安装黑马配置好的虚拟机,但是虚拟机网络不可用,出现了renetlink answers: file exists问题

问题如下:

[root@localhost network-scripts]# systemctl restart network
Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
[root@localhost network-scripts]# systemctl status network.service

 解决问题操作了两步:

第一步:

关闭NetworkManager

systemctl stop NetworkManager
systemctl disable NetworkManager

第二步:

ifdown eno16777736
# eno16777736是网卡的名字(ifconfig能查看到)
