ip: 192.168.1.10/24
网关：192.168.1.1
DNS：192.168.1.254

/etc/network/interfaces原始文件内容为：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).source /etc/network/interfaces.d/*# The loopback network interface
auto lo
iface lo inet loopback# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

修改后为：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).source /etc/network/interfaces.d/*# The loopback network interface
auto lo
iface lo inet loopback# The primary network interface
#allow-hotplug eth0
auto eth0
iface eth0 inet staticaddress 192.168.1.10netmask 255.255.255.0gateway 192.168.1.1

然后就是DNS：
/etc/resolv.conf增加：

nameserver 202.96.134.133

基本设置完成，重启网络服务以应用更改：

systemctl restart networking
