centos6.5 pxe kickstart 批量部署

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

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

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。。。。
