2.

vi  ifcfg-em1

內容爲：其中NETWORK=192.168.100.0 那一行，一開始我寫的是GATEWAY=192.168.100.0，配置完後上不了外網，遂改爲NETWORK=192.168.100.0

TYPE="Ethernet"
#BOOTPROTO="dhcp"
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"

3.添加dns  vi/etc/resolv.conf 添加8.8.8.8 和  4.4.4.4

nameserver=202.102.152.3
nameserver=202.102.154.3
nameserver 8.8.8.8
