三、配置Cobbler

  1. [root@linux-node1 ~]# /etc/init.d/httpd restart
  2. 停止 httpd：                                               [失败]
  3. 正在启动 httpd：                                           [确定]
  4. [root@linux-node1 ~]# /etc/init.d/cobblerd start
  5. Starting cobbler daemon:                                   [确定]
  6. [root@linux-node1 ~]# cobbler check  # 检查Cobbler的配置，如果看不到下面的结果，再次执行/etc/init.d/cobblerd restart
  7. The following are potential configuration items that you may want to fix:
  8. 
  9. 1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
  10. 2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
  11. 3 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.  Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
  12. 4 : change 'disable' to 'no' in /etc/xinetd.d/rsync
  13. 5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
  14. 6 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
  15. 7 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
  16. 
  17. Restart cobblerd and then run 'cobbler sync' to apply changes.
  18. 
  19. # 看着上面的结果，一个一个解决。
  20. # 第1、2、6个问题，顺便修改其他功能
  21. [root@linux-node1 ~]# cp /etc/cobbler/settings{,.ori}  # 备份
  22. 
  23. # server，Cobbler服务器的IP。
  24. sed -i 's/server: 127.0.0.1/server: 10.0.0.7/' /etc/cobbler/settings
  25. 
  26. # next_server，如果用Cobbler管理DHCP，修改本项，作用不解释，看kickstart。
  27. sed -i 's/next_server: 127.0.0.1/next_server: 10.0.0.7/' /etc/cobbler/settings
  28. 
  29. # 用Cobbler管理DHCP
  30. sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings
  31. 
  32. # 防止循环装系统，适用于服务器第一启动项是PXE启动。
  33. sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings
  34. 
  35. # 设置新装系统的默认root密码123456。下面的命令来源于提示6。random-phrase-here为干扰码，可以自行设定。
  36. [root@linux-node1 ~]# openssl passwd -1 -salt 'oldboy' '123456'
  37. $1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1
  38. [root@linux-node1 ~]# vim /etc/cobbler/settings 
  39. default_password_crypted: "$1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1" 
  40. 
  41. # 第3个问题
  42. [root@linux-node1 ~]# cobbler get-loaders  # 会自动从官网下载
  43. [root@linux-node1 ~]# cd /var/lib/cobbler/loaders/  # 下载的内容
  44. [root@linux-node1 loaders]# ls
  45. COPYING.elilo     COPYING.yaboot  grub-x86_64.efi  menu.c32    README
  46. COPYING.syslinux  elilo-ia64.efi  grub-x86.efi     pxelinux.0  yaboot
  47. 
  48. # 第4个问题
  49. [root@linux-node1 ~]# vim /etc/xinetd.d/rsync
  50. disable = no
  51. [root@linux-node1 ~]# /etc/init.d/xinetd restart
  52. 停止 xinetd：                                              [确定]
  53. 正在启动 xinetd：                                          [确定]
  54. 
  55. [root@linux-node1 ~]# /etc/init.d/cobblerd restart
  56. Stopping cobbler daemon:                                   [确定]

  58. [root@linux-node1 ~]# cobbler check
  59. The following are potential configuration items that you may want to fix:
  60. 
  61. 1 : debmirror package is not installed, it will be required to manage debian deployments and repositories  # 和debian系统相关，不需要
  62. 2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them # fence设备相关，不需要
  63. Restart cobblerd and then run 'cobbler sync' to apply changes.

  1. 配置DHCP
  1. # 修改cobbler的dhcp模版，不要直接修改dhcp本身的配置文件，因为cobbler会覆盖。
  2. 
  3. [root@linux-node1 ~]# vim /etc/cobbler/dhcp.template 
  4. # 仅列出修改过的字段
  5. ……
  6. subnet 10.0.0.0 netmask 255.255.255.0 {
  7.      option routers             10.0.0.2;
  8.      option domain-name-servers 10.0.0.2;
  9.      option subnet-mask         255.255.255.0;
  10.      range dynamic-bootp        10.0.0.100 10.0.0.200;
  11. ……
5、同步cobbler配置
  1. # 同步最新cobbler配置，它会根据配置自动修改dhcp等服务。
  2. [root@linux-node1 ~]# cobbler sync   # 同步所有配置，可以仔细看一下sync做了什么。
  3. task started: 2015-12-03_204822_sync

定制化安装
指定某台服务器使用指定ks文件
分一台服务器的最简单的方法就是物理MAC地址。
物理服务器的MAC地址在服务器上的标签上写了。
虚拟机的MAC查看

cobbler system add --name=oldboy --mac=00:0C:29:30:07:75--profile=CentOS-7.1-x86_64 --ip-address=10.0.0.100--subnet=255.255.255.0 --gateway=10.0.0.100 --interface=eth0 --static=1 --hostname=oldboy.example.com --name-servers="114.114.114.114 8.8.8.8"
#--name 自定义，但不能重复
#查看定义的列表
[root@linux-node1 ~]# cobbler system list
Wbe01 （主机名）
[root@linux-node1 ~]# cobbler sync
下次在开机或重启就会自动安装了
Cobbler的Web管理界面的安装与配置
已经安装cobbler-web软件的环境下。
访问网址：http://10.0.0.100/cobbler_web和https://10.0.0.100/cobbler_web
默认用户名：cobbler
默认密码 ：cobbler
/etc/cobbler/users.conf       # Web服务授权配置文件
/etc/cobbler/users.digest     # 用于web访问的用户名密码配置文件
[root@linux-node1 ~]# cat /etc/cobbler/users.digest
cobbler:Cobbler:a2d6bae81669d707b72c0bd9806e01f3
#设置Cobbler web用户登陆密码
#在Cobbler组添加cobbler用户，提示输入2遍密码确认
[root@linux-node1 ~]# htdigest /etc/cobbler/users.digest "Cobbler" cobbler
Changing password for user cobbler in realm Cobbler
New password: 123456
Re-type new password:123456
[root@linux-node1 ~]# cobbler sync
[root@linux-node1 ~]# /etc/init.d/httpd restart
停止 httpd：                                               [确定]
正在启动 httpd：                                           [确定]
[root@linux-node1 ~]# /etc/init.d/cobblerd restart
Stopping cobbler daemon:                                   [确定]
Starting cobbler daemon:                                   [确定]
以后就需要用123456这个密码登录了。
温馨提示：安装的系统内存要2G以上哦
