一、DHCP服务器上安装配置DHCP：
[root@zengqingfu ~]# rpm -qi dhcp
package dhcp is not installed
[root@zengqingfu ~]# mount
/dev/mapper/vg_h1-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
/dev/sr0 on /media/cdrom type iso9660 (ro)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
注意不要开启本地的DHCP服务：
测试：在DHCP服务器中主机声明
客户机的eth0的Mac地址
