问一个DHCP服务器的问题

myvios

系统是CentOS6.5，/etc/dhcp/dhcpd.conf，/etc/sysconfig/dhcpd 等文件都已经配置好
命令行运行/usr/sbin/dhcpd 可以成功启动dhcp服务，但是运行service dhcp start总是【失败】，
查看/var/log/message，如下：

感觉问题在lease file的权限上，百度谷歌两天不得解答，还请各位高手帮忙查错

myvios

lease file的权限如下
-rw-r--r--. 1 root root 192 11月 19 17:49 /var/lib/dhcpd/dhcpd.leases

从/etc/rc.d/init.d/dhcpd看运行脚本，启动用户是dhcpd

prog=dhcpd
user=dhcpd
group=dhcpd
exec=/usr/sbin/dhcpd
lockfile=/var/lock/subsys/dhcpd
pidfile=/var/run/dhcpd.pid
statedir=/var/lib/dhcpd

再查看/etc/passwd
dhcpd:177:177HCP server:/:/sbin/nologin

将leasefile的权限改成dhcpd:dhcpd，也没用，头都大了。
求解救！

首先注意如果是版本是dhcp 3.XXX,配置文件为/etc/dhcpd.conf(没有就新建)
如果是dhcp 4.XXX,配置文件为/etc/dhcp/dhcpd.conf（没有就新建）
1 进入dhcpd运行文件   vim  /etc/rc.d/init.d/dhcpd
2 将权限user=dhcpd   改为 user=root；  group=dhcpd改为group=root 。 将dhcp相关配置文件的用户和组都改为root

哈，果然把user和group都改为root就成功了，那既然如此，系统在安装dhcp服务后创建一个不能启动服务的dhcp：dhcp用户和组又有什么意义呢？
而且手头上几本书都没有写明这点。
