应用介绍

在某些Linux发行版中，通过自动命名生成的接口名称可能很长且很不方便。这篇文章将说明一种更改接口名称的方法。

安装程序应包括一台装有Mellanox适配器的服务器，该服务器已安装了最新的MLNX_OFED软件堆栈。

配置

1.      找到要更改其名称的端口的MAC地址（例如，enp2s0f0和enp2s0f1）：

# ifconfig
enp2s0f0:flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 1.1.1.2 netmask 255.255.255.0broadcast 1.1.1.255
inet6 fe80::7efe:90ff:fecb:7602prefixlen 64 scopeid 0x20<link>
ether 7c:fe:90:cb:76:02txqueuelen 1000 (Ethernet)
RX packets 38 bytes 7321 (7.1 KiB)
RX errors 0 dropped 0 overruns 0frame 0
TX packets 1 bytes 70 (70.0 B)
TX errors 0 dropped 0 overruns 0carrier 0 collisions 0
enp2s0f1:flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 7c:fe:90:cb:76:03txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0carrier 0 collisions 0

2.      创建配置文件（70-persistent-net.rules）

# vim /etc/udev/rules.d/70-persistent-net.rules

在每个相关端口添加以下行。在每个端口上添加MAC地址和新名称。

SUBSYSTEM=="net",ACTION=="add", DRIVERS=="?*", ATTR{address}=="7c:fe:90:cb:76:02",ATTR{dev_id}=="0x0", ATTR{type}=="1",KERNEL=="eth*", NAME="eth1"
SUBSYSTEM=="net",ACTION=="add", DRIVERS=="?*", ATTR{address}=="7c:fe:90:cb:76:03",ATTR{dev_id}=="0x0", ATTR{type}=="1",KERNEL=="eth*", NAME="eth2"

3.      创建/编辑用于端口配置的ifcfg文件：

#cat /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE="eth1"
BOOTPROTO="static"
HWADDR="7c:fe:90:cb:76:02"
IPADDR=1.1.1.2
NETMASK=255.255.255.0
ONBOOT="yes"

4.      重新启动服务器，然后通过运行ifconfig验证名称更改。

# ifconfig

eth1:flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

inet 1.1.1.2 netmask 255.255.255.0 broadcast 1.1.1.255

inet6 fe80::7efe:90ff:fecb:7602 prefixlen64 scopeid 0x20<link>

ether 7c:fe:90:cb:76:02txqueuelen 1000 (Ethernet)

RX packets 0 bytes 0 (0.0 B)

RX errors 0 dropped 0 overruns 0frame 0

TX packets 23 bytes 3208 (3.1 KiB)

TX errors 0 dropped 0 overruns 0carrier 0 collisions 0

eth2:flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

ether 7c:fe:90:cb:76:03 txqueuelen1000 (Ethernet)

RX packets 0 bytes 0 (0.0 B)

RX errors 0 dropped 0 overruns 0frame 0

TX packets 0 bytes 0 (0.0 B)

TX errors 0 dropped 0 overruns 0carrier 0 collisions 0
