文章摘要：CentOS 6.3 無人值守安裝過程 常見問題及解決方法

一、安裝過程kickstartDhcpTftpNfs

1.環境

Vmware Workstation 9.0

CentOS-6.3-i386-bin-DVD

技術交流Q群:298148856

2.安裝

[[email protected] ~]# rpm -qa |grep nfs-utils

nfs-utils-lib-1.1.5-4.el6.i686

nfs-utils-1.2.3-26.el6.i686

[[email protected] ~]#

[[email protected] ~]# rpm -qa |grep dhcp-devel

dhcp-devel-4.1.1-31.0.1.P1.el6.centos.1.i686

[[email protected] ~]#

如沒有進行安裝

yum install dhcp-devel nfs-utils xinetd tftp-server pykickstart syslinux

chkconfig --level 123456 dhcpd on

chkconfig --level 123456 tftp on

chkconfig --level 123456 nfs on

chkconfig --level 123456 xinetd on

chkconfig --level 123456 rpcbind on

mkdir /kickstart  /install

[[email protected] home]# vim /etc/dhcp/dhcpd.conf

#

# DHCP Server Configuration file.

#   see /usr/share/doc/dhcp*/dhcpd.conf.sample

#   see 'man 5 dhcpd.conf'

ignore client-updates;

allow booting;

allow bootp;

subnet 192.168.100.0 netmask 255.255.255.0 {

       option routers 192.168.100.1;

       option subnet-mask 255.255.255.0;

       default-lease-time 21600;

       max-lease-time 43200;

       range 192.168.100.128 192.168.100.140;

       filename "/kickstart/ks.cfg";

       next-server 192.168.100.1;

}

option space PXE;

class "PXE" {

       match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";

               option vendor-encapsulated-options 01:04:00:00:00:00:ff;

                       option boot-size 0x1;

                       filename "pxelinux.0";

                       option tftp-server-name "192.168.100.128";

}

[[email protected] home]# vim /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

{

disable = no

       socket_type             = dgram

       protocol                = udp

       wait                    = yes

       user                    = root

       server                  = /usr/sbin/in.tftpd

server_args             = -s /var/lib/tftpboot

       per_source              = 11

       cps                     = 100 2

       flags                   = IPv4

}

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot

cp /mnt/p_w_picpaths/pxeboot/initrd.img /var/lib/tftpboot

cp /mnt/p_w_picpaths/pxeboot/vmlinuz /var/lib/tftpboot

mkdir /var/lib/tftpboot /pxelinux.cfg

cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

将default檔案下面内容

label linux

 menu label ^Install or upgrade an existing system

 menu default

 kernel vmlinuz

 append initrd=initrd.img

修改成

label linux

 kernel vmlinuz

 append ksdevice=eth0 load_ramdisk=1 initrd=initrd.img network ks=nfs:192.168.100.128:/kickstart/ks.cfg noipv6

3.自定義root密碼

[[email protected] ~]# perl -e 'print crypt("jngd!!!!!!",q($1$BYSimLw0)),"\n"' $1$BYSimLw0$9zfbFAPUuuXM8K/iLaSec1 [[email protected] ~]# ……………………………… url --url="http://192.168.100.128/centOS6" rootpw --iscrypted $1$BYSimLw0$9zfbFAPUuuXM8K/iLaSec1 auth  --useshadow  --passalgo=sha512 ……………………………………

二、常見問題及解決方法

1.出現TFTP PXE-T01: File not found PXE-E3B: TFTP Error –File

在用戶端啟動時出現下面問題

解決方法:

原因為tftp工作目錄在/var/lib/tftp ,配置時按照網上文檔配置到了/tftpboot,是以出現以上錯誤

檢視tftp 工作目錄，下面紅色字型

[[email protected] tftpboot]# cat /etc/xinetd.d/tftp

service tftp

{

        disable    = no

        socket_type            = dgram

        protocol           = udp

        wait                   = yes

        user                            = root

        server                        = /usr/sbin/in.tftpd
