centos6.9 虛擬機 識別 新網卡

1、ifconfig看不到新網卡： [root@drbd2 ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:38:DD:03 inet addr:192.168.1.107 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe38:dd03/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1199 errors:0 dropped:0 overruns:0 frame:0 TX packets:252 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:125240 (122.3 KiB) TX bytes:42908 (41.9 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:45 errors:0 dropped:0 overruns:0 frame:0 TX packets:45 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5945 (5.8 KiB) TX bytes:5945 (5.8 KiB) 2、ip addr可以看到新網卡eth1，記錄mac地址： [root@drbd2 ~]# ip addr 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 inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:38:dd:03 brd ff:ff:ff:ff:ff:ff inet 192.168.1.107/24 brd 192.168.1.255 scope global eth0 inet6 fe80::20c:29ff:fe38:dd03/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 00:0c:29:38:dd:0d brd ff:ff:ff:ff:ff:ff 3、拷貝eth0配置文件威eth1，並且更改mac地址、IP地址等： [root@drbd2 ~]# cd /etc/sysconfig/network-scripts/ [root@drbd2 network-scripts]# cp ifcfg-eth0 ifcfg-eth1 [root@drbd2 network-scripts]# vi ifcfg-eth ifcfg-eth0 ifcfg-eth1 [root@drbd2 network-scripts]# vi ifcfg-eth1 DEVICE="eth1" BOOTPROTO="static" BROADCAST="192.168.136.255" HWADDR="00:0c:29:38:dd:0d" IPADDR="192.168.136.7" IPV6INIT="yes" IPV6_AUTOCONF="yes" NETMASK="255.255.255.0" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" 4、重啟網卡並用ifconfig進行驗證。 [root@drbd2 network-scripts]# /etc/init.d/network restart 正在關閉接口 eth0： [確定] 關閉環回接口： [確定] 彈出環回接口： [確定] 彈出界面 eth0： Determining if ip address 192.168.1.107 is already in use for device eth0...

[確定] [root@drbd2 network-scripts]# ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:38:DD:03 inet addr:192.168.1.107 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe38:dd03/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10873 errors:0 dropped:0 overruns:0 frame:0 TX packets:1983 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1097307 (1.0 MiB) TX bytes:328774 (321.0 KiB) eth1 Link encap:Ethernet HWaddr 00:0C:29:38:DD:0D inet addr:192.168.136.7 Bcast:192.168.136.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe38:dd0d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:12 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:720 (720.0 b) TX bytes:828 (828.0 b) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:155 errors:0 dropped:0 overruns:0 frame:0 TX packets:155 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:43225 (42.2 KiB) TX bytes:43225 (42.2 KiB)
