  RedHat是运用广泛的Linux系统,在RedHat6.5的版本中,在联网的时候经常会遇到一些网卡问题,今天华军小编给大家展示的是RedHat6.5网卡常见问题及解决方法,精心挑选的内容希望大家多多支持、多多分享,喜欢就赶紧get哦!。  1、找不到eth0文件  在使用RedHat6.5,新装好的系统,发现没有eth0网卡,默认的第一个网卡是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  解决方法:  直接更名ifcfg-Auto_eth0文件为eth0,重启网卡后会发现,网卡名已经变为eth0  [root@rac01 ~]# service network restart  Bringing up loopback interface: [ OK ]  Bringing up interface eth0: Active connection state: activated  2、ifconfig 发现网卡服务名并未更改  [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)  解决方法:  每次更改RedHat的网卡信息,RedHat会自动的将网卡的MAC地址和对应的网卡服务名关系记录在/etc/udev/rules.d/70-persistent-net.rules中,修改里面的对应服务名即可  [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”  修改完成后需重启一下系统,再次查看网卡服务名已经更改  [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)
