1）安裝Cobbler所依賴的相關服務

[[email protected] ~]# yum -y install tftp tftp-server dhcp httpd  #pxe可通過http或者ftp等方式提供安裝檔案
[
 
[email protected] ~]# yum install -y syslinux  #提供pxe安裝所需要的pxelinux.0等檔案
[[email protected] ~]# vim /etc/dhcp/dhcpd.conf
    option domain-name "test.com";
    option domain-name-servers 8.8.8.8,114.114.114.114;
    default-lease-time 600;
    max-lease-time 7200;
    log-facility local7;
    subnet 192.168.4.0 netmask 255.255.255.0{  #ip地址範圍必須跟本機ip一致
            range 192.168.4.1 192.168.4.100;
            option routers 192.168.4.116;
            filename "pxelinux.0";
            next-server 192.168.4.116;
    }
[
 
[email protected] ~]# systemctl start dhcpd  #啟動dhcp
[[email protected] ~]# cat /var/lib/dhcpd/dhcpd.leases  #通過檢視該檔案可以看到ip的租借情況
[[email protected] ~]# systemctl start httpd tftp.socket  #啟動http，tftp

2）安裝cobbler

1、安裝cobbler，啟動服務，然後執行cobbler check

[[email protected] ~]# yum -y install cobbler
[[email protected] ~]# systemctl start cobblerd
[[email protected] ~]# cobbler check
    The following are potential configuration items that you may want to fix:
    
    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.
    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.
    3 : change 'disable' to 'no' in /etc/xinetd.d/tftp
    4 : 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.
    5 : enable and start rsyncd.service with systemctl
    6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
    7 : 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
    8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

    Restart cobblerd and then run 'cobbler sync' to apply changes.

2、針對檢查出來的各種報錯進行相應處理

#針對1、2、7進行修改
[[email protected] ~]# openssl passwd -1 -salt "123456" "zhanfei"  #建立金鑰
    $1$123456$KhkWS/sJLYBtZ7iKPSRxT0
[[email protected] ~]# vim /etc/cobbler/settings
　　...
    server: 192.168.4.116
    next_server: 192.168.4.116
    default_password_crypted: "$1$123456$KhkWS/sJLYBtZ7iKPSRxT0"  #此金鑰是安裝系統後root預設密碼
　　...
#針對3進行修改
[[email protected] ~]# vim /etc/xinetd.d/tftp
    ...
    disable = no
    ...
#針對4進行修改
[[email protected] ~]# cobbler get-loaders
...
#針對5進行修改
[[email protected] ~]# systemctl start rsyncd.service
[[email protected] ~]# systemctl disable rsyncd.service
...
#實驗不涉及debian系統，第6點可以不理會
#針對8進行修改
[[email protected] ~]# yum -y install fence-agents
...

3、重啟cobbler

[[email protected] ~]# systemctl restart cobblerd
[[email protected] ~]# cobbler check
    The following are potential configuration items that you may want to fix:

    1 : debmirror package is not installed, it will be required to manage debian deployments and repositories

    Restart cobblerd and then run 'cobbler sync' to apply changes.
[[email protected] ~]# cobbler sync  #忽略debian的配置

3）配置cobbler

1、建立centos7.2的cobbler物件

[[email protected] ~]# mount /dev/cdrom /mnt  #掛載centos7.2光碟機
[[email protected] ~]# cobbler import --name=centos-7.2-x86_6 --path=/mnt  #建立cobbler物件組，此過程較耗時
[[email protected] ~]# cobbler distro list  #檢視對應的distribution
    centos-7.2-x86_64

映象會被自動匯入到/var/www/cobbler/ks_mirror，後續通過http的方式獲取安裝源；

預設情況下，cobbler還會生成一個最小化安裝的kickstart檔案，預設是/var/lib/cobbler/kickstarts/sample_end.ks。如果我們想要自定義的kickstart檔案，可進行如下操作：

[[email protected] ~]# cp centos7.2.cfg /var/lib/cobbler/kickstarts/  #centos7.2.cfg為自定義的kickstart檔案
[[email protected] ~]# cobbler profile add --name=centos-7.2-x86_64-custom --distro=centos-7.2-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7.2.cfg  #--distro要對應上一步建立的distro物件
[[email protected] ~]# cobbler profile list
    centos-7.2-x86_64
    centos-7.2-x86_64-custom

檢查httpd和tftp服務相關目錄是否已經建立了相應的檔案：

[[email protected] ~]# ll /var/www/cobbler
total 0
drwxr-xr-x. 4 root root 54 Oct 17 16:06 images
drwxr-xr-x. 5 root root 67 Oct 17 16:04 ks_mirror
drwxr-xr-x. 2 root root 54 Oct 17 16:06 links
drwxr-xr-x. 2 root root  6 May 28 20:41 localmirror

drwxr-xr-x. 2 root root 62 Oct 17 10:29 svc
[[email protected] ~]# ll /var/lib/tftpboot/
total 300
drwxr-xr-x  3 root root     17 Oct 17 15:00 boot
drwxr-xr-x. 2 root root      6 May 28 20:41 etc
drwxr-xr-x. 2 root root     77 Oct 17 15:00 grub
drwxr-xr-x. 4 root root     54 Oct 17 16:06 images
drwxr-xr-x. 2 root root      6 May 28 20:41 images2
-rw-r--r--. 1 root root  26268 Mar  6  2015 memdisk
-rw-r--r--  2 root root  54964 May 10 16:49 menu.c32
drwxr-xr-x. 2 root root      6 May 28 20:41 ppc
-rw-r--r--  2 root root  16794 May 10 16:49 pxelinux.0
drwxr-xr-x. 2 root root     20 Oct 17 15:00 pxelinux.cfg
drwxr-xr-x. 2 root root     25 Oct 17 15:00 s390x
-rw-r--r--  2 root root 198236 May 10 16:49 yaboot

測試安裝：(只測試了cobbler自建的kickstart，成功)

2、建立centos6.5的cobbler物件

[[email protected] ~]# mount /dev/cdrom /mnt  #掛載centos7.2光碟機
[[email protected] ~]# cobbler import --name=centos-6.7-x86_64 --path=/mnt  #建立cobbler物件組
[[email protected] ~]# cobbler distro list  #檢視對應的distribution
    centos-6.7-x86_64
    centos-7.2-x86_64
[[email protected] ~]# cobbler profile list
    centos-6.7-x86_64
    centos-7.2-x86_64
    centos-7.2-x86_64-custom

測試安裝6.5：成功

4）cobbler的web管理介面

[[email protected] ~]# yum -y install cobbler-web
[[email protected] ~]# vim /etc/cobbler/modules.conf
    ...
    [authentication]
    module = authn_pam   #使用authn_pam，本地使用者認證模組
    ...
[[email protected] ~]# useradd cbadmin
[[email protected] ~]# echo 123456|passwd --stdin cbadmin
    ...
[[email protected] ~]# vim /etc/cobbler/users.conf
    ...
    [admins]
    admin = "cbadmin" 
[[email protected] ~]# systemctl restart cobblerd
