centos下dhcpv6+tftp pxe boot linux映像

创建dhcpv6服务器

1.安装dhcpd服务器 
    方法可以 yum 可以下载rpm再安装。（略）
2.dhcpd6配置
    检查 /proc/net目录是否存在 if_inet6 文件 .
   a. 有 : 证明系统已经具备为dhcpd6服务器设置ipv6地址的环境
   b. 无 : 
        先检查 /etc/modprobe/ipv6.conf 文件应该如下:

cat  /etc/modprobe.d/ipv6.conf

# Anaconda disabling ipv6
options ipv6 disable=0

        b1. 试加载 modprobe ipv6模块 加载不成功的话就看看是否要重新编译kernel加入ipv6的支持或独立编译ipv6.ko模块，不懂可以支centos.org
        b1如果没问题：

编辑 /etc/dhcp/dhcpd6.conf 如下
[root@Test nbi_img]# cat  /etc/dhcp/dhcpd6.conf

#
# DHCP for IPv6 Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd6.conf.sample
#   see 'man 5 dhcpd.conf'
#   run 'service dhcpd6 start' or 'dhcpd -6 -cf /etc/dhcp/dhcpd6.conf'
#
default-lease-time 2592000;
preferred-lifetime 604800;
option dhcp-renewal-time 3600;
option dhcp-rebinding-time 7200;
option dhcp6.domain-search "ztsystems.com";
option dhcp6.name-servers fddd:a:b:c::d:1;
#option dhcpd6.bootfile-url code 59 = string;
allow leasequery;
option dhcp6.info-refresh-time 21600;
option dhcp6.bootfile-url code 59 = string;
option dhcp6.client-arch-type code 61 = array of unsigned integer 16;
dhcpv6-lease-file-name "/var/lib/dhcpd/dhcpd6.leases";

subnet6 fddd:a:b:c::/64 {
    option dhcp6.bootfile-url "tftp://[fddd:a:b:c::d:1]/bootx64.efi";
    range6 fddd:a:b:c::d:3 fddd:a:b:c::d:ffff;
    range6 fddd:a:b:c:: temporary;
}

编辑对dhcpd6应网络界面 ipv6的地址自己定义，这里为fddd:a:b:c::d:1/64
[root@Test nbi_img]# cat  /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
IPADDR=192.168.5.1
PREFIX=24
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
DNS=127.0.0.1
IPV6INIT=yes
IPV6ADDR=fddd:a:b:c::d:1/64

service network restart 重启网络服务
service dhcpd6 start 启动dhcpd6服务

[root@Test nbi_img]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    inet 10.1.3.222/24 brd 10.1.3.255 scope global eth1
    inet6 fe80::d227:88ff:fef9:4879/64 scope link
       valid_lft forever preferred_lft forever

cat /var/log/message 无错误ip应该有了 (红色的)


TFTP服务器
安装 
yum install xinetd 或支centos下载 xinetd的rpm包

1.配置tftp 

tftp配置文件如下
[root@Test nbi_img]# cat /etc/xinetd.d/tftp

# default: off
# description: The tftp server serves files using the trivial file transfer \
#    protocol. The tftp protocol is often used to boot diskless \
#    workstations, download configuration files to network-aware printers, \
#    and to start the installation process for some operating systems.
service tftp
{
    socket_type        = dgram
    protocol           = udp
    wait               = yes
    user               = root
    server             = /usr/sbin/in.tftpd
    server_args        = -6 -s /tftpboot/
    disable            = no
    per_source         = 11
    cps                = 100 2
    flags              = IPv6
}

#    flags            = IPv6
#    flags            = IPv4

想知各项意思可以 man in.tftpd
/tftpboot 是tftpboot服务器的根目录。可自己定义
service xinetd start
cat /var/log/message 检查是否有错误
到centos.org下载  index of    /centos-6/6.4/os/x86_64/EFI/BOOT 下所有文件到 /tftpboot
