Ubuntu配置静态ip

Ubuntu

首先设置VMware workstation为NAT模式，然后设置NAT，查看网关，子网掩码，子网ip等信息，之后配置静态ip会用到，之后点击确定保存以上设置；

然后查看网卡，使用ifconfig，如图所示，网卡名称为eno16777736。

donaldhan@ubuntu:~$ ifconfig
eno16777736 Link encap:Ethernet  HWaddr 00:0c:29:11:70:73  
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:34 errors:0 dropped:0 overruns:0 frame:0
          TX packets:131 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:5700 (5.7 KB)  TX bytes:23827 (23.8 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:1332 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1332 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:102291 (102.2 KB)  TX bytes:102291 (102.2 KB)

配置静态ip，修改/etc/network/interfaces，增加如下配置

root@ubuntu:~# vim /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
# 配置环路地址
auto lo
iface lo inet loopback
## 网卡名
auto eno16777736
# 配置静态ip
iface eno16777736 inet static
# 配置动态ip
#inface eno16777736 inet dhcp
address 192.168.5.128
netmask 255.255.255.0
gateway 192.168.5.2
~                     

注意：文件路径不能错，错的话ip配置将不会生效。

配置DNS， vim /etc/resolvconf/resolv.conf.d/base

root@ubuntu:~# vim /etc/resolvconf/resolv.conf.d/base

root@ubuntu:~# cat /etc/resolvconf/resolv.conf.d/base
114.114.114.114
223.5.5.5
8.8.8.8
root@ubuntu:~#

这里我配置了多个DNS，如图所示，114.114.114.114是国内移动、电信和联通通用的DNS，8.8.8.8是Google公司提供的DNS，该地址是全球通用,223.5.5.5 为阿里的DNS。

执行resolvconf -u将DNS配置更新到/etc/resolv.conf中 root@ubuntu:~# resolvconf -u

注意：若修改/etc/resolv.conf的话，最好同时还修改/etc/resolvconf/resolv.conf.d/base，因为每次重启，后者会向前者更新，若后者没有想过配置，DNS配置会失效

重启网络，使配置生效:

/etc/init.d/networking restart

使用ifconfig查看配置是否生效

root@ubuntu:/etc/network# ifconfig
