1.3 配置Cobbler

[root@localhost ~]# cobbler check

cp /etc/cobbler/settings{,.ori}                                                                                       #备份
sed -i 's/server: 127.0.0.1/server: 192.168.252.130/' /etc/cobbler/settings                                               #服务端IP
sed -i 's/next_server: 127.0.0.1/next_server: 192.168.252.130/' /etc/cobbler/settings                                     #服务端IP
sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings                                                         #dhcp只获取一次
sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings                                                     #cobbler只执行一遍
sed -ri "/default_password_crypted/s#(.*: ).*#\1\"`openssl passwd -1 -salt 'admin' '123456'`\"#" /etc/cobbler/settings  #设置密码为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                                                    #下载
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                                                          #写入磁盘
/etc/init.d/xinetd restart                                            #启动三个必须启动的服务。详情请看kickstart
/etc/init.d/cobblerd restart
/etc/init.d/httpd restart
cobbler sync       #    同步

挂载光盘：
[root@localhost ~]# mount /dev/cdrom /mnt/

制作镜像导入到 cobbler
[root@localhost ~]# cobbler import --path=/mnt/ --name=CentOS-6-x86_64 --arch=x86_64
--path= 路径
--name=名称
--arch=系统位数32 or 64

导入的位置
[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

查看镜像
[root@localhost /]# cobbler profile list
CentOS-6-x86_64

查看系统详细信息
[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 -

自定义kickstarts文件 
我们使用cobbler profile report命令看到Kickstart默认在/var/lib/cobbler/kickstarts/sample_end.ks 
我们直接使用命令进行修改，我们修改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
