PXE无人值守安装

需要的软件包: httpd tftp tftp-server dhcp

1.将安装光盘复制到/var/www/html,确保可通过网络访问.

2.service xinetd start 启动守护进程

chkconfig xinetd on

3.vim /etc/xinetd.d/tftp

tftp配置文件记录了共享目录位置

server-args = -s /var/lib/tftpboot

启用tftp

disable = no

4. 将安装光盘中的isolinux目录中的所有文件复制到tftpboot.

5. yum install syslinux

find / -name "pxelinux.0"

一般的位置是: /usr/share/syslinux/pxelinux.0

6. pxelinux.0复制到 tftpboot 目录.

7. tftpboot 目录下创建 pxelinux.cfg 目录

8. cp isolinux.cfg pxelinux.0/default

复制isolinux.cfg文件到pxelinux.0下并改名为default

打开default文件. append 行后添加 ks=[服务器上kickstart文件路径]

注意:每一个label代表启动菜单的一项,添加kickstart路径到正确的位置.

[示例]

label linux

menu label ^Install or upgrade an existing system

menu default

kernel vmlinuz

append initrd=initrd.img ks=http://172.16.253.1/kickstart/ks.cfg

注意:kickstart文件放到在局域网内可访问的地址,如http目录下.并保证有访问权限.

不需要的label项可以删除.

9. 配置dhcp

/etc/dhcp/dhcpd.conf文件修改

全局参数添加:

allow booting;

allow bootp;

subnet子句添加:

next-server PXE服务器地址IP;

filename "pxelinux.0";

-----------------------------dhcp.conf配置文件示例---------------------------

## DHCP Server Configuration file.# see /usr/share/doc/dhcp*/dhcpd.conf.sample# see 'man 5 dhcpd.conf'#ddns-update-style none;default-lease-time 600;max-lease-time 7200;allow booting;allow bootp;option domain-name-servers 172.16.253.1;subnet 172.16.253.0 netmask 255.255.255.0 {range 172.16.253.100 172.16.253.200;option subnet-mask 255.255.255.0;option routers 172.16.253.1;next-server 172.16.253.1;filename "pxelinux.0";}

10. 制作kickstart文件

安装system-config-kickstart软件包生成kickstart文件.

生成的文件放到/var/www/html目录下并添加可读权限.
