在配置完DHCP後，執行
/etc/init.d/dhcpd restart
執行結果失敗
查找DHCP執行日誌：
cat /var/log/messages
報錯：

問題描述：
通過以下這句，和無數次搜索得知，問題可能是由於dhcpd權限問題導致
CentOS6 dhcpd: Can't chown new lease file: Operation not permitted
解決方案：
修改/etc/init.d/dhcpd執行語句如下：
vi /etc/init.d/dhcpd
修改其中的
user=dhcpd
gropu=dhcpd
把dhcpd替換爲即可
user=root
group=root
再次啓動
/etc/init.d/dhcpd restart
還是執行失敗==！！！
enen,至少不是這個問題了
繼續排除ing，吐血ing。。。。
待續。。。。
