Redhat AS 6 修改网卡名

需求：

将 eth4 和 eth5 修改为需要的 eth0, eth1 以便进行 RAC 的安装

解决方法： mii-tool 重置网络名

[root@rac02 network-scripts]# mii-tool -r eth0
restarting autonegotiation...
[root@rac02 network-scripts]# mii-tool -r eth1
restarting autonegotiation...

1. 版本 AS6.2
cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.2 (Santiago)

2. 网络配置文件
[root@rac02 network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@rac02 network-scripts]# ls ifcfg-eth*
ifcfg-eth0 ifcfg-eth1

3. 网卡IP
[root@rac02 network-scripts]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
     inet6 ::1/128 scope host
        valid_lft forever preferred_lft forever
2: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
     link/ether 08:00:27:38:4e:7c brd ff:ff:ff:ff:ff:ff
     inet 192.168.1.106/24 brd 192.168.1.255 scope global eth4
     inet6 fe80::a00:27ff:fe38:4e7c/64 scope link
        valid_lft forever preferred_lft forever
3: eth5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
     link/ether 08:00:27:a0:3f:31 brd ff:ff:ff:ff:ff:ff
     inet 192.168.1.103/24 brd 192.168.1.255 scope global eth5
     inet6 fe80::a00:27ff:fea0:3f31/64 scope link
        valid_lft forever preferred_lft forever

4. 无 modprobe.conf 文件
[root@rac02 ~]# find / -name "modprobe.conf"
[root@rac02 ~]#

5. 解决方法： mii-tool 重置网络名

[root@rac02 network-scripts]# mii-tool -r eth0
restarting autonegotiation...
[root@rac02 network-scripts]# mii-tool -r eth1
restarting autonegotiation...

6. 解决后的效果

[root@rac02 ~]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:38:4e:7c brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.12/24 brd 192.168.1.255 scope global eth0
    inet6 fe80::a00:27ff:fe38:4e7c/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:a0:3f:31 brd ff:ff:ff:ff:ff:ff
    inet 10.10.10.2/8 brd 10.255.255.255 scope global eth1
    inet6 fe80::a00:27ff:fea0:3f31/64 scope link
       valid_lft forever preferred_lft forever
