vmware虛擬機實現雙網卡固定ip

vmware 可以添加兩個網卡
一個網卡連接外網：使用NAT
一個網卡用於內網連接，使用主機模式
如何添加兩個網卡
1.
2.
3.
虛擬機內部設置
假定條件：你內部網卡配置是正確的
進入網卡設置文件夾

執行ifconfig -a 可以看到你的網卡

你會看到有除了lo還有eth0和eth1兩個ip

/etc/sysconfig/network-scripts
cp ifcfg-eth0 ifcfg-eth1 
//ifcfg-eth1可以設置爲自己喜歡的形式，可以是eth2或者eth3,我這裏改爲eth2
這個主要是爲了配置靜態IP使用

修改你增加的配置：

[root@localhost network-scripts]# vim ifcfg-eth2

DEVICE=eth2
#DEFROUTE=yes
#PEERROUTES=yes
#IPV4_FAILURE_FATAL=no
#HWADDR=00:0C:29:84:35:09
HWADDR=00:0C:29:7C:00:34
//HWADDR是你剛纔設置的MAC
#TYPE=Ethernet
#UUID=fc55680e-fd46-4575-a21b-03928b6b5f9f
ONBOOT=on
#NM_CONTROLLED=yes
BOOTPROTO=static
//IP是靜態，你可以設置一個IP
IPADDR=192.168.21.135
NETMASK=255.255.255.0
NAME=eth2

重新加載重啓
service network restart
或者/etc/init.d/network restart

問題解決方法
找到網絡配置規則

vim /etc/udev/rules.d/70-persistent-70-persistent-cd.rules

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:7c:00:34", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:7c:00:2a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

確保你配置中的MAC地址和名字與ATTR{address}和NAME="eth0"一一對應就可以了。
