好像是网卡没启动吧…

我的物理机是win10，周末把电脑关了，在周一打开时，时不时会遇到，虚拟机开机没有网的问题，查看服务却又全都启动了诶…
服务和应用管理

直接执行命令，重启网卡

sudo service network-manager stop
sudo rm /var/lib/NetworkManager/NetworkManager.state
sudo service network-manager start

解决过程

ifconfig 查看网络信息发现没有网卡

$ ifconfig 
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (本地环回)
        RX packets 193  bytes 14541 (14.5 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 193  bytes 14541 (14.5 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

执行重启命令

$ sudo service network-manager stop
$ sudo rm /var/lib/NetworkManager/NetworkManager.state
$ sudo service network-manager start

再次查看网卡信息

$ ifconfig 
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.***.140  netmask 255.255.255.0  broadcast 192.168.***.255
        inet6 fe80::517d:39f1:9771:978b  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:3e:51:8d  txqueuelen 1000  (以太网)

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 43  bytes 5172 (5.1 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (本地环回)
        RX packets 452  bytes 32918 (32.9 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 452  bytes 32918 (32.9 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

我把我的IP藏一下应该没啥问题吧

ping 一下试试

ping www.baidu.com
