使用PXE刷XD
需要安装服务
bind dhcp system-config-netboot tftp-server
dhcp配置
[root@xifenfei ~]# more /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 8)
[root@xifenfei ~]# more /etc/dhcpd.conf
subnet 192.168.30.0 netmask 255.255.255.0 {

}
nfs配置
[root@xifenfei ~]# more /etc/exports /xd *(no_root_squash,no_subtree_check,insecure)
pxe配置

上传preconf.csv到/xd目录
[root@xifenfei xd]# ll preconf.csv -rw-r--r-- 1 root root 2133 Mar 14 18:14 preconf.csv
然后重启dhcp,xinetd,nfs服务,重启需要恢复的xd的db and cell节点,验证结果如下
