概述
本文以Redhat6.5为基础，通过配置网络安装服务器，实现Redhat Linux的网络安装。主要用到的软件（服务）有DHCP,TFTP,NFS,Kickstart等。本文只列出具体步骤，不含原理说明。
1.基础配置
1.1更改IP地址
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=08:00:27:53:44:fb
TYPE=Ethernet
UUID=82affeef-922e-40b2-b89f-a5df8e9fa236
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.7.30
NETMASK=255.255.255.0
GATEWAY=192.168.7.1
IPV6INIT=no
USERCTL=no
[root@localhost ~]# ifup eth0
Active connection state: activated
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/1
1.2更改hostnme
[root@localhost ~]# vi /etc/sysconfig/network
[root@redhatnis ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=redhatnis
[root@localhost ~]# vi /etc/hosts
[root@localhost ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.7.30 redhatnis
1.3关闭SELINUX及防火墙（iptables）
[root@localhost ~]# vi /etc/selinux/config
[root@redhatnis ~]# cat /etc/selinux/config |grep disa
# d isabled - SELinux is fully disabled.
SELINUX=disabled
[root@localhost ~]# chkconfig |grep ipta
iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@localhost ~]# chkconfig --level 2345 iptables off
[root@localhost ~]# shutdown -ry 0
2.软件安装
2.1挂载安装光盘
[root@redhatnis ~]# mount /dev/sr0 /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@redhatnis ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_root-lv_root 20G 6.2G 12G 35% /
tmpfs 940M 72K 940M 1% /dev/shm
/dev/sda1 485M 39M 421M 9% /boot
/dev/sr0 3.6G 3.6G 0 100% /mnt
2.2配置YUM源
[root@redhatnis ~]# cd /etc/yum.repos.d
[root@redhatnis yum.repos.d]# vi installmedia.repo
[root@redhatnis yum.repos.d]# cat installmedia.repo
[InstallMedia]
name=Red Hat Enterprise Linux 6.5
baseurl=file:///mnt/Server
enabled=1
gpgcheck=0
[root@redhatnis yum.repos.d]# yum list
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

ConsoleKit.x86_64 0.4.1-3.el6 @anaconda-RedHatEnterpriseLinux-201311111358.x86_64/6.5
2.3安装所需软件
[root@redhatnis ~]# yum install -y -q xinetd tftp tftp-server ftp vsftpd dhcp nfs-utils
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
3.配置DHCP Server
[root@redhatnis ~]# cd /etc/dhcp
[root@redhatnis dhcp]# vi dhcpd.conf
[root@redhatnis dhcp]# cat dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
# see 'man 5 dhcpd.conf'
#
allow booting;
allow bootp;
#Boot 所需文件
