一、修改网卡名

1. 编辑接口配置文件，添加参数

sudo vi /etc/default/grub

修改前

GRUB_CMDLINE_LINUX=""

修改后

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

2. 更新grub

sudo update-grub

若提示没有此命令，请先输入安装命令

sudo apt-get install grub2-common

3. 修改网卡名称并设置固定IP地址

修改网卡接口配置文件

sudo vi /etc/network/interfaces

修改前（网卡名不同机器会不一样，请根据实际情况修改）

# The primary network interface
auto eno13
iface eno13 inet dhcp

修改后

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.91.11
netmask 255.255.255.0
gateway 192.168.91.1
dns-nameservers 192.168.91.1

4.更换源为阿里源

备份源文件

sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

新建配置文件

 sudo vi /etc/apt/sources.list

添加如下内容

deb-src http://archive.ubuntu.com/ubuntu xenial main restricted
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe

5. 搞定，重启系统后生效
