网卡eth0 未识别的端口
CentOS 虚拟机
设置完ip地址,重启网络服务报错:
# service network restart
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Error: No suitable device found: no device found for connection ‘System eth0‘. [FAILED]
解决方法:
# vi /etc/udev/rules.d/70-persistent-net.rules #网络在启动的时候会去读取该配置文件 /etc/udev/rules.d/70-persistent-net.rules 信息
查看文件信息发现有两个网卡,eth0和eth1:
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:fd:8b:ad", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:57:13:79", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
查看本机的ip配置文件,发现只有一个eth0:
若想设置eth0则可以把上面70-persistent-net.rules文件中的eth1的mac地址复制给eth0,并注释掉eth1,并更新到ifcfg-eth0中的mac地址:
70-persistent-net.rules:
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:57:13:79", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:57:13:79", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
-------------------------------------
ifcfg-eth0:
重启网络服务,网卡正常:
# service network restart
该虚拟机为克隆出来的,可能就导致网卡1的mac地址不能用了。
