su root

 设置静态IP

修改文件:sudo vim /etc/dhcpcd.conf

interface eth0

static ip_address=192.168.0.10/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

interface wlan0

static ip_address=192.168.0.200/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

eth0是有线的配置  , wlan0是无线配置

ip_address就是静态IP , 后面要接/24

routers是网关

static domain_name_servers是DNS
