart=/var/lib/cobbler/kickstarts/esxi5.5.cfg
调整网卡内核参数(标准化,名称统一,关闭IPv6)
Centos 7.3
cobbler profile edit --name=Centos-7.3-x86_64 --kopts='net.ifnames=0 biosdevname=0 noipv6'
查看profile配置
cobbler profile report
建立本地yum源
Centos 6.8
cobbler repo add --name=Centos-6-x86_64 --mirror=https://mirrors.aliyun.com/centos/6.9/os/x86_64/ --arch=x86_64 --breed=yum --keep-update=Ycobbler repo add --name=Centos-6-epel-x86_64 --mirror=https://mirrors.aliyun.com/epel/6Server/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y
Centos 7.x
cobbler repo add --name=Centos-7-x86_64 --mirror=https://mirrors.aliyun.com/centos/7.4.1708/os/x86_64/ --arch=x86_64 --breed=yum --keep-update=Ycobbler repo add --name=Centos-7-epel-x86_64 --mirror=https://mirrors.aliyun.com/epel/7Server/x86_64/ --arch=x86_64 --breed=yum --keep-update=Ycobbler repo add --name=zabbix3.0-Centos7 --mirror=http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y
查看repo配置
cobbler repo report
执行同步任务
cobbler reposync
错误一例:
Exception occured: <class 'cobbler.cexceptions.CX'>
Exception value: 'cobbler reposync failed'
解决方法1: 把--breed=yum更换为rsync或wget
建立任务计划,每周六同步一次
echo "0 23 * * 6 /usr/bin/cobbler reposync >> /app/log/cobbler.log 2>&1" >> /var/spool/cron/root
重启Cron
Centos 6.8
/etc/init.d/crond restart
Centos 7.3
systemctl restart crond
为镜像配置本队YUM源
Centos 6.8
cobbler profile edit --name=Centos-6.8-x86_64 --repos="Centos-6-epel-x86_64 Centos-6.8-x86_64-extras Centos-6.8-x86_64-os Centos-6.8-x86_64-updates Centos-6.8-x86_64-cr Centos-6.8-x86_64-gfs zabbix3.0-Centos6"
Centos 7.3
cobbler profile edit --name=Centos-7.3-x86_64 --repos="Centos-7.3-x86_64-os Centos-7.3-x86_64-updates Centos-7.3-x86_64-extras Centos-7-epel-x86_64 Centos-7.3-x86_64-cloud-l Centos-7.3-x86_64-gfs zabbix3.0-Centos7"
根据MAC地址零交互安装
** 创建一个新的自定义安装**
cobbler system add --name=odb01.prod.ding --mac=00:0c:29:34:58:f1 --profile=Centos-6.8-x86_64 --ip-address=192.168.0.20 --subnet=255.255.255.0 --gateway=192.168.0.1 --interface=eth0 --static=1 --hostname=odb01.prod.ding --name-servers="114.114.114.114"
修改自定义安装(name不可修改)
cobbler system edit --name=odb01.prod.ding --mac=00:0c:29:34:58:f1 --profile=Centos-6.8-x86_64 --ip-address=192.168.0.20 --subnet=255.255.255.0 --gateway=192.168.0.1 --interface=eth0 --static=1 --hostname=odb01.prod.ding --name-servers="114.114.114.114"
查看system配置
cobbler system report
修改展示页面内容
[root@Centos-souce kickstarts# cat /etc/cobbler/pxe/pxedefault.template
DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | 系统自动化部署

TOTALTIMEOUT 6000

自动重装系统(注意:客户机配置)
问题:虽然可以重装系统,但是不能设置IP、DNS、主机名
解决:
- 重装时候,生成专门为这台机器使用的一次性系统profile,用完即删
- 将自定义操作交由saltstack或者ansible来做,但是IP地址怎么分配呢?
- 通过dell的IDRAC等远程管理卡的远程界面,手工PXE启动(个人推荐)
安装epel源,安装koan
yum install koan -y
获取Cobbler服务器上的可用系统列表
[root@openstack ~# koan --server=192.168.0.232 --list=profiles- looking for Cobbler at http://192.168.0.232:80/cobbler_apiCentos-7.3-x86_64
选择要重装的系统,执行安装命令
koan --replace-self --server=192.168.0.232 --profile=Centos-7.3-x886_64
