Ubuntu固定ip

步骤：

1、sudo vim /etc/network/interfaces

　　加入下列内容
　　auto eth0#此处查看自己的ip信息是eth0还是eth1等等
　　iface eth0 inet static
　　address 192.168.xx.xx#设置要固定的ip
　　netmask 255.255.255.0
　　gateway 192.168.xx.2    # 虚拟机中网关一般默认为2
　　gateway 192.168.0.1         #在实体机中需要填写路由器的一般默认为这个  
　　broadcast 192.168.10.255

2. sudo vim /etc/NetworkManager/NetworkManager.conf

将managed=false 改成true

3.sudo vim /etc/resolvconf/resolv.conf.d/base

 

     加入nameserver为你的DNS即可

     nameserver 114.114.114.114

     nameserver 8.8.8.8

 4、ping域名进行测试

yun@yun-virtual-machine:~$ ping www.baidu.com
PING www.a.shifen.com (180.149.132.151) 56(84) bytes of data.
64 bytes from 180.149.132.151: icmp_seq=1 ttl=128 time=30.7 ms
64 bytes from 180.149.132.151: icmp_seq=2 ttl=128 time=32.5 ms
64 bytes from 180.149.132.151: icmp_seq=3 ttl=128 time=33.1 ms
64 bytes from 180.149.132.151: icmp_seq=4 ttl=128 time=37.7 ms

64 bytes from 180.149.132.151: icmp_seq=6 ttl=128 time=31.3 ms

5、为验证ip地址是否永久性，重启操作系统

      reboot
