VMware configures different network segment dual NICs.

First, preface

Requirements: Due to the LVS walkthrough, two Linux OS NICs need to be configured and different network segments.

Get ready:

Physical machine: Single NIC

Vmware:centos 6.8

Second, the configuration of the first step: new virtual Machine Vmware,centos 6.8, the default one card eth0. Configured NAT mode,

The network segment I set up here in NAT mode is the 192.168.229.0/24 network segment.

Step two: Add a NIC. The mode is bridged, and the same as the physical machine network segment is the 192.168.1.0/24 network segment.

Here, add up.

The third step, configuration

After the CentOS boot, only one card eth0 information, copy a eth0 configuration file:

[[email protected] network-scripts] #cd/etc/sysconfig/network-scripts

[[email protected] network-scripts] #cp ifcfg-eth0 ifcfg-eth1

To modify the configuration file Ifcfg-eth1:

[Email protected] network-scripts]# cat/etc/udev/rules.d/70-persistent-net.rules# This file is automatically Generated by the/lib/udev/write_net_rules# program, run by the persistent-net-generator.rules rules file.## C An modify it, as long as you keep each rule on a single# line, and change only the value of the name= key.# PCI de Vice 0x8086:0x100f (e1000) subsystem== "NET", action== "Add", drivers== "? *", attr{address}== "00:0c:29:df:72:dd", attr{type}== "1", kernel== "eth*", name= "eth0"# PCI device 0x8086:0x100f (e1000) subsystem== "NET", action== "add" , drivers== "? *", attr{address}== "00:0c:29:df:72:e7", attr{type}== "1", kernel== "eth*", name= "eth1   " 

As you can see, the MAC address of eth1 is: 00:0c:29:df:72:e7, modify/etc/sysconfig/network-scripts/ifcfg-eth1 as follows:

[email protected] network-scripts]# cat ifcfg-eth1 device=eth1hwaddr=00:0c:29:df:72: e7type=  ethernetuuid=a5370cfe-c84a-4b11-97ee-a96f34db9bbaonboot=yesnm_controlled=yesbootproto=static  ipaddr=192.168.1.111netmask=255.255.255.0gateway=192.168.1.1        

Restart the network card: Service network restart.

[Email protected] network-scripts]# Service Network Restart shutting down interface eth0: [OK] closing interface eth1: [OK] close loopback interface: [OK] popup loopback interface: [OK] Popup interface eth0: Is deciding the IP information of eth0.

As you can see, the two NICs are configured successfully.
