vps更换服务器后网卡不通的处理办法 更换网卡vps主机不通,在更换服务器的时候linux的主机时常遇到这类问题。 具体处理办法是: 1.查看目前使用网卡和配置的实际mac地址(下面的使用的eth1) [root@localhost ~]# vi /etc/udev/rules.d/70-persistent-net.rules 显示信息如下:(可能会多出一段是eth_sudu的) # 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. # net device () # net device () SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:22:*", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # net device () SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:4a:ff:2a:23:3d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" ~ 注意:ATTR{address}=="00:4a:ff:2a:23:3d"中的00:4a:ff:2a:23:3d为vps使用mac地址,如果与实际分配的不一样,必须修改成实际使用的 2.配置网卡信息(注意:ip,网关,掩码,配置与实际相同即可) vi /etc/sysconfig/network-scripts/ifcfg-eth1 显示信息如下: DEVICE="eth1" ONBOOT="yes" TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPADDR=192.168.0.7 NETMASK=255.255.255.0 GATEWAY=192.168.0.1 3.重启网卡服务 [root@localhost ~]# service network restart (责任编辑:IT) |
