  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,下面小编给大家整理了RedHat6.5网卡常见的问题及解决方法,希望对你有所帮助。  RedHat6.5网卡常见问题及解决方法   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)
