安装cobbler，需要epel或者rpmforge源，若需要部署debian/ubuntu类系统，需要安装debmirror，需要epel源。到http://dl.fedoraproject.org/pub找适合自己系统的包。我的是centos6.2-x86_64所以安装下面这个epel源
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6Server/x86_64/epel-release-6-8.noarch.rpm
从下面地址找适合自己系统的debmirror包
http://rpmfind.net/linux/rpm2html/search.php?query=debmirror
安装cobbler与debmirror相关软件
yum install cobbler dhcp xinetd fence-agents pykickstart ed patch perl perl-Compress-Zlib perl-Digest-SHA perl-LockFile-Simple perl-libwww-perl
开始安装debmirror，
rpm -Uvh ftp://rpmfind.net/linux/epel/6/x86_64/debmirror-2.14-2.el6.noarch.rpm
修改/etc/debmirror.conf配置文件，注释掉@dists和@arches两行
vim /etc/debmirror.conf
#@dists="sid";
#@arches="i386";
开启cobbler服务并下载loaders
/etc/init.d/cobblerd restart && /etc/init.d/httpd restart && cobbler get-loaders
设置开机启动项
chkconfig xinetd on && chkconfig httpd on && chkconfig dhcpd on && chkconfig ip6tables off && chkconfig iptables off
修改cobbler配置
默认的，经过cobbler安装后的系统root密码是cobbler
如果不改，在cobbler check时会提示不安全。还是改一下把。假设预设root密码为admaster，则用openssl passwd -1 -salt转换可得到md5码加密的字串
openssl passwd -1 -salt 1 admaster
复制得到的字串后
vim /etc/cobbler/settings
全文搜索default_password_crypted后面的引号里粘上复制的那串
继续全文搜索127.0.0.1替换成相应服务器ip
若cblr和tftp是同一台机器的情况可以全文查找替换
:%s/127.0.0.1/192.168.44.249/g
如果不同则分别设置
设置cobbler server的IP地址
server: 192.168.44.249
设置PXE server的IP地址
next-server: 192.168.44.250
开启自动dhcp管理
manage_dhcp: 1
开启自动rsync管理
manage_rsync: 1
开启tftp和rsync
将两个服务配置文件的disable = yes改成no
sed -i '/disable/s/yes/no/g' /etc/xinetd.d/tftp && sed -i '/disable/s/yes/no/g' /etc/xinetd.d/rsync
配置dhcp模板
vim /etc/cobbler/dhcp.template
将网段、网关、路由写好保存退出
先重新加载一下cobbler的配置，再同步所有设置
/etc/init.d/cobblerd restart && cobbler sync
当执行cobbler sync时报如下错误
dhcpd -t failed
Exception occured: <class 'cobbler.cexceptions.CX'>
Exception value: 'cobbler trigger failed: cobbler.modules.sync_post_restart_services'
Exception Info:

raise CX("cobbler trigger failed: %s" % m.__name__)
!!! TASK FAILED !!!
是dhcp服务没起来的原因，查看/etc/dhcp/dhcpd.conf，可能是网段超出或者掩码不正确。具体问题可以执行tailf -100 /var/log/messages
导入系统iso
mkdir /cdrom
mount -o loop -t iso9660 ~/iso/CentOS-6.2-x86_64-bin-DVD1.iso /cdrom
cobbler import --path=/cdrom --name=CentOS-6.2 --arch=x86_64
umount -l /cdrom
mount -o loop -t iso9660 ~/iso/ubuntu-12.04.4-server-amd64.iso /cdrom
cobbler import --path=/cdrom --name=Ubuntu-12.04.4-Server --arch=x86_64
由于cobbler在导入initrd.gz的时候出错，所以手动把光盘netboot里面的复制过来覆盖。
cp /cdrom/install/netboot/ubuntu-installer/amd64/initrd.gz /var/lib/tftpboot/p_w_picpaths/Ubuntu-12.04.4-Server-x86_64
提示覆盖选y
配置kickstart文件
mkdir -p /var/www/ks/
编写centos6的ks.cfg
vim /var/www/ks/centos6.cfg
# centos6/ks.cfg
firewall --disabled

