今天在自己的虚拟机导入了一份awr数据,同事需要看我就在虚拟机系统里添加了网卡的网卡,但是发现7以后配置网卡的方式稍微存在点变化,可以使用一下方法配置
- nmtui– network manager 图形界面
- nmcli– network manager command
- ip — ip command
查看网卡
[root@oel7 network-scripts]# nmcli dev status
DEVICE TYPE STATE CONNECTION
enp0s3 ethernet connected enp0s3
enp0s8 ethernet connected enp0s8
enp0s9 ethernet disconnected --
lo loopback unmanaged --
显示了本机存在三个网卡 |
查看网络连接状态
[root@oel7 network-scripts]# nmcli con show

enp0s9 网卡上没有网络接口存在 |
添加网络接口
