天萃荷净 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 {
  range dynamic-bootp 192.168.30.101 192.168.30.126;
  option broadcast-address 192.168.30.255;
  option routers 192.168.30.1;
  next-server 192.168.30.90;
  filename = "pxelinux.0";
}
--以下直接复制无需修改
ddns-update-style none;
subnet 10.182.77.0 netmask 255.255.255.0 {}
subnet 10.182.45.0 netmask 255.255.255.0 {
  range dynamic-bootp 10.182.45.92 10.182.45.100;
  option broadcast-address 10.182.45.255;
  option routers 10.182.45.1;
  next-server 10.182.77.133;
  filename = "pxelinux.0";
}

tftp配置

[root@oracleplus ~]# more /etc/xinetd.d/tftp
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -v -s /xd
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

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

[root@oracleplus pxelinux.cfg]# more /xd/pxelinux.cfg/default 
default linux
timeout 70

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
