RedHat是運用廣泛的Linux系統,在RedHat6.5的版本中,在聯網的時候經常會遇到一些網卡問題,下面小編給大家整理了RedHat6.5網卡常見的問題及解決方法,希望對你有所幫助。
1、找不到eth0文件
在使用RedHat6.5,新裝好的系統,發現沒有eth0網卡,默認的第一個網卡是Auto-eth0
[root@rac01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-Auto_eth0
TYPE=Ethernet
BOOTPROTO=none
IPADDR=10.10.10.110
PREFIX=24
GATEWAY=10.10.10.111
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME=eth0
UUID=86d44060-4579-48cc-b85b-219a206ca37c
ONBOOT=yes
HWADDR=00:50:56:95:09:76
LAST_CONNECT=1411004329
解決方法:
直接更名ifcfg-Auto_eth0文件為eth0,重啟網卡後會發現,網卡名已經變為eth0
[root@rac01 ~]# service network restart
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Active connection state: activated
2、ifconfig 發現網卡服務名並未更改
[root@rac01 ~]# ifconfig
Auto_eth0 Link encap:Ethernet HWaddr 00:50:56:95:09:76
inet addr:10.10.10.110 Bcast:10.10.10.111 Mask:255.255.255.0
inet6 addr: fe80::250:56ff:fe95:976/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:484 errors:0 dropped:0 overruns:0 frame:0
TX packets:57 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:40095 (39.1 KiB) TX bytes:6271 (6.1 KiB)
解決方法:
每次更改RedHat的網卡信息,RedHat會自動的將網卡的MAC地址和對應的網卡服務名關系記錄在/etc/udev/rules.d/70-persistent-net.rules中,修改裡面的對應服務名即可
[root@rac01 ~]# vim /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM==“net”, ACTION==“add”, DRIVERS==“?*”, ATTR{address}==“00:0c:29:1e:f6:ad”, ATTR{type}==“1”, KERNEL==“eth*”, NAME=“eth0”
修改完成後需重啟一下系統,再次查看網卡服務名已經更改
[root@rac01 ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:50:56:95:09:76
inet addr:10.109.67.81 Bcast:10.109.67.255 Mask:255.255.255.0
inet6 addr: fe80::250:56ff:fe95:976/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:985 errors:0 dropped:0 overruns:0 frame:0
TX packets:61 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:74395 (72.6 KiB) TX bytes:6527 (6.3 KiB)
