ошибка в конфиге DHCP на centos6

Я пытался настроить DHCP на centos 6. моя конфигурация eth0:

[centos@localhost ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"  
BOOTPROTO="dhcp"
HWADDR="00:0C:29:AE:62:BC"
MTU="1500" 
NM_CONTROLLED="yes"
ONBOOT="yes"
[centos@localhost ~]$ 

я устанавливаю dhcp:

#yum -y install dhcp

результат, который я вижу:

 Error Summary
  -------------

когда я хочу запустить DHCP-сервер во время загрузки, я использую код:

#chkconfig dhcpd on

но я вижу ошибку:

error reading information  on service dhcp:No such file or directory

также когда я перехожу в каталог '/ etc / sysconfig / dhcpd', там нет файла dhcpd. Может кто-нибудь помочь мне? Спасибо.
