1.3 配置Cobbler

[root@localhost ~]# cobbler check

cp /etc/cobbler/settings{,.ori}                                                                                       #備份
sed -i 's/server: 127.0.0.1/server: 192.168.252.130/' /etc/cobbler/settings                                               #服務端IP
sed -i 's/next_server: 127.0.0.1/next_server: 192.168.252.130/' /etc/cobbler/settings                                     #服務端IP
sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings                                                         #dhcp只獲取一次
sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings                                                     #cobbler只執行一遍
sed -ri "/default_password_crypted/s#(.*: ).*#\1\"`openssl passwd -1 -salt 'admin' '123456'`\"#" /etc/cobbler/settings  #設置密碼爲123456
sed -i 's#yes#no#' /etc/xinetd.d/rsync                                 #xinet 管理rsync
sed -i 's#yes#no#' /etc/xinetd.d/tftp                                  #xinet 管理tftp
cobbler get-loaders                                                    #下載
sed -i 's#192.168.1#192.168.252#g;22d;23d' /etc/cobbler/dhcp.template  # 修改dhcp配置文件
cobbler sync                                                          #寫入磁盤
/etc/init.d/xinetd restart                                            #啓動三個必須啓動的服務。詳情請看kickstart
/etc/init.d/cobblerd restart
/etc/init.d/httpd restart
cobbler sync       #    同步

掛載光盤：
[root@localhost ~]# mount /dev/cdrom /mnt/

製做鏡像導入到 cobbler
[root@localhost ~]# cobbler import --path=/mnt/ --name=CentOS-6-x86_64 --arch=x86_64
--path= 路徑
--name=名稱
--arch=系統位數32 or 64

導入的位置
[root@localhost ks_mirror]# pwd
/var/www/cobbler/ks_mirror
[root@localhost ks_mirror]# ls
CentOS-7-x86_64  config

查看 cobbler命令
        [root@localhost /]# cobbler profile
        usage
        =====
        cobbler profile add
        cobbler profile copy
        cobbler profile dumpvars
        cobbler profile edit
        cobbler profile find
        cobbler profile getks
        cobbler profile list
        cobbler profile remove
        cobbler profile rename
        cobbler profile report

查看鏡像
[root@localhost /]# cobbler profile list
CentOS-6-x86_64

查看系統詳細信息
[root@localhost /]# cobbler profile report

kickstarts文件放在/var/lib/cobbler/kickstarts下面

[root@localhost ~]# cd /var/lib/cobbler/kickstarts/
[root@localhost kickstarts]# rz -

自定義kickstarts文件 
咱們使用cobbler profile report命令看到Kickstart默認在/var/lib/cobbler/kickstarts/sample_end.ks 
咱們直接使用命令進行修改，咱們修改6的kickstarts

 [root@localhost /]# cobbler profile edit --name=CentOS-6-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-6-x86_64.cfg

同步配置
[root@localhost /]# cobbler sync
