ifconfig 先看下自己的ip和网卡
如确定是ens33
ens33 Link encap:Ethernet HWaddr 00:0c:29:79:73:ef
inet addr:192.168.2.239 Bcast:192.168.2.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe79:73ef/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:82 errors:0 dropped:0 overruns:0 frame:0
TX packets:90 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:27473 (27.4 KB) TX bytes:10975 (10.9 KB)
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:65536 Metric:1
RX packets:516 errors:0 dropped:0 overruns:0 frame:0

RX bytes:38512 (38.5 KB) TX bytes:38512 (38.5 KB)
第二步，修改ip
配置文件/etc/network/interfaces
改成如下
# interfaces(5) file used by ifup(8) and ifdown(8)
source /etc/network/interfaces.d/*
auto ens33
iface ens33 inet static
address 192.168.2.239
netmask 255.255.255.0
gateway 192.168.2.255
dns-nameservers 8.8.8.8
auto lo
iface lo inet loopback
第三步 重启系统
