在 m01-61管理機上
[root@m01-61 ~]# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: nat filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@m01-61 ~]# getenforce
Disabled
[root@m01-61 ~]#
注意：
在虛擬機編輯---虛擬網絡編輯器----VM8---修改
虛擬機網卡採用NAT模式，不要使用橋接模式，因爲稍後我們會搭建DHCP服務器，在同一局域網多個DHCP服務會有衝突。
VMware的NAT模式的dhcp服務也關閉，避免干擾。
使用本地DHCP服務將IP地址分配給虛擬機（取消對勾）
安裝DHCP服務
yum install dhcp -y
修改配置文件
vim /etc/dhcp/dhcpd.conf
subnet 172.16.1.0 netmask 255.255.255.0 {
range 172.16.1.100 172.16.1.200;
option subnet-mask 255.255.255.0;
default-lease-time 21600;
max-lease-time 43200;
next-server 172.16.1.61;
filename "/pxelinux.0";
}
# 註釋
range 10.0.0.100 10.0.0.200; # 可分配的起始IP-結束IP
option subnet-mask 255.255.255.0; # 設定netmask
default-lease-time 21600; # 設置默認的IP租用期限
max-lease-time 43200; # 設置最大的IP租用期限
next-server 10.0.0.7; # 告知客戶端TFTP服務器的ip
filename "/pxelinux.0"; # 告知客戶端從TFTP根目錄下載pxelinux.0文件
/etc/init.d/dhcpd start
tailf /var/log/messages 如果沒有日誌
查看是否啓動此服務
/etc/init.d/rsyslog start
安裝TFTP服務：
yum -y install tftp-server
[root@m01-61 ~]# sed -i '14s#yes#no#' /etc/xinetd.d/tftp
[root@m01-61 ~]# cat /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
[root@m01-61 ~]#
[root@m01-61 ~]# /etc/init.d/xinetd restart
Stopping xinetd: [FAILED]
Starting xinetd: [ OK ]

udp 0 0 0.0.0.0:69 0.0.0.0:* 29427/xinetd
[root@m01-61 ~]#
安裝http服務：
yum -y install httpd
sed -i "277i ServerName 127.0.0.1:80" /etc/httpd/conf/httpd.conf
/etc/init.d/httpd start
設置虛擬機cd/dvd 啓用已連接和啓動時連接 使用ISO映像文件
mkdir /var/www/html/CentOS-6.8
mount /dev/cdrom /var/www/html/CentOS-6.8
http://10.0.0.61/CentOS-6.8/
yum -y install syslinux
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
cp -a /var/www/html/CentOS-6.8/isolinux/* /var/lib/tftpboot/
mkdir -p /var/lib/tftpboot/pxelinux.cfg
cp /var/www/html/CentOS-6.8/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
創建一個虛擬機
設置密碼
grub-crypt
123456
複製加密的密碼
rz ks_config20161108.tar.gz
tar xfP ks_config20161108.tar.gz
查看文件：
cd /var/www/html/ks_config/
修改文件
vim /var/lib/tftpboot/pxelinux.cfg/default
default ks
prompt 0
label ks
kernel vmlinuz
append initrd=initrd.img ks=http://172.16.1.61/ks_config/CentOS-6.8-ks.cfg ksdevice=eth1
記得需要wq！ 保存
############cobbler#######
用 su 使用root用戶
yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd
cobbler check
cp /etc/cobbler/settings{,.ori}
sed -i 's/server: 127.0.0.1/server: 172.16.1.101/' /etc/cobbler/settings

sed -i 's#yes#no#' /etc/xinetd.d/rsync
sed -i 's#yes#no#' /etc/xinetd.d/tftp
下載cobbler get-loaders
或者rz 包 cobbler_load.tar.gz
如果使用包的話就解壓tar xfP cobbler_load.tar.gz
