说明：
Cobbler服务器系统：CentOS 5.10 64位
IP地址：192.168.21.128
需要安装部署的Linux系统：
eth0（第一块网卡，用于外网）IP地址段：192.168.21.160-192.168.21.200
eth1（第二块网卡，用于内网）IP地址段：10.0.0.160-10.0.0.200
子网掩码：255.255.255.0
网关：192.168.21.2
DNS：8.8.8.8 8.8.4.4
所有服务器均支持PXE网络启动
实现目的：通过配置Cobbler服务器，全自动批量安装部署Linux系统
具体操作：
第一部分：在Cobbler服务器上操作
一、关闭SELINUX
vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
setenforce 0 #使配置立即生效
二、配置防火墙，开启TCP：80端口、TCP：25151端口、UDP：69端口
vi /etc/sysconfig/iptables #编辑
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #http服务需要此端口
-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 69 -j ACCEPT #tftp服务需要此端口
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25151 -j ACCEPT #cobbler需要此端口
:wq! #保存退出
/etc/init.d/iptables restart #最后重启防火墙使配置生效
三、安装Cobbler
cd /usr/local/src
wget http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm #CentOS 5.x 64位
rpm -ivh epel-release-5-4.noarch.rpm
备注：
wget http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm #CentOS 5.x 32位
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm #CentOS6.x 64位
wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm #CentOS6.x 32位
yum install cobbler tftp tftp-server xinetd dhcp httpd rsync #安装cobbler
yum install pykickstart debmirror python-ctypes cman #安装运行cobbler需要的软件包
四、配置Cobbler
1、设置http服务
vi /etc/httpd/conf.d/wsgi.conf
LoadModule wsgi_module modules/mod_wsgi.so #取消前面的注释
:wq! #保存退出
chkconfig httpd on #设置开机启动
service httpd start #启动
2、设置tftp服务开机启动
vi /etc/cobbler/tftpd.template #编辑
service tftp
{
disable = no #修改为no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -B 1380 -v -s /tftpboot
per_source = 11
cps = 100 2
flags = IPv4
}
:wq! #保存退出
3、设置rsync服务开机启动
vi /etc/xinetd.d/rsync #编辑配置文件，设置开机启动rsync
service rsync
{
disable = no #修改为no
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
:wq! #保存退出
/etc/init.d/xinetd start #启动（CentOS中是以xinetd 来管理Rsync和tftp服务的）
4、配置cobbler相关参数
vi /etc/debmirror.conf #注释掉 @dists 和 @arches 两行
#@dists="sid";
#@arches="i386";
:wq! #保存退出
openssl passwd -1 -salt ‘osyunwei‘ ‘123456‘ #生成默认模板下系统安装完成之后root账号登录密码
$1$osyunwei$sEV8iwXXuR4CqzLXyLnzm0 #记录下这行，下面会用到
vi /etc/cobbler/settings #编辑，修改
default_password_crypted: "$1$osyunwei$sEV8iwXXuR4CqzLXyLnzm0"
next_server: 192.168.21.128
server: 192.168.21.128
manage_dhcp: 1
default_kickstart: /var/lib/cobbler/kickstarts/default.ks
:wq! #保存退出

5、配置dhcp服务器
vi /etc/cobbler/dhcp.template #编辑，修改
subnet 192.168.21.0 netmask 255.255.255.0 { #设置网段
option routers 192.168.21.2; #设置网关
option domain-name-servers 8.8.8.8,8.8.4.4; #设置dns服务器地址
option subnet-mask 255.255.255.0; #设置子网掩码
