【基礎設置】修改網卡設備名稱

vm使用克隆出來的虛擬機，網卡名稱變成eth1，要把這個eth1改爲eth0，參照以下步驟：

1. 查看eth1對應的mac地址
   

   ifconfig

   如：eth1:00:0C:29:74:F2:99

2. 修改/etc/sysconfig/network-scripts/ifcfg-eth0的mac地址爲eth1的mac地址

   因爲vm克隆過來，network-scripts目錄下沒有eth1的文件，目錄下有一個ifcfg-eth0，修改以下：

hwaddr由原來的mac改爲eth1的mac，保存。

DEVICE=eth0

HWADDR=00:0C:29:74:F2:99

ONBOOT=yes

IPADDR=192.168.198.10

BOOTPROTO=none

NETMASK=255.255.255.0

TYPE=Ethernet

GATEWAY=192.198.198.2

    

3. 修改/etc/udev/rules.d/70-persistent-net.rules文件

attr{address} 與 name兩個字段

[root@nginx rules.d]# cat 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 0x1022:0x2000 (pcnet32)

# SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:55:61:94", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1022:0x2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:74:f2:99", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

[root@nginx rules.d]# 

4. 重啓系統
