使用本地光盘安装 PXE kickstart （自动化无人值守批量安装服务器）
好久没搞这个东西了，最近马上又要用得到，复习一下
完整的步骤记在这里，说明以后再加上
环境 Centos 6.5 ESXI 虚拟机
服务器端 安装dhcp tftp-server nfs 挂载光盘
yum install dhcp -y
cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
修改vim /etc/init.d/dhcpd
vim /etc/dhcp/dhcpd.conf
# dhcpd.conf
# Sample configuration file for ISC dhcpd
# option definitions common to all supported networks...
# Use this to enble / disable dynamic dns updates globally.
#ddns-update-style none;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
#authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
# A slightly different configuration for an internal subnet.
subnet 192.167.1.0 netmask 255.255.255.0 {
range 192.167.1.122 192.167.1.129;
option domain-name-servers 202.106.0.20,192.167.1.104;
# option domain-name "internal.example.org";
option routers 192.167.1.1;
# option broadcast-address 10.5.5.31;
default-lease-time 600;
max-lease-time 7200;
next-server 192.167.1.121;
filename "pxelinux.0";
}报错 &解决办法
=====================================================
yum install tftp-server -y
vim /etc/xinetd.d/tftp
yum install syslinux -y
[root@ccda yum.repos.d]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
[root@ccda yum.repos.d]# cp /mnt/cdrom/isolinux/{vmlinuz,initrd.img} /var/lib/tftpboot/
[root@ccda yum.repos.d]# mkdir /var/lib/tftpboot/pxelinux.cfg
[root@ccda yum.repos.d]# cp /mnt/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
[root@ccda yum.repos.d]# chmod 644 /var/lib/tftpboot/pxelinux.cfg/default
[root@ccda yum.repos.d]# vim /var/lib/tftpboot/pxelinux.cfg/default
修改vim /var/lib/tftpboot/pxelinux.cfg/default
default linux #prompt 1 timeout 600 display boot.msg menu title Welcome to CentOS 6.5! label linux menu label ^Install or upgrade an existing system menu default kernel vmlinuz append initrd=initrd.img ks=nfs:192.167.1.121:/ks/ks.cfg label rescue menu label ^Rescue installed system kernel vmlinuz append initrd=initrd.img rescue
[root@ccda yum.repos.d]# service xinetd restart
[root@ccda yum.repos.d]# service iptables stop
[root@ccda yum.repos.d]# yum install system-config-kickstart -y
[root@ccda yum.repos.d]# mkdir /ks
[root@ccda ~]# service nfs start
[root@ccda ~]# chkconfig nfs on
[root@ccda ~]# umount /dev/cdrom
[root@ccda ~]# mount /dev/cdrom /media/
选择--> 保存文件到 /ks 目录 名称为ks.cfg
至此kickstart 安装完毕，如果需要减轻服务器压力 可将NFS单独装一台机器分离出去

====
%post---->%end 此处是安装完成执行的脚本 （要直接把脚本写在这里，不要先编辑脚本再用sh 命令执行脚本） 红色部分是配置yum源 蓝色部分是截取自动获取的IP写到网卡配置文件里，即把服务器改成固定IP （可以加上ntpdate命令同步时间）
备注：如果不确定需要安装的软件包 可以查看你其他机器上的 /root/anaconda-ks.cfg 文件中末尾@打头的报名复制到ks文件 @packages--->@end 之间
===============
至此客户端就可以开机自动安装系统了（保证客户机可以获取到dhcp地址）
一直在学习。。。。
