Modify any network card name

1. Check the name of the network card (here is ens3, it needs to be changed to ens192)

[root@kubernetes-node3 network-scripts]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 52:54:00:26:1f:7e brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.34/24 brd 192.168.122.255 scope global dynamic ens3
       valid_lft 86146sec preferred_lft 86146sec
    inet6 fe80::e680:5eea:464c:3847/64 scope link 
       valid_lft forever preferred_lft forever

2. Create a new configuration file 70-persistent-net.rules

[root@kubernetes-node3 ~]# cd /etc/udev/rules.d
[root@kubernetes-node3 ~]# vim 70-persistent-net.rules

Write the following content

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:54:00:26:1f:7e", NAME="ens192"
注意：这个规则将根据网卡的 MAC 地址将其命名为"ens33"。你需要将ATTR{address}=="52:54:00:26:1f:7e" 部分替换为你要更改名称的网卡的 MAC 地址。

3. Update udev rules: Run the following command to update udev rules

[root@kubernetes-node3 ~]# udevadm trigger

4. Restart the server

[root@kubernetes-node3 ~]# reboot

5. Check whether the network card name takes effect after the server is restarted

[root@kubernetes-node3 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 52:54:00:26:1f:7e brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.165/24 brd 192.168.122.255 scope global ens192
       valid_lft forever preferred_lft forever
    inet6 fe80::5054:ff:fe26:1f7e/64 scope link 
       valid_lft forever preferred_lft forever

Note: From the above information, we can see that the network card name and ip address have been changed, indicating that we have successfully modified
