七、Cobbler安装操作系统

7.1 安装完系统后默认的密码是啥呢？

这个密码 $default_password_crypted 就是步骤3.6使用openssl passwd -1 生成的密码

 

grep rootpw /var/lib/cobbler/kickstarts/sample.ks

rootpw --iscrypted $default_password_crypted

7.2 PXE菜单文件

默认菜单文件内容

cat /tftpboot/pxelinux.cfg/default

DEFAULT menu

PROMPT 0

MENU TITLE Hexun Automation Install System

TIMEOUT 150

TOTALTIMEOUT 6000

ONTIMEOUT local

 

LABEL local

        MENU LABEL (local)

        MENU DEFAULT

        LOCALBOOT -1

 

LABEL centos5.8-x86_64

        kernel /images/centos5.8-x86_64/vmlinuz

        MENU LABEL centos5.8-x86_64

        append initrd=/images/centos5.8-x86_64/initrd.img ksdevice=bootif lang=  kssendmac text  ks=http://172.17.10.14/cblr/svc/op/

ks/profile/centos5.8-x86_64

        ipappend 2

指定系统的菜单文件内容

cat /tftpboot/pxelinux.cfg/01-00-19-b9-e5-34-fe

default linux

prompt 0

timeout 1

label linux

        kernel /images/centos5.8-x86_64/vmlinuz

        ipappend 2

        append initrd=/images/centos5.8-x86_64/initrd.img ksdevice=bootif lang=  kssendmac text  ks=http://172.17.10.14/cblr/svc/op/ks/system/host-188116

7.3 安装系统

将需要安装系统的服务器网卡启用PXE，启动服务器从PXE引导

默认从本地硬盘引导，可以修改，建议还是保持此默认。

 

选择安装系统centos5.8-x86_64即可自动安装系统

Tab键，可以对启动项参数进行编辑

 

安装源数据说明：

链接

https://url/cblr/links/centos5.8-x86_64/

目录

/var/www/cobbler/links/centos5.8-x86_64/

是一个链接目录，实际位置如下

ll links/

total 0

lrwxrwxrwx 1 root root 43 Mar 12 13:41 centos5.8-x86_64 -> /var/www/cobbler/ks_mirror/centos5.8-x86_64

7.4 使用Koan重装系统

koan是cobbler的一个辅助工具，koan是kickstart-over-a-network的缩写安装在客户端的使用，koan配合cobbler实现快速重装linux。

koan 在Fedora, Red Hat Enterprise Linux, 和 CentOS工作正常，其他Linux版本应该也不错

koan的相关脚本在此目录内/usr/lib/python2.4/site-packages/koan/

通过EPEL安装的koan版本为koan-2.2.3-2.el5，使用中报错较多，此版本比较稳定koan-1.6.6-1.el5，下载链接ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm

 

关于Koan更多内容见https://github.com/cobbler/cobbler/wiki/Koan

7.4.1 安装koan

在重装的机器上安装koan

rpm  -ivh koan-1.6.6-1.el5.noarch.rpm

- reboot to apply changes

注意：输入此命令重启后，不能再中止重装，重启后自动进入pxe装机。

reboot

执行reboot命令重启服务器后，客户端服务器会自动重新安装操作系统，无需人工干预

 

7.4.5 重新安装指定客户机系统

步骤3.11已经添加指定客户机配置，在这里使用配置为指定的服务器安装操作系统

 

[root@host-d-116 ~]# koan -r  --server=172.17.10.14  --system=host-188116

- reboot to apply changes

[root@host-d-116 ~]# reboot

系统重启看到kick1364390697与上面命令生成的相同，重装过程同上
