添加网卡到配置文件，并且命名为eth1

[root@localhost ~]# nmcli connection add ifname eno33554992 con-name eth1 type ethernet 
Connection 'eth1' (5f1fde10-d2a2-4ea5-8213-7cdb53bb59bf) successfully added.

       valid_lft forever preferred_lft forever

修改网络配置文件添加MAC地址 (eno33554992) 、修改BOOTPROTO=static 修改设备名DEVICE=eth1

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no

DEVICE=eth1
ONBOOT=yes
HWADDR=00:0c:29:4d:bb:5d

重启服务器之后 查看ip

[root@localhost ~]# ip a

UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:4d:bb:5d brd ff:ff:ff:ff:ff:ff

添加ip地址

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1
