ubuntu设置静态ip

找到文件并作如下修改

sudo vim /etc/network/interfaces

# The primary network interface
auto eno1
iface eno1 inet static
        address 192.168.1.111
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 202.101.172.35 202.101.172.46

修改dns解析

因为以前是dhcp解析，所以会自动分配dns服务器地址

而一旦设置为静态ip后就没有自动获取到的dns服务器了

要自己设置一个

sudo vim /etc/resolv.conf

写上一个公网的DNS,以下为浙江杭州电信DNS

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 202.101.172.35
nameserver 202.101.172.46

（注意：8.8.8.8是谷歌的DNS服务器，但是解析速度慢，还是找到一个国内的dns来用）

重启网卡

sudo /etc/init.d/networking restart
