请教设置 isc-dhcp-server 运行失败的问题

[bugmenott]

系统 debian7.7 3.16.7-x86_64-linode49

这是/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp



这是/etc/default/isc-dhcp-server
# Defaults for isc-dhcp-server initscript
# sourced by /etc/init.d/isc-dhcp-server
# installed at /etc/default/isc-dhcp-server by the maintainer scripts

#
# This is a POSIX shell fragment
#

# Path to dhcpd's config file (default: /etc/dhcp/dhcpd.conf).
#DHCPD_CONF=/etc/dhcp/dhcpd.conf

# Path to dhcpd's PID file (default: /var/run/dhcpd.pid).
#DHCPD_PID=/var/run/dhcpd.pid

# Additional options to start dhcpd with.
# Don't use options -cf or -pf here; use DHCPD_CONF/ DHCPD_PID instead
#OPTIONS=""

# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?
# Separate multiple interfaces with spaces, e.g. "eth0 eth1".
INTERFACES="eth0"


这是 /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.10 192.168.2.20;
option domain-name-servers 129.250.35.250, 129.250.35.251;
option routers 192.168.2.1;
option broadcast-address 192.168.2.255;
default-lease-time 600;
max-lease-time 7200;
}



然后 service isc-dhcp-server start 失败了
[FAIL] Starting ISC DHCP server: dhcpd[....] check syslog for diagnostics. ... failed!
failed!



这是 /var/log/syslog
No subnet declaration for eth0 (106.187.*.*).
** If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth0 is attached. **

我比较白，完全不知道该怎么搞了

eth0 ip地址没配置好