如需安装图形界面，在vim下面添加下面这三行

编写ubuntuserver12的ks文件
vim /var/www/ks/ubuntuserver12.cfg
#以下是阿谢的ks.cfg for ubuntu server 12

指定各系统所对应的ks文件位置
cobbler profile edit --name=CentOS-6.2-x86_64 --kickstart=/var/www/ks/centos6.cfg
cobbler profile edit --name=Ubuntu-12.04.4-Server-x86_64 --kickstart=/var/www/ks/ubuntuserver12.cfg
--name后面是/var/lib/cobbler/config/profiles.d目录里json文件名，如果提示错误就去看看json的名字到底是什么把name改成相应的即可
若需删除已导入系统安装源，先查看都有哪些安装源
cobbler list
选中一个不顺眼的直接remove profile和distro
cobbler profile remove --name=CentOS-6.2-i386
cobbler distro remove --name=CentOS-6.2-i386
验证是否已成功删除
cobbler profile find --distro=CentOS-6.2-i386
结果为空表示成功
注意CentOS-6.2 x86_64的dvd镜像在导入时候会被cobbler错误地识别成既有i386又有x86_64，所以不要删除i386的，否则x86_64也没了，我遇到过一次，可以把pxelinux.cfg/default这个启动菜单修改一下即可
修改pxe启动菜单default
vim /var/lib/tftpboot/pxelinux.cfg/default
TIMEOUT改成你希望的秒数x10，因为这个值的单位是100毫秒
TOTALTIMEOUT不知道干啥的
centos的append后写上ks=http://你kickstart服务器ip/cobbler/ks/配置文件名，这样写
append initrd=/p_w_picpaths/CentOS-6.2-x86_64/initrd.img ksdevice=eth0 lang= kssendmac text ks=http://192.168.44.249/cobbler/ks/centos6.cfg
ubuntu的append这样写
append initrd=/p_w_picpaths/Ubuntu-12.04.4-Server-x86_64/initrd.gz ksdevice=eth0 ks=http://192.168.44.249/cobbler/ks/ubuntuserver12.cfg
以上ksdevice表示从哪块网卡进行安装
关闭selinux
sed -i '/SELINUX/s/permissive/disabled/g' /etc/selinux/config && sed -i '/SELINUX/s/enforcing/disabled/g' /etc/selinux/config && setenforce 0
关闭iptables防火墙
/etc/init.d/iptables stop
打开dhcpd和xinetd
/etc/init.d/dhcpd restart && /etc/init.d/xinetd restart
检查cobbler是否已配置完毕并按照提示进行修正
cobbler check
出现以下提示
1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
2 : 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
3 : reposync is not installed, need for cobbler reposync, install/upgrade yum-utils?
4 : yumdownloader is not installed, needed for cobbler repo add with --rpm-list parameter, install/upgrade yum-utils?
5 : One or more repos need to be processed by cobbler reposync for the first time before kickstarting against them: Ubuntu-12.04.4-Server-x86_64
第一是提示如果需要安装debian/ubuntu系统，必须安装debmirror包
方法在前面有
第二点是因为没有修改默认root密码cobbler
第三、四、五点问题不大，可以忽略
客户端通过pxe网络启动
在引导菜单中选择需要安装的系统即可
若日后哪台服务器需要重装系统了，在这台服务器上需要安装koan工具，是依托rpmforge，先在这机器上安装rpmforge，去http://pkgs.repoforge.org/rpmforge-release/查看适合自己系统的包，比如我的是centos6.2-x86_64所以这样装
rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
安装好rpmforge后，安装koan
yum install koan
