第一步：nmcli con show
[root@controller ~]# nmcli con show

第二步：ip a 找到mac地址并记录
[root@controller ~]# ip a

第三步：复制以下内容道新建ens36文件
YPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens36
UUID=1035101d-ff6a-3ebe-9a20-03b2005cdd5b
DEVICE=ens36
ONBOOT=yes
IPADDR=192.168.91.130
NETMASK=255.255.255.0
GATEWAY=192.168.91.2
HWADDR=00:0c:29:5b:17:da
第四步：重启网卡
