我们修改分辨率，需要在kernel那行加入 vga=791
三配置网络
找到 /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=ens33
UUID=012d4f52-bbd0-4d11-b2dc-b83f00208f9f
DEVICE=ens33
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.1.121
GATWAY=192.168.1.1
DNS=8.8.8.8
重启 就可以连上局域网了。
四 安装ifconfig命令
新安装centos时找不到 ifconfig命令
需要安装 具体操作时 yum install net-tools命令 ok
[root@localhost network-scripts]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

[root@localhost network-scripts]#
最后还是有问题，在虚拟机里面不能访问外网，是网关没有配配置好
必须改vi /etc/sysconfig/network
加上
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.1.1
重启网络服务
service network restart
[root@localhost ~]# ping www.baidu.com
PING www.a.shifen.com (119.75.217.109) 56(84) bytes of data.

^C
搞定
