这篇文章给大家分享的是有关RHEL7中如何添加自定义网卡并更改网卡接口的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

环境

VMware Workstation Pro Red Hat Enterprise Linux Server release 7.3

查看当前网卡信息

[root@Jaking ~]# cat /etc/redhat-releaseRed Hat Enterprise Linux Server release 7.3 (Maipo)[root@Jaking ~]# ifconfigens33: flags=4163  mtu 1500       inet 192.168.10.11  netmask 255.255.255.0  broadcast 192.168.10.255       inet6 fe80::250:56ff:fe2b:88bf  prefixlen 64  scopeid 0x20       ether 00:50:56:2b:88:bf  txqueuelen 1000  (Ethernet)       RX packets 454  bytes 44638 (43.5 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 339  bytes 33150 (32.3 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73  mtu 65536       inet 127.0.0.1  netmask 255.0.0.0       inet6 ::1  prefixlen 128  scopeid 0x10       loop  txqueuelen 1  (Local Loopback)       RX packets 112  bytes 9492 (9.2 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 112  bytes 9492 (9.2 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

添加网卡

取消红框内的钩

查看网卡信息

[root@Jaking ~]# ifconfigens33: flags=4163  mtu 1500       inet 192.168.10.11  netmask 255.255.255.0  broadcast 192.168.10.255       inet6 fe80::250:56ff:fe2b:88bf  prefixlen 64  scopeid 0x20       ether 00:50:56:2b:88:bf  txqueuelen 1000  (Ethernet)       RX packets 488  bytes 47935 (46.8 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 356  bytes 35698 (34.8 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0ens38: flags=4163  mtu 1500       ether 00:0c:29:46:f9:b8  txqueuelen 1000  (Ethernet)       RX packets 5  bytes 594 (594.0 B)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 0  bytes 0 (0.0 B)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73  mtu 65536       inet 127.0.0.1  netmask 255.0.0.0       inet6 ::1  prefixlen 128  scopeid 0x10       loop  txqueuelen 1  (Local Loopback)       RX packets 112  bytes 9492 (9.2 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 112  bytes 9492 (9.2 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

配置网卡并更改网卡接口

[root@Jaking ~]# cd /etc/sysconfig/network-scripts/[root@Jaking network-scripts]# lsifcfg-ens33  ifdown-ipv6    ifdown-TeamPort  ifup-ippp   ifup-routes       network-functionsifcfg-lo     ifdown-isdn    ifdown-tunnel    ifup-ipv6   ifup-sit          network-functions-ipv6ifdown       ifdown-post    ifup             ifup-isdn   ifup-Teamifdown-bnep  ifdown-ppp     ifup-aliases     ifup-plip   ifup-TeamPortifdown-eth   ifdown-routes  ifup-bnep        ifup-plusb  ifup-tunnelifdown-ib    ifdown-sit     ifup-eth         ifup-post   ifup-wirelessifdown-ippp  ifdown-Team    ifup-ib          ifup-ppp    init.ipv6-global

添加网卡后，需要创建对应的网卡配置文件

[root@Jaking network-scripts]# cp ifcfg-ens33 ifcfg-ens34[root@Jaking network-scripts]# vim ifcfg-ens34          TYPE=EthernetBOOTPROTO=staticDEFROUTE=yesPEERDNS=yesPEERROUTES=yesIPV4_FAILURE_FATAL=noNAME=ens34DEVICE=ens34ONBOOT=yesIPADDR=172.16.100.100NETMASK=255.255.255.0

禁用ens38接口

[root@Jaking network-scripts]# ip link set ens38 down  [root@Jaking network-scripts]# ifconfigens33: flags=4163  mtu 1500       inet 192.168.10.11  netmask 255.255.255.0  broadcast 192.168.10.255       inet6 fe80::250:56ff:fe2b:88bf  prefixlen 64  scopeid 0x20       ether 00:50:56:2b:88:bf  txqueuelen 1000  (Ethernet)       RX packets 812  bytes 74791 (73.0 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 537  bytes 61780 (60.3 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73  mtu 65536       inet 127.0.0.1  netmask 255.0.0.0       inet6 ::1  prefixlen 128  scopeid 0x10       loop  txqueuelen 1  (Local Loopback)       RX packets 112  bytes 9492 (9.2 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 112  bytes 9492 (9.2 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

重命名ens38接口为ens34

[root@Jaking network-scripts]# ip link set ens38 name ens34

启用修改完成的ens34接口

[root@Jaking network-scripts]# ip link set ens34 up                     [root@Jaking network-scripts]# systemctl restart network[root@Jaking network-scripts]# ifconfig                ens33: flags=4163  mtu 1500       inet 192.168.10.11  netmask 255.255.255.0  broadcast 192.168.10.255       inet6 fe80::250:56ff:fe2b:88bf  prefixlen 64  scopeid 0x20       ether 00:50:56:2b:88:bf  txqueuelen 1000  (Ethernet)       RX packets 1389  bytes 123239 (120.3 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 913  bytes 117924 (115.1 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0ens34: flags=4163  mtu 1500       inet 172.16.100.100  netmask 255.255.255.0  broadcast 192.168.100.255       ether 00:0c:29:46:f9:b8  txqueuelen 1000  (Ethernet)       RX packets 5  bytes 594 (594.0 B)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 2  bytes 120 (120.0 B)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73  mtu 65536       inet 127.0.0.1  netmask 255.0.0.0       inet6 ::1  prefixlen 128  scopeid 0x10       loop  txqueuelen 1  (Local Loopback)       RX packets 148  bytes 12552 (12.2 KiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 148  bytes 12552 (12.2 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