range dynamic-bootp 192.168.21.160 192.168.21.200; #设置dhcp服务器IP地址租用的范围
default-lease-time 21600; #默认租约时间
max-lease-time 43200; #最大租约时间
next-server $next_server;
class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
if option pxe-system-type = 00:02 {
filename "ia64/elilo.efi";
} else if option pxe-system-type = 00:06 {
filename "grub/grub-x86.efi";
} else if option pxe-system-type = 00:07 {
filename "grub/grub-x86_64.efi";
} else {
filename "pxelinux.0";
}
}
}
:wq! #保存退出
vi /etc/sysconfig/dhcpd #指定DHCP服务的网络接口
DHCPDARGS=eth0
:wq! #保存退出
dhcpd #测试dhcp服务器配置是否正确
chkconfig dhcpd on #设置开机启动
chkconfig cobblerd on #设置开机启动
cobbler get-loaders #安装cobbler相关工具包，否则检查cobbler配置会报错
service cobblerd start #启动cobbler
cobbler sync #同步配置文件到dhcp服务器
service dhcpd start #启动dhcp服务
6、设置cobbler相关服务启动脚本
vi /etc/rc.d/init.d/cobbler #编辑，添加以下代码
#!/bin/sh
# chkconfig: - 80 90
# description:cobbler
case $1 in
start)
/etc/init.d/httpd start
/etc/init.d/xinetd start
/etc/init.d/dhcpd start
/etc/init.d/cobblerd start
;;
stop)
/etc/init.d/httpd stop
/etc/init.d/xinetd stop
/etc/init.d/dhcpd stop
/etc/init.d/cobblerd stop
;;
restart)
/etc/init.d/httpd restart
/etc/init.d/xinetd restart
/etc/init.d/dhcpd restart
/etc/init.d/cobblerd restart
;;
status)
/etc/init.d/httpd status
/etc/init.d/xinetd status
/etc/init.d/dhcpd status
/etc/init.d/cobblerd status
;;
sync)
cobbler sync
;;
*)
echo "Input error,please in put ‘start|stop|restart|status|sync‘!";
exit 2>&1 >/dev/null &
;;
esac
:wq! #保存退出
chmod +x /etc/rc.d/init.d/cobbler #添加脚本执行权限
chkconfig cobbler on #添加开机启动
service cobbler restart #重启cobbler
cobbler check #检查cobbler配置，出现下面的提示，SELinux和防火墙前面已经设置过了，不用理会

=====================================================================================
The following are potential configuration items that you may want to fix:
1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
https://github.com/cobbler/cobbler/wiki/Selinux
2 : since iptables may be running, ensure 69, 80/443, and 25151 are unblocked
Restart cobblerd and then run ‘cobbler sync‘ to apply changes
=====================================================================================
五、挂载系统安装镜像到http服务器站点目录
上传系统安装镜像文件CentOS-5.10-x86_64-bin-DVD-1of2.iso到/usr/local/src/目录
mkdir -p /var/www/html/os/CentOS-5.10-x86_64 #创建挂载目录
mount -t iso9660 -o loop /usr/local/src/CentOS-5.10-x86_64-bin-DVD-1of2.iso /var/www/html/os/CentOS-5.10-x86_64 #挂载系统镜像
vi /etc/fstab #添加以下代码。实现开机自动挂载
/usr/local/src/CentOS-5.10-x86_64-bin-DVD-1of2.iso /var/www/html/os/CentOS-5.10-x86_64 iso9660 defaults,ro,loop 0 0
