查看网卡：ip addr
修改网卡网络地址配置：vim /etc/network/interfaces
配置模板：
auto ${网卡名}
iface ${网卡名} inet ${static}
address ${IP}
netmask ${netmask}
gateway ${gateway}
auto ens37 iface ens37 inet static address 10.10.100.31 netmask 255.255.255.0 gateway 10.10.100.2
然后重启网卡：systemctl restart networking或者/etc/init.d/networking restart
或重启设备（重启网卡报错就重启设备）：reboot
