vmware 虚拟机添加新网卡后无网卡配置文件

vmware为虚拟机添加网络适配器后，系统/etc/sysconfig/network-scripts/下无网卡配置文件ifcfg-eth*

1、查看是否存在新网卡信息

[root@localhost ~]# ip a #查看是否存在新网卡信息，如下所示，eth1为新增的网卡
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:4c:f2:06 brd ff:ff:ff:ff:ff:ff
    inet 192.168.152.10/24 brd 192.168.152.255 scope global eno16777736
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fe4c:f206/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:4c:f2:10 brd ff:ff:ff:ff:ff:ff
    inet 192.168.84.138/24 brd 192.168.84.255 scope global dynamic eth1
       valid_lft 1668sec preferred_lft 1668sec
    inet6 fe80::20c:29ff:fe4c:f210/64 scope link
       valid_lft forever preferred_lft forever
4: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN
    link/ether 52:54:00:9a:f8:30 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
5: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 500
    link/ether 52:54:00:9a:f8:30 brd ff:ff:ff:ff:ff:ff

2、拷贝一份现有的网卡配置文件重命名后配置网络信息

#拷贝后的网卡配置文件命名与ip a显示的需保持一致，如ip a显示的是eth1，则新网卡配置文件为[ifcfg-eth1]
[root@localhost ~]# cp /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eth1
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
UUID=8660b30a-82aa-4881-9d8a-b776a5a776d9
DEVICE=eth1 #设备名
ONBOOT=yes
#HWADDR=00:0C:29:4C:F2:06
#IPADDR=192.168.152.10
#NETMASK=255.255.255.0

3、配置完成后重启网络:

[root@localhost ~]# service network restart
