CentOS Linux解决Device eth0 does not seem to be present
今天早上打开xshell链接虚拟机,突然链接不上。然后进入虚拟机执行 ifconfig 或者 ip addr list 命令发现eth0 不见。然后执行重启网卡命令发现
解决办法: 首先,打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示:
# vi /etc/udev/rules.d/70-persistent-net.rules # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x1022:0x2000 (pcnet32) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9 7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x1022:0x2000 (pcnet32) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1 7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
记录下,eth1网卡的mac地址00:0c:29:50:bd:17 接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0 将 DEVICE="eth0" 改成 DEVICE="eth1" , 将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17" 最后,重启网络 # service network restart 或者 # /etc/init.d/network restart
然后瞬间就满血复活,xshell链接也正常了。
