VMware 虚拟机添加 2 张网卡设置 NAT 与桥接网络

2022-08-09 15:03:00 【tom马】

一、NAT 方式

1、选择 Wmnet8

2、配置 NAT

3、配置 DHCP

4、虚拟机设置

二、桥接方式

1、选择 Vmnet0，网卡选择本地的网卡

2、虚拟机添加一张网卡

3、选择桥接

三、验证

1、登陆虚拟机

[[email protected] ~]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.110  netmask 255.255.255.0  broadcast 192.168.2.255
        inet6 fe80::6963:2857:478c:ecd4  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:fb:5a:a1  txqueuelen 1000  (Ethernet)
        RX packets 68  bytes 8215 (8.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 82  bytes 9551 (9.3 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

ens37: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.100  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::a379:a4d:829a:6d0e  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:fb:5a:ab  txqueuelen 1000  (Ethernet)
        RX packets 33  bytes 1992 (1.9 KiB)
        RX errors 0  dropped 2  overruns 0  frame 0
        TX packets 19  bytes 1412 (1.3 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

2、查看路由表

[[email protected] ~]# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         gateway         0.0.0.0         UG    100    0        0 ens33
default         gateway         0.0.0.0         UG    101    0        0 ens37
192.168.1.0     0.0.0.0         255.255.255.0   U     101    0        0 ens37
192.168.2.0     0.0.0.0         255.255.255.0   U     100    0        0 ens33

3、配置第一张网卡 NAT 静态IP

cd /etc/sysconfig/network-scripts/

[[email protected] network-scripts]# vim ifcfg-ens33


# 内容
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=5257be0a-5ed5-40d5-ba3e-1f1f2b16c3bd
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.2.110
NETMASK=255.255.255.0
GATEWAY=192.168.2.2
DNS1=8.8.8.8

4、配置第二张网卡静态IP

cp ifcfg-ens3 ifcfg-ens37

# 生成网卡 UUID
[[email protected] network-scripts]# uuidgen
207d5d84-b67d-4e13-8a0b-f3bdb1a507da

# 修改
[[email protected] network-scripts]# vim ifcfg-ens37

# UUID，NAME，DEVICE，IPADDR GATEWAY
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
UUID=207d5d84-b67d-4e13-8a0b-f3bdb1a507da
NAME=ens37
DEVICE=ens37
ONBOOT=yes
IPADDR=192.168.1.100
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114

5、本地电脑验证
