RHEL7添加一張自定義網(wǎng)卡并更改網(wǎng)卡接口
本篇文章重點(diǎn)為大家講解一下RHEL7添加一張自定義網(wǎng)卡并更改網(wǎng)卡接口具體方法，有需要的小伙伴可以參考一下。
十年的都安網(wǎng)站建設(shè)經(jīng)驗(yàn)，針對(duì)設(shè)計(jì)、前端、開(kāi)發(fā)、售后、文案、推廣等六對(duì)一服務(wù)，響應(yīng)快，48小時(shí)及時(shí)工作處理。成都全網(wǎng)營(yíng)銷(xiāo)推廣的優(yōu)勢(shì)是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同，自動(dòng)調(diào)整都安建站的顯示方式，使網(wǎng)站能夠適用不同顯示終端，在瀏覽器中調(diào)整網(wǎng)站的寬度，無(wú)論在任何一種瀏覽器上瀏覽網(wǎng)站，都能展現(xiàn)優(yōu)雅布局與設(shè)計(jì)，從而大程度地提升瀏覽體驗(yàn)。創(chuàng)新互聯(lián)從事“都安網(wǎng)站設(shè)計(jì)”,“都安網(wǎng)站推廣”以來(lái)，每個(gè)客戶項(xiàng)目都認(rèn)真落實(shí)執(zhí)行。

添加網(wǎng)卡后，需要?jiǎng)?chuàng)建對(duì)應(yīng)的網(wǎng)卡配置文件
[root@Jaking network-scripts]# cp ifcfg-ens33 ifcfg-ens34
[root@Jaking network-scripts]# vim ifcfg-ens34
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
NAME=ens34
DEVICE=ens34
ONBOOT=yes
IPADDR=172.16.100.100
NETMASK=255.255.255.0
禁用ens38接口
[root@Jaking network-scripts]# ip link set ens38 down
[root@Jaking network-scripts]# ifconfig

重命名ens38接口為ens34
[root@Jaking network-scripts]# ip link set ens38 name ens34
啟用修改完成的ens34接口
[root@Jaking network-scripts]# ip link set ens34 up
[root@Jaking network-scripts]# systemctl restart network
[root@Jaking network-scripts]# ifconfig
