Linux(Centos 7.6)网卡信息没有了题目处置惩罚

1.题目征象

捏造机打开后，利用ifconfig检察IP信息，捏造机默认的网卡名称是ens33，ifconfig没有看到干系题目，长途毗连工具Xshell也不能正常访问该捏造机。

2. [root@node1 ~]# ifconfig
3. lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
4.         inet 127.0.0.1  netmask 255.0.0.0

2.办理方法

重启网络干系服务。

2. [root@node1 ~]# systemctl restart NetworkManager
3. [root@node1 ~]# systemctl restart network.service

复制代码

重启网络干系服务后ifconfig检察网络信息如下，可以正常毗连。

2. [root@node1 ~]# ifconfig
