cobbler配置
Cobbler无人值守安装CentOS
原始系统：
Centos6.3-x86_64-minimal版本
系统更新后是centos6.7
1、更新系统
2、安装cobbler所需要的服务
3、配置epelyum源，使用阿里云yum源。
4、安装cobbler
5、关闭防火墙和selinux
临时关闭selinux
永久关闭可修改Selinux配置文件
6、启动cobbler
7、启动httpd服务
但是没有提示启动成功，这里需要修改配置文件，/etc/httpd/conf/httpd.conf，
添加ServerName80，打开端口，再重启ok。
8、检查cobbler配置，cobblercheck
出现报错，别急，需要重启cobbler就可以
重启后出现一堆提示：
[root@localhost~]#cobblercheck
Thefollowingarepotentialconfigurationitemsthatyoumaywanttofix:
1:
The'server'fieldin/etc/cobbler/settingsmustbesettosomethingotherthanlocalhost,orkickstartingfeatureswillnotwork.ThisshouldbearesolvablehostnameorIPforthebootserverasreachablebyallmachinesthatwilluseit.
编辑/etc/cobbler/setting文件，找到server选项，将ip127.0.0.1修改成本地ip。
2:

编辑/etc/cobbler/setting文件，找到next_server选项，将ip127.0.0.1修改成本地ip.
3:

编辑/etc/xinetd.d/tftp，将disable=yes改成no

经过网上查找，这个cobbler的一个bug，需要执行命令：
5:
change'disable'to'no'in/etc/xinetd.d/rsync
编辑/etc/xinetd.d/rsync文件，将disable=yes改成no
6:
debmirrorpackageisnotinstalled,itwillberequiredtomanagedebiandeploymentsandrepositories
这个提示不用管，因为不用debian系统。
如用到debian，需要安装debmirror包
7:
ksvalidatorwasnotfound,installpykickstart
需要安装pykickstart
8:
Thedefaultpasswordusedbythesampletemplatesfornewlyinstalledmachines（default_password_cryptedin/etc/cobbler/settings）isstillsetto'cobbler'andshouldbechanged,try:
"opensslpasswd-1-salt'random-phrase-here''your-password-here'"togeneratenewone
修改cobbler用户的默认密码，其中“random-phrase-here”为干扰码
使用生成后的密码替换/etc/cobbler/settings中的密码
9:
fencingtoolswerenotfound,andarerequiredtousethe（optional）powermanagementfeatures.installcmanorfence-agentstousethem
安装fence-agents
Restartcobblerdandthenrun'cobblersync'toapplychanges.
重启cobblerd
执行命令：
cobblersync，让配置同步生效
9、挂载镜像
新建/iso目录用来放镜像
由于是虚拟机中实验，利用Xftp工具将镜像上传到/iso目录中。
给镜像755的权限
将镜像挂载到/mnt目录中
10、导入镜像
Cobbler会把要安装的iso镜像导入到源安装目录/var/www/cobbler/ks_mirror中。
命令说明：
cobblerimport--path=/mnt--name=CentOS5.8--arch=x86_64
可mancobbler查看import的配置说明
--path：
挂载点
--name：
给安装源定义名字，安装源名字唯一，不能重复
--arch：
指定安装源是32位还是64位，目前支持的选项有:
x86│x86_64│ia64
查看导入的安装源列表：
11、配置dhcp服务
1、修改cobbler配置，让cobbler来管理dhcp服务，编辑文件/etc/cobbler/settings
将manage_dhcp：
0修改为1。
2、编辑/etc/cobbler/dhcp.template，此文件是cobbler管理dhcp的模板，
Ip地址根据自己环境来设定。
3、重启xinetd
4、同步cobbler配置
