重启网卡生效
centos6的网卡重启方法:service network restart
centos7的网卡重启方法:systemctl restart network
ok
其它ip相关命令
centos 查看网关的命令
1.ifconfig -a 和 cat /etc/resolv.conf (主要查看ip/netmask和dns)
2.netstat -rn
3.cat /etc/sysconfig/network
4.cat /etc/sysconfig/network-scripts/ifcfg-eth0
5.traceroute 第一行就是自己的网关
6.ip route show
7.route -n
复制虚拟机后,开机选择 移动虚拟机 网卡启动失败
[root@c1node01 ~]# service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]
方案1
rm -rf /etc/udev/rules.d/70-persistent-net.rules
重启虚拟机
方案2
/etc/sysconfig/network-scripts/ifcfg-eth0
重命名为eth1
打开文件
DEVICE="eth1"
删掉uuid、物理地址
重启网卡
