Debian-Linux配置网卡网络方法

https://www.cnblogs.com/saryli/p/11807223.html

Debian不同于centos系统，网卡配置不是在/etc/sysconfig/network-scrip里面，而是在/etc/network/interfaces里面

vi /etc/sysconfig/network-scripts/ifcfg-eth0

vi /etc/network/interfaces

在ubuntu下，还可以指定控制哪个网卡(其中eth0为网卡名)：指定网卡重启
ifdown eth0
ifup eth0

在ubuntu下，网络重启 /etc/init.d/networking restart service networking restart

Linux 下网卡重启的命令为：

/etc/init.d/network restart 或者是 /etc/init.d/networking restart
或者重启网络服务：
service network restart

systemctl restart network

#ifdown <interface_name> && ifup <interface_name>

ifdown eth0 && ifup eth0

特别是在ssh登录远程主机的情况下,一定要像上面这样在一条命令里执行ifdown和ifup,否则,如果先执行ifdown,则再也没有机会执行ifup了。

配置为静态IP

auto eth0 #开机自动启动
iface eth0 inet static #静态IP设置
address 192.168.0.10 #本机IP
netmask 255.255.255.0 #子网掩码
gateway 192.168.0.1 #网关
