（YDW）Ubuntu下静态配网

1、ifconfig查看状态

linux@ubuntu:~/yudw2018$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0c:29:12:ea:0e  
          inet6 addr: fe80::20c:29ff:fe12:ea0e/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:360 errors:0 dropped:0 overruns:0 frame:0
          TX packets:158 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:25731 (25.7 KB)  TX bytes:32112 (32.1 KB)
          Interrupt:19 Base address:0x2000 

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:16436  Metric:1
          RX packets:500 errors:0 dropped:0 overruns:0 frame:0
          TX packets:500 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:38708 (38.7 KB)  TX bytes:38708 (38.7 KB)

linux@ubuntu:~/yudw2018$ 

  eth0:第一块有线网卡
        sudo ifconfig eth0  down  关闭网卡
        sudo ifconfig eth0  up    开启网卡

2、添加ip地址，子网掩码，网关

linux@ubuntu:~/yudw2018$ sudo vi /etc/network/interfaces 

  1 auto lo
  2 iface lo inet loopback
  3 
  4 
  5 auto eth0
  6 
  7 #动态分配
  8 #iface eth0 inet dhcp
  9 #=====================
 10 
 11 #静态指定ip地址
 12 iface eth0 inet static
 13 address 192.168.5.105
 14 netmask 255.255.255.0                                                                                            
 15 gateway 192.168.5.1
 16 

3、设置域名解析器

linux@ubuntu:~/yudw2018$ sudo vi /etc/resolv.conf 

  1 # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  2 #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  3 
  4 nameserver 8.8.8.8                                                                                               
  5 

4、设置开机自运行脚本

linux@ubuntu:~/yudw2018$ sudo vi /etc/rc.local

  1 #!/bin/sh -e
  2 #
  3 # rc.local
  4 #
  5 # This script is executed at the end of each multiuser runlevel.
  6 # Make sure that the script will "exit 0" on success or any other
  7 # value on error.
  8 #
  9 # In order to enable or disable this script just change the execution
 10 # bits.
 11 #
 12 # By default this script does nothing.
 13 
 14 echo "nameserver 8.8.8.8" >> /etc/resolv.conf                                                                    
 15 
 16 exit 0
 17 

5、重启网络设备

linux@ubuntu:~/yudw2018$ sudo /etc/init.d/networking restart 
 * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces
 * Reconfiguring network interfaces...                                                                        [ OK ] 
linux@ubuntu:~/yudw2018$ 

6、测试

linux@ubuntu:~/yudw2018$ ping www.baidu.com
PING www.a.shifen.com (119.75.213.61) 56(84) bytes of data.

linux@ubuntu:~/yudw2018$ 

ping www.baidu.com出现以上情形证明成功。

7、如果还不好使，检查虚拟机网卡配置；手动设置ip
