LINUX安装好后无法访问网络
在虚拟机安装好新的LINUX系统后，ping www.baidu.com ，发现无法ping通。
键入ifconfig查询配置：
|
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 |
|
ether 00:0c:29:3e:ad:2d txqueuelen 1000 (Ethernet) |
|

得到本机的网卡是eno16777728
然后，重启网卡服务：service network restart
再次查询：ifconfig,发现依旧如上所示，并且无法访问网络。
修改网卡配置： root模式下vim /etc/sysconfig/network-scripts/ifcfg-eno16777728（最后的数字不一定一致，不要照搬，根据查询出来的配置信息灵活替换），然后将文件里最后一项的ONBOOT=no在插入模式中修改为yes并保存退出,以后计算机自动启动网卡。
现在手动启动网卡服务ifup eno16777736
重新键入ifconfig：
|
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 |
|
inet 192.168.81.134 netmask 255.255.255.0 broadcast 192.168.81.255 |

问题解决，网卡服务成功启动，并且后续不需要每次都手动启动网卡服务
