方法一：禁用该可预测命名规则
1、对于这一点，你可以在启动时传递“net.ifnames=0 biosdevname=0 ”的内核参数。这是通过编辑/etc/default/grub并加入“net.ifnames=0 biosdevname=0 ”到GRUBCMDLINELINUX变量来实现的。
cat/etc/sysconfig/grub GRUB_TIMEOUT=5 GRUB_disTRIBUTOR="$(sed's,release.*$,g'/etc/system-release)" GRUB_DEFAULT=saved GRUB_disABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="ipv6.disable=1crashkernel=autorhgbquietnet.ifnames=0biosdevname=0" GRUB_disABLE_RECOVERY="true"
2、运行命令grub2-mkconfig -o /boot/grub2/grub.cfg来重新生成GRUB配置并更新内核参数。
3、reboot
1、文件没有的话可以手动创建，后缀是.rules，按照顺序将MAC地址与网卡名称绑定
cat/etc/udev/rules.d/70-persistent-ipoib.rules #Thisisasampleudevrulesfilethatdemonstrateshowtogetudevto #setthenameofIPoIBinterfacestowhateveryouwish.Thereisa #16characterlimitonnetworkdevicenamesthough,sodon'tgotoonuts # #Importantitemstonote:ATTR{type}=="32"isIPoIBinterfaces,andthe #ATTR{address}matchmuststartwith?*andonlyreferencethelast8 #bytesoftheaddressorelsetheaddressmightnotmatchonanygiven #startoftheIPoIBstack # #Note:asofrhel7,udeviscasesensitiveontheaddressfieldmatch #andalladdressesneedtobeinlowercase. # #ACTION=="add",SUBSYstem=="net",DRIVERS=="?*",ATTR{type}=="32",ATTR{address}=="?*00:02:c9:03:00:31:78:f2",NAME="mlx4_ib3" ACTION=="add",ATTR{address}=="?*00:0c:29:7a:1e:16",NAME="eth0"
2、修改网卡配置文件，配置DEVICE和NAME，并加入HWADDR
注：DEVICE、NAME和HWADDR 要和.rules 里面相对应
cat/etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes NAME=eth0 #UUID=408326bb-7565-4aa5-b156-c89a0ba839d2 HWADDR=00:0c:29:7a:1e:16 DEVICE=eth0 ONBOOT=yes IPADDR=172.16.18.188 NETMASK=255.255.255.0 GATEWAY=172.16.18.1 DNS=219.141.136.10
3、reboot
