Cobbler的安装方式和传统的方式相差无几，但是相对配置简单，提供WEB界面，不过相对运维工程师来讲，这个WEB反而不太实用。
我个人比较喜欢的是Cobbler可以在一套系统内定义多个系统和菜单，在大规模、多样化定制环境中非常实用。
如果只是单纯安装某一个操作系统，批量的，传统的就可以。
实际生产环境为了DHCP不冲突，这很重要，由于没有开启DHCP中继，所以放在一个新的VLAN即可。
实际在应用中，服务器是静态IP，即便服务器重启并从PXE启动也默认从local启动，所以影响不大。
Server： 192.168.1.110
GATEWAY：192.168.1.253
system：CentOS 6.6 minimal
注：我在centos6.7上安装此版本有问题，可能是BUG。
开始安装：
#配置yum源，使用epel安装，基本安装源没有cobbler
cd /etc/yum.repos.d/
yum install -y epel-release
[root@cobsrv yum.repos.d]# ls
CentOS-Base.repo CentOS-fasttrack.repo CentOS-Vault.repo epel-testing.repo
CentOS-Debuginfo.repo CentOS-Media.repo epel.repo
yum clean all
yum install -y cobbler cobbler-web pykickstart debmirror cman fence-agents
#pykickstart(检查kickstart语法错误)
service httpd start
chkconfig httpd on
service cobblerd start
/etc/init.d/iptables stop
chkconfig --level 35 iptables off
[root@cobsrv ~]# getenforce
Enforcing
vi /etc/selinux/config
#SELINUX=enforcing
SELINUX=disabled
reboot生效
cobbler check #报错，注意核对纠错
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 : change 'disable' to 'no' in /etc/xinetd.d/rsync
6 : comment out 'dists' on /etc/debmirror.conf for proper debian support
7 : comment out 'arches' on /etc/debmirror.conf for proper debian support
8 : 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
Restart cobblerd and then run 'cobbler sync' to apply changes.
#/etc/cobbler/settings中next_server和server修改为主机IP，默认127.0.0.1
next_server: 192.168.1.110
server: 192.168.1.110
#修改default_password_crypted默认密码，随机生成密码
openssl passwd -1 -salt `openssl rand -hex 4`
Password:
