Oracle 使用PXE刷XD案例

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

[root@oracleplus ~]# more /etc/dhcpd.conf
subnet 192.168.30.0 netmask 255.255.255.0 {

  option broadcast-address 192.168.30.255;
  option routers 192.168.30.1;
  next-server 192.168.30.90;
  filename = "pxelinux.0";
}

}
tftp配置
[root@oracleplus ~]# more /etc/xinetd.d/tftp

}
nfs配置
[root@oracleplus ~]# more /etc/exports
/xd *(no_root_squash,no_subtree_check,insecure)
pxe配置
[root@oracleplus ~]# cp /usr/share/syslinux/pxelinux.0 /xd

上传preconf.csv到/xd目录
[root@oracleplus 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
