我试图在centos上configurationDHCP 6.my eth0的configuration是：
[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 ~]$ 我通过安装dhcp：
#yum -y install dhcp
我看到的结果是：

当我想使DHCP服务器启动时，我使用代码：
#chkconfig dhcpd on
但我看到错误：
error reading information on service dhcp:No such file or directory
另外当我去'/ etc / sysconfig / dhcpd'目录时，没有任何dhcpd文件。 谁能帮我？ 谢谢。
这看起来像你还没有真正安装你可以检查的DHCP包
yum list installed | grep dhcp
检查包裹
dhcp.x86_64 12:4.1.1-31.0.1.P1.el6.centos.1 @updates
或类似的安装。 您还应该检查/var/log/yum.log文件以获取相关信息。
编辑：OP没有注意到，yum安装命令不起作用。 这是由来自不同软件包的冲突文件造成的。 一个
yum update dhclient
解决了允许然后进行的冲突。
