For more information, see interfaces(5).source /etc/network/interfaces.d/*# The loopback network interfaceauto loiface lo inet loopback# The primary network interfaceauto ens33iface ens33 inet static address 10.0.0.50 netmask 255.255.255.0 network 10.0.0.0 broadcast 10.0.0.255 gateway 10.0.0.2 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 10.0.0.

DHCP动态IP

以DHCP方式配置网卡

编辑文件vi /etc/network/interfaces并用下面的行来替换有关eth0的行:# The primary network interface - use DHCP to find our addressauto eth0iface eth0 inet dhcp

用下面的命令使网络设置生效

/etc/init.d/networking restart

设置主机名称(hostname)

使用下面的命令来设置当前主机的主机名称:

vim /bin/hostname

newname系统启动时,它会从/etc/hostname来读取主机的名称.

配置DNS

vim /etc/resolv.conf
