解决办法:

  1. 如果新加网卡或者克隆虚拟机,可能是 mac 地址不对,使用 ip addr 查看mac地址
    • 永久修改:

然后把  /etc/sysconfig/network-scripts/ifcfg-ens33(MACADDR) 或者 /sys/class/net/ens33/address

    • 临时修改:

#ifconfig eth0 down /*禁掉eth0网卡,这里以eth0网卡为例*/

#ifconfig eth0 hw ether 00:AA:BB:CC:DD:EE /*修改eth0网卡的MAC地址*/

#ifconfig eth0 up   /*重新启动eth0网卡*/

        2. Mac 没问题,关闭系统的 NetworkManager , 注意大小写