:wq! #保存退出
备注：iso9660使用df -T 查看设备 卸载：umount /var/www/html/os/CentOS-5.10-x86_64
重复上面的操作，把自己需要安装的CentOS系统镜像文件都挂载到/var/www/html/os/目录下
例如：
CentOS-5.10-x86_64-bin-DVD-1of2.iso
CentOS-6.5-x86_64-bin-DVD1.iso
六、创建kickstarts自动安装脚本
cd /var/lib/cobbler/kickstarts #进入默认Kickstart模板目录
vi /var/lib/cobbler/kickstarts/CentOS-5.10-x86_64.ks #创建CentOS-5.10-x86_64安装脚本
# Kickstart file automatically generated by anaconda.

:wq! #保存退出
七、导入系统镜像到cobbler
cobbler import --path=/var/www/html/os/CentOS-5.10-x86_64 --name=CentOS-5.10-x86_64 --arch=x86_64 #导入系统镜像文件，需要一段时间
cd /var/www/cobbler/ks_mirror #进入系统镜像导入目录
命令格式：cobbler import --path=镜像路径 -- name=安装引导名 --arch=32位或64位
重复上面的操作，把其他的系统镜像文件导入到cobbler
八、设置profile，按照操作系统版本分别关联系统镜像文件和kickstart自动安装文件
在第一次导入系统镜像时，cobbler会给安装镜像指定一个默认的kickstart自动安装文件
例如：CentOS-5.10-x86_64版本的kickstart自动安装文件为：/var/lib/cobbler/kickstarts/sample.ks
cobbler profile report --name CentOS-5.10-x86_64 #查看profile设置
cobbler distro report --name CentOS-5.10-x86_64 #查看安装镜像文件信息
cobbler profile remove --name=CentOS-5.10-x86_64 #移除profile
cobbler profile add --name=CentOS-5.10-x86_64 --distro=CentOS-5.10-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-5.10-x86_64.ks #添加
cobbler profile edit --name=CentOS-5.10-x86_64 --distro=CentOS-5.10-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-5.10-x86_64.ks #编辑
命令：cobbler profile add|edit|remove --name=安装引导名 --distro=系统镜像名 --kickstart=kickstart自动安装文件路径
--name：自定义的安装引导名，注意不能重复
--distro：系统安装镜像名，用cobbler distro list可以查看
--kickstart：与系统镜像文件相关联的kickstart自动安装文件
#查看Cobbler列表
cobbler list
cobbler report
cobbler profile report
cobbler distro list
#通过profile查找对应的kickstart自动安装文件文件
例如：
ksfile=$( cobbler profile report --name CentOS-5.10-x86_64|grep -E ‘^Kickstart‘ |head -n 1|cut -d ‘:‘ -f 2 );cat $ksfile;
重复上面的操作，把其他的系统镜像文件和kickstart自动安装文件关联起来
注意：
1、kickstart自动安装文件需要预先配置好
2、每次修改完配置文件，需要执行一次同步操作：cobbler sync 配置才能生效
3、kickstart自动安装文件可以用工具生成（需要用到图形界面操作）
yum install system-config-kickstart #安装
yum groupinstall "X Window System" #安装X Window图形界面
system-config-kickstart #运行kickstart配置
service cobbler sync #与cobbler sync作用相同
service cobbler restart #重启cobbler
第二部分：设置要安装的服务器从网络启动
开机之后，如下图所示，根据需要选择相应的系统版本进行安装，安装完成之后，系统会自动重启
系统运维 www.osyunwei.com 温馨提醒：qihang01原创内容©版权所有,转载请注明出处及原文链接
重新安装系统：
在需要重装系统的服务器上安装koan
wget http://dl.fedoraproject.org/pub/epel/5/x86_64/koan-2.4.0-1.el5.noarch.rpm #CentOS 5.X
rpm -ivh koan-2.4.0-1.el5.noarch.rpm #安装koan
http://dl.fedoraproject.org/pub/epel/6/x86_64/koan-2.4.0-1.el6.noarch.rpm #CentOS 6.X
yum install cobbler debmirror pykickstart python-ctypes cman #安装koan运行依赖包（需要设置epel源）
koan --list=profiles --server=192.168.21.128 #查看Cobbler服务器系统镜像列表
koan --replace-self --server=192.168.21.128 --profile=CentOS-5.10-x86_64 #选择要重装的系统
reboot #重新启动系统进行自动安装
扩展阅读：
Cobbler目录说明：
1、Cobbler配置文件目录：/etc/cobbler
/etc/cobbler/settings #cobbler主配置文件
/etc/cobbler/dhcp.template #DHCP服务的配置模板
/etc/cobbler/tftpd.template #tftp服务的配置模板
/etc/cobbler/rsync.template #rsync服务的配置模板
/etc/cobbler/iso #iso模板配置文件
/etc/cobbler/pxe #pxe模板文件
/etc/cobbler/power #电源的配置文件
/etc/cobbler/users.conf #Web服务授权配置文件
/etc/cobbler/users.digest #用于web访问的用户名密码配置文件
/etc/cobbler/dnsmasq.template #DNS服务的配置模板
/etc/cobbler/modules.conf #Cobbler模块配置文件
2、Cobbler数据目录：/var/lib/cobbler
/var/lib/cobbler/config #配置文件
/var/lib/cobbler/triggers #Cobbler命令
/var/lib/cobbler/kickstarts #默认存放kickstart文件
/var/lib/cobbler/loaders #存放的各种引导程序
3、系统安装镜像目录：/var/www/cobbler
/var/www/cobbler/ks_mirror #导入的系统镜像列表
/var/www/cobbler/images #导入的系统镜像启动文件
/var/www/cobbler/repo_mirror #yum源存储目录
4、日志目录：/var/log/cobbler
/var/log/cobbler/install.log #客户端系统安装日志
/var/log/cobbler/cobbler.log #cobbler日志
至此，Cobbler全自动批量安装部署Linux系统完成。
