1、配置YUM
vim /etc/yum.repos.d/rhel-debuginfo.repo
[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debug
baseurl=file:///misc/cd/Server
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
2、配置IP
vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0C:29:FC:E2:45
ONBOOT=yes
IPADDR=192.168.100.1
NETMASK=255.255.255.0
vim /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
HWADDR=12:34:56:78:90：ab
ONBOOT=yes
IPADDR=192.168.200.1
NETMASK=255.255.255.0
service network restart
3、安装、配置DHCP服务
yum install dhcp -y
cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
vim /etc/dhcpd.conf
＃全局配置
ddns-update-style none; #动态DNS更新方法
ignore client-updates; ＃忽略客户机更新
＃子网配置
#谁写IP谁傻X
subnet 192.168.100.0 netmask 255.255.255.0 {
＃分配IP地址池、子网掩码、网关、DNS
range dynamic-bootp 192.168.100.128 192.168.100.254;
option subnet-mask 255.255.255.0;
option routers 192.168.100.1;
option domain-name "benet.com";
option domain-name-servers 192.168.100.1,192.168.100.2;
#租约时间:最大时间，更新时间
default-lease-time 21600;
max-lease-time 43200;
＃主机配置（相当于WINDOWS里的保留）
host ns {
#next-server marvin.redhat.com;
#hardware ethernet 12:34:56:78:AB:CD;
#fixed-address 207.175.42.254;
}
subnet 192.168.200.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.200.128 192.168.200.254;
option subnet-mask 255.255.255.0;
option routers 192.168.200.1;
option domain-name "benet.com";
option domain-name-servers 192.168.200.1,192.168.200.2;
default-lease-time 21600;
max-lease-time 43200;
host ftp {
hardware ethernet 00:0C:29:60:E4:AD;
fixed-address 192.168.200.10;
}
host web {
hardware ethernet 12:34:56:78:90:AB;
fixed-address 192.168.200.20;
}
}
service dhcpd start
chkconfig dhcpd on
4、补充：
限制dhcp服务器提供服务的网络接口
vim /etc/sysconfig/dhcpd
DHCPDARGS="eth0 eth1"
租约文件
tail -f /var/lib/dhcpd/dhcpd.leases
