或指定启动关闭某个网卡命令
ifdown enp0s3    （关闭网卡enp0s3）
ifup   enp0s3    (启动网卡enp0s3)
service network-manager restart

四、ubuntu18-ubuntu20网卡配置

1
vi /etc/netplan/**  ##默认01/00数字开头文件

此版本对配置文件格式要求严格，错一步就会导致整张网卡报错

#centos7 重启网卡
#命令1
/etc/init.d/network restart
#命令2
systemctl restart network  

#centos8重启网卡
nmcli connection reload

#不能立即生效的命令
nmcli d c eno1

nmcli c r eno1

nmcli d r eno1

#一次运行
nmcli d c eno1&&nmcli c r eno1&&nmcli d r eno1

重启失败，检查网卡配置文件内容，如无误，centos6建议直接重启，centos7一般是NetworkManager服务限制了，可以关闭服务重试

1
systemctl stop NetworkManager && systemctl restart network && sleep 5s && systemctl start NetworkManager

NetworkManager服务开启也可以用nmtui命令进入图形界面配置网卡
