vmware 可以新增兩個網絡卡
一個網絡卡連線外網：使用NAT
一個網絡卡用於內網連線，使用主機模式
如何新增兩個網絡卡
1.
2.
3.
虛擬機器內部設定
假定條件：你內部網絡卡配置是正確的
進入網絡卡設定資料夾

/etc/sysconfig/network-scripts
cp ifcfg-eth0 ifcfg-eth2 
//ifcfg-eth2可以設定為自己喜歡的形式

修改你增加的配置：

[[email protected] 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是你剛才設定的MAC
#TYPE=Ethernet
#UUID=fc55680e-fd46-4575-a21b-03928b6b5f9f
ONBOOT=on
#NM_CONTROLLED=yes
BOOTPROTO=static
//IP是靜態，你可以設定一個IP
IPADDR=192.168.21.135
NETMASK=255.255.255.0
NAME=eth2

重新載入重啟
service network restart
或者/etc/init.d/network restart

問題解決方法
找到網路配置規則

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。
