同2问题类似，即可以手动的修改70-persistent-net.rules文件，将对应的MAC地址与网卡序号改成想要的，也可以直接删除该文件，重启系统后，RedHat会自动的创建该文件，并从0开始计数。
[root@rac01 ~]# mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/7
[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:206 errors:0 dropped:0 overruns:0 frame:0 TX packets:68 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:19282 (18.8 KiB) TX bytes:7215 (7.0 KiB) eth1 Link encap:Ethernet HWaddr 00:0C:29:1E:F6:B7 inet addr:10.109.67.83 Bcast:10.109.67.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe1e:f6b7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:131 errors:0 dropped:0 overruns:0 frame:0 TX packets:11 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8736 (8.5 KiB) TX bytes:746 (746.0 b) |
4、每次重启网卡，总是提示
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/9
此时网卡也可以正常通信，这个是因为RedHat自己开发的NetworkManager管理工具和/etc/sysconfig/network-scripts/ifcfg-ethx配置不同步造成的。
解决方法：
要消除这个提示，请关闭NetworkManager服务即可：
[root@rac01 ~]# service network restart Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/2 [ OK ] Bringing up interface eth1: Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/3 [ OK ] |
关闭NetworkManager服务
[root@rac01 ~]# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
再次重启网卡
[root@rac01 ~]# service network restart
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
Bringing up interface eth1: [ OK ]
5、重启网卡出现提示：
Bringing up interface eth0: Determining if ip address 10.109.67.81 is already in use for device eth0...
[ OK ]
Bringing up interface eth1: Determining if ip address 10.109.67.83 is already in use for device eth1...
[ OK ]
该警告一般是由于网卡解析arp协议导致的，可在网卡的配置文件中加入ARPCHECK=NO参数来屏蔽该检查
[root@rac01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=none IPADDR=10.109.67.81 PREFIX=24 GATEWAY=10.109.67.254 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 ARPCHECK=no |
再次启动网卡，一切正常
[root@rac01 ~]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down interface eth1: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
Bringing up interface eth1: [ OK ]
