Debian 9：设置网络源，更换镜像源，配置apt-get源，解决下载软件慢

前言

Debian使用国外镜像源，在国内使用会造成更新软件慢或者找不到等问题，装完系统，应对软件源进行设置，改为国内源，下载速度就变快。

阿里源：

1. 打开站点 https://opsx.alibaba.com/mirror
2. 找到debian相关内容，点开右边debian使用帮助页面
3. 复制源地址到剪切板

• debian 6.x (squeeze)
• debian 7.x (wheezy)
• debian 8.x (jessie)
• debian 9.x (stretch)
  需要哪个系统的则自行替换对应版本

操作步骤

以阿里源为例子，自行替换所属源

• 设置源

# 切换到root权限下
cp /etc/apt/sources.list /etc/apt/sources.list.bak # 备份原有文件
# 打开文件编辑
vi /etc/apt/sources.list

# 替换内容为刚才复制的内容
deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main
deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
# 保存并退出

• 更新操作

# 配置好之后更新软件包列表
apt-get update
# 升级系统所有软件
apt-get upgrade
# 升级系统版本
apt-get dist-upgrade

忠告

不要同时配置多个源，同一仓库的源启用一个即可，否则容易引起混乱。
