我现在想通过网络安装ubuntu系统,不过在第一步dhcp中就出现了问题,提示如图片。环境如下:os:ubuntu12.04 dhcp-server ip:192.168.100.250 通过dnsmasq去管理dhcp和tftp等软件,
dhcp配置文件 /etc/dhcp/dhcpd.conf如下:
subnet 192.168.100.0 netmask 255.255.128.0{
range 192.168.100.18 192.168.100.50;
}
dnsmasq配置文件 /etc/dnsmasq.conf如下:
dhcp-range=192.168.100.18,192.168.100.50,24h
dhcp-boot=pxelinux.0
enable-tftp
tftp-root=/var/lib/tftpboot
dhcp-authoritative
dhcp-option=3,192.168.100.250
在dhcp-server上,ps一下,查看dhcp的进程,结果如下:
root@Front:~# ps aux | grep dhcp
111 2066 0.0 0.0 25972 1004 ? S Nov04 0:00 /usr/sbin/dnsmasq -u libvirt-dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override
root 19901 0.0 0.0 9792 976 pts/2 S+ 09:44 0:00 grep --color=auto dhcp
关键是,之前我在之前某个局域网中这么装成功过一次,真不知道是什么原因了,请各位指教
