配置DHCP服务器
给服务器配置了IP地址
[root@L-server ~]# uname -a
Linux L-server 2.6.32 #2 SMP Sat Sep 13 14:48:15 CST 2014 x86_64 x86_64 x86_64 GNU/Linux

查看了下dhcp软件包，没有安装
[root@L-server ~]#
[root@L-server ~]# rpm -q dhcp
package dhcp is not installed
[root@L-server ~]#
先配下yum库吧，方便以后实验用
[root@L-server ~]# rpm -q dhcp
package dhcp is not installed
[root@L-server ~]#
[root@L-server ~]# cat /etc/yum.repos.d/server.repo
[rhel5]
name=Red Hat Enterprise Linux 5
baseurl=file:///media/Server
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[root@L-server ~]# mount /dev/cdrom /media/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@L-server ~]#
[root@L-server ~]# mount | tail -1
/dev/sr0 on /media type iso9660 (ro)
[root@L-server ~]#
[root@L-server ~]# tail -1 /etc/fstab
/dev/cdrom /media ext3 defaults 0 0
[root@L-server ~]#
挂载成功并设置了开机自动挂载
[root@L-server ~]# yum -y install dhcp

[root@L-server ~]#
dhcp安装完成，接下来该配置服务喽
配置完成，给另一台作为客户端的服务器预留了IP地址
[root@L-server ~]# cat /etc/dhcpd.conf
ddns-update-style interim;

}
}
[root@L-server ~]#
[root@L-server ~]# /etc/init.d/dhcpd configtest

[root@L-server ~]#
重启服务
[root@L-server ~]# /etc/init.d/dhcpd start
启动 dhcpd： [确定]
[root@L-server ~]# chkconfig dhcpd on
[root@L-server ~]#
[root@L-server ~]# netstat -tulnp | grep dhcpd
