CentOS6.5 上装了 DHCP 配置好之后,用 "sudo service dhcpd start" 启动报错,但是用 "sudo dhcp" 可以启动,然后查看
"/var/log/messages" 文件  tail -f  /var/log/messages |grep dhcpd

Feb  3 09:12:32 dhcphost dhcpd: Internet Systems Consortium DHCP Server 4.1.1-P1
Feb  3 09:12:32 dhcphost dhcpd: Copyright 2004-2010 Internet Systems Consortium.

Feb  3 09:12:32 dhcphost dhcpd: Not searching LDAP since ldap-server, ldap-port and ldap-base-dn were not specified in the config file

Feb  3 09:12:32 dhcphost dhcpd:

Feb  3 09:12:32 dhcphost dhcpd: it work better with this distribution.

Feb  3 09:12:32 dhcphost dhcpd: Please report for this software via the CentOS Bugs Database:
Feb  3 09:12:32 dhcphost dhcpd:    http://bugs.centos.org/
Feb  3 09:12:32 dhcphost dhcpd:
Feb  3 09:12:32 dhcphost dhcpd: exiting.

其中这一行引起注意

Feb  3 09:12:32 dhcphost dhcpd: Can't chown new lease file: Operation not permitted

于是检查 /etc/rc.d/init.d/dhcpd 文件,发现其中有如下两行定义了启动dhcp的user和group

user=dhcpd

group=dhcpd

想到上面提到的用 "sudo service dhcpd start" 不能启动而用 "sudo dhcp" 可以启动,想到可能是用户权限问题,于是把这两个参数修改为:

user=root

group=root

然后再使用 "sudo service dhcpd start" 启动DHCP,问题解决。
