1.安装centos 6.0 dhcp 服务
[[email protected] ~]# yum install dhcp -y Centos6，安装的时候出现， Transaction Check Error: file /usr/share/man/man5/dhcp-eval.5.gz from install of dhcp-common-12:4.1.1-43.P1.el6.centos.i686 conflicts with file from package dhclient-12:4.1.1-12.P1.el6.i686 file /usr/share/man/man5/dhcp-options.5.gz from install of dhcp-common-12:4.1.1-43.P1.el6.centos.i686 conflicts with file from package dhclient-12:4.1.1-12.P1.el6.i686 Error Summary
发现dhclient有冲突，yum remove dhclient，连带的NetworkManager也卸载了。
[[email protected] ~]# yum install dhcp -y 成功安装 [[email protected] ~]# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
[[email protected] ~]# /etc/init.d/dhcpd restart
正在启动 dhcpd： [失败]

以上没有日志找不出什么问题，然后调试命令看看哪里报错了！
