root@rise-rs-171:/etc/network# mii-tool
eth2: negotiated 1000baseT-FD flow-control, link ok
eth3: autonegotiation restarted, no link网络

 

发现网卡绑定在eth2和eth3,以前正常应该是绑定在eth0和eht1 ,询问同事,原来这台机器以前维修过换了块主板,致使MAC地址变了ide

缘由:之前用rulles绑定了MAC地址,形成eth0和eth1被占用了,只能按顺序排下去oop

root@rise-rs-171:/etc/udev/rules.d# cat 70-persistent-net.rules

# PCI device 0x8086:/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.0 (igb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="e4:11:5b:e4:0f:80", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.1 (igb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="e4:11:5b:e4:0f:81", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x8086:/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.0 (igb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="80:c1:6e:6d:f8:ba", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"spa

 

发现新的MAC地址变为80:c1:6e:6d:f8:ba3d

 

因而删除root@rise-rs-171:/etc/udev/rules.d# rm -f 70-persistent-net.rulesrest

从新配置网络设置,重启机器reboot便可orm

root@rise-rs-171:/etc/network# cat interfaces
# The loopback network interface
auto lo
iface lo inet loopbackblog

# The primary network interfaceci

auto eth0
